For a premium two-person cold plunge tub with chiller, my best overall pick is the Smartmak 500-gallon system, which pairs a red cedar tub with heating and cooling, Wi-Fi, and multiple water-treatment features. The AS ColdPlunge 1HP 216-gallon bundle is a strong alternative for buyers prioritizing a large insulated tub and external pump, while the 90-gallon Luxury Pro-Grade model may suit shoppers who prefer a smaller footprint. The main tradeoffs are tub capacity and shared comfort versus cooling power, included filtration, installation needs, and space. Many listings in this roundup specify 148 gallons, so buyers seeking comfortable two-person use should check interior dimensions rather than rely on a capacity label alone. Read on for the full breakdown and guidance on choosing a setup that fits your home and routine.

Key Takeaways
- Smartmak leads on premium features: It is the only listed option described with red cedar construction, a stainless steel base, hot-and-cold operation, Wi-Fi, filtration, ozone, and UV treatment.
- The 1HP, 216-gallon kits stand apart on capacity and chiller rating: The AS ColdPlunge bundle and the similar oval kit are the clearest choices for shoppers comparing larger tubs with stronger listed chiller power.
- Most of the lineup is built around 148-gallon kits: Several listings share that capacity and 1/3 HP cooling, so the tub dimensions, pump arrangement, and included support matter more than the headline wording.
- Cooling claims vary across smart-control models: Icegalax listings cite 34°F or 38°F cooling, while Deeptime lists 38°F; compare stated targets with your intended use and local operating conditions.
- Two-person suitability is not proven by capacity alone: The 90-gallon model and 400-gallon Frozin name suggest different sizing approaches, but the provided listing details do not establish usable interior space or a shared-use layout.

More Details on Our Top Picks
Smartmak 500 Gal Cold Plunge Tub with 1HP Chiller, Red Cedar Ice Bath Tub, Cold and Hot System, Stainless Steel Base, WiFi, Filter, Ozone, UV (37-107 ℉)
The Smartmak is the standout for buyers who want a substantial, permanent-looking plunge rather than a portable-style tub. Its 500-gallon capacity and 51-by-36-inch footprint offer more room than the AS ColdPlunge 216-gallon bundle, while red cedar and a stainless steel base give it a more furniture-like presence. The WiFi chiller covers both cold and warm water settings, and UV plus ozone treatment adds water-care equipment in the package. That scale comes with real demands: the tub is heavy, installation and upkeep need planning, and the supplied details do not clarify how comfortably two adults can plunge at once. Unlike the smaller 90-Gallon Luxury Pro-Grade, this is a better fit for a dedicated installation than a compact, easier-to-place setup.
Pros:- 500-gallon capacity provides substantially more water volume than the 216-gallon AS ColdPlunge bundle.
- Red cedar and stainless steel construction suit a permanent, premium-looking setup.
- WiFi control and a 37–107°F range support app-managed cold and warm sessions.
- UV and ozone systems provide included water-treatment features.
Cons:- Large capacity and heavy construction make delivery, installation, and relocation more demanding.
- Requires ongoing installation and maintenance rather than a minimal-setup plunge.
- The product details do not specify a two-person capacity or the chiller’s cooling performance under particular conditions.
Best for: Buyers with a dedicated indoor or outdoor installation area who prioritize cedar construction, large water capacity, and app-controlled hot-and-cold operation.
Not ideal for: Renters, frequent movers, or buyers who need a clearly documented two-adult fit and a tub that is simple to relocate.
- Water capacity:500 gallons
- Dimensions:51 × 36 × 28 inches
- Materials:Red cedar and stainless steel
- Cooling power:2405W
- Heating power:3600W
- Temperature range:37–107°F
- Water treatment:UV and ozone
- Certification:ETL
Our verdict“Choose the Smartmak if you have room for a substantial cedar tub and value its large capacity and hot-and-cold WiFi system over easier placement.”
AS ColdPlunge 1HP Ice Bath Chiller & Cold Plunge Tub Bundle, 216 Gallon Insulated Tub with External Pump & Filtration
The AS ColdPlunge bundle makes the most sense for buyers who want a roomy, insulated tub with the circulation equipment included. Its 216-gallon capacity is smaller than the Smartmak’s 500 gallons, but the reinforced-PVC design and thick insulation are more practical for buyers who want a plunge setup rather than a cedar centerpiece. A 1HP chiller, external pump, filter, insulated lid, and hoses arrive as a coordinated kit, and the system is specified to reach 37°F. That package can reduce guesswork, though installation still takes planning and the one-year warranty is a limited coverage window. Compared with the AS ColdPlunge 148-gallon, 1/3 HP kit, this model offers more capacity and a more powerful chiller, but asks for more space and setup effort.
