How much does a public sauna cost
The price difference between a traditional neighbourhood sauna and an experience sauna is large. The adult prices below were checked from the saunas' own websites in October 2026. Prices may change, so check them before you go.
Rajaportin sauna in Pispala, Tampere, says it is Finland's oldest public sauna still in operation: bathers are known to have enjoyed its steam since 1906, and the current stone building dates from 1915.
- Rajaportin sauna, Tampere: mixed sauna fee 8 €
- Kotiharju Sauna, Helsinki: €16, discount €13, ages 12–16 €9
- Kulttuurisauna, Helsinki: €17 / 90 min, concession €13
- Allas Sea Pool, Helsinki: 19 € on weekdays and 24 € at weekends, ticket for 2 hours
- Löyly, Helsinki: 29 € / 2 h, extra hour 12 €
What the price includes
In traditional saunas you often pay for the sauna alone and rent a towel separately. At Kotiharju sauna, towel hire is 4 € and the washing service 15 €; the washer is present on Thursdays and Saturdays. The two-hour löyly price includes a towel, a seat cover, shampoo and shower soap.
Bring your own towel, seat towel and water bottle to Kulttuurisauna. An Allas Sea Pool ticket includes the chosen time in the pools and saunas. If you go often, ask about multi-visit cards: for example, at Kotiharju a 10-visit card costs €140 and at Kulttuurisauna a seven-visit card costs €77.
Do you have to book a slot
No booking is needed for Kotiharju's public sauna. The evening sessions at the Kulttuurisauna from Wednesday to Sunday must be booked in advance, but you can come to the morning sessions from Friday to Sunday without a booking. Löyly recommends booking, and cancellations must be made at least 24 hours in advance. Weekend tickets to Allas Sea Pool can sell out, and a ticket bought in advance cannot be exchanged or cancelled.
Payment methods vary: for example, cash is not accepted at Kulttuurisauna, and at Löyly, paying with a gift card must be agreed by email.
Mixed sauna, swimwear and other rules
Rules vary by sauna. At Löyly the saunas and public areas are shared, so swimwear is required at all times. At Kotiharju the men's and women's saunas are on different floors. In Rajaportti's Thursday mixed sauna the changing rooms and benches are shared, and you may keep your swimwear on or take it off.
Kulttuurisauna does not accept groups, and a party of more than two people counts as a group. Friday evenings are quiet sauna sessions there. The wood-fired stoves at Kotiharju are single-heat stoves, so adding wood during a session is prohibited.
Sauna etiquette for first-timers
Wash before going into the sauna room and bring a seat cover or towel if the sauna does not provide one. Ask on the benches before throwing more löyly, since not everyone wants it as hot. In quiet sessions, such as the Friday evenings at Kulttuurisauna, only what is necessary is said. Glass bottles and your own alcoholic drinks are not allowed in most saunas.
Allow time for cooling off as well. At seaside saunas you can often swim, but at Löyly, for example, swimming in the sea depends on weather conditions. When going to an ice hole, remember that a hole cut in the ice must be clearly marked, and people with heart conditions should avoid moving straight from a hot sauna into cold water.
Safe sauna bathing
According to the Duodecim Medical Book, you sweat half a litre to a litre per sauna session, so drink water between rounds of steam. Warning signs of fainting are nausea, dizziness and weak knees; lie down immediately if you notice them. According to Terveyskylä guidance, people with heart conditions should sauna in moderation at a temperature below 80 degrees and avoid sudden temperature changes, such as going straight into an ice-hole.
A child tolerates heat less well than an adult. Sauna with a child on the child's terms, and never leave a child alone in the sauna. Water or another non-alcoholic drink is suitable for drinking.
