If you are looking to get additional uses out of your sauna stove than this Harvia M3 SL is the stove for you. The M3 SL is placed in the sauna room and your firewood is loaded into the fire chamber from the other side of the wall. The M3 SL will give your small or medium sauna great steam. While someone is enjoying the heat in the sauna room another bather can be relaxing in the next room while appreciating the glow of the flames behind the cast-iron-framed glass door.
