High-Flow Chiller

Our 1/2 HP water chiller can be set to chill the water temperature down to as low as 39F (3.9C) & our magnetic drive water pump works with quiet, efficient, and reliable 24/7 performance. Featuring a magnet impeller assembly and an epoxy-encased power unit, our pump cycles an amazing 20 Gallons every minute and never gets contaminated with harmful oils or chemicals.Also, integrated into our system is a 2-stage filtration system with a removable large grate that catches larger debris and a flow-through, replaceable 50-micron water filter element for fine particles. Finally, our ultraviolet ozone generator discharges ozone into the water to help eliminate bacteria, viruses, and metals.

Intelligently Engineered, Designed, & Assembled in USA.

Our cold tanks are designed to last years. For example, our tanks feature a fully enclosed housing for the chiller system to ensure the longevity of all the electronics and pumps. Our tubs are Super Insulated for maximum efficiency and have a Leak Proof tank design. All of our products are constructed with the highest-quality components and have been extensively tested. Performance and reliability were considered in every step of our design process. Finally, we proudly design and assemble all of our cold tanks in Southern California.

Beautifully Designed for Indoors or Out

Customize your tank for your gym, garage, or outdoors space. Our designs are minimalist, modern, and can match any environment. We believe quality design deserves the best materials. We use beautiful Natural Woods like Cedar and Redwood, which are treated with all natural oils and no chemicals. Every unique unit has its own artful characteristics.

Quiet and Energy Efficient

Our fully sealed design combined with our custom high-flow chiller allows your cold tank to operate at a whisper.  You’ll barely notice it’s there! Our thermally insulated tub keeps water colder and separated from the elements.  This allows the chiller to work more efficiently and saves 30% more energy compared to other cold tanks.  Our tanks are so well insulated, that in our tests, water stays below 60 degrees F even 24 hours after we've fully unplugged our unit.

Perfection- the cold plunge and the service!

Perfect gift for my husband. He’s 6’2 and fits. It looks great near the hot tub. We alternate hot tub, cold, etc Love the Siberian cold! Thanks for the great service too!

Jade Goodyear (Bella Vista, US)
Taking the Plunge

This cold plunge is a great addition to our facility. Members are loving it. We were a bit surprised with the higher level of maintenance it requires. Very frequent (almost daily) filter changes needed, a new cover needed (our handle ripped off quickly), and just more attention to this unit then we had originally thought. Steve has been great with helping us work through these challenges and we appreciate his help. Hoping to get our maintenance dialed in for this unit so it is more manageable and feasible.


Thanks for the kind words. As we had mentioned in the beginning, commercial use of a cold plunge will lead to many more filter changes than regular residential use, but we will continue to work together to minimize the amount of maintenance required for your plunge.

Best Investment for Health

Haven't missed a day since it arrived. 46゚ water every morning for 10 minutes has seemed to be the best. Tried 45 minutes but that seemed to long. The whole family loves it. I now use a snorkel so I can keep completely submerged. Love it.
