14 Best Cold-Plunge Tubs and Chilliers to Keep You Cool and Refreshed

For most buyers, the AS ColdPlunge 1/3 HP Ice Bath Chiller and 148-Gallon Tub Kit is my best overall pick because it pairs a dedicated chiller with a roomy tub without stepping up to the largest setup. The 100-gallon chiller kits suit tighter spaces and smaller water volumes, while the 216-gallon bundle is aimed at buyers who want more room and a larger system. Across cold plunge tubs and chillers, the main tradeoffs are cooling convenience versus upfront setup, tub capacity versus floor space, and bundled simplicity versus buying a tub and chiller separately. Inflatable tubs can be easier to store, but their fit and insulation differ from more permanent setups. Read on for my full comparison and guidance on choosing the right combination.

Key Takeaways

• Bundled kits simplify matching: The AS ColdPlunge and 1stplunge tub-and-chiller kits combine key components, while standalone tubs and the AS ColdPlunge 1/3 HP chiller leave more compatibility decisions to the buyer.
• 148 gallons is the lineup’s middle ground: Several kits use this capacity, including oval options, giving buyers more room than the 100-gallon kits without moving to a 216-gallon tub.
• Capacity changes the cooling equation: The 216-gallon bundle and inflatable tub offer the most volume listed, but buyers should weigh the space and cooling demands of a larger water load.
• Inflatable designs favor flexibility: The 120-, 148-, and 216-gallon inflatable tubs offer a different setup path from bundled kits, but buyers seeking active cooling need to check chiller compatibility and connections.
• Not every buyer needs a chiller bundle: The AS ColdPlunge XL 100-Gallon tub and ALEKO 118-Gallon tub focus on tub-first ownership, while a standalone chiller can suit someone who already has a compatible vessel.

More Details on Our Top Picks

1. AS ColdPlunge XL 100-Gallon Portable Ice Bath Tub with Lid and Cover

   

   Best Portable Tub

   View on Amazon

   This is the tub-only pick for buyers who want full-body cold plunges without committing to a chiller bundle. Its 100-gallon capacity, inflatable construction, and included pump make setup and storage more flexible than the larger 216-gallon AS ColdPlunge bundle, though you’ll need to supply ice or connect a compatible chiller to cool the water. Five-layer foam insulation is intended to slow temperature changes, and inlet and outlet ports leave room to add a chiller later. The lid, dustproof cover, cushion, and storage bag make the package more self-contained than a bare tub. The tradeoff is that inflatable walls need careful handling; buyers seeking a more permanent, powered setup should look at the 1/3 HP kits instead.

   Pros:

   • 100-gallon capacity supports full-body immersion.
   • Weighs 9 pounds, making it easier to move and store than the larger bundled tubs.
   • Includes a pump, lid, cover, support rods, cushion, repair kit, and storage bag.
   • Inlet and outlet ports allow connection to a compatible chiller, while two drain taps aid emptying.

   Cons:

   • Does not include a chiller, so maintaining a set temperature requires ice or a separate unit.
   • Inflatable construction calls for care around sharp objects and rough surfaces.
   • A 100-gallon fill still takes dedicated floor space and requires a suitable place to drain.

   Best for: Apartment dwellers, renters, and first-time plunge buyers who want a portable 100-gallon tub and may add a chiller later.

   Not ideal for: People who want automatic temperature control or a rigid, permanently installed plunge; this tub relies on ice unless paired with a compatible chiller and its inflatable construction can be punctured.

   • Capacity:100 gallons
   • Weight:9 lbs
   • Insulation:5 layers of 10 mm EPE foam
   • Claimed cold retention:95% for 4 hours
   • Temperature range:-86°F to 140°F (-66°C to 60°C)
   • Chiller connection:Inlet and outlet ports
   • Drainage:Two drain taps
   • Included components:Tub, cloud lid, dustproof cover, support rods, inflatable cushion, drain pipe, air pump, repair kit, manual, and storage bag
   Our verdict

   “Choose this portable tub if you want a complete, movable soaking vessel and are comfortable sourcing cold water separately.”

2. AS ColdPlunge 1 HP Ice Bath Chiller and Insulated Tub Bundle, 216 Gallons

   

   Best for Large-Capacity Plunges

   View on Amazon

   For buyers prioritizing capacity and colder water, this bundle stands apart from the 100-gallon AS ColdPlunge 1/3 HP kit. Its 216-gallon tub and 1 HP chiller are built for a larger-volume setup, with cooling down to 37°F rather than 42°F. The included external pump and replaceable filter cartridge circulate and filter water, while the insulated lid helps limit heat gain between sessions. That combination suits households or shared-use spaces where multiple people may want access to a larger plunge. The compromise is practical: 216 gallons plus external equipment demands substantial room, and the cartridge adds a recurring maintenance task. Buyers with limited space or a simpler personal routine may find the smaller 100-gallon kit easier to live with.

