Bespoke Finnish Traditional Sauna Room | 7' x 9'
Choose options
The Finnish Sauna Builders Custom Indoor Sauna Room Kit in 7' × 9' × 8' reaches the 10–11KW heater tier — the pinnacle of thermal performance in the Custom Indoor collection, and the specification level that professional spa operators and luxury wellness architects specify for their most prestigious cedar sauna installations. At 63 square feet of Western Red Cedar, this room is defined not by its capacity to accommodate people but by the quality of the experience it provides for every person inside it: generous, unhurried, and immersive in every sense.
The heater options at this size are the most sophisticated in the Custom Indoor collection: the Harvia Virta Combi 10.5KW WiFi, which adds integrated steam generation to the full sauna heat experience; the Cilindro 11KW WiFi, the most powerful Harvia heater available in this collection; and the Harvia Club 10KW WiFi, a wide-format heater whose visual weight matches the scale of a 7' × 9' cedar room. Finnish Sauna Builders' construction at this level reflects the investment: cedar selected at the highest grade, installation executed to the tightest tolerances, and every custom detail specified to stand apart.