Pros:- 216-gallon capacity offers more room than the brand’s 148-gallon 1/3 HP kit.
- 1HP chiller is specified to cool water to 37°F without relying on ice.
- Insulation and an included lid support temperature retention between sessions.
- Bundle includes pump, filtration, hoses, repair kit, hand pump, and storage bag.
Cons:- Reinforced PVC does not provide the rigid, furniture-like finish of the Smartmak’s cedar and steel construction.
- Requires substantial setup space and may need installation help.
- Warranty coverage is listed as one year.
Best for: Home athletes or recovery-focused households who want a large insulated plunge with a 1HP chiller, pump, and filtration included.
Not ideal for: Buyers with limited floor space, those seeking a rigid premium-finish tub, or anyone who wants a straightforward, quick setup.
- Model:AS1000-XXL216
- Water capacity:216 gallons
- Chiller power:1 HP
- Temperature:Down to 37°F (2.7°C)
- Material:Reinforced PVC
- Insulation:Thick insulation layers
- Included components:Chiller, pump, filter, hoses, insulated lid, hand pump, repair kit, storage bag
- Warranty:1 year
Our verdict“Pick this bundle if you want a large, insulated, equipment-complete plunge and can accommodate its setup footprint.”
Icegalax Ice Bath Tub with Water Chiller, 34℉ Cooling, Smart Control
Icegalax is the pick for buyers whose priority is a particularly low stated water temperature, not a compact footprint. The listing specifies cooling to 32°F and supports users up to 6 feet 9 inches, making it a strong fit for taller athletes seeking full-body immersion. Its 76.77-inch length is considerably greater than the 90-Gallon Luxury Pro-Grade tub’s 36-inch length, so placement matters; the tradeoff is a longer interior for stretching out. Smart control, dual filtration, ozone sanitation, and a thermal cover give the setup more water-care and temperature-management features than the simpler description of the AS ColdPlunge 148-gallon kit. The supplied information does not identify capacity or tub material, however, so I would verify fit, construction, and installation requirements before choosing it for two-person use.
Pros:- Listed cooling temperature of 32°F is lower than the 37°F specification on the AS ColdPlunge 216-gallon bundle.
- Maximum user height of 6 feet 9 inches supports taller users seeking full-body immersion.
- Dual filtration, ozone sanitation, and a thermal cover are included.
- Smart temperature control and stated 65dB operation add control and noise information.
Cons:- At 76.77 inches long, it requires substantial placement space.
- Water capacity and tub material are not specified in the supplied product data.
- Setup may be challenging, and the available details do not confirm two-adult capacity.
Best for: Taller athletes and recovery-focused buyers who have room for a long freestanding tub and prioritize a low stated temperature.
Not ideal for: Small-space households or buyers who need confirmed water capacity, material details, or explicit two-adult dimensions before purchasing.
- Temperature:Down to 32°F
- Dimensions:76.77 inches long × 31.5 inches wide
- Maximum user height:6 feet 9 inches (206 cm)
- Noise level:65dB
- Control:Smart temperature control
- Water treatment:Dual filtration and ozone sanitation
- Included components:Water chiller, phone holder, replacement filters, thermal cover
Our verdict“Choose the Icegalax if very low stated temperatures and room for a long tub matter more than documented capacity and compact placement.”
AS ColdPlunge Ice Bath Chiller & Cold Plunge Tub Kit, 1/3 HP with Built-in Pump & Filter, 148 Gallon XXL Ice Pod for Cold Therapy Recovery
This AS ColdPlunge kit suits buyers who want the pump and filter integrated with the chiller rather than selecting separate circulation equipment. The 148-gallon oval tub is a step down in capacity from the brand’s 216-gallon 1HP bundle, but its included insulated lid, hoses, repair kit, and storage bag make it a complete home setup. A 1/3 HP chiller reaches 42°F, which is a warmer floor than the 37°F offered by the larger bundle and the Smartmak; that distinction matters to buyers who want colder water. Reinforced PVC, Oxford fabric, and EPE insulation support a portable-style construction, though assembly and bulky handling remain part of the job. This is the more contained equipment package, not the choice for maximum capacity or the lowest temperature.
Pros:- Built-in pump and filter simplify the equipment arrangement compared with the external-pump 216-gallon bundle.
- 148-gallon capacity offers a substantial tub without the Smartmak’s 500-gallon scale.
- Insulated lid and EPE insulation support temperature management between sessions.
