Carbon Smart Saunas - 5' x 5' x 8' - by Finnish Sauna Builders

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 working with a smaller footprint and want a compact sauna interior sized to fit
• 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
