Cold Tank Benefits
Strength of Character
We believe quality design deserves the best materials. We use beautiful Natural Woods like Cedar and Redwood, treated with all natural oils and no chemicals. Every unit has its own artful characteristics, and is unique.
Always Cold And Ready For Your Morning Routine
You choose exactly how cold you want to be. Cold Stoic ™ constantly maintains the water at temperatures between 39 and 55 degrees. All of the cold without the work.
Always Clean And Easy To Maintain
Ozone, or energetic oxygen, is a powerful oxidizer of contaminants in water. Cold Stoic ™ naturally sanitizes water using ozone technology and a filter system reducing maintenance time and the need for chemicals.
Designed For Your Safety and Convenience
The Cold Stoic ™ Plunge Tank is the only unit that has all of the equipment inside a Weatherproof Mechanic’s Bay. Having the equipment enclosed is vital to safety and for keeping the equipment running properly!
Cold you Can Rely on
Set your desired temperature. Our chiller provides a high-performance titanium heat exchanger for optimum performance and corrosion resistance, making sure that you stay focused on your Health Routine!
Natural Sanitation
Using advanced Ultra Violet technology as opposed to the cheaper and less effective Corona Discharge, our ozone generator cleans water without the use of chemicals for long life, output, and energy savings.
20 Gallons Of Water Every Minute
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 never gets contaminated with harmful oils or chemicals.
Keep Extreme Cold Temperatures
Our Proprietary insulation fills gaps and voids to create an energy saving thermal blanket that can lower cooling costs by 25% and reduce sound power by 60%.
Customer Reviews
The device itself is great. Looks great on our patio. Installation is super easy (although you’ll need a couple buddies to move it off the pallet and to where you install). I bought this cold plunge to help with breathing exercises, accelerate metabolism and cut back inflammation and soreness from jiu jitsu, running, and lifting. I’ve also found it provides for improved mental clarity.
I am so happy with this purchase and with this company. After many months of research and waiting for my cold stoic to be built and delivered, it was all worth it. I also got the temperature down to 32 degrees which was much lower than the standard lowest setting for the chiller. I have been doing 35 degrees for 6 minutes, 5 days a week and I feel amazing! Thank you, Steve and everyone at Renu Therapy!
we love our tub. we live in florida and took a trip to renu once while out in california and bought it on the spot. my husband is an athlete and loves to do sauna and cold and we had been eyeing this tub for a long time. steve made sure it got to us in a timely fashion. we had an issue setting it up because a piece had cracked in shipment (shipper’s fault, not renu) but steve and his team found someone in florida to come over and set it up for us once the new part arrived. definitely recommend this company and appreciate their customer service.
I am very happy with my cold tank. It has improved my sleep and recovery and overall state of mind.
Although we were disappointed in the long wait time from purchase to production to installation, the Stoic is great. We use it every day and it is simple, clean and effective. Bonus, the look goes great with the aesthetics of our home and yard.
The best investment Ive ever made for my health. Addicting, invigorating, and life changing!
Absolutely LOVE my Stoic tub! I’ve been experimenting with cold for my long abused knees trying cryotherapy which worked but was going to be expensive long term to cold showers which worked well when in Colorado mountains using glacier melt but not so much in Texas. After spending the past 30 days religiously getting a soak I can say best money I have spent in a long time! My knees feel great! All the other little aches and pains you pick up along life’s path especially when you might “not be acting your age” are nonexistent. I was also excited about the mental aspect and have not been disappointed. My 30 year old son has even taken to it as a stress reliever from time to time. The design of the mechanical bay is great! Everything is easy to access and maintain. I am a very satisfied customer!!
It took a number of months to get my Cold Stoic running like a fine oiled machine. This was 100% my fault. Steve Midgley and the customer service department were the absolute best! I cannot speak highly enough about him/them. Calls on the weekends, parts shipped quickly, almost immediate email responses. I'm not the brightest crayon in the tool box.. so I'm sometimes hard to work with. They went above and beyond, they always went the extra mile. I wouldn't hesitate to purchase one of their products based on their customer service alone!
My Cold Stoic is used almost daily by 1-3 people, and almost weekly by 4 others in the family. The Cold Stoic handles this without issue. This is truly an amazing product, I'm so grateful to have it in my home. In today's world finding a product that works as advertised is hard enough. Finding a product that works better than expected, with a customer service department that truly understands customer service? That's basically impossible. But not with these guys, they're the best!
Thanks so much for the glowing review, Scott. Glad you're up and running correctly and all good to go!!
The product is great. It is aesthetically pleasing, and well finished. The product doesn’t look cheap made.
It is easy to follow the instructions, easy to clean and change the filter. Customer service - on point!!! I can't complain.
We have from 2 to 8 different people going in on a daily basis, so the water gets dirty fast. We change the filter every 10 days and replace the water twice a week. I just wish the filters were bigger for business purposes so we would spend a little less time on maintenance, even though it is super easy to do.