- Kit includes hoses, fittings, repair kit, and storage bag.
Cons:- The 42°F minimum is warmer than the 37°F specifications on the Smartmak and 216-gallon AS bundle.
- Assembly takes time, and the bulky kit can be difficult to move.
- The one-year warranty is limited in duration.
Best for: Home users who want a complete 148-gallon kit with a built-in pump and filter and are comfortable with a 42°F minimum.
Not ideal for: Buyers seeking temperatures below 42°F, maximum immersion space, or a rigid cedar-and-steel tub.
- Capacity:148 gallons
- Chiller power:1/3 HP
- Temperature:Down to 42°F
- Materials:Reinforced PVC, Oxford fabric, and EPE insulation
- Pump and filtration:Built-in pump and filter
- Included components:Chiller, tub, insulated lid, pump, filter, hoses, fittings, repair kit, storage bag
- Warranty:1 year
Our verdict“Choose this kit if an integrated pump-and-filter setup and moderate capacity matter more than a colder temperature or larger tub.”
90-Gallon Luxury Pro-Grade Cold Plunge Tub with 1050W Water Chiller
The 90-Gallon Luxury Pro-Grade is the most space-conscious option here, pairing a compact 36-by-36-inch footprint with a 1050W chiller, WiFi control, and built-in filtration. It reaches 37°F without ice, matching the stated minimum of the larger AS ColdPlunge 216-gallon bundle while using far less water. That makes it easier to place than the 148- and 216-gallon tubs, but the smaller capacity and 6-foot-5-inch user limit make it a less convincing choice for two adults sharing a plunge. Military-grade drop-stitch construction and weatherproof design support indoor or outdoor placement, though the first cooldown can take up to 10 hours. Compared with the cedar Smartmak, this is less of a permanent centerpiece and more of a compact, feature-equipped recovery station.
Pros:- 36-by-36-inch dimensions are more space-conscious than the long Icegalax tub.
- 1050W chiller reaches 37°F without ice.
- WiFi control and built-in filtration are included.
- Military-grade drop-stitch fabric and weatherproof design support indoor or outdoor use.
Cons:- 90-gallon capacity is modest beside the 148-, 216-, and 500-gallon options.
- Initial cooldown can take up to 10 hours.
- Listed user-height limit is 6 feet 5 inches, and the compact size does not establish comfortable two-person fit.
Best for: Solo users who need a compact indoor or outdoor setup with WiFi temperature control and included filtration.
Not ideal for: Two adults expecting roomy shared immersion, users taller than 6 feet 5 inches, or buyers who need rapid initial cooldown.
- Capacity:90 gallons
- Dimensions:36 × 36 × 32 inches
- Cooling capacity:1050W
- Minimum temperature:37°F
- Material:Military-grade drop-stitch fabric
- User height limit:6 feet 5 inches
- Control:WiFi control
- Filtration:Built-in filtration system
Our verdict“Pick this model for a compact, feature-equipped solo plunge, but choose a larger tub if two-person room is the priority.”
1HP Ice Bath Chiller & Cold Plunge Tub Kit, 216 Gallon Oval Cold Plunge Tub with External Pump & Filter
For buyers who want generous room for two, this 216-gallon oval tub has the clearest capacity advantage in this group. Its 1HP chiller reaches 37°F, giving it more cooling power and a lower stated temperature than the 1/3 HP, 148-gallon kits from 1stplunge and Product 7. That makes this the stronger fit for a roomy, very cold setup, though the available information does not establish how quickly it reaches that temperature under particular conditions. The reinforced PVC, Oxford fabric, and foam construction keep the kit portable rather than rigid, and included caster wheels help with positioning. The tradeoff is more involved setup: the tub and chiller may arrive separately, and the filter is recommended for replacement every two weeks. I’d choose it for capacity and cooling range, not minimal upkeep.
Pros:- 216-gallon oval capacity offers more room than the 148-gallon kits in this group.
- 1HP chiller has a stated minimum temperature of 37°F.
- External pump and 20-micron filter support water circulation and filtration.
- Inflatable cover and caster wheels are included for covering and moving the setup.
Cons:- Tub and chiller may arrive in separate shipments.
- Assembly requires some setup knowledge.
- Filter replacement is recommended every two weeks.
Best for: Households seeking a roomy, portable two-person-style plunge with a 1HP chiller and a stated cooling floor of 37°F.
Not ideal for: Buyers who want a rigid permanent tub, minimal assembly, or infrequent filter changes.
