Morozko maintains freezing cold temperatures and sanitizes your water without chlorine.  Unlike a cold tub, a cold plunge, or a cold shower, Morozko ice baths make their own ice.  Microfiltration and ozone disinfection ensure crystal-clear cold water, empowering daily cold plunge therapy practice year-round.  

Morozko is designed to support a healthy lifestyle, not diagnose, cure, or prevent specific diseases or medical conditions.  Morozko ice baths are not medical devices, and have not been evaluated by the FDA. Seek medical advice from your physician before embarking on any program of deliberate cold exposure.
