The Koselig Duo

Joyful family behind this dream and business to change communities, one sauna at a time.
Custom sauna builders, Sienna and Joseph Pesta who cofounded Koselig Sauna to help people reconnect with themselves and eachother.

Rooted in commitment

We are a husband-and-wife-duo committed to designing high performance saunas that become a personal oasis for our clients and their community. Our hope is that sauna fosters a deeper connection between people and nature and unlocking all of the great benefits traditional sauna has to offer.

We leverage principles of biophilic design - which incorporates organic materials, natural lighting, earth tones and plants to create a soothing environment that evokes the serenity of nature. The design and materials we use are intentional to soothe your nervous system and foster true rest.

We live on the Mississippi River just north of Minneapolis, MN. We are blessed with a lovely daughter who exudes joy and reminds us to remain curious, admire the beauty around us and be present with those whom we love. We are expecting another bundle of joy in the summer of 2025.

Our favorite part of this work is not only working together, but partnering with our clients. We prioritize the relationship with our clients and hope to stay connected long after the project ends.

We can’t wait to meet you!

“I go to nature to be soothed and healed, and to have my senses put in order.”