- Chiller power:1HP
- Water capacity:216 gallons
- Stated minimum temperature:37°F
- Tub material:Reinforced PVC, Oxford fabric, and EPE foam
- Filter:20-micron external filter
- Included components:Pump, filter, hoses, fittings, inflatable cover, and caster wheels
- Warranty:1 year
Our verdict“Choose this kit if two-person-oriented capacity and a 37°F-capable 1HP chiller matter more than simple setup and low filter upkeep.”
1/3 HP Ice Bath Chiller & 148 Gal Cold Plunge Tub Kit for Home Cold Therapy
This 148-gallon kit is the most clearly app-oriented option in the lineup: it pairs a WiFi-controlled chiller with a large touchscreen, so temperature adjustments need not happen only at the unit. Its stated floor of 42°F without ice suits buyers who want automated cooling but do not need the 37°F target offered by the 1HP, 216-gallon kit. The 10 mm tub insulation is a useful detail for home use, where holding temperature can matter between sessions. Compared with Product 8, which also offers WiFi and a 148-gallon tub, this listing specifies the insulation thickness and includes a repair kit and carry bag. The tradeoffs are the smaller chiller and separate-package delivery; assembly is still part of the job. I’d favor it for connected controls and a clearly defined accessory set, rather than maximum cold or capacity.
Pros:- WiFi app and touchscreen provide two ways to adjust settings.
- 148-gallon insulated oval tub is designed for full-body immersion.
- External pump, filter, hoses, repair kit, and carry bag are included.
- Chiller is stated to cool to 42°F without ice.
Cons:- The 1/3 HP chiller has a higher stated minimum temperature than the 1HP, 216-gallon kit.
- Separate packages may arrive at different times.
- Assembly is required.
Best for: Home users who want remote temperature adjustments, a touchscreen, and a complete 148-gallon kit for regular recovery sessions.
Not ideal for: Buyers targeting temperatures below 42°F or those who want a larger tub and more powerful chiller.
- Chiller power:1/3 HP
- Water capacity:148 gallons
- Stated minimum temperature:42°F
- Controls:WiFi app and touchscreen
- Tub insulation:10 mm
- Pump and filtration:External pump with filter
- Included accessories:Hoses, filter, repair kit, and carry bag
- Warranty:1 year
Our verdict“Pick this kit for connected controls and a complete home setup, but choose a 1HP option if you want a stated 37°F target.”
Cold Plunge Chiller with 148-Gallon Ice Bath Tub Kit for Cold Therapy
The most distinguishing claim here is 40 dB operation, which gives this 148-gallon kit a specific advantage for buyers placing a chiller near a living area or recovery room. It shares the 1/3 HP power and 42°F target of Product 7, so I would not rank it above that kit for cooling range. Its alternative case is the stated seven-layer reinforced insulation and a replaceable 20-micron cartridge, details that help buyers understand the tub’s construction and filtration approach. WiFi control and a top-mounted HD display add convenience, while the external pump and filter make this a complete system rather than a tub that needs separate components. Compared with the Frozin 400, this kit offers more capacity but uses a flexible insulated tub rather than roto-molded construction. Separate deliveries and setup complexity remain real drawbacks.
Pros:- Stated 40 dB operation suits buyers attentive to chiller noise.
- 148-gallon tub is larger than the Frozin 400’s 100-gallon capacity.
- WiFi control and a top-mounted HD touch display offer convenient adjustments.
- Seven-layer reinforced insulation and a replaceable 20-micron filter are specified.
Cons:- The 1/3 HP chiller is specified to cool to 42°F, not the 37°F stated for the 1HP kits.
- The tub and chiller ship in separate packages.
- Setup may be complex for some buyers.
Best for: Buyers setting up a 148-gallon plunge in a home or recovery space where quieter stated operation and connected controls are priorities.
Not ideal for: Those who need a 37°F target, prefer a rigid roto-molded tub, or want to avoid assembly and separate deliveries.
- Chiller power:1/3 HP
- Tub capacity:148 gallons
- Stated minimum temperature:42°F
- Operation noise:40 dB
- WiFi compatibility:2.4 GHz
- Filter:20-micron replaceable cartridge
- Insulation:7-layer reinforced insulation
- Warranty:1 year
Our verdict“Choose this model for its stated quiet operation and connected 148-gallon setup, not for the coldest target or a rigid tub.”
