Western Red Cedar Sauna Wood – Built for Heat and Humidity

Western Red Cedar is the gold standard for sauna construction. This isn’t just marketing—it’s biology. The wood contains natural oils that resist moisture and prevent rot. It stays dimensionally stable even when exposed to extreme temperature swings.

Other woods crack under sauna conditions. Pine warps. Hemlock splits. Western Red Cedar handles 180°F heat and high humidity without breaking down. The tongue and groove design ensures boards stay tight even as the wood expands and contracts through heating cycles.

The aromatic oils also matter. They release a pleasant scent when heated and create a naturally antimicrobial environment. You’re not just buying lumber. You’re buying wood that’s engineered by nature for exactly this purpose.

Clear Grade Cedar Planks for Sauna Walls, Benches & Floors

Every sauna application has different requirements. We stock Western Red Cedar lumber for each one:

• Wall and Ceiling Boards: Tongue and groove panels in 1×4 and 1×6 dimensions. Smooth surface, tight fit, aromatic when heated. Creates seamless interior walls that handle moisture.
• Bench Stock: Clear-grade cedar with zero knots. Smooth enough for bare skin contact. Available in 2×4 and wider dimensions for structural bench frames and seating surfaces.
• Flooring: Moisture-resistant cedar decking with natural grip. Handles wet conditions and foot traffic. Won’t splinter or deteriorate like cheaper alternatives.

Clear grade means knot-free wood. No rough spots, no resin pockets, no weak points. This matters for benches where you’re sitting directly on the wood. It matters for walls where knots can become heat spots or structural failures.
