Shop Sauna Accessories ›Sauna Woods — the heart of the build
Your wood choice sets the look, feel and longevity of the room. We stock kiln-dried Western Red Cedar, Nordic Spruce, Alder, and heat-treated Thermo-Aspen and Thermo-Spruce in tongue-&-groove cladding, clear and knotty grades, plus matching bench material and trim. Thermally-modified species resist moisture and warping for decades, while cedar brings its classic aroma and natural rot resistance. Every profile is milled specifically for the heat and humidity of a sauna.
Choosing the right heater
The heater is sized to the room's cubic volume and whether it's indoor or outdoor. We carry electric heaters from 3kW up to commercial units, wood-burning stoves for off-grid cabins, and WiFi-capable digital controllers so you can pre-heat from your phone. Pair any heater with the correct volume of olivine, vulcanite or diabase stones for steady, even löyly. Not sure on size? Our team will spec it for your exact build.
Doors, windows & finishing touches
Sauna doors and windows are built from tempered, dual-pane glass with heat-stable wood frames so they seal tight and stay cool to the touch. Choose clear or tinted glass and a frame species that matches your cladding, then finish the room with LED or Himalayan salt lighting, proper vents, duckboard flooring, foil vapor barrier and food-safe wood oil or wax. Every component we sell is made for the sauna environment — nothing generic.
