If you want to turn your bathing routine into a cold plunge, you can use a suitable existing bathtub with cold water and ice—or choose a separate tub designed for repeated cold-water sessions. The products below are standalone tubs, not retrofit kits for a built-in bathtub. The CRYDIP is the closest match for someone who wants one portable tub for both warm baths and cold plunges, while the other picks focus more on dedicated immersion, compact storage, or a space-saving shape.
Before buying, measure your space, check how you’ll drain and refill the tub, and consider whether you want to add ice by hand or connect a compatible chiller. A chiller is not included with these options.

Ice Cap Cold Plunge Tub: A Compact, Rigid Upright Plunge
The Ice Cap takes a different approach from a standard soaking tub: it is tall and narrow, with a 29-inch diameter and a 40-inch height. That upright shape can make a dedicated plunge more practical in a garage, patio, or other area where a long tub would be hard to fit. The brand says it accommodates users up to 6 feet 6 inches and 300 pounds.
Its rigid, rotomolded body is made from food-safe resin, according to the product description. A molded step doubles as an internal seat, while built-in drain ports are intended to make water changes easier. The tub can be used with ice alone or connected to a compatible chiller through its 3/4-inch ports; a chiller is not included.
This is the most purpose-built option here, but it is not a replacement insert for your existing bathtub. Its vertical shape may also feel less like a traditional reclined bath. Choose it if you want a dedicated, sturdy plunge tub and can make room for its height.
Pros:
- Rigid, space-saving vertical design
- Can be used with ice or a compatible chiller
- Molded step, internal bench and drain ports
- Made from food-safe resin, according to the product description
Cons:
- Upright seating may be less relaxing than a reclined tub
- A chiller is not included
Verdict: Choose the Ice Cap if you want a dedicated, rigid plunge that takes up less floor space than a long horizontal tub.
CRYDIP XXL Oval: The Most Bath-Like Portable Option
For shoppers who want one tub for warm soaking and cold plunges, the CRYDIP is the closest fit to a traditional bathtub in this group. Its oval shape and 110-degree reclined backrest are designed for a stretched-out soaking position, and the product is listed with a 200-gallon capacity. It can be used indoors or outdoors, provided you have a suitable level surface and a plan for draining it.
The tub uses 8-centimeter drop-stitch material with reinforced PVC layers to help it hold its shape when properly inflated. Its insulated lid, sidewalls and bottom are designed to slow temperature changes. Built-in inlet and outlet ports allow connection to a compatible chiller, but the chiller must be purchased separately.
Unlike a built-in bathtub, this model needs to be inflated and then drained, deflated and folded away for storage. Its large capacity may also mean more water to manage than with smaller options. It is a better match for someone seeking a flexible portable bath than for someone who wants a quick, compact cold-plunge setup.
Pros:
- Designed for both warm soaking and cold plunges
- Reclined backrest supports a more stretched-out position
- Insulated lid, sidewalls and base help slow temperature changes
- Folds for storage when drained and deflated
Cons:
- Requires inflation and setup before use
- Chiller is not included, and the listed capacity calls for substantial water
Verdict: Pick the CRYDIP if you want a portable tub that can handle both warm baths and cold plunges, rather than a cold-only setup.
Bubplay XL Cold Plunge: A Supported Tub with a Cover
The Bubplay is a portable, 105-gallon cold-plunge tub built around an inflatable top ring and eight stainless-steel support rods. The product description says it fits users up to 6 feet 7 inches, making it a practical option for taller adults who want a freestanding tub rather than a narrow upright design.
Setup is tool-free: inflate the top ring with the included pump, insert the rods and fill the tub. A fitted cover helps keep debris out and is intended to slow temperature changes. The waterproof inner liner is described as easy to wipe clean, and a bottom drain valve and included hose help with emptying the tub without tipping it.
Like other portable plunge tubs, it needs a flat surface and room around it for entry, exit and drainage. The product instructions also advise indoor use when temperatures drop below freezing. Compared with the CRYDIP, it is more focused on cold plunging than on relaxed, reclined bathing.
Pros:
- 105-gallon capacity and stated fit for users up to 6 feet 7 inches
- Support rods help the tub stay upright
- Includes a cover, pump and drain hose
- Folds for storage after draining and deflating
Cons:
- Requires assembly and inflation before filling
- Needs a level placement area and a practical drainage route
Verdict: The Bubplay is a sensible choice if you want a roomy, portable cold plunge with a cover and a more structured frame.
The Cold Pod Ice Bath: A Lightweight, Straightforward Setup
The Cold Pod is an 88-gallon portable tub with layered construction that includes a PVC inner layer, a foam middle layer and a nylon outer layer. It is designed for an upright seated plunge and is listed as suitable for users up to 6 feet 7 inches. Its included lid gives you a simple way to cover the water between sessions.
The product description emphasizes a lightweight, compact design and a bottom drainage system. It can be used indoors or outdoors, and the manufacturer suggests replacing the water about every four weeks or as preferred. A water stabilizer or UV purifier is mentioned as an option for managing water cleanliness, but neither is listed as included.
This tub has fewer support and comfort details than some of the alternatives, and the product description does not list a chiller connection. If you want to control the water temperature with a chiller, check compatibility before buying. Its simpler design may appeal if you are comfortable using ice and want a portable tub with a cover.
