Koskenniska Smoke Sauna

Koskenniska Smoke Sauna is a high-quality, modern Finnish smoke sauna designed to accommodate even larger groups in comfort and style. This spacious lakeside sauna combines traditional Finnish sauna culture with contemporary architecture and premium facilities, creating a relaxing and authentic experience in the heart of nature.
On the terrace, guests can enjoy two heated outdoor pools, available year-round for sauna visitors. The gentle heat of the smoke sauna, paired with the warmth of the outdoor pools, offers the perfect opportunity to unwind and disconnect from everyday life. For those seeking a true Nordic experience, the lake is accessible for a refreshing swim in both summer and winter — whether you prefer open-water swimming under the midnight sun or an invigorating dip in icy winter conditions.

Facilities for Groups and Private Events

Koskennniska Smoke Sauna is ideal for larger gatherings, corporate groups, celebrations, and private events. The sauna comfortably accommodates up to 30 guests at the same time, while the separate fireplace lounge provides seating for up to 20 people, making it easy to combine sauna bathing with socialising or dining.
In addition to the heated outdoor pools, the facilities include comfortable changing rooms and a private lounge area. For group bookings, towels are included in the price. For groups exceeding 30 people, an additional €5 per person applies.
Located just 150 metres from Varjola’s main building, the smoke sauna is easily accessible while still offering privacy and a peaceful atmosphere by the rapids.

Koskennniska Smoke Sauna represents modern Finnish architectural design while honouring traditional smoke sauna heritage. In 2015, it was among the first saunas awarded the prestigious Authentic Finnish Sauna Experience quality certificate by Sauna from Finland — a recognition of excellence in Finnish sauna culture and service.
