Fanatical About Saunas

Fanatical About Saunas

SaunaLife was founded by a passionate group of sauna enthusiasts committed to sharing their knowledge of its life-changing benefits, who dedicated themselves to growing awareness of sauna bathing in North America.

In recent years, the cost of material and labor to create a quality home sauna have become prohibitive for many. The challenge to reverse this trend has become SaunaLife’s mission.

For the answer, our Product Development Team traveled to the birthplace of sauna to understand how Scandinavian materials, designs, and construction techniques could help our cause. We found a kindred spirit and a wealth of knowledge. Now, in collaboration with these Nordic innovators, SaunaLife designs and engineers superior DIY spaces in the spirit of their “sauna way.”

The result? SaunaLife indoor and outdoor saunas are constructed with beautiful woods from Northern Europe that embody Scandinavian heritage and craft. Our wooden materials are sustainably sourced, more durable, and lower in price. Our tireless efforts have significantly reduced construction time and costs, while improving quality.

SaunaLife cultivates partnerships with the nation’s most respected Sauna Resellers and Sauna Constructors to market and install our amazing indoor and outdoor sauna environments.
