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%.

Hooked

Worth the wait. I’m hooked. Already trying to do 2x a day as many days as possible. Solid, easy to assemble and easily the the highlight of 2023. Thank you to the entire Renu team!

Gopi's Temple of Renu

Gopi is was born in the Himalaya's and calls her cold plunge Gopi's Temple of Renu. Many definitions of Renu, but the most applicable definition is an "atom" from which we are all made.

Thank you so much for the 5 star review and beautiful pictures!!

Great product, great customer service

I use it everyday and highly recommend this product. I live in S Florida, where it's often in the 90s+, and our chiller is maintaining low 40s (while set to 42, you can set it at 36). I'm sure if I moved it to full-shade (it gets ~2hrs of direct sunlight / day) it could get sub-40.

Excellent customer service as well! Unit arrived with one hose that was a little too short, so I called to ask, and they immediately sent out a replacement along with a plumber to install / fix the short hose, no charge.

I'm one month in and have changed the filter and water once. Both were incredibly easy to do.

Great tub, bit noisy

Overall I'm happy with the cold plunge tub. I do think the chiller generates too much noise. Given it's width, I couldn't put in the room I originally wanted, so it's in a common area and while not super loud, there's definitely a constant "white noise" going 24/7. Other than that, it's great.

Best thing ever!

Loving the discipline and comfort, well “comfort”, you have brought to my life. My 3 year cold shower habit is just a memory as this 3 minute ice bath is so much more effective. Great product and great help from the team.

Step to wellness

After 28 yrs of service to our great nation this was my 1st step to wellness for myself, I truly appreciate the Renu team in assisting me in this healing journey. I am grateful for every morning that I get to start at 36’ in my tub.

Overview of Cold Plunging

Less thinking and more Cold Plunging

For those who know the Power of an ice bath tub, the problem has always been, "How can I get my daily cold bath conveniently and safely without breaking the bank? The RENU Cold Tank was designed to be Cold, Clean, and ready for you every time. Cryotherapy is such an expensive hassle that most people are not consistent with during the week, and end up spending money without receiving any benefits. Getting ice is also a hassle that can be difficult to stay consistent with and requires tons of work and additional expenses. Although the DIY cold bath is at home, it is so unsafe and dirty that it should not be an option. The Health Benefits for cold plunging are Real and will change your life.....if you go into the Cold Daily. Finding a clean, safe, and convenient method to cold plunge will help you experience these benefits. No excuses, just jump in when you wake up and Charge your day, every day!

Earn your Health Benefits Daily with a Cold Plunge

The health benefits for cold plunging daily are a Robust Immune System, Less Inflammation, less arthritis, Healthier skin, Increased Thermogenisis (the ability to warm yourself), and increased Happiness. It sounds too good to be true, but it is not. You simply have to "Earn your Health Benefits" by jumping into your RENU Cold Tank daily. Much like exercise, it has to be earned. With Cold Water Immersion, most benefits take a few weeks before you start to notice; with one exception.....your Happiness. You always feel amazing when you get out of Cold Water, and that mood boost will be with you all day. You will feel like you have a Secret Weapon for achieving your goals!

Handmade to last, and backed up by a 5-Year Limited Warranty!

Each RENU Plunge Tank is built to last. The Exterior treatments are designed for indoor or outdoor use. UV Protection and specialized waterproofing enables you to focus on your Daily Routine and Health. The Mechanics of the RENU tanks are designed to be User Friendly, and should any of the covered components need replacing within the 5-year Limited Warranty period, our goal is to make sure you have a replacement part delivered promptly!
