Sauna Ferry m/s Spa
Helsinki, Finland
About
A wood-fired sauna boat moored at the Mustikkamaa marina in Helsinki, run by Saunalautta.fi alongside its smaller m/s Sauna. The 12-metre vessel takes sixteen at the dock, with a heated hot tub, a sheltered lounge and a ladder into the sea. It is booked whole, by the shift or as a cruise.
Good to know
- Hot tub on site: adds a warm-water option between the sauna and the cold plunge for a longer cycle.
- Right on the sea: expect saltwater dips between rounds, cold even in summer.
- Set up outdoors: weather is part of the experience, so dress for the walk between cabin and water.
- Bookable as a private session: rent the room for your group rather than sharing with strangers.
- Urban venue: it sits inside the city rather than at a coast or lake. A session fits into a day in town.
- Wood-fired heat: softer, heavier löyly than electric, and the smell of the stove is part of the room.
Hours
- Hours not listed