Pros:
- Layered construction designed for portable use
- Includes a cover and bottom drain
- Listed for users up to 6 feet 7 inches
- Can be used indoors or outdoors
Cons:
- Chiller compatibility is not specified in the product details
- Water care and replacement remain part of regular upkeep
Verdict: Consider The Cold Pod if you want a straightforward, covered plunge tub and plan to manage the water with ice rather than a chiller.
Jecoo Ice Bath Tub: A Roomy Portable Plunge with Support Legs
The Jecoo is a square portable ice bath measuring 35 by 35 by 30 inches, with a listed 116-gallon capacity. Its layered build includes polyester nylon, PVC, an inner pearl-cotton layer and a waterproof coating. The product also has eight support legs intended to help keep the tub stable.
The soft inflatable top ring is designed as a cushioned place to rest your arms or neck while seated. The listed package includes a manual air pump, cover, carrying bag and drain. Those included pieces make it a fairly complete portable setup, although you will still need to supply the water and ice if you are not using a compatible temperature-control system.
Its square footprint may be easier to position against a wall than an oval tub, but you should measure carefully before filling it. The listed capacity means it is not a small amount of water to drain or replace. Compared with the Cold Pod, the Jecoo offers more stated capacity and support legs; compared with the Bubplay, it has a square shape and a larger listed capacity.
Pros:
- 116-gallon capacity in a square 35 × 35-inch footprint
- Eight support legs are designed to add stability
- Includes a cover, manual pump and carrying bag
- Layered construction with a cushioned inflatable top ring
Cons:
- Requires inflation, setup and a flat placement surface
- Its listed capacity can make filling and draining a significant chore
Verdict: Choose the Jecoo if you want a larger portable plunge with support legs and useful setup accessories included.
How to Choose a Tub for Turning Your Bathing Area into a Cold Plunge
Decide Whether You Want to Use Your Existing Bathtub
If you already have a bathtub, you may be able to use it for occasional cold-water sessions without buying another tub. Check that it holds water properly, is clean, and gives you enough room to sit safely. For frequent use, a separate plunge tub may be easier to set up or maintain, but none of the products in this guide is a retrofit insert for a built-in bathtub.
Measure the Space and Check the Filled Weight
Measure the tub’s footprint and height, then leave room to get in and out safely. Also consider the water volume: a filled tub is heavy, so confirm that the floor and placement area can handle it. This matters especially for indoor use, upper floors, and large-capacity models.
Choose a Shape That Fits Your Plunge Position
A vertical tub can use less floor space while keeping you seated upright. An oval tub with a reclined backrest may feel more like a conventional bath. Square and round portable tubs offer other space and seating trade-offs. Think about whether you prefer to sit upright, stretch out, or have room to move your legs.
Plan for Ice, Chiller Use and Water Changes
Ice-only setups avoid buying a chiller, but you will need to add ice when you want colder water. Chillers can help control temperature, but check the tub’s port size and connection details before choosing equipment. Also plan where water will drain and how often you will clean, refill and maintain it.
Compare Materials, Support and Storage
Rigid tubs generally stay assembled, while inflatable models need setup and may fold away when drained. Check how each tub is supported, what accessories are included, and whether the materials suit your intended indoor or outdoor location. Covers can help keep debris out and slow temperature changes, but they do not replace regular cleaning.
Prioritize Safe Entry and Exit
Cold water can make movement feel more difficult, so consider the height of the tub, the grip of the surrounding floor and how you will get in and out. A molded step or stable support structure may help, but it does not remove the need for care. Avoid placing a tub where water spills could create a slippery path.
Frequently Asked Questions
Can I turn my regular bathtub into a cold plunge?
For occasional use, you may be able to fill a suitable bathtub with cold water and add ice. Make sure the tub is clean, holds water correctly and is safe to enter and exit. The products in this guide are separate tubs, not attachments that convert a built-in bathtub.
Which product is most like a regular bathtub?
The CRYDIP is the closest match because it is an oval portable bathtub designed for both warm soaking and cold plunges, with a reclined backrest. It still needs to be inflated, filled and drained like a portable tub.
Do these tubs include a water chiller?
No chiller is listed as included with these products. The Ice Cap and CRYDIP descriptions mention ports for compatible chillers. Check the product details and connection requirements before purchasing a separate chiller.
Which option takes up the least floor space?
The Ice Cap has a 29-inch diameter and a tall vertical shape, which gives it a smaller stated footprint than the larger oval and square options. Measure your available area, including room to enter and exit, before choosing.
How often should I change the water?
That depends on how often you use the tub, how you keep it clean and whether you use any water-treatment method. The Cold Pod description suggests replacing water about every four weeks or as preferred; follow the instructions for your specific tub and any water-care products you use.
Are cold plunges safe for everyone?
No. Cold-water immersion can pose risks, especially for people with certain health conditions. Ask a healthcare professional whether it is appropriate for you, enter gradually, and stop if you feel unwell. Do not use a plunge tub alone if you may need help getting out.
Final Recommendation
If you want a single portable tub for both warm bathing and cold plunges, the CRYDIP is the most bath-like choice. For a dedicated plunge in a smaller floor area, consider the vertical Ice Cap. The Bubplay, Cold Pod and Jecoo each offer portable cold-plunge setups with different mixes of capacity, support and included accessories. Choose based on your space, preferred seating position, water-care plan and whether you want to use ice or a compatible chiller.
