Thermo-Spruce Sauna Bench and Floor Wood – 5/4 SHP Sauna Wood By Thermory

One of our missions at Sauna Marketplace is to make it more affordable to build a DIY sauna without compromise.  Sauna bench wood has always been a barrier, but this 5/4 SHP Bench profile from Thermory makes it easier than ever. Intense natural modification using heat and steam alters this Nordic Spruce at a cellular level, resulting in a more durable and healthy choice than Western Red Cedar at a fraction of the price.  Unlike WRC, this Thermo-Spruce won’t warp, expand, contract, or cup. Recommended Uses: Sauna benches, backrests, flooring, and skirting.  These 1.0″ thick sauna bench boards are thick enough to build the frame, but we recommend using standard 2x4s for that.  See detail below.
