Uunisaari sauna – Unwind in the warmth of a sauna by the sea

The Uunisaari sauna is the perfect place to relax and enjoy the sea. Our sauna is located right on the seashore, and in its soft baths you will experience the peace of the archipelago at its best. You can take a dip in the sea water to cool off after your sauna, or enjoy yourself on the sauna terrace admiring the sea. During the winter you can take a dip in the ice hole after sauna for the full Finnish experience.

There are private and public sauna shifts available, and sauna hire is also ideal for private events such as bachelor parties, birthdays or corporate dinners. Our two saunas, the Big and the Little Sauna, are ideal for small and large groups alike.
