Carbon Smart Finnish Sauna Room | 6' x 7'
Choose options
The Finnish Sauna Builders Carbon Smart™ 6' × 7' × 8' Indoor Sauna Room Kit delivers 42 square feet of premium indoor sauna space — a configuration that elevates the home wellness room from family amenity to genuine luxury destination. At this scale, the Carbon Smart™ kit begins to approach the spa-grade sauna experience: enough room for multiple bench levels, enough width for a properly generous upper bench, and enough interior presence to feel unmistakably intentional as a design choice.
With Harvia 8KW compatibility across four heater options — from the classic KIP80B with built-in control to the premium Cilindro PC80E WiFi with full app integration — and available in Thermo Poplar or Western Red Cedar, the 6' × 7' Carbon Smart™ kit is a serious investment in residential wellness infrastructure. Finnish Sauna Builders' reputation as North America's premier sauna manufacturer is backed by decades of installations in luxury homes, boutique hotels, and wellness facilities where performance and longevity are non-negotiable.
