The concept and construction of the floating sauna in 2002 is the result of a workshop lead by Finnish teachers and architects Sami Rintala, Christel Sverre and Marco Casagrande, together with Västlands Kunstakademie, Bergen.
Anchored in the middle of the Hardangerfjord, inhabitants of the village Rosendal in Norway can access the sauna with rowing boats. They can enter and exit it by swimming straight through the wholes in the floor. The structure is made of pinewood, while the walls are made of transparent plastic to allow daylight to come through. At night the sauna shines as a floating lantern.
The interior has an area of 9 sqm, total with floating dock of 25 sqm.
