Seaside saunas in Finland

Helsinki, Finland

A small electric sauna on Itäinen Pihlajasaari, designed and built by architecture students and run by the City of Helsinki. Six people fit inside, it is used self-service, and the whole sauna is booked for a slot through the city's Varaamo service over the summer season. The island is reached by ferry from Merisatama or Ruoholahti.

Helsinki, Finland

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.

Espoo, Finland

A small seaside sauna in the yard of Villa Rulludd at Hyljelahti in Espoo, taken by one group at a time along with the adjoining cottage and grounds. The shore of the Gulf of Finland is a few steps away, and groups bring their own food and drink. Sauna evenings run through the summer.

Helsinki, Finland

The sauna section at Hilton Helsinki Kalastajatorppa sits beside an 11-metre heated pool on the Gulf of Finland shore. Two saunas are hired by the hour for groups of two to twenty, and in summer the terrace and hotel beach open straight off them. Food and drink are ordered from the hotel restaurant in advance.

Turku, Finland

Harjattula manor's beach sauna sits on the shore south of Turku, with two hot tubs beside it. It is booked privately for most of the year, and the estate opens public shifts in season. Those run to winter swimming evenings, morning saunas with breakfast, and summer Thursday sessions.

Helsinki, Finland

The rare sauna that earns the word 'beautiful' without apology. A 2013 public sauna on the Helsinki waterfront designed by Tuomas Toivonen and Nene Tsuboi, with a birchwood interior and direct access to the sea. It gets busy on summer evenings, which adds to it, so book in advance.

Helsinki, Finland

An 1880s sauna in the Lapinlahti hospital park by the sea, reckoned to be the oldest public sauna still working in Helsinki. Mixed, women's and men's shifts run through the month with no booking: you turn up and pay at the door. The whole sauna can also be hired privately, and the beach is under 100 metres away.

Kustavi, Finland

Separate men's and women's shore saunas at Lootholma, a guest harbour and camping ground on the Kustavi archipelago coast. Wooden terraces run down the rock to a swimming jetty, and the saunas heat morning and evening for berth holders, campers and day visitors alike. Outside those shifts they can be hired privately.

Helsinki, Finland

Helsinki's most architecturally striking public sauna, a timber-lattice building on the Hernesaari waterfront with direct sea access. The smoke sauna and wood-heated sauna sit side by side, both opening onto the Baltic. There is a restaurant on site for afterwards, and it earns the hype.

Espoo, Finland

One of Löylykontti's self-service shore saunas, this one stands on Matinkylä swimming beach in Espoo with a panorama window to the sea. Book a bench place on a shared hour or the whole sauna for your group, then let yourself in with a door code. Swimming runs all year, and the outdoor rinsing shower opens June to September.

Helsinki, Finland

Two container saunas sit on the Sörnäinen shore promenade, with heated steps running from the terrace down into the sea. Book a slot online and let yourself in with a door code, either a shared bench place or the whole sauna for your group. Swimming carries on through the winter.

Rauma, Finland

Three saunas stand on the Fåfänga headland by the sea at Rauma, kept up jointly by a local sports club and the town's trade-union association. One takes twenty bathers, the other two take six. Public shifts alternate with private hire of the saunas and the club room.

Helsinki, Finland

Three wood-fired saunas on the sea at Länsiulapanniemi in Lauttasaari, run by the Helsinki police summer home association but open to anyone.

Helsinki, Finland

A seaside sauna building in the grounds of Hotel Rantapuisto in Vuosaari, with room for fourteen, an electric stove and a terrace looking out over the archipelago.

Helsinki, Finland

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.

Swimming is straight off the deck.

Helsinki, Finland

Two traditional smoke saunas on the northern tip of Vasikkasaari, with the Helsinki skyline across the water.

A boat runs out from the Market Square on summer weekends, and the island is also let for private events.

Helsinki, Finland

A free, volunteer-run sauna on Mustikkamaa, the island park a footbridge away from Kalasatama. No staff, no booking, no rules beyond basic sauna etiquette. Bring your own towel and an open mind: Helsinki at its most democratic.
