Experience Koselig
Each Koselig sauna looks different - because each sauna is intentionally designed and built for each unique client.
We’ve converted everything from a closet to a dirt cellar, into to a private spa-like wellness space. We can build in-home or free-standing exterior saunas.
We partner closely with our clients to get to know them, their vision for the sauna space, who they will share the space with and ways to make the space soothing so they will experience koselig each sauna.



Project Spotlights
Wellness Space Sauna
We partnered closely with architect on new-build wellness space to design a sauna to fit in sauna/plunge room in Denton, TX. This sauna was unique using big timbers for benches to contrast the dark walls.
Boat House Sauna
We converted a third of this historic stone boat house on the edge of Balsam Lake, WI into an oasis featuring warm thermally modified aspen, curved ceiling and Finnish fiber optic starlights on a dimmer switch. The size of this sauna warranted two electric IKI stoves to enjoy the lake views.
Dirt Cellar into Spa
Dirt cellar converted into spa-experience sauna featuring black wax cedar walls, basswood benches, custom changing room with a slate water feature, live plant wall and warm lighting.
Corner View Lake Retreat
Backyard spa with a corner window lake view of Diamond Lake in South Minneapolis.
Sauna Spa in 3 Season Porch
We converted a un-used three season porch into a soothing cedar wellness space in Minneapolis.
Lake View Sauna
Aspen sauna in new-build home featuring large picture window with lake views of Gull Lake, Minnesota.