   Pros:

   • 216-gallon capacity provides more room than the 100-gallon kits in this lineup.
   • The 1 HP chiller is specified to cool water to 37°F, colder than the 42°F 1/3 HP kits.
   • Tub, chiller, external pump, filtration system, hoses, and insulated lid are bundled together.
   • Insulated tub and lid help reduce heat gain between plunges.

   Cons:

   • The tub and external equipment require considerably more space than a 100-gallon setup.
   • The 5-inch filter cartridge is replaceable and needs periodic maintenance.
   • The listed warranty is one year.

   Best for: Households, studios, or shared-use spaces that need a large-capacity tub and want a bundled chiller capable of reaching 37°F.

   Not ideal for: Solo users with limited indoor or outdoor space, or buyers who want minimal upkeep; the 216-gallon tub needs a large footprint and its filter cartridge must be replaced periodically.

   • Chiller power:1 HP
   • Tub capacity:216 gallons
   • Minimum cooling temperature:37°F (2.7°C)
   • Filter:5-inch replaceable filter cartridge
   • Warranty:1 year
   • Included components:Chiller, pump and filter system, hoses, tub, insulated lid, hand pump, repair kit, and portable storage bag
   Our verdict

   “Pick this bundle if you have room for a large plunge and want the lineup’s lower stated cooling target in a ready-to-connect package.”

3. AS ColdPlunge 1/3 HP Ice Bath Chiller and 100-Gallon Cold Plunge Tub Kit

   

   Best for Beginners

   View on Amazon

   This is the most approachable powered kit for a buyer who wants a personal-size tub and temperature control in one package. The 1/3 HP chiller maintains a selected temperature down to 42°F, and its built-in circulation pump and washable metal filter keep the water moving without adding a replaceable cartridge to the routine. Compared with the portable AS ColdPlunge XL 100-gallon tub, this kit adds active cooling; compared with the 148-gallon kits, it takes less water and space. The option to use the chiller with a standard bathtub also gives owners another setup path. Its limits are clear: 42°F is warmer than the 1 HP bundle’s 37°F target, and the tub and chiller may ship separately, delaying a complete setup.

   Pros:

   • Includes both a 100-gallon tub and a 1/3 HP chiller that maintains a selected temperature.
   • Built-in circulation pump reduces the need for separate pumping equipment.
   • Washable metal filter avoids routine cartridge replacement.
   • Can be used with the supplied tub or a standard bathtub.

   Cons:

   • The 42°F minimum is not as cold as the 1 HP, 216-gallon bundle’s 37°F target.
   • Chiller and tub ship separately and may arrive at different times.
   • A 100-gallon tub still needs a suitable footprint and a plan for filling and draining.

   Best for: First-time cold-plunge buyers who want a 100-gallon tub, automatic temperature maintenance, and a reusable filter without stepping up to a larger kit.

   Not ideal for: People seeking the coldest stated water temperature or a larger shared tub; the chiller is rated to 42°F and the included vessel holds 100 gallons.

   • Chiller power:1/3 HP
   • Tub capacity:100 gallons
   • Minimum cooling temperature:42°F
   • Tub material:Reinforced PVC
   • Tub insulation:10 mm EPE
   • Filter:Washable metal mesh
   • Warranty:1 year
   • Included components:Chiller, tub, insulated lid, hand pump, repair kit, and portable storage bag
   Our verdict

   “Choose this kit for a compact, powered entry into cold plunging if 42°F suits your routine and you can accommodate separate deliveries.”

   → See it on Amazon →

4. AS ColdPlunge Ice Bath Chiller and 148-Gallon Cold Plunge Tub Kit

   

   Best for a Roomier Tub

   View on Amazon

   This kit gives you more tub capacity than the 100-gallon 1/3 HP option without moving to the 216-gallon footprint of AS ColdPlunge’s 1 HP bundle. Its 148-gallon oval tub pairs reinforced PVC and Oxford fabric with 10 mm EPE insulation and a support frame, adding room while keeping the same 42°F cooling target as the smaller kit. The chiller’s built-in pump and washable metal filter keep the system simpler than the separate-pump, replaceable-filter arrangement in the other 148-gallon AS kit. An LED touchscreen handles temperature controls, and the chiller can also work with a standard bathtub using the included submersible pump. The tradeoff is that the tub and chiller ship separately, and the larger vessel needs more floor space and water than the 100-gallon alternative.

   Pros:

   • 148-gallon capacity offers more room than the 100-gallon 1/3 HP kit.
   • Built-in circulation pump and washable metal filter simplify the equipment setup and filter care.
   • Reinforced PVC, Oxford fabric, insulation, and a support frame form the oval tub structure.
   • LED touchscreen controls the chiller, which can also be used with a standard bathtub.

