Part of the exclusive Heritage Architectural Series, the Heritage Lux Dolomiti Small is a refined architectural sanctuary crafted for those seeking a bold, fortress-like retreat in a compact footprint. Named after the dramatic Italian mountain range, this 4–6 person retreat features a premium Thermo-Spruce exterior - wood that has been thermally modified to ensure exceptional stability, weather resistance, and enduring beauty.

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 refined 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.

Available in two builds. The standard build is crafted from 44 mm solid wood — walls thick enough to hold heat and carry the character of a traditional outdoor sauna, well suited to temperate climates and relaxed, occasional use. The fully insulated version is one of the few outdoor saunas in its class built with a true multi-layer wall assembly and a dedicated layer of high-performance PIR insulation throughout — across walls, roof, and floor — for faster warm-up and steadier temperatures, ready for frequent use and year-round performance in any climate.
