A large sauna room with many steps. With a twin-tower setup combining a convection stone stove and a gas far-infrared stove, it delivers a stronger heat than the room temperature alone would suggest. During the automatic löyly held every 15 minutes, aroma water is poured over heated sauna stones, and the steam that spreads all at once encourages a pleasant sweat. In the spacious room, you can choose a temperature zone that suits you and spend time at a relaxed pace.
