The Author: Wojciech Kumik

I am an architect with a passion for small-scale projects. In 2020, together with my father, we built our first sauna, Sauna Tuula, which quickly gained popularity within online sauna communities for its aesthetics. This experience inspired me to help others build their own saunas by creating detailed sauna plans and sharing my expertise.

The Sauna Tuula design was recognized as one of the TOP 3 designs in the Small Architecture category of the Good Design 2022 Competition.
