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.

We are dedicated to the details.

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.

Cozy living room with large windows showing snow outside, featuring a wooden sofa with patterned cushions, a wooden coffee table, stone and wood wall accents, and a glass door leading to what appears to be a sauna or small room with wooden panels.

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.
