A complete interior sauna kit built for a room you're already framing — Thermo Poplar wood, precision-cut to your dimensions, with everything needed to finish the interior once your walls, insulation, and wiring are in place.

Right For You If…

  • You're building a sauna into an existing or planned room and need the interior components, not a standalone structure
  • You're comfortable with (or hiring for) framing, insulation, and electrical work, and want the interior finish handled by a dedicated kit
  • You want wood specifically modified for sauna humidity and heat conditions rather than standard lumber

What Makes It Worth It

  • Thermo Poplar wood, thermally modified at approximately 374°F — chemical-free process for improved humidity and heat resistance, plus a warm, rich tone
  • Precision-cut to your room's dimensions — components arrive ready to install rather than requiring on-site cutting
  • Customizable bench configuration — choose the layout that fits your space
  • Complete finishing kit — includes wall and ceiling boards, bench boards, corner moldings, duckboard flooring, vent grills, all-glass door, sauna bucket and ladle, thermometer, headrest, and a vapor-proof light
  • Responsibly sourced wood — part of a carbon-conscious forestry sourcing line
