Transform your home into a private wellness retreat with the Carbon Smart™ Indoor Sauna Room Kit. Designed for both homeowners and professional installers, this complete sauna package provides everything needed to create an authentic, spa-quality sauna experience within your space.
Complete Sauna Kit
Each Carbon Smart™ indoor sauna kit arrives with all interior components precisely cut and tailored to your room dimensions for a streamlined installation process. Simply provide the framing, insulation, electrical wiring, and exterior wall finish — we supply the rest.
Creating a custom sauna experience has never been more accessible.
Premium Thermo Poplar Wood
Carbon Smart™ saunas are crafted exclusively from sustainably sourced Thermo Poplar, a thermally modified wood selected for both its exceptional durability and refined natural aesthetic.
Thermo Poplar undergoes a specialized thermal modification process at approximately 374°F, enhancing dimensional stability while improving resistance to humidity and temperature fluctuations — all without the use of chemicals.
The result is a warm, sophisticated wood finish ideal for creating a naturally beautiful, long-lasting sauna environment. As part of the Carbon Smart™ collection, the wood is responsibly sourced to support carbon-smart forestry practices.

Note: Your sauna shipment will include an all-glass door, though some photos may display a glass wall for reference. Backrests are shipped flat; if you'd like an angled backrest, additional spacers can be easily created on-site to achieve your desired pitch.
Note: Wall boards run in the standard horizontal direction unless room width exceeds 8 ft; in such cases, an interior seam will be added where two boards meet to span the width.