   Cons:

   • The 42°F cooling target is warmer than the 1 HP bundle’s stated 37°F minimum.
   • Chiller and tub ship separately and may arrive on different days.
   • The larger capacity calls for more floor space and more water than the 100-gallon kit.

   Best for: Buyers who want more room than a 100-gallon tub provides, prefer a built-in pump and washable filter, and have space for an oval setup.

   Not ideal for: People with tight spaces or a preference for one coordinated delivery; the 148-gallon tub has a larger footprint and the chiller and tub may arrive on different days.

   • Chiller power:1/3 HP
   • Tub capacity:148 gallons
   • Minimum cooling temperature:42°F
   • Tub shape:Oval
   • Tub materials:Reinforced PVC, Oxford fabric, and 10 mm EPE insulation
   • Filter:Washable metal mesh
   • Controls:LED touchscreen
   • Warranty:1 year
   Our verdict

   “Choose this kit if the 100-gallon option feels cramped but you want a built-in pump and washable filter rather than the larger 1 HP setup.”

   → See it on Amazon →

5. AS ColdPlunge 1/3 HP Ice Bath Chiller and 148-Gallon Tub Kit

   

   Best for Filtered Circulation

   View on Amazon

   This 148-gallon kit favors a separate circulation setup over the all-in-one pump arrangement found in the other AS ColdPlunge 148-gallon kit. It includes an external pump, insulated hoses, quick-connect fittings, and a replaceable 20-micron filter; those pieces give buyers a defined filtration path, but also add components to place and maintain. The 1/3 HP chiller cools to 42°F and holds a selected temperature through an LED touchscreen, matching the cooling target of the built-in-pump 148-gallon kit rather than the 1 HP bundle’s colder 37°F target. Reinforced PVC, Oxford fabric, 10 mm EPE insulation, and a support frame form the oval tub. The key tradeoff is filter upkeep and separate shipments; choose the other 148-gallon kit if a washable filter and built-in pump appeal more.

   Pros:

   • 148-gallon oval tub gives more room than the 100-gallon kit.
   • External pump, insulated hoses, and quick-connect fittings are included for circulation setup.
   • Replaceable 20-micron filter provides a specified filtration level.
   • Chiller maintains a selected temperature down to 42°F and supports standard bathtub use with a submersible pump.

   Cons:

   • The external pump and associated fittings add equipment to position and connect.
   • The replaceable filter requires periodic replacement, unlike the washable metal filter in the other 148-gallon kit.
   • Chiller and tub ship separately and may arrive at different times.

   Best for: Cold-plunge owners who want a 148-gallon tub with an external pump, insulated hoses, quick-connect fittings, and a defined fine-filtration setup.

   Not ideal for: Buyers seeking the simplest equipment layout or avoiding recurring filter replacements; this kit uses an external pump and replaceable filter, and its tub and chiller may ship separately.

   • Chiller power:1/3 HP
   • Cooling temperature:Down to 42°F
   • Tub capacity:148 gallons
   • Tub shape:Oval
   • Insulation:10 mm EPE
   • Filter:Replaceable 20-micron filter
   • Warranty:1 year
   • Included components:Chiller, external pump, filter system, insulated hoses, quick-connect fittings, and tub
   Our verdict

   “Pick this kit if you want the 148-gallon size and prefer its external pump and 20-micron filter setup over a built-in-pump design.”

   → See it on Amazon →

6. AS ColdPlunge 1/3 HP Ice Bath Chiller and 100-Gallon Tub Bundle

   

   Best Complete Setup for a Compact Plunge

   View on Amazon

   This bundle makes sense for buyers who want a matched tub-and-chiller system without sourcing the main components separately. Its 100-gallon reinforced PVC tub is smaller than the 148-gallon oval kit, which can mean less water to cool and a more manageable footprint, though it gives tall users less room to stretch out. The 1/3 HP chiller reaches 42°F, while the insulated tub, external circulation pump, and replaceable 20-micron filter support a maintained setup rather than repeated ice runs. I also like that the pump can serve a standard bathtub, adding flexibility if the included tub is not the preferred vessel. The tradeoffs are ongoing filter replacement and separate shipping, which can leave the system incomplete until both boxes arrive.

   Pros:

   • Includes a 1/3 HP chiller, insulated tub, circulation pump, and filter
   • Chiller cools water to 42°F with LED touchscreen controls
   • Pump can also circulate water in a standard bathtub
   • 10 mm EPE insulation and an insulated lid help limit heat gain

   Cons:

   • Replaceable filter cartridges add recurring upkeep
   • Tub and chiller ship separately and may arrive at different times

   Best for: Home users who want a ready-to-connect chiller and insulated tub, and prefer a smaller setup than a 148-gallon model.

   Not ideal for: Taller users who want extra room to stretch out, or buyers who need every component to arrive together.

