Thermo-D Pine Floor Boards (Interior) — 26 x 117 x 3600 mm (per board)

Heavy 26 mm thermo-D pine floorboards, designed specifically for the hot, wet, thermal-cycling reality of a sauna floor. Standard pine warps and cups within a season in these conditions; the extended kiln treatment locks moisture out and gives you a floor that stays flat and true for the long haul.

The tongue-and-groove profile closes tightly against water ingress, and the 26 mm thickness gives a solid, quiet feel underfoot — no bounce, no squeak.
