Sauna Heaters — Electric, Wood-Burning & Commercial

Browse our complete catalog of sauna heaters from trusted brands like Harvia, Huum, Scandia, and SaunaLife. Whether you are building a backyard barrel sauna, retrofitting an indoor sauna room, or equipping a commercial facility, we carry heaters sized from 3 kW for compact personal saunas up to 18 kW for large commercial installations.

Electric sauna heaters are the most popular choice for residential use — they heat quickly, maintain precise temperature control, and require no chimney or venting. Wood-burning sauna heaters deliver a more traditional experience with the crackling sounds and natural aroma that many sauna enthusiasts prefer, particularly in off-grid or rural installations where electricity may be limited.

Every heater ships with a manufacturer warranty (2 to 10 years depending on the model) and includes detailed installation specs. Need help sizing a heater for your sauna? Use this rule of thumb: multiply your sauna's cubic footage by 1 kW per 45 cubic feet. Our team is also available at howdy@sweatdecks.com for personalized recommendations.