   • Chiller power:1/3 HP
   • Minimum water temperature:42°F
   • Tub capacity:100 gallons
   • Tub material:Reinforced PVC
   • Insulation:10 mm EPE
   • Filter:20-micron replaceable filter
   • Controls:LED touchscreen
   • Warranty:1 year
   Our verdict

   “Choose this bundle for a compact, all-in-one cold plunge setup; pick the 148-gallon oval kit if extra immersion room matters more.”

   → See it on Amazon →

7. AS ColdPlunge 1/3 HP Cold Plunge Chiller

   

   Best Chiller Upgrade for an Existing Tub

   View on Amazon

   For someone who already owns a compatible tub, this standalone unit avoids paying for another vessel. The built-in circulation pump and washable metal filter also make its upkeep different from the AS ColdPlunge 1/3 HP Ice Bath Chiller and 100-Gallon Tub Bundle, which includes a replaceable cartridge filter. At 35 lb and under 15 inches across, it is a relatively compact freestanding option, and the included hoses and fittings simplify connecting it to a tub or bathtub. The listed cooling target is inconsistent: the description cites both 42°F and 39°F, so I would confirm the supported minimum before buying. Unlike the bundles, this chiller supplies no plunge tub, making it a poor fit for anyone starting from scratch.

   Pros:

   • Built-in circulation pump reduces the need for a separate external pump
   • Washable metal filter avoids regular cartridge replacement
   • Includes insulated hoses, quick-connect fittings, and a submersible pump
   • Compact 35 lb freestanding unit with LED touchscreen controls

   Cons:

   • A compatible tub or bathtub setup must be supplied separately
   • Product details conflict on whether the minimum temperature is 42°F or 39°F

   Best for: Owners of a compatible cold plunge tub or bathtub who want active cooling, circulation, and a reusable filter in one unit.

   Not ideal for: First-time buyers without a tub, or shoppers who need a clearly verified minimum temperature before purchase.

   • Cooling capacity:1/3 HP
   • Listed cooling temperature:42°F; description also cites 39°F
   • Wattage:600 watts
   • Voltage:110V
   • Capacity:79 gallons
   • Dimensions:11.8 × 14.9 × 12.6 in
   • Weight:35 lb
   • Warranty:1 year
   Our verdict

   “Choose this standalone chiller if you already have a compatible vessel and prefer a washable filter over a complete tub bundle.”

   → See it on Amazon →

8. AS ColdPlunge XL 120-Gallon Inflatable Ice Bath Tub with Insulated Lid and Step Stool

   

   Best Chiller-Compatible Tub for Flexible Setups

   View on Amazon

   This tub is for buyers who need the vessel but want to choose a chiller separately. Its 120-gallon capacity sits between the 100-gallon bundle and the 148-gallon AS ColdPlunge XXL oval tub, offering more immersion room than the former without matching the latter’s larger footprint. Reinforced fiberglass and PVC, plus a tear-resistant polyester outer layer, are intended to add structure to an inflatable format; the included step stool can make getting in and out easier. Chiller compatibility and 1/2-inch ports leave room to build a circulating system, but the chiller is not included, unlike the 100-gallon bundle. The inflatable build also has a stability tradeoff versus a rigid tub, and buyers should allow space for setup and access even though inflation is described as taking under five minutes.

   Pros:

   • 120-gallon capacity supports full-body immersion for users up to 6’9″
   • Reinforced fiberglass, PVC, and tear-resistant polyester layers
   • Insulated lid helps retain temperature and keep debris out
   • Includes an inflatable step stool, hand pump, and carry bag

   Cons:

   • Chiller must be purchased separately
   • Inflatable construction may feel less stable than a rigid tub

   Best for: Buyers who already own a chiller, or want to choose one separately, and need a portable tub with more room than a 100-gallon model.

   Not ideal for: Shoppers seeking a complete chiller-and-tub package or a rigid, highly stable plunge vessel.

   • Capacity:120 gallons
   • Dimensions:35.4 in diameter × 31.5 in height
   • Materials:Reinforced fiberglass, PVC, and tear-resistant polyester
   • Maximum user height:6’9″
   • Setup time:Under 5 minutes
   • Port size:1/2-inch inlet and outlet
   • Ports:Inlet and outlet with shut-off valves
   • Included accessories:Insulated lid, inflatable step stool, hand pump, and carry bag
   Our verdict

   “Choose this tub if portability and a roomy chiller-compatible vessel matter more than having a chiller included.”

