Building a sauna in the Treasure Valley? GH Sales Lumber & Flooring carries Japanese Sugi cedar 1x6 tongue and groove that's a great fit for sauna walls and ceilings, plus Sugi 2x4, 5/4x6 and 2x6 boards for benches, framing details and trim. Everything is at our Nampa location, so you can see and handle the boards before you buy.
Our 1x6 Sugi tongue and groove is planed smooth on both faces, with a V-groove on one side and a square-edge nickel-gap look on the other, so you can choose the look you want. Each board covers about 5 in. of wall once installed.
From a room in progress to a finished build, here's how the 1x6 Sugi tongue and groove looks on sauna walls and ceilings. Tap a photo to see it larger.

See photos and details →Sugi (Cryptomeria japonica) is often called Japanese cedar. Botanically it isn't a true cedar; like western red cedar, it belongs to the cypress family. It has been used in Japanese building for centuries. Curious how it compares? Read our Sugi vs. western red cedar guide.
The 1x6 tongue and groove is the board for the walls and ceiling. Most builders install it over a vapor barrier on the warm side of the insulation, and blind-nail through the tongue so fasteners stay hidden. Not sure how much you need? Use our sauna wood calculator to estimate square feet, linear feet and cost.
For benches, many builders use thicker boards for the seat slats and frame. Our Sugi 2x4 and 5/4x6 (a true 1 in. thick) are worth a look. Leave small gaps between slats, round over the edges and keep metal fasteners out of the sitting surface so nothing gets hot against your skin.
Many sauna builders leave interior wood unfinished, or use a product made specifically for sauna interiors. Avoid varnish or other film finishes on benches. Follow the finish maker's directions.
