Narvi Stony is a Finnish-made Key Flag product, also available as a tunnel stove with a fireplace-style firebox. The tunnel model keeps the sauna room dedicated to bathing while the glass hatch creates atmosphere in the adjacent space.
With a large stone capacity, Stony delivers soft, humid steam and a traditional sauna experience. The fireplace model is available with a stainless steel casing, wooden handles for comfort, and a double base for easy installation.
The tunnel is designed for a 12.3 cm wall thickness with a 16.8 cm tunnel length, ensuring safe clearances. Installing the heater on a mounting base will affect its overall height
