Sauna lumber is specially selected wood designed for the unique heat, moisture, and airflow conditions inside a sauna. Unlike standard construction lumber, sauna-grade wood is chosen for its stability, low resin content, and ability to perform in high-temperature environments.
Cedar Sense offers premium sauna lumber options for lining the interior walls and ceilings of saunas, including cedar, aspen, alder, thermally modified wood, and other specialty species. These woods are commonly used in traditional Finnish saunas, custom indoor saunas, and DIY builds.
