Finnish Sauna Builders Carbon Smart Sauna Kit - 7 × 7 × 8 ft

The Finnish Sauna Builders Carbon Smart sauna room kit supplies pre-cut interior components for a 7 × 7 × 8-foot room. Thermo Poplar boards and configurable benches create a coordinated interior for an indoor sauna installation.

Why This Product Stands Out

• Thermally modified Poplar construction.
• Pre-cut interior boards and matching trim.
• Configurable 20-inch-deep benches.
• All-glass door and sauna accessories.

Who This Is For

For homeowners or contractors fitting out an indoor sauna room, with framing, insulation, electrical wiring and exterior wall covering supplied separately.

Key Features

• Thermo Poplar: Chemical-free thermal modification at approximately 374°F improves dimensional stability and resistance to humidity and temperature changes.
• Interior components: Includes foil vapor barrier, 1 × 4 tongue-and-groove wall and ceiling boards, clear bench boards with supports, backrests, matching corner moldings and duckboard flooring.
• Bench layouts: Select a configuration with 20-inch-deep benches in matching Thermo Poplar.
• Door and ventilation: Includes an all-glass door with wood handles and trim, plus upper and lower vent grills.
• Accessories: A bucket with liner and ladle, thermometer, headrest, marine-grade wall-mounted vapor-proof light and installation instructions complete the interior kit.