Frozin 400 Cold Plunge Tub with Water Chiller
Unlike the flexible insulated tubs elsewhere in this batch, the Frozin 400 uses roto-molded construction with full foam insulation. That makes it the most appealing pick here for buyers who prefer a more substantial tub build over a portable kit. Its 0.8 HP chiller is stated to reach 37°F, closer to the cooling target of the 1HP, 216-gallon kit than the 42°F target on the 148-gallon models. The capacity is 100 gallons, however, so it gives up substantial room to those larger oval tubs; the product data does not establish it as a comfortable two-person option. A 650 GPH pump and filtration are included, and the listing states it is made in the USA. The tradeoffs are its smaller capacity, a need for dedicated space and power, and the potential energy demands of sustained chilling.
Pros:- Roto-molded construction offers a rigid alternative to the flexible tubs in this batch.
- Full foam insulation is specified for retaining cold water.
- 0.8 HP chiller has a stated water temperature of 37°F.
- Includes a 650 GPH pump flow rate and water filtration.
Cons:- 100-gallon capacity is lower than the 148- and 216-gallon kits.
- The listed 48 x 28 x 28-inch dimensions require a dedicated setup area.
- Chiller operation requires power and may bring higher energy use.
Best for: Buyers who prioritize a rigid roto-molded, foam-insulated plunge and a stated 37°F target over two-person capacity.
Not ideal for: Two-person households seeking generous shared space, or buyers who need a flexible, easy-to-relocate setup.
- Capacity:100 gallons
- Dimensions:48 x 28 x 28 inches
- Chiller power:0.8 HP
- Stated water temperature:37°F
- Pump flow rate:650 GPH
- Insulation:Fully foam insulated
- Tub material:Roto-molded
- Manufacturing origin:USA
Our verdict“Choose the Frozin 400 for rigid construction and a 37°F target, but skip it if two-person room is your main requirement.”
Ice Bath Chiller & 148-Gallon Cold Plunge Tub Kit for Cold Recovery Therapy
This 1stplunge kit is a practical pick for buyers who want a 148-gallon tub, 1/3 HP chiller, pump, and filter in one system without app control being a stated feature. Its touchscreen controller handles temperature adjustments, and the chiller is specified to reach 42°F. Compared with Product 7, it offers a similar capacity and cooling target but lists a 110-volt supply and a notably compact chiller unit footprint; that can help with planning a home installation, though it does not make the tub itself compact. The product data calls the seating capacity one, so I would not treat the 148-gallon figure alone as proof of comfortable two-person use. Separate shipping and setup complexity also temper the “all-in-one” convenience. For a lower target or more explicit connected controls, Product 7 or the 1HP, 216-gallon kit is a better match.
Pros:- Kit includes the chiller, tub, external filter, circulation pump, and accessories.
- Touchscreen controller provides direct temperature adjustment.
- Chiller is specified to cool water to 42°F.
- 110-volt power specification supports planning for a home setup.
Cons:- The listed seating capacity is one, so two-person use is not established by the product data.
- Chiller and tub may arrive in separate shipments.
- Setup may be complex for some buyers.
Best for: Home recovery users who want a 148-gallon kit with touchscreen temperature control and a listed 110-volt connection.
Not ideal for: Buyers who specifically want WiFi or app control, a stated 37°F target, or verified two-person seating.
- Model name:Ice Bath Chiller and Ice Bath Tub
- Manufacturer:1stplunge
- Water temperature:42°F
- Capacity:148 gallons
- Seating capacity:1
- Voltage:110 volts
- Chiller dimensions:12.6 x 11.4 x 11.4 inches
- Warranty:1-year limited warranty
Our verdict“Choose this kit for a touchscreen-controlled, 148-gallon home plunge, but look elsewhere if you need app control or a confirmed two-person layout.”
ColdPlunge 1/3 HP Ice Bath Chiller & 148 Gallon Cold Plunge Tub Kit
This kit is a practical fit for buyers who want a 148-gallon insulated tub and the main circulation pieces in one bundle. Its 1/3 HP chiller is specified to cool water to 42°F, while the external pump and filter help keep water moving and reduce the need to add ice. Compared with the WiFi-controlled 148-gallon kit in this roundup, this model has no stated app control, but it does list useful setup accessories including shut-off valves, a repair kit, and a carry bag. The 10 mm EPE insulation can help limit temperature loss between sessions. The tradeoffs are a one-year warranty, some hands-on setup, and the possibility that the chiller and tub arrive separately, making this less convenient for anyone expecting a single-box installation.
Pros:- 148-gallon oval tub offers ample capacity for a roomy plunge.
- 1/3 HP chiller is specified to reach 42°F without relying on ice.
- Pump, filter, hoses, shut-off valves, repair kit, and carry bag are included.
- 10 mm EPE insulation helps retain cold between sessions.
Cons:- Chiller and tub may ship separately and arrive at different times.