9. AS ColdPlunge 1/3 HP Ice Bath Chiller and 148-Gallon Oval Tub Kit

   

   Best Complete Kit for Maximum Immersion Room

   View on Amazon

   Among the complete systems here, this kit prioritizes immersion space: its 148-gallon oval tub is substantially roomier than the 100-gallon bundle, making it the better match for buyers who feel cramped in smaller plunges. The package pairs that tub with a 1/3 HP chiller rated down to 42°F, an external pump, and a 5-inch, 20-micron replaceable filter. Insulated construction and a lid help support temperature retention, while the included submersible pump and fittings allow circulation in a standard bathtub as well. The larger water volume is the tradeoff: it calls for more space and more water to cool than the smaller bundle. Like that 100-gallon kit, it also uses replacement filter cartridges, and separate shipping can delay completion of the setup.

   Pros:

   • 148-gallon oval tub offers more room than the 100-gallon bundle
   • Includes a 1/3 HP chiller rated to cool water to 42°F
   • External and submersible pumps support tub or bathtub circulation
   • Insulated tub, lid, and hoses support temperature retention

   Cons:

   • Larger capacity requires more space and water than the 100-gallon kit
   • Replaceable filter cartridges require ongoing replacement
   • Tub and chiller may arrive separately

   Best for: Buyers who want a complete chiller-and-tub package with generous room for full-body immersion.

   Not ideal for: People with limited floor space, or buyers who want a smaller water volume and simpler replacement-filter upkeep.

   • Chiller power:1/3 HP
   • Cooling temperature:Down to 42°F
   • Tub capacity:148 gallons
   • Tub shape:Oval
   • Tub materials:Reinforced PVC and Oxford fabric
   • Insulation:10 mm EPE
   • Filter:5-inch, 20-micron replaceable filter
   • Controls:LED touchscreen
   • Warranty:1 year
   Our verdict

   “Pick this kit over the 100-gallon bundle when extra immersion room is worth the larger footprint and water volume.”

10. AS ColdPlunge XXL Oval Inflatable Cold Plunge Tub, 148 Gal, Insulated Lid, Chiller Compatible

    

    Best Oversized Tub Without a Bundled Chiller

    View on Amazon

    This is the tub-only counterpart for buyers who want a 148-gallon oval plunge but already have, or plan to select, a chiller. Its capacity matches the AS ColdPlunge 1/3 HP Ice Bath Chiller and 148-Gallon Oval Tub Kit, but that kit includes the cooling equipment; this model leaves the chiller decision—and purchase—to you. The 7-layer construction, insulated lid, dual inlet/outlet ports, and shut-off valves are aimed at supporting circulation and temperature retention, while the pre-assembled format reduces setup steps. That large volume can suit full-body immersion and stretching, but it also takes up considerable space, especially indoors. As an inflatable tub, it is easier to move than a fixed rigid unit, yet its long-term durability under heavy use may not match a hard-shell option.

    Pros:

    • 148-gallon oval shape allows room for full-body immersion and stretching
    • Dual inlet and outlet ports support chiller circulation
    • Seven-layer construction and insulated lid support temperature retention
    • Pre-assembled setup is designed for inflation and filling

    Cons:

    • Chiller is sold separately
    • Large footprint can be difficult to accommodate indoors
    • Inflatable construction may be less durable than a hard-shell tub over extended heavy use

    Best for: Owners of a compatible chiller who want a large oval tub for full-body immersion and can give it a dedicated space.

    Not ideal for: Buyers who need a complete cooling system, have a tight indoor footprint, or prefer a rigid tub for heavy long-term use.

    • Capacity:148 gallons
    • Shape:Oval
    • Materials:Reinforced PVC, Oxford fabric, and EPE insulation
    • Construction:7-layer
    • Ports:Dual inlet and outlet ports
    • Port controls:Shut-off valves
    • Included cover:Insulated lid
    • Setup:Pre-assembled; inflate and fill
    • Usage:Indoor and outdoor
    Our verdict

    “Choose this model if you already have a chiller and want the 148-gallon oval tub without buying another cooling system.”

11. 1stplunge Ice Bath Chiller and 148-Gallon Cold Plunge Tub Kit

    

    Best Complete Oval Kit

    View on Amazon

    The 1stplunge kit is a practical choice for buyers who want a tub and chiller in one package rather than sourcing the cooling system separately. Its 148-gallon insulated oval tub offers more room than the 120-gallon AS ColdPlunge kit, while the included 1/3 HP chiller, circulation pump, filter, and hoses make it a more ready-to-connect setup. The chiller is specified to reach 42°F and run continuously, with touchscreen control for maintaining a chosen temperature. That convenience comes with limits: the tub is designed for one person, and the chiller and tub may arrive separately. Compared with the ALEKO upright tub, this is the better fit for buyers who want active chilling, but it requires more setup and relies on a powered unit.

    Pros:

    • Includes the chiller, tub, circulation pump, filter, and hoses
    • Chiller is specified to cool water to 42°F
    • 148-gallon insulated oval tub provides space for full-body immersion
    • External filter helps capture hair and debris

    Cons:

    • Tub and chiller may arrive in separate packages at different times
    • One-person capacity does not suit shared plunges
    • Requires power and assembly of the circulation connections

    Best for: Home users who want a bundled chiller system and a roomy, insulated tub for solo full-body plunges.

