Thermally-modified spruce wood, also known as heat and steam treated spruce, is a type of lumber that has been treated with high heat and steam. During this natural process, the heat and steam naturally enhances the properties of this popular softwood. The flames and steam alter the overall makeup of the lumber, making it more durable and resistant to the elements in extreme climates such as the cold from it's native Northern Europe.
Crafted from European-native Nordic spruce sauna wood, these saunas are a blend of beauty and tradition. Known for its stability and color from the natural heat and steam process, thermal spruce adds a touch of Scandinavian elegance to any sauna. Our spruce models are built to offer exceptional thermal performance and long-lasting beauty.