- External components require more setup than the integrated ICEGALAX unit.
- One-year warranty is limited for a substantial home system.
Best for: Home recovery users who want a large insulated tub with pump, filtration, and setup accessories included.
Not ideal for: Buyers who want app-based control, a longer stated warranty, or a plug-and-play unit with no separate equipment setup.
- Model number:ASDY300-XL148
- Capacity:148 gallons
- Chiller power:1/3 HP
- Cooling temperature:42°F
- Tub material:Reinforced PVC and Oxford fabric
- Insulation:10 mm EPE
- Included components:Chiller, tub, pump, filter, hoses, shut-off valves, repair kit, carry bag
- Warranty:1 year
Our verdict“Choose this kit if you want a large, insulated 148-gallon setup with core accessories and can handle some assembly.”
ICEGALAX Cold Plunge Tub with Water Chiller, 38°F Cooling, Smart Control
The ICEGALAX is the clearest pick here for buyers who would rather use an integrated tub, chiller, and filtration system than assemble a kit of separate parts. Its stated minimum of 38°F is colder than the 42°F target listed for both 148-gallon ColdPlunge kits, and app control adds remote monitoring and adjustment. At 77 inches long, it is designed to accommodate users up to 6’9″, though its 300-liter capacity is much smaller than the 148-gallon tubs in this roundup. That makes it a more streamlined full-body option, not the choice for two adults to plunge together. The package lists a thermal cover and three filters, but replacement filters mean ongoing upkeep. Its 140-pound weight and broad footprint also call for a planned installation spot rather than a compact corner.
Pros:- Integrated cooling and filtration simplify setup compared with external-chiller kits.
- App control supports remote temperature monitoring and adjustment.
- 38°F stated cooling target is colder than the 42°F ColdPlunge kits.
- 77-inch length and stated fit for users up to 6’9″ support full-body plunges.
Cons:- 300-liter capacity is far below the 148-gallon tubs and is not a strong fit for two-person use.
- Large 77-by-32-inch footprint can be difficult to place in a small room.
- Regular filter replacement adds ongoing maintenance.
Best for: Tall solo plungers who want an integrated, app-controlled system and have room for a full-length tub.
Not ideal for: Two-person households seeking a genuinely shared-capacity tub, or buyers with tight indoor space.
- Model number:IGT-V3-Basic
- Capacity:300 liters
- Temperature:As low as 38°F (3°C)
- Dimensions:77″ L x 32″ W x 28″ H
- Weight:140 pounds
- Material:Plastic
- Included components:Tub, phone holder, thermal cover, 3 filters, rubber ducks
- Control:Smart app control
Our verdict“Pick the ICEGALAX for convenient, app-controlled solo plunges, but choose a larger kit if shared use is the priority.”
1/3 HP Ice Bath Chiller & 148 Gal Oval Cold Plunge Tub Kit for Cold Therapy
This 148-gallon kit suits buyers who want the familiar capacity of a soft-sided plunge but also value WiFi app control and a touchscreen. Its 1/3 HP chiller is specified to cool water to 42°F, matching the target of the other ColdPlunge kit, while the included pump and washable filter form a complete circulation setup. The insulated tub and lid help reduce heat gain between sessions; compared with the ICEGALAX, however, this is a separate-component kit rather than an integrated appliance, so setup takes more work and it needs space for the chiller and connections. The app offers remote operation, but buyers who prefer simple manual controls may find the added interface unnecessary. Separate shipping for the tub and chiller can also delay a complete setup.
Pros:- 148-gallon capacity offers more room than the 300-liter ICEGALAX tub.
- WiFi app and touchscreen provide remote and on-unit control.
- Pump, washable filter, hoses, and fittings are included.
- EPE insulation and a lid help limit heat gain between plunges.
Cons:- Requires assembly and connection of separate chiller and tub components.
- Tub and chiller may ship separately, delaying installation.
- 42°F stated cooling target is warmer than the ICEGALAX and Deeptime 38°F targets.
Best for: Cold-plunge users who want 148-gallon capacity, an insulated lid, and remote control through a phone or touchscreen.
Not ideal for: Buyers who want a compact, single-piece unit or do not want to manage WiFi setup and separate equipment.
- Chiller power:1/3 HP
- Water capacity:148 gallons
- Temperature range:Cools water to 42°F
- Control:WiFi app and touchscreen
- Insulation:EPE insulation with lid
- Included components:Chiller, tub, hoses, fittings, pump, filter, repair kit, carry bag
Our verdict“Choose this kit if remote control and a large insulated tub matter more than integrated, low-effort installation.”
