The Finnish Sauna Builders Carbon Smart™ 4' × 6' × 8' Indoor Sauna Room Kit is the first configuration in the collection to step into 6KW heater territory — a meaningful performance threshold that signals genuine two-person sauna capability with the heat output to match. At 24 square feet of interior floor space, this kit is equally at home in a dedicated home sauna room as it is in a luxury bathroom upgrade, bringing authentic Finnish sauna heat to residences that demand premium performance in every room.
Available in Thermo Poplar or Western Red Cedar, the 4' × 6' Carbon Smart™ kit is compatible with the full Harvia 6KW range — including the Harvia KIP60W WiFi, KIP60B with built-in control, Cilindro PC60, and the Cilindro PC60E WiFi — providing a heater selection that spans from classic built-in control to the most advanced app-integrated sauna heating on the market.
