If You Want a Real Finnish Sauna, It Must Be Built by Those Who Truly Know How

Asoon Rakennus has long experience in designing and building genuine Finnish saunas — elegant, functional, and made to last. We have created a wide range of stylish Scandinavian saunas, from modern minimalism to traditional wood-heated designs, always with authentic Finnish craftsmanship and attention to detail.

What makes a Finnish sauna different? It’s the balance between heat, humidity, ventilation, and materials. The benches are built from selected Nordic wood, the layout supports even steam distribution, and every surface is finished to withstand years of use. A true Finnish sauna is not just a room — it’s an experience of calm, craftsmanship, and comfort that only comes from builders who understand its traditions.

Sauna, private house, Villa K, Kirkkonummi – Sundsberg
This sauna was built with absolute dedication to detail. Notice the floating benches and seating, with steel supports seamlessly embedded into the walls. The large miter-cut tiles are made of genuine stone, complemented by exquisite hardwood finishes and wide bench boards. A truly exceptional place to enjoy the sauna experience.
Sauna, private house, Kirkkonummi – Sundsberg, Nybacka
The goal here was a spacious sauna for at least six bathers to enjoy the soft, gentle steam of an Iki stove. The benches were built from wide, heat-treated alder, giving the sauna its warm tone and elegant Scandinavian feel.
Bathroom, Kirkkonummi – Sundsberg. The Nybacka sauna area was designed with space reserved for a bathtub, currently replaced by a wide washing bench. The soap shelf and all floor surfaces are made of genuine stone.
Sauna, private house in Espoo. Benches and walls made of heat-treated alder, creating a warm and harmonious look.
Private sauna, villa. This log-constructed outdoor sauna was built using high-quality materials. It features two opposing benches and an AITO wood-burning stove that delivers an exceptional, traditional sauna experience.
Sauna in Tammisaari. The walls were tiled with genuine stone, and the corner features an AITO wood-burning stove that provides wonderfully soft steam. The benches are once again made of heat-treated alder.
Why use corner trim on tiled surfaces when the edges can be perfectly miter-cut with a water jet? Few tilers are willing to do this — especially when working with hard natural stone.
