The Cold Stoic 3.0
**The Cold Stoic 3.0 is Renu Therapy's flagship cold plunge system, offering dual temperature control so you can cool water down to 37°F or heat it up to 104°F for both cold and hot immersion therapy.**
It's built with an intuitive touchscreen interface, WiFi app control, and an advanced dual-stage filtration system for cleaner water with minimal maintenance. Handcrafted in Southern California, it's designed for people who want a genuinely premium, low-hassle plunge experience rather than a stripped-down basic tub.
