A Word From Our Founder

Hey There, I'm Bill

I am a life-long entrepreneur who loves family, skiing, tennis, and surfing. At age 53, I am still striving towards bigger goals and leveraging every trick and technique to stay in the game longer. I started looking for the perfect cold tank after learning about the Wim Hof Method.

During a ski trip, I happened upon a broken jacuzzi filled with ice cold water. I discovered that Cold Water Immersion had a total game-changing effect on my physical recovery and mental performance.

Upon returning from my trip, I started researching cold plunge products and was unsatisfied with every cold tub or plunge on the market. I decided to design one that I would be proud to put on my backyard deck. I also wanted it to always be clean and cold, easy to operate, and have all of the chiller equipment protected from the elements.

I created the original Cold Stoic as a tribute to Stoicism which has helped me with the challenges of life and business. I developed what I think is the perfect product for the forward thinkers and high performers who want to integrate the power of cold water immersion into their daily lives. Just like that, Renu Therapy was born.
