Harvia PRO 36 DUO 31kW Wood Burning Sauna Stove / Heater | WK360SLUX

Harvia PRO 36 DUO 31kW Wood Burning Sauna Stove | WK360SLUX

Enjoy the best of both worlds with the innovative and versatile Harvia 36 Duo. Both a wood-fired sauna stove and a fireplace! A unique solution to heating two rooms with one stove. Relax in an intense, steamy sauna room, then move to the next room to enjoy the warm glow of a fireplace. 

The Harvia 36 Duo lets you load wood into the sauna stove from an adjoining room so you don't need to bring messy cordwood into your sauna. Harvia wood-fired sauna stoves are both attractive and incredibly high quality with an outer casing designed from durable, premium-quality stainless steel. The stylish glass door creates a beautiful fireplace and Harvia's wood burning technology will ensure the best traditional sauna experience.