Deeptime Smart Ice Bath Tub with Chiller, App Control, 38°F Cold Plunge
Deeptime takes a different approach from the two 148-gallon fabric kits: its acrylic-and-metal construction and self-contained cooling system give it a more permanent-appliance profile. The stated 38°F minimum matches the ICEGALAX, and app control supports remote adjustment and monitoring. Its 80-gallon capacity, though, is substantially below the 148-gallon ColdPlunge options, so despite the roomy exterior dimensions, I would treat it as a generous solo plunge rather than a tub for two adults to use together. At 395 pounds, it is also much heavier than the 140-pound ICEGALAX; that weight may suit a stable installation but complicates delivery, placement, and moving it later. The product data does not list a warranty or included accessories, so buyers should confirm those details before choosing it over a more fully itemized kit.
Pros:- Acrylic-and-metal construction offers a more rigid format than the fabric 148-gallon kits.
- Integrated cooling system avoids the separate-chiller arrangement of the ColdPlunge kits.
- 38°F stated minimum supports colder settings than the 42°F ColdPlunge options.
- App control enables remote temperature adjustment and monitoring.
Cons:- 80-gallon capacity is smaller than the 148-gallon kits and limits its fit for shared plunges.
- 395-pound weight makes delivery and placement more demanding than the ICEGALAX.
- Warranty and included accessories are not specified in the supplied product data.
Best for: Buyers seeking a rigid, self-contained cold plunge for a permanent home or gym installation, with app control and a 38°F target.
Not ideal for: Two-person users, renters, or anyone who may need to move the tub or install it in a small or structurally unsuitable room.

How We Picked
I ranked these options by how well their stated features support the specific goal of a premium two-person setup: useful interior space, chiller capacity, tub insulation, water circulation and filtration, controls, and the scope of the included kit. I gave more weight to listings that describe both the tub and chiller together, since a compatible bundle can simplify planning, but I treated marketing names and gallon figures as starting points rather than proof of comfortable two-person fit.
The order reflects the evidence available in the product descriptions, not hands-on testing. The Smartmak ranks first for its unusually complete stated feature set; the 1HP, 216-gallon kits follow for their combination of capacity and chiller power. Options with 1/3 HP chillers and 148-gallon tubs remain useful for buyers prioritizing a more modest setup, while models with limited or overlapping details rank lower because buyers have less information to judge fit and maintenance. I would verify dimensions, electrical requirements, operating limits, warranty, and what is actually included before choosing any listing.
Factors to Consider When Choosing Premium Two Person Cold Plunge Tub With Chiller
A headline capacity or chiller rating cannot settle whether a tub will work for your household. I would compare the installation conditions and day-to-day routine alongside the product specifications, particularly when two people may use the tub together.
Check the Interior Layout, Not Just Gallons
Capacity tells you how much water a tub may hold, not how two adults will fit inside it. Ask for interior length, width, depth, and usable seating or lounging dimensions, then compare them with the tallest intended user. A rounded or oval footprint can use the same volume differently from a long, narrow tub. Also check whether the advertised capacity includes water filled near the rim, since normal fill levels may be lower. If you plan to plunge together, prioritize shoulder room and entry clearance over a larger number in the product name. When dimensions are missing, treat the two-person claim as unverified and request them before ordering.
Match Chiller Power to Your Water Volume and Climate
A 1HP chiller is a stronger listed specification than a 1/3 HP unit, but it does not tell the whole performance story. Cooling speed also depends on tub volume, insulation, starting water temperature, sunlight, and how often the lid is removed. Ask the seller for expected cooling time at your target temperature and the conditions used to calculate it. A larger tub can take longer to cool even with a more powerful unit, while a well-insulated smaller tub may hold temperature with less work. Avoid choosing on the lowest stated temperature alone; ongoing heat gain and recovery time may matter more to regular use. Match the chiller to your local climate and planned frequency, not just the most eye-catching rating.
Plan the Site, Power, and Water Handling
Before ordering, measure the route into the installation area as well as the final footprint. A filled tub is extremely heavy, so the supporting surface must be rated for the combined weight of the tub, water, and occupants. Confirm the chiller’s electrical requirements, whether it needs a dedicated circuit, and how much clearance it needs for ventilation and service access. External pumps and chillers can simplify tub access but take up additional floor space and require hose routing. Think through how you will drain the water without sending it toward a foundation, walkway, or neighboring property. A setup that fits on paper can still be impractical if filling, draining, or servicing it is awkward.
