Collection: Mod Series

One system. Endless ways to sauna.

Meet the Mod Series — modular saunas designed to fit your space, your style, and how you sauna. Choose Mod4 or Mod6, electric or wood-fired, indoor or outdoor, with modern or traditional exteriors and social or athletic benching layouts to suit how you use your sauna. Built from rot-resistant Thermory wood and insulated with natural sheep’s wool for up to 4× the R-value of traditional saunas, the Mod Series delivers high-performance heat, simple installation, and timeless design.

Precision-Built. Patented to Perform.

The Mod Series is engineered with patented, precision-milled joinery that allows each component to fit together like a glove. Instead of relying on hundreds—or even thousands—of fasteners like typical prefab saunas, our proprietary wood-to-wood connections do the work, requiring only a small, intentional set of hardware. The result is faster assembly, tighter tolerances, and a structure that feels custom-built, not prefabricated.
