Every piece of wood we carry is chosen specifically for sauna environments. They’re perfectly designed for seamless installation across walls, ceilings, and benches, offering a smooth finish and unique wellness properties. Available options include:
Thermo-Aspen is a premium, thermally modified wood known for its exceptional stability and refined appearance. The heat treatment removes moisture and enhances durability, resulting in a rich golden-brown tone and resistance to warping or decay. With a smooth, splinter-free surface and very low heat conductivity, Thermo-Aspen is extremely comfortable against the skin, even at high temperatures. Resin-free, chemical-free, and eco-friendly, it’s an ideal choice for modern, high-end sauna interiors where longevity and comfort are top priorities.
Best for: Sleek, modern saunas with maximum comfort and long-term stability.
Natural Alder offers classic sauna elegance with a light honey-to-blonde color that deepens beautifully over time. As a stable hardwood, it performs reliably in high heat without warping or cracking. Alder is naturally resin-free, eliminating sap issues, and its smooth surface stays comfortable for seating. Its timeless appearance and proven performance make it a favorite for traditional sauna designs.
Best for: A traditional look with dependable performance and natural warmth.
Hemlock is valued for its strength, clean appearance, and resistance to warping. It features a uniform, knot-free grain that works well in contemporary or minimalist sauna designs. With low heat conductivity, hemlock remains cool to the touch, and its neutral scent makes it ideal for users sensitive to stronger wood aromas. Naturally hypoallergenic and resin-free, it offers a clean, understated sauna experience.
Best for: Modern designs or scent-sensitive users who want a clean, minimal aesthetic.
Thermo-Alder elevates traditional alder through thermal modification, enhancing stability, durability, and moisture resistance. The process creates a rich reddish-brown tone and eliminates resins, preventing sap release or cracking in extreme heat. Smooth to the touch and comfortable for seating, Thermo-Alder also resists rot and decay, making it a low-maintenance option for high-humidity environments.
Best for: A warmer, darker look with enhanced durability and minimal maintenance.
Western Red Cedar is the most iconic sauna wood, prized for its natural aroma and exceptional resistance to moisture and decay. Its natural oils provide durability while also releasing a soothing scent that enhances relaxation. Cedar’s excellent insulation keeps surfaces cool to the touch, and its low expansion rate ensures long-term structural stability. With rich amber and red tones, it delivers both beauty and performance.
Best for: A classic sauna experience with aroma, visual richness, and proven longevity.

Proper installation and ongoing care ensure that your sauna wood will retain its beauty and structural integrity for years to come. Follow these expert guidelines for the best results:
Allow wood to rest in the sauna room for at least 24–48 hours before installation to balance moisture.
Boards can be installed horizontally for traditional appeal or vertically for a modern, height-enhancing look.
Maintain proper airflow behind wall panels to manage condensation and increase longevity.
Wipe with a soft, damp cloth and mild detergent. Avoid oils, varnishes, or harsh chemicals that may seal the wood’s pores.
Check periodically for loose boards, nails, or darkening due to moisture buildup. Lightly sand the wood if necessary to restore a fresh surface.
