The PROSAUNAS Thermo-Spruce 1x4 STS4 cladding brings a modern edge to traditional sauna design. Its narrow, angular grooves create a sleek nickel-gap look, adding depth and contrast to walls and ceilings. With a rich amber tone and natural knotty texture, Thermo-Spruce combines rustic warmth with contemporary Scandinavian style.

Through a natural thermal modification process using only heat, steam, and pressure, the wood gains enhanced durability, moisture resistance, and stability. Perfect for high-heat environments, it resists warping and decay while maintaining its elegant finish—an ideal, eco-friendly choice for refined sauna interiors.
