A warm meeting place for everyone
A wood-fired, self-service sauna at Steinneset, at the far end of Os harbour. You light the stove yourself, and the sea is right outside the door.

Five to eight sessions every day
The morning session is the longest, because the sauna is cold then and you light it yourself. Later in the day it is usually still warm, and the session is shorter. Firewood is included.
Firewood is included in the price. It is waiting in the chest in the changing room. Booking and payment are handled by Periode.

What it costs
You pay per place, and firewood is included. A place costs a little more at weekends.

Good to know before you come
The sauna is self-service, so most of it takes care of itself. These are the things guests ask us most often.
Is the sauna warm when I arrive?
The sauna is self-lit, so it depends on the session. The morning session (08.00, weekends 06.00) starts with a cold sauna, and you light it yourself. Later in the day it is usually still warm from the session before. The front page shows how warm it is in the sauna right now.
What should I bring?
A towel to sit on, swimwear and something to drink. Firewood is included in the price and waiting in the chest in the changing room.
How many places are there?
Ten places in each session. You can book one place in a shared session and share the sauna with others, or book the whole sauna for a fixed price and have it to yourselves. Both apply to the same session.
Where is the sauna, and where do I park?
At Steinneset, at the far end of Os harbour in Osøyro. It is about a 30-metre walk from the car park.
How do I get in?
You receive a code by email once you have booked. The code opens the code lock on the door and is valid for your session. If the code does not arrive, check your junk mail or ask us.
How long does it take to heat up?
A cold stove needs time, which is why the morning session is three hours against two later in the day.
Run by Os Turnforening
Os Sauna is a social and health-giving offer at Steinneset. Os Turnforening runs the sauna on a voluntary basis, and the aim is simple: to make it easier for everyone, whatever their age, shape or background, to look after both body and mind.
The money from every visit goes to sport for children and young people in Os. In 2025 it went, among other things, to the new clubhouse and changing rooms at Kuventræ, and to the inclusion fund that makes sure nobody is left out of sport for financial reasons.
