Like an island floating on the water, this sauna, with one half of its panorama window underneath the surface of the lake, offers a very special experience. The construction rises like a wave, with the majority of its volume under water, like an iceberg. One enters over golden yellow larch planks, which bring to mind a sandy beach. The roof is an inviting place to cool off and chill out. Down below is the sauna area, with two temperature zones, as well as a changing room and lavatory. A rowing boat is used to get to and from shore. And the recreational island is anchored in position and supplied with electricity via a thick underwater cable.
