The Harvia 50 SL is built for big sauna experiences. Designed for large public or commercial saunas, this powerful heater holds a massive amount of stones, delivering steady, even heat for large groups.

The SL (side-loading) design allows you to load wood from an adjoining room or outside the sauna, keeping the heat in and the space clean. With its classic black finish and traditional Finnish performance, the Harvia 50 SL brings authentic, efficient heat to high-capacity sauna spaces.

Ideal for camps, gyms, and other shared wellness areas.
