Harvia 36 Duo Wood-Burning Sauna Stove & Fireplace
Create a traditional sauna experience with the Harvia 36 Duo Wood-Burning Sauna Stove. Combining a sauna heater with a fireplace, its through-wall design lets you heat the sauna while enjoying the fire from an adjoining room.
The stainless steel outer casing and large, steel-framed glass door give the Duo a distinctive appearance. Inside the sauna, a substantial stone bed stores heat for steam when water is poured over the heated stones.
Designed for larger sauna rooms, the 36 Duo offers external wood loading and floor-standing installation. A compatible pipe-mounted water heater is available separately.
