Sauna wood in stock

Every board here — ProSaunas and Thermory wall cladding, bench stock, trim, and prebuilt bench modules — is milled for sauna interiors and confirmed against live U.S. warehouse inventory by SaunaMarketplace as of July 8, 2026. Filter by what you're building, the color you want, and price per linear foot. SaunaMarketplace also cuts free samples if you want to see a species before committing.

Light & pale

Aspen, Hemlock, Spruce

The traditional Finnish look — bright, low-scent, knot-free boards that keep a hot room feeling airy.

Warm & golden

Alder, Western Red Cedar

Honey and amber tones with more grain character. Cedar adds the classic sauna aroma.

Rich brown

Thermo-Aspen, Thermo-Alder, Thermo-Spruce, Thermo-Magnolia

Thermally modified boards — kiln-baked for stability and rot resistance, with a deep caramel color. The most popular modern interior.

Dark & dramatic

Dark Thermo-Alder, brushed black finishes

Espresso-to-black boards for moody, high-contrast rooms.

Boards are priced per linear foot; availability is confirmed against live warehouse inventory by SaunaMarketplace.

Benches

SHP bench boards with rounded edges, cool to the touch against bare skin. Aspen, alder, and thermo-woods are the classics; cedar for aroma.

Corner trim, door casing, T-moulding, and skirting in matching species, so the details disappear into the room.

Framing lumber (2×4 studs) and bench structure are standard construction-store items — the specialty wood above is what actually touches the heat. Planning help is the SaunaMarketplace team's daily bread.
