Thermally Modified Pine Sauna Wood - Bench Board 5/4x4 SHP is crafted from premium Nordic Pine, thermally modified using only heat and steam for outstanding performance in sauna heat and humidity.

The thermal modification removes natural resins, making it completely safe for skin contact at high temperatures, and significantly improves moisture resistance and dimensional stability.

Nordic Pine's naturally tighter, smaller knots ensure more even thermal conductivity across the bench surface and greater long-term durability compared to Thermo-Spruce bench boards - making it the preferred bench material for both Thermo-Pine and Thermo-Spruce sauna builds.

The thicker 5/4 profile offers added durability and a more substantial feel underfoot compared to standard 1x boards.

Available Lengths: 2–11.8 ft.

This wood is sold in a bundle of 5 boards.

  • Thermally Modified Nordic Pine: Resin-free and splinter-resistant - safe for direct skin contact in high-heat sauna environments. Tighter knots ensure even heat distribution and long bench life.
  • SHP Profile: Smooth on all four sides for a comfortable, splinter-free surface on every face.
  • Dimensionally Stable: Thermal modification significantly reduces wood movement, preventing warping and cupping in sauna heat and humidity.
  • Chemical-Free Treatment: Modified using only heat and steam - no preservatives, chemicals, or adhesives.
  • Versatile Use: Suitable for bench tops, sauna flooring, and decking around cold plunge and wellness areas.
  • Width: 3.62 in
  • Thickness: 1.02 in
  • Coverage: 3.9 in per board
  • Profile: SHP (Smooth 4 sides)
  • Material: Thermally Modified Nordic Pine (ThermoWood®)
