Carbon Smart Finnish Sauna Room | 7' x 9'

The Finnish Sauna Builders Carbon Smart™ 7' × 9' × 8' Indoor Sauna Room Kit enters the 10–11KW heater tier — the threshold where the Carbon Smart™ collection achieves its most powerful thermal performance, delivering the heat output that professional spa operators specify for their highest-capacity rooms. At 63 square feet, the 7' × 9' accommodates up to six guests in a space that feels more like a dedicated wellness room than a sauna enclosure — wide enough for genuine freedom of movement, deep enough for a full three-tier bench hierarchy.

Compatible with the Harvia Cilindro 11KW WiFi, Harvia Club 10KW WiFi, Harvia Virta 10.5KW WiFi with railing, and the Harvia Virta Combi 10.5KW WiFi — which adds steam generation to the thermal experience — the 7' × 9' Carbon Smart™ kit offers the most sophisticated heater selection in the collection. Available in Thermo Poplar or Western Red Cedar, with Finnish Sauna Builders' precision construction throughout.
