All hot tubs require some form of sanitation to prevent the growth of harmful bacteria and algae, which typically involves the use of chemicals like chlorine or bromine. However, there are alternatives that minimize chemical use, such as saltwater systems, ozone generators, and UV light systems, which can reduce the need for traditional chemicals while still maintaining water hygiene. Completely chemical-free hot tubs are not practical or safe, as some sanitation method is necessary to ensure water safety.
