Electric Sauna Heater vs Infrared Sauna: Which Costs More to Run? (2026)

An infrared sauna uses about a third of the electricity of a traditional electric sauna per session. It heats the body directly with 1.2 to 3 kW panels and needs only ten minutes to warm up, while a traditional sauna heats the whole room and its rocks with a 6 to 9 kW stove for half an hour or more before use. Traditional saunas win on heat intensity and steam.

At the hours shown, Electric Sauna Heater costs about $401.65 a year and Infrared Sauna about $90.37 in the US.
