Renu Therapy
Insulated cold plunge tubs with integrated chillers, plus barrel and indoor saunas.
Renu Therapy is best known for the Cold Stoic line of insulated plunge tubs, which the company says are designed and assembled in Southern California. Most models plug into a standard 120 volt outlet and pair a chiller with filtration and ozone in one cabinet. Renu also sells barrel and indoor saunas built around Harvia KIP and Virta heaters.