    Not ideal for: Buyers seeking a multi-person tub, a fully assembled upright setup, or a single delivery; the tub seats one and the components may arrive separately.

12. ALEKO 118-Gallon Cold Plunge Tub with Steps and Cover

    

    Best Assembled Upright Tub

    View on Amazon

    The ALEKO 118-gallon tub suits buyers who prefer a permanent-looking, upright plunge over an inflatable kit. It arrives fully assembled and includes red cedar steps and an insulated cover, so the basic setup is simpler than the 1stplunge kit, which includes a powered chiller but requires connecting its separate components. Its 33.5-inch diameter and 37.5-inch height create a compact footprint for a one-person tub, while the interior press-down outlet gives water a straightforward exit route. The tradeoff is that this is a tub-only option: unlike the 1stplunge or AS ColdPlunge 120-gallon kit, it does not include a chiller to actively control water temperature. Its one-person design also rules it out for shared use.

    Pros:

    • Ships fully assembled
    • Includes red cedar steps and an insulated cover
    • Interior press-down outlet simplifies draining
    • Upright form has a defined 33.5-inch diameter footprint

    Cons:

    • No chiller is included for active temperature control
    • One-person capacity limits shared use
    • Upright dimensions may feel restrictive to buyers who prefer a longer oval tub

    Best for: Buyers who want a ready-assembled upright tub with included access steps and cover, and already have a cooling plan.

    Not ideal for: People who want an all-in-one chiller bundle or a tub for two; this model includes no chiller and is designed for one person.

    • Capacity:118 gallons
    • Height:37.5 in.
    • Diameter:33.5 in.
    • Design:Freestanding, upright, one-person
    • Included components:Tub, cover, and set of stairs
    • Drain:Interior press-down outlet
    • Exterior:Charcoal with red cedar accents
    • Assembly:Fully assembled
    Our verdict

    “Pick the ALEKO if easy assembly and an upright, covered tub matter more than having a chiller included.”

13. AS ColdPlunge 1/3 HP Ice Bath Chiller and 120-Gallon Cold Plunge Tub Kit

    

    Best Starter Chiller Bundle

    View on Amazon

    This 120-gallon kit brings the key pieces together for a home plunge: a 1/3 HP chiller, tub, insulated lid, built-in circulation pump, and washable metal filter. The stated 42°F minimum and temperature-maintenance function give it an advantage over tub-only options such as the ALEKO, while its smaller capacity is easier to fit than the 148-gallon 1stplunge kit. The included inflatable step stool and quick-connect fittings also make the package more approachable for a first setup. Buyers trade some room for that more compact footprint: the round tub measures 35.4 inches across, and the chiller and tub can arrive separately. As with other powered kits, it needs a suitable place for the equipment and connections, not just floor space for the tub.

    Pros:

    • Chiller is specified to reach 42°F and maintain a selected temperature
    • Built-in circulation pump and reusable washable metal filter are included
    • Insulated lid and inflatable step stool come with the kit
    • Quick-connect fittings and hoses support home setup

    Cons:

    • Tub and chiller may arrive separately
    • 120-gallon capacity is smaller than the 148-gallon 1stplunge kit
    • Requires space and connections for a powered chiller system

    Best for: First-time home plunge buyers who want a chiller, filter, lid, and connection accessories in a smaller bundled system.

    Not ideal for: Buyers who need a very spacious tub or want all components to arrive together; its 120-gallon capacity is below the 148-gallon kits and shipments may be split.

    • Chiller power:1/3 HP
    • Tub capacity:120 gallons
    • Minimum temperature:42°F
    • Tub dimensions:35.4 in. diameter × 31.5 in. high
    • Tub materials:Reinforced fiberglass, PVC, and tear-resistant polyester
    • Included components:Chiller, tub, insulated lid, hand pump, repair kit, storage bag, hoses, and quick-connect fittings
    • Filter:Washable metal filter
    • Warranty:1 year
    Our verdict

    “Choose this bundle if you want a compact, actively chilled starter kit with useful included accessories rather than a larger tub.”

14. AS ColdPlunge XXL 216-Gallon Inflatable Ice Bath Tub with Insulated Lid

    

    Best High-Capacity Chiller-Compatible Tub

    View on Amazon

    With 216 gallons of capacity and a 59-inch length, this tub gives buyers more room for full-body immersion than the 120-gallon AS ColdPlunge kit or the 148-gallon 1stplunge bundle. Its main distinction is flexibility: 1/2-inch inlet and outlet ports connect it to most cold plunge chillers, so owners can choose a compatible cooling unit instead of buying a preset bundle. The multi-layer PVC construction, insulation, and included lid are intended to help limit heat gain, but they do not replace active chilling. Unlike the 1stplunge kit, the chiller is not included, which adds a separate purchase and compatibility decision. Its 59-inch length also calls for more room than the smaller round kits, making this a less practical choice for tight indoor spaces.

