Freezing cold and clean water any time of the day


The Supertub is powered by our energy-efficient Permafrost™ chilling system that keeps your water as low as 37.4°F (3°C) throughout the day.

It’s engineered to be powerful enough to keep the water ice-cold, while making sure it does not overwork.

The Supertub comes with a built-in 3-step self-cleaning sanitization system:

Step 1: The 80-mesh water strainer traps larger debris like hair and sand.

Step 2: The 20-micron water filter removes ultra-fine sediment and dirt.

Step 3: The commercial-grade ozone generator disinfects the water by breaking down microbes like bacteria, viruses, and mold.

Super simple

The Supertub is designed to fit homes of all sizes, and is suitable for use indoors or in sheltered outdoor spaces. In addition to its small footprint, it also has a self-contained filtration system so no plumbing is needed.

With its sturdy but lightweight inflatable design, the Supertub is easy to move around, and can be set up and taken down without professional help.

It’s also built to last– constructed from double-walled military-grade marine vinyl that we put through rigorous tensile, tearing, and adhesion strength tests, and that is SGS- and ISO-certified for safety and quality.

What does the Supertub do for your body?

Boosts physical recovery

A systematic review of 52 studies showed that cold water immersion is effective in aiding recovery after high-intensity exercise when done 6-8 hours after training or before training.

Increases energy and focus

Cold water immersion triggers the release of adrenaline and noradrenaline in the brain and body. These hormones make you feel more alert even for many hours after your cold plunge.

Builds mental fortitude and grit

Doing hard things intentionally is hard, but necessary at times. By forcing yourself to face and embrace the stress of cold water immersion, you train and strengthen your prefrontal cortex—the area of your brain that controls impulses and reflexivity.

Enhances your mood

Immersing in cold water has been shown to increase the production of beta-endorphins and dopamine—which can give a natural high and improve symptoms of depression.

Speeds up metabolism

Going in an ice bath activates the body to burn calories in order to stay warm. The white fat (energy storage) in the body is also converted into brown fat, which the body uses to regulate temperature—which may result in sustained increased metabolism.

    Harness the power of the cold with the Supertub

    Frequently asked questions

    The Supertub can be used both indoors, and outdoors in a sheltered area.

    The Supertub is designed to be set up by one person in as little as 15 minutes. Setup is simple and requires no special tools, and we provide comprehensive step-by-step video instructions to guide you through the setup process.

    For a limited time, we're also offering our Singapore customers a white-glove setup service, where a member of our team will come down to help you set up your Supertub and give you tips on usage and maintenance. You may book this service at no extra cost after you make your purchase.

    Once you’ve purchased your Supertub, you'll receive an email with the subject line "We've got your order!" Scroll down to the section titled "Booking a setup appointment" to find a calendar link where you can book your appointment.

    The Supertub measures 52x28x24" (132x71x61cm) and can comfortably accommodate users up to 6'3" (190cm) tall and 198lbs (90kg) in weight.

    We recommend that you change the water in your Supertub every month or so.

    The Supertub has a built-in filtration and sanitization system to keep the water clean. It comes with a 20-micron filter that removes ultra-fine sand, sediment and dirt, as well as an ozone generator to eliminate pollutants, microbes and mold. The Permafrost™ chiller is also designed to be kept on 24/7, which prevents the water from stagnating and keeps it fresh and clean.

    Every purchase of the Supertub also comes with a free Water Balancing Kit, which includes a chlorine- and bromine-free sanitizer and oxidizer and a pH balancing kit to help keep your water clean, clear, and properly balanced.

    We recommend starting at a higher temperature (e.g. 50°F (10°C)), and gradually lowering the temperature over several sessions as your body gets used to the cold.

    The water should feel uncomfortably but not painfully cold in each session. We also recommend starting with less frequent sessions (e.g. 2-4 times a week) and gradually increasing session frequency as you become more comfortable with the routine.

    Finally, we recommend starting with shorter sessions (e.g. 1-2 minutes) and increasing to up to 5 minutes as you become comfortable.

    While using the Supertub, pay attention to how your body is responding to each session, and make sure you are using the right temperature settings and session durations for you. If you feel any unexpected pain or discomfort during a session, stop use immediately and consult your physician.

    As a safety feature, the Supertub is programmed not to operate in ambient temperatures below 32°F (0°C) or above 113°F (45°C). At these temperatures, water flow from the tub to the chiller will not turn on even if the "Switch" icon is pressed.

    Ambient temperatures above 113°F (45°C) may damage the Supertub's internal components, so in very hot weather we recommend moving your Supertub to a sheltered area where the ambient temperature is lower than 113°F (45°C) and where it is out of direct sunlight.

    In ambient temperatures below 32°F (0°C), water may freeze within the tub and chiller and cause damage to the internal components; so we recommend moving your Supertub indoors where the ambient temperature is above 32°F (0°C), or emptying the tub and chiller and making sure they are completely dry.

    The Supertub is powerful enough to chill water down to 37°F (3°C) or heat it up to 104°F (42°C). Thus, while most of our customers use the Supertub as a cold plunge, it can also be used as a hot tub.

    Each Supertub order comes in three kits: the Supertub Kit, the Permafrost Chiller™ Kit, and the Water Balancing Kit.

    The Supertub ships from our warehouses in Singapore and the United States.

    The Supertub is only available in and ships to Singapore and the United States.
