Harvia 20 SL Wood-Burning Sauna Stove (WKPR20SLM)

Finland's most popular commercial-grade sauna stove — and once you fire one, you'll understand why. 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, an outside lobby or even the garden — without opening the sauna door and letting cool air (or smoke) into the hot room.

Suits saunas from 8 to 20 m³ — enough for anything from a family panel-built sauna to a small commercial suite. Solid Finnish build, decades of continuous design refinement, and the peace of mind of Harvia's warranty. This is the workhorse we specify for most of our own commissions.
