Perfect for both indoor and outdoor settings, our system integrates seamlessly into your lifestyle at an affordable price point. Using high-quality materials and advanced insulation technology, the SISU Cold Plunge guarantees a cold, refreshing experience every time.

Our Base: The Grizzly Tub

Our system is built on the rotomolded Grizzly Cold Plunge, renowned for its exceptional insulation capabilities. With up to two inches of pressure-injected polyurethane foam, it ensures efficient cooling and impressive water temperature retention. Unlike most tubs, the SISU Plunge features a weatherproof, sealed lid that significantly enhances thermal efficiency, leading to considerable energy cost savings.

Tub Key Features:

• Premium Insulation: Engineered with polyurethane foam and gasket sealed lids for superior temperature retention and  reduced energy consumption.

• Generous Size: At 24” deep, the tub allows for full submersion up to the neck and is spacious enough to dunk your head if you’re feeling extra brave. We’ve had individuals up to 6’7” tall using the tub and can fully submerge comfortably. Also fits 2!

• Portable: Weighing in just under 100 lbs when empty it is equipped with built-in molded handles for easy maneuverability.

• Easy Setup and Draining: 3/4” standard Garden Hose Thread Connections for convenient and quick draining.

How are we different? 

Our SISU Plunge stands out for its superior design and efficiency. While many tubs struggle with poor insulation and flimsy foam lids, our system uses a robust, weatherproof lid similar to those found on top-tier coolers, ensuring water temperature is maintained consistently. This not only cuts down on energy costs but also enhances the overall experience. Additionally, unlike tubs with canvas-wrapped lids that are prone to bacterial growth in outdoor settings, our SISU Plunge remains clean and safe, making it a smarter choice for your wellness routine.

What is a cold plunge chiller?

A cold plunge chiller is a system that agitates water through a heat exchanger to maintain a consistent temperature, much like an air conditioner but for water. This constant circulation ensures the water remains chilled and ready for a plunge whenever you need it.

What size chiller do I need for a cold plunge?

For a cold plunge, you typically need a chiller of at least 1/2 horsepower. However, in extremely hot climates, a 1 horsepower chiller is recommended to consistently maintain <45F water temperature, ensuring it stays cool even in warmer weather conditions or with frequent use.

Can you use a water chiller for an ice bath?

Yes, you can use a water chiller for an ice bath. By maintaining the water at a consistently low temperature, the chiller eliminates the need for actual ice, making it an efficient and convenient option for ice baths.

What does a cold plunge actually do to a body?

A cold plunge does several beneficial things for the body: it reduces muscle soreness and inflammation, enhances recovery through improved circulation, and boosts the immune system by stimulating the production of white blood cells. Additionally, it can increase energy levels through an endorphin rush and improve mental health by reducing stress levels.

Do cold plunges burn fat?

Yes, cold plunges can help burn fat. The exposure to cold activates brown fat, a type of fat tissue that burns calories to generate heat. This process can aid in weight management by making brown fat work more efficiently.

How long should you stay in a cold plunge?

The recommended duration for staying in a cold plunge is between one to three minutes. This time frame is ideal for maximizing the benefits while ensuring safety. Beginners should start with shorter durations, such as 30 seconds, and gradually increase the time as they build tolerance. Please consult with your physician before cold plunging.

How often should you cold plunge?

It is recommended to cold plunge two to three times per week. This frequency is optimal for balancing the benefits with recovery time, especially for those who are also active in other physical activities. Starting with fewer sessions per week and increasing as your body adapts can help prevent overexertion.