    Pros:

    • 216-gallon capacity and 59-inch length support spacious full-body immersion
    • 1/2-inch inlet and outlet ports are designed for chiller connections
    • Insulated lid and multi-layer construction help reduce heat gain
    • Includes hand pump, repair kit, and portable storage bag

    Cons:

    • Chiller is not included
    • Large dimensions require substantial floor space
    • Buyers must confirm chiller compatibility and arrange the cooling setup

    Best for: Buyers who prioritize a roomy tub and already own, or plan to select, a compatible chiller.

    Not ideal for: People seeking a compact footprint or a complete chiller bundle; this tub is large and the cooling unit must be acquired separately.

    • Capacity:216 gallons
    • Dimensions:59 × 31.5 × 25.6 inches
    • Weight:38 pounds
    • Material:PVC
    • Installation:Freestanding
    • Chiller ports:1/2-inch inlet and outlet
    • Included components:Tub, insulated lid, hand pump, repair kit, and portable storage bag
    • Chiller:Not included
    Our verdict

    “Choose this tub if capacity and chiller flexibility matter more than a compact footprint or an all-in-one purchase.”

How We Picked

I compared these 14 tubs, chillers, and bundles by how clearly each product fits a real home-plunge setup: capacity, included components, portability, and whether cooling equipment is part of the package. I also weighed practical ownership questions, including how much room a tub may take, whether the buyer must confirm compatibility, and whether a bundled kit reduces setup guesswork. Since the lineup includes both tub-only products and chiller systems, I judged each against its intended role rather than treating every listing as interchangeable.

The ranking favors complete, clearly matched setups for buyers starting from scratch, followed by products that serve a distinct need such as compact capacity, flexible placement, or an existing-tub upgrade. Larger capacity did not automatically mean a higher rank: a bigger water volume can demand more space and cooling effort. Product details provided here do not establish cooling times, temperature ranges, construction comparisons, or warranty terms, so I avoid making unsupported performance claims; buyers should confirm those specifications and connections before ordering.

Factors to Consider When Choosing Coldplunge Tubs And Chillers

Before choosing among these cold plunge tubs and chillers, decide how you plan to use the setup and what your space can support. The product names reveal useful differences in capacity and bundle contents, but the right choice also depends on installation, maintenance, and how much setup work you want to handle.

Match Tub Capacity to Your Space and Routine

Capacity is not just a comfort choice: it affects the tub’s footprint, the amount of water you manage, and the load a chiller must cool. The lineup spans 100 gallons through 216 gallons, with multiple options around 148 gallons, so buyers can compare a smaller-volume setup with a roomier middle option before moving to the largest tubs. Check the filled tub’s dimensions, access path, and placement surface rather than relying on the gallon figure alone. A tub that fits an outdoor corner when empty may be awkward to position or drain once installed. Avoid choosing the largest model by default if you will plunge alone and have limited space. Choose added capacity when multiple users or a more spacious fit matters enough to justify the added footprint and water volume.

Choose a Bundle or Build Around Equipment You Own

A bundled tub and chiller can reduce the number of separate compatibility decisions, which is useful for a first setup. A tub-only option makes more sense if you are comfortable using ice or already own cooling equipment that matches the tub. The standalone AS ColdPlunge 1/3 HP chiller is a possible route for an existing vessel, but the product name alone does not confirm connection sizes or requirements. Before mixing brands or components, verify hose fittings, pump needs, electrical requirements, and the seller’s compatibility guidance. A common mistake is buying a chiller based only on its horsepower label without checking whether it is suitable for the tub volume and conditions. If any of those details are unclear, a matched kit may save setup friction even if it limits your component choices.

Check Cooling Specifications Against Your Conditions

Chiller horsepower is only one part of cooling performance, and it does not tell you by itself how quickly a tub will reach a target temperature. Ask for the temperature range, flow requirements, operating conditions, and guidance for the specific water volume you plan to use. Outdoor heat, direct sun, and frequent lid removal can all affect how well a system maintains cold water. Larger tubs may offer more room, but they also contain more water for the chiller to handle. Do not treat two products with the same horsepower as equivalent without checking their stated capacity and operating details. If a listing does not provide these figures, get clarification before basing your choice on cooling expectations.

Plan for Placement, Power, and Water Handling

Measure the intended location, including room for access, hoses, and any step stool, before choosing a tub. Confirm that the surface can support the filled tub and that you can drain water without sending it toward a doorway, foundation, or neighboring area. A chiller adds a separate footprint and needs an appropriate power source, so a compact tub does not always mean a compact complete system. Inflatable models may offer easier storage than a fixed setup, but they still need a suitable place when filled and in use. Check the manufacturer’s setup instructions for electrical and environmental requirements rather than assuming a standard outlet or outdoor placement will work. Planning these details first can prevent a tub from becoming difficult to use even when its capacity looks right on paper.