Compare Filtration and Water-Care Responsibilities
Filters, ozone, and UV are different parts of a water-care system, not a reason to assume maintenance is automatic. Check what filter type the kit uses, how often it needs cleaning or replacement, and whether replacements are easy to source. Ask whether ozone or UV is included in the exact package and what water testing or treatment the manufacturer still recommends. A two-person tub can accumulate contaminants faster than a single-user setup, especially if multiple people use it regularly. Set a realistic routine for testing, cleaning, and water changes before purchase. A simpler system may be a better fit if you do not want to manage several treatment components.
Decide Which Premium Extras You Will Actually Use
Premium construction and smart features matter most when they solve a real need. Cedar, a reinforced base, app controls, or heating may improve the appearance, control, or year-round flexibility of a setup, but each can add complexity and upkeep. Make a short list of must-haves, such as remote temperature control or warm-water capability, before comparing bundles. If you only want cold immersion, a less elaborate kit with a clearly specified chiller and filtration system may be easier to maintain. Confirm whether app features work over your home’s network and whether the controls remain usable without an app. Pay extra for features you expect to use, rather than treating a longer feature list as proof of better fit.
Verify What the Bundle Includes and What Support Covers
Product titles can make a package sound complete while leaving important components unclear. Confirm that the tub, chiller, pump, hoses, filter, cover, fittings, and any treatment hardware are included in the exact configuration you are buying. Check whether the unit arrives assembled, how much setup is required, and whether installation support is available. Warranty coverage may differ between the tub, chiller, and electronic parts, so review each term rather than relying on a single headline. Ask how service and replacement parts are handled if the chiller or pump stops working. Clear bundle details can matter more to long-term ownership than a small difference in stated capacity.
Frequently Asked Questions
Can I assume a tub labeled for two people will comfortably fit two adults?
No. A two-person label or large gallon figure does not confirm usable shoulder room, seating shape, or entry space. Request the interior dimensions and compare them with the users’ heights and preferred posture. If the listing does not provide those measurements, ask for a dimensioned diagram before buying. For shared plunges, the usable footprint matters more than the maximum water capacity.
Is a 1HP chiller automatically the better choice than a 1/3 HP chiller?
Not automatically. A 1HP rating may be better suited to a larger water volume or faster recovery, but actual results also depend on insulation, ambient temperature, and how often the tub is opened. A smaller chiller may be adequate for a modest tub used under favorable conditions. Ask for expected cooling and recovery times for the specific tub bundle rather than comparing horsepower alone. Also check electrical requirements and operating guidance before choosing the larger unit.
Which details should I confirm before ordering a tub and chiller bundle?
Confirm the tub’s interior dimensions, chiller capacity, electrical requirements, and the components included in the exact package. Ask whether the pump, filtration, hoses, cover, and fittings are supplied, since titles do not always make bundle contents clear. Check the setup footprint, ventilation clearance, drainage plan, and weight of the filled tub. Review warranty coverage for the tub and chiller separately. These checks can prevent a mismatch between the product listing and your installation space or maintenance expectations.
Do ozone or UV features mean I can skip water testing and cleaning?
No. Ozone and UV can be parts of a treatment system, but they do not mean the water needs no monitoring or upkeep. Follow the manufacturer’s instructions for testing, filtration, cleaning, and water replacement. Ask which components are included in the package and whether they require routine servicing. With multiple users, a consistent care routine is especially important. If you want low-maintenance ownership, compare the full care schedule rather than focusing on one treatment feature.
Is a lower stated temperature always better for a cold plunge?
Not necessarily. A lower target can offer more range, but a buyer should also consider temperature stability, cooling time, climate, and the intended routine. Listings in this roundup cite different targets, and those claims may not reflect identical testing conditions. Choose a unit with controls that make it practical to set and monitor your preferred temperature. Check the manufacturer’s guidance for safe use and avoid treating the lowest advertised figure as a measure of overall quality.
Conclusion
For the best overall feature set, I would start with the Smartmak 500-gallon system, while verifying its dimensions and installation needs before purchase. The best value direction is one of the 148-gallon 1/3 HP kits if a more modest capacity and cooling setup meet your plans; compare the included pump, filter, and support rather than choosing by title. For a premium upgrade, Smartmak is the clearest match in this lineup thanks to its cedar construction, hot-and-cold capability, and stated water-treatment features. Beginners may prefer a clearly documented bundle with straightforward controls and accessible maintenance details over a more complex smart system. For buyers who need a larger tub and stronger listed chiller, compare the AS ColdPlunge 1HP 216-gallon bundle with the similar oval kit, then confirm their interior measurements. The right choice depends on verified fit, site readiness, and the maintenance routine you are willing to keep.
