    Cold Tank Benefits

    Strength of Character

    We believe quality design deserves the best materials. We use beautiful 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. The 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. The 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

    Unlike a dangerous modified meat freezer and potential electrocution, the Cold Stoic Plunge Tank is weatherproof, safe around water, and always COLD, eliminating the need to buy and haul ice before it melts.

    Cold You Can Rely On

    Our chiller provides a high-performance titanium heat exchanger for optimum performance and corrosion resistance, making sure that your daily routine is the ultimate cold therapy.

    Natural Sanitation

    Using advanced plasma gap technology and the world’s most advanced solid-state Corona Discharge technology, our ozonator 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 en 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%.

    Whole Family Is LOVING THIS!

    So grateful to Bill and the whole team at Renu Therapy! We absolutely love the Cold Plunge. In just a week we have seen increased energy and mood. And a plus we didn't expect... it has become a family ritual each night before we go to bed. Our son is loving it and we are bonding over our time moving from the Hot Tub to the Cold Plunge as a way to decompress our day and get better sleep.
    And it's been great for gatherings as well since everyone wants to try out the cold plunge!! I'm so excited to start my day with a plunge!

    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 Express 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 components need replacing within the 5-year Express Warranty period, our goal is to make sure you have a replacement part delivered "Before you RENU loses its cold temperature! We also are able to ship out filters, Spa Sponges, as well as a Mineral Sanitizer sticks every 3 months, so you can maintain clean and cold water.