Compare Maintenance and Water-Care Needs

Cold water still needs regular care, especially when several people use the tub or it stays filled between sessions. Find out what filtration, sanitation, and water-change routine the manufacturer recommends for the exact tub-and-chiller combination. A cover can help limit debris and exposure, but it does not replace water treatment or cleaning. Ask whether the system includes filtration or requires separate equipment, and check how the tub and plumbing are cleaned. Buyers sometimes focus on cooling hardware and overlook the recurring work of keeping water clean. If you want a low-effort routine, favor a setup with clear maintenance instructions and budget time for care before settling on a tub.

Pay for the Fit You Need, Not the Biggest Spec

Spending more can make sense when it buys a matched chiller and tub, additional room, or a setup suited to frequent use. It is less useful when the extra capacity exceeds your available space or your intended routine. Compare what each bundle actually includes: a tub, lid or cover, chiller, and any other listed accessories. The 100-gallon kits emphasize a smaller water volume, while 148-gallon kits offer a middle path and 216-gallon options prioritize capacity. For buyers who already own compatible equipment, a tub-only product or standalone chiller may avoid duplicating components. Decide which ownership problem you are paying to solve, then compare options on that basis rather than treating horsepower or gallon count as a quality score.

Frequently Asked Questions

Should I buy a tub-and-chiller bundle or a tub first?

A bundle is usually the simpler starting point if you do not already own cold-plunge equipment, since the tub and chiller are presented together. A tub-only product can make sense if you plan to use ice or already have a compatible chiller. Before buying components separately, confirm connection sizes, pump requirements, and the chiller’s stated suitability for the tub volume. Also check whether filtration or other accessories are included rather than assuming the bundle covers every part of setup. If the seller cannot confirm compatibility, choosing a matched kit reduces the risk of assembling mismatched parts.

Is a 1/3 HP chiller suitable for a 148-gallon tub?

The product lineup includes several 1/3 HP kits paired with 148-gallon tubs, but that pairing alone does not establish how quickly the water will cool or hold a target temperature. Cooling results depend on the chiller’s published capacity, starting water temperature, ambient conditions, insulation, and use patterns. Ask the manufacturer for expected performance under conditions similar to your planned placement. Check whether the kit’s pump and connections are included and designed for the listed tub. If performance details are missing, avoid relying on horsepower as the only basis for choosing.

How much space should I plan for an inflatable cold plunge?

Plan for more than the tub’s listed dimensions: allow space to enter and exit, manage hoses if using a chiller, and reach the drain. Confirm the filled footprint and placement requirements in the manufacturer’s instructions before setting it up on a deck, patio, or indoor floor. A larger inflatable model may be easier to store when deflated, but it still occupies a substantial area while filled. Check how the tub should be protected from punctures and whether the surface needs to be level. If you intend to move it often, find out how draining and drying are handled so storage remains practical.

Can I use a chiller with a tub from a different brand?

Possibly, but brand names and similar capacities do not prove that separate products will connect or operate correctly together. Compare hose fittings, water-flow requirements, pump specifications, and the chiller’s supported tub volume. Ask both manufacturers whether they support the combination, especially if the setup requires adapters or a separate pump. Unverified connections can lead to leaks, poor circulation, or a system that falls short of the expected cooling performance. If compatibility remains unclear, a bundled kit is the safer route for a first-time setup.

Do I need a chiller if I am willing to use ice?

Not necessarily: a tub-only model can suit someone who is comfortable adding ice and does not need the same level of automated temperature control. That approach means planning for ice supply and repeated manual adjustment, and the routine may become inconvenient with frequent use. A chiller adds equipment, power needs, and setup considerations, but it is designed to cool or maintain water without relying solely on added ice. Compare the effort you are willing to spend with the cooling consistency you want. Before deciding, check whether your preferred tub is compatible with a chiller should you want to add one later.

Conclusion

My best overall recommendation is the AS ColdPlunge 1/3 HP Ice Bath Chiller and 148-Gallon Tub Kit for buyers who want a matched setup at a middle capacity. For a smaller-volume system, compare the 100-gallon chiller kits; for a larger, roomier option, the 216-gallon bundle is the premium-capacity direction, provided you can support its footprint and cooling needs. Beginners should favor a bundled kit over assembling a tub and chiller separately, while buyers who already own compatible equipment can look at the standalone AS ColdPlunge chiller or a tub-only option. If portability and storage matter most, consider an inflatable model, but verify its chiller connections and care requirements. My final choice would come down to available space, included components, and confirmed cooling specifications—not capacity or horsepower alone.
