Experience koselig {koosh-lee} in your wellness rhythm. We partner with you to design and build a custom sauna that promotes health and fosters connection through Koselig.

Koselig is a custom sauna company based in Minneapolis that designs and builds traditional Finnish saunas through the lens of biophilic design.
Husband & wife duo who started with a shared dream, to create beautiful sauna spaces for people to come, connect and find rest.
Sauna creates the space to connect with yourself and your community.
Integrating cold plunge into sauna experience allows for contrast therapy that can be incredibly beneficial health wise.

We believe in the power of traditional Finnish sauna to promote healthy lives and relationships.

  • We are a husband-wife-duo, dedicated to creating beautiful sauna spaces that foster connection between people and the nature that surrounds us.

  • Koselig is a Norwegian word, similar to Danish Hygge, that encompasses what we believe sauna should accomplish: the feeling of wellbeing in a warm atmosphere amongst companions and nature.

    We build saunas that support your health and bring people together. We want your sauna to not only be apart of your daily rhythm, but something you want to share with others as well.

  • We work closely with our clients to understand their life rhythms to align with their lifestyle and ignite a deep love for sauna.

    We appreciate the opportunity to get to know our clients over the duration of the project through initial vision, design meetings and the build. Our favorite way to end the project is to share a sauna together.

  • Most importantly, we take the time to listen to your vision and preferences.

    We want to build a sauna you look forward to using everyday and are proud to share with others.

    By leveraging biophilic design and focusing on the details that matter most to you, we can create a space for rest, healing and health.
