Experience comfort and efficiency with the Harvia Pro 20 SL Wood-Burning Sauna Stove — a dual-function heater designed to deliver authentic Finnish warmth to your sauna while creating a cozy fireplace atmosphere in the adjoining room.

The stove is installed inside the sauna, while firewood is conveniently loaded from the opposite side of the wall, allowing you to heat the sauna without bringing wood indoors. Its cast-iron glass door lets you enjoy the soothing view of the flames, whether you’re relaxing in the sauna or unwinding next door.

Perfect for small and medium-sized saunas from 283 to 706 cubic feet, the Harvia Pro 20 SL ensures consistent heat, efficient wood use, and a naturally relaxing experience.
