What is SISU?

SISU (pronounced see-su) is more than just a word; it's a profound concept from Finnish culture. Literally translated, it means "inside," but to the Finnish people, it embodies determination, courage, bravery, tenacity, and grit. SISU is about facing obstacles head-on and never giving up, no matter how tough the challenge. It's a way of life that inspires you to pursue an active, healthy lifestyle and make continuous progress toward your goals. With SISU, your actions speak louder than words.

Our Origin Story:

In the wake of the COVID-19 pandemic, two friends, Nick Dadas and Peter Nelson II, found themselves on a morning run in March 2022. They discussed life, family, and business ideas, including their work as wholesalers for saunas and leisure products in Ohio. However, COVID had severely impacted the cedar market, making it challenging to sell their products.


During their run, they decided to dissolve their dealership and create a new kind of sauna experience with the best materials, hand-selected cedar, quick lead times, and made in Ohio. The decision to become manufacturers was not easy, but Nick and Peter were determined. They shared their idea with their now manufacturing partner, Mark, whose family had Finnish roots and a deep connection to sauna culture. Mark was all in.


In June 2022, Nick and Peter had their first working sauna, the "Edwin Barrel," named after Mark's father. On August 1, 2022, SISU Sauna Co. was born, and they sold their first sauna within four days. This was a moment of triumph, confirming they had made the right decision.


Since then, SISU Sauna Co. has shipped handcrafted products across the US, reaching people genuinely invested in their health. These go-getters build their ideal lifestyles around wellness, community, and the desire for more out of life. The name SISU, which means "having an internal drive to persevere, be determined, display courage, go through life with tenacity, and always have grit" in Finnish, reflects the brand's ethos and the resilience of its founders.

The SISU Sauna Co. family wants you to channel your inner SISU, recover faster, and achieve more. By taking care of your body and mind, you can unlock your full potential and live your best life. Through our commitment to quality and excellence, SISU Sauna Co. is more than just a business; it's a way of life.
