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.
-

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.

WHY SISU?
Elevate your well-being
2x Chilling Power
The 1HP (horsepower) chiller is designed for rapid cooling efficiency, enabling you to bring the water to your desired setpoint temperature quickly (as low as 4°C or 39°F). This powerful cooling capability optimizes for both speed and stability in reaching and sustaining the perfect water conditions for your needs.
Superior Efficiency
Our system is engineered for optimal efficiency. Unlike most tubs that lack proper insulation and feature foam lids resting atop a thin wall, SISU Plunge incorporates a sealed weatherproof lid specifically designed to retain cold. This design significantly reduces the frequency of chiller operation, leading to substantial energy cost savings.
Clean Water
The chiller features a built-in 5-micron filter and Ultra Violet (UV) sanitation for maintaining water purity and clarity. This sophisticated system eliminates impurities and microorganisms, ensuring that the water remains pristine and hygienic. The UV sanitation process, in particular, provides an added layer of protection by neutralizing harmful bacteria and viruses, offering peace of mind about the cleanliness of the water.
Any Place Any Time
The chiller's hoses are effortlessly detachable from the tub, and the molded handles make it convenient to move your SISU Plunge wherever you desire. This design enhances portability, allowing you to plunge in any location with access to running water and electricity.
Improves Circulation
Cold water constricts blood vessels, pushing blood back to the heart and promoting better circulation
Reduces Muscle Inflammation
Cold plunging after physical activity helps reduce muscle soreness and inflammation, aiding in quicker recovery
Enhances Mood
Cold water stimulates endorphin production, the body’s natural painkiller and mood elevator
Increases Metabolism
When exposed to cold, the body works harder to maintain core temp, increasing metabolic rate and aiding in weight management.
Improves Lymphatic Drainage
Cold water promotes lymphatic drainage, which helps remove toxins and waste from the body.
Enhances Mental Alertness
The shock of cold water triggers a natural response in the body, releasing adrenaline and increasing overall alertness.
Reduces Stress
Cold water reduces levels of cortisol, the stress hormone, and over time helps the body build a natural resilience to stress.
Improves Sleep Quality
Cold water immersion re-activates the parasympathetic system which helps with sleep quality.
" Cold is a stressor, so if you are able to get into the cold and control your body’s response to it, you will be able to control stress."
" Cold exposure may reduce inflammation in the brain by reprogramming the immune system. Cold promotes the browning of adipose tissue, which creates an energetic trade-off at the expense of T cell activation: a benefit in the context of neuroinflammation."

Let customers speak for us
The only negative part of this is that shipping and delivery was not instant. Once it arrived, I have used it every day for a few weeks. The tub and chiller are MUCH better than the cheap tub and 100 lbs of ice I was using everything. So far, everything appears to be quality. Their customer service was extremely responsive when I was asking about the status of it being shipped. Would recommend.
Great customer service from the reps, who helped with delivery and setup. I’ve enjoyed the machine so far, keeps the water cold and gets the water cold fast!
Very happy with this purchase. Use it every day. Customer service, is second to none. Recommend this company to anyone looking for a plunge.
We started cold plunging in LI Sound a few years ago, then graduated to a farm tub in driveway with ice, and finally when mid summer ice-making grew too onerous, we jumped to the SISU. The convenience is extreme compared to ice making. And that of course leads to more regular dunking which is a very wonderful thing, if you like the idea of having super powers. We haven't used it that long because we were away some but so far we are very impressed with it, no issues at all. I'd be happy to review further in detail after 2 months if SISU reaches out. Till then, Yours in Ice Plunging. Thank you to Wim Hoff for popularizing this ancient practice. Cheers!
The SISU Plunge is a lifesaver in this Arizona heat! The 1HP chiller is quite capable and keeps the water at the desire temperature, even when it's 110F outside. The Grizzly cooler is also great. UV light and filter keep the water clean without much hassle. It's amazing for recovery and beats out the other units I've tried. Highly recommend!
I am currently training for my third marathon and have seen such a big difference in cold plunging for recovery. I got tired of buying bags of ice, and needed something I could quickly use every day-- I am OBSESSED with my sisu!! Highlyyy recommend if you're looking to make this a part of your wellness routine. Also a huge bonus is everything is fully insulated and ip67 rated!
You won't regret it!!
Being a competitive pickleball player, finding a cold plunge that aids with muscle soreness and recovery was crucial. The Sisu cold plunge has exceeded my expectations. I love how I can easily control the water temperature, and the airtight lid ensures the water stays clean and fresh. Highly recommend it!
I recently purchased the SISU Cold Plunge System with a 1 HP Chiller, and I couldn't be more satisfied with this investment for my home. The tub is massive, and as someone who is 6 feet 3 inches tall, I fit comfortably with room to spare, making the plunge experience both relaxing and effective. The system arrived in one box on a pallet, making delivery straightforward, and setup was surprisingly easy with clear instructions. The tub itself is super high quality, extremely durable, and well insulated, making it perfect for outdoor use. So far in this Texas heat the 1 HP chiller works efficiently, and has maintained the perfect cold temperature for me (44F) consistently. Overall, the SISU Cold Plunge System is an excellent product that combines size, ease of setup, and top-notch build quality, making it a fantastic choice for enhancing your recovery routine or enjoying the benefits of cold water therapy. Highly recommended!
