About
A floating sauna and pool complex in Helsinki's harbour, directly opposite the Market Square and the Presidential Palace. 3 saunas and 2 pools, one heated, one Baltic seawater. Touristy by Helsinki standards, but the setting is unbeatable and the sea pool in winter is genuinely bracing.
Good to know
- Cold plunge available on site: use it between rounds for the classic contrast 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.
- Urban venue: it sits inside the city rather than at a coast or lake. A session fits into a day in town.
- Women-only sauna: the venue has a women's side or room, or runs set women-only sessions.
- Mixed sauna: men and women share the room, in every session or on set days.
- Nude sauna: some or all sessions are taken without swimwear.
- Swimwear sauna: some or all sessions are taken in swimwear, so pack it.
