Harvia 20 SL Wood-Burning Sauna Stove (WKPR20SLM)

Harvia's most popular commercial-grade sauna stove. The SL — sivuluukku, side-loading — has an extended firebox that pokes through the sauna wall, so you can feed logs in from the changing room or outside without letting cool air (or smoke) into the hot room.

Suits saunas from 8 to 20 m³— comfortably enough for anything from a family panel-built sauna to a small commercial suite. Solid Finnish build, decades of design refinement, and the peace of mind of Harvia's warranty.
