About

Saunarium M15 is a cluster of timber saunas on Sopot beach, beside the M15 restaurant. Wide windows look out over the Baltic, and guests cool off with a dip in the sea. Saunamistrzowie lead aroma seanse, and a sauna can be hired for a private group.

Good to know

  • Runs aufguss sessions: a guided löyly ritual where an attendant fans the steam around the room on a schedule.
  • Bar on premises: drinks alongside (or after) the session, and the venue isn't dry like most outdoor sauna setups.
  • 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.
  • Restaurant on site, so long sessions are the design. Food is part of the visit rather than a stop on the way home.
  • Urban venue: it sits inside the city rather than at a coast or lake. A session fits into a day in town.
