Stepping inside reveals the most exclusive feature of this architectural sauna: a rich, chocolate-toned Thermo-Aspen interior that offers a velvet-soft touch and stays cool against the skin. This creates a sophisticated, moody ambiance as the Thermo-Spruce exterior transitions into a deeply immersive wellness environment. Designed with a vertical “soft cube” silhouette, this sauna maximizes headroom and volume, while the expansive black-tinted glass front dissolves the boundary between the bather and the outdoors. Fully insulated and enhanced by the thermal properties of the wood, the Dolomiti Large offers a spacious, high-performance wellness retreat suited for year-round use.

Part of the exclusive Heritage Architectural Series, the Heritage Lux Dolomiti Large is a refined architectural sanctuary, expanded to accommodate families and social gatherings while embodying the resilience of the alpine landscape. Named after the dramatic Italian mountain range, this 6–8 person retreat features a premium Thermo-Spruce exterior—wood that has been thermally modified to ensure exceptional stability, weather resistance, and enduring beauty without the use of harsh chemicals.
