The Heritage Sauna® Lux Dolomiti Large is a 6–8 person outdoor sauna from the Architectural Series, sized for families and social gatherings. Its exterior is built from Thermo-Spruce, a thermally modified wood that resists warping, shrinking and cracking through changing seasons. 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 broad black-tinted tempered glass front connects the interior to the outdoors while maintaining privacy. Under-bench LED lighting adds soft, indirect illumination, black bitumen tiles finish the roof, and epoxy floor paint seals the sub-floor against moisture. The sauna ships flat-packed for on-site assembly and pairs with an electric heater (sold separately), with 9kW or more recommended.
