A natural place for rest and relaxation, in the middle of nature

Three buildings on the southern part of the island have been carefully converted into bathhouses, which together form 7° Bath & Sauna. The name 7° comes from the average temperature on Marholmen all year round.

At the water's edge, a floating jetty with a sea sauna offers soothing views of Marholmsviken while you get your spirits up with a dip in the sea from one of the jetty's two bathing ladders. An equally wonderful experience regardless of the season and water temperature!

All furnishings are made of natural materials throughout. The area consists of two saunas, changing rooms with showers and areas for relaxation and socializing. In the best south-facing position there is a wooden balcony with hot outdoor showers for a purifying nature experience and relaxation.
