The Heritage Sauna® Lux Dolomiti Small is a 4–6 person outdoor sauna from the Architectural Series, designed as a bold retreat with a compact 85.4" × 85.4" footprint. Its exterior is built from Thermo-Spruce, a thermally modified wood that resists warping, shrinking and twisting over time. It comes in four stain finishes: Beige, Grey, Teak and Hazel. It is one of the few outdoor saunas in its class built with a true multi-layer wall assembly: the walls, roof and floor use a multi-layer assembly with a dedicated layer of PIR insulation for faster warm-up and steadier temperatures during year-round use.
Inside, chocolate-toned Thermo-Aspen covers the walls, benches and floor with a smooth, resin-free surface that stays cool to the touch. A vertical "soft cube" silhouette maximizes headroom. A large black-tinted tempered glass front connects the interior to the outdoors while maintaining privacy. Under-bench LED lighting adds soft, indirect illumination, and epoxy floor paint seals the sub-floor against moisture. A reversible door and flat-pack delivery make placement and assembly easier in tight or hard-to-access areas. The sauna pairs with an electric heater (sold separately), with 9kW or more recommended.
