About Hot Then Cold

Hot Then Cold is a buyer's guide for people putting a sauna, a cold plunge or both at home. We compare products on what decides the purchase — size and capacity, heater type and power, wood and build, electrical and plumbing needs, chiller temperature range, warranty, delivery and the full installed cost — using manufacturers' published specifications, pricing pages, owner's manuals and warranty terms. We say plainly when we have not used a product ourselves, and we never publish made-up test results or reviews. Some links on this site pay us a commission if you buy.
