Part of the exclusive Heritage Sauna® Architectural Series, the Heritage Lux Stromboli Small is a striking architectural statement designed for those who seek a bold, fortress-like sanctuary in their backyard. Named after the active volcanic island in the Mediterranean, this 4–6 person retreat features a dramatic "Shou Sugi Ban" exterior - an ancient Japanese technique of charring wood to create a deep, obsidian finish that is naturally weather-resistant and visually commanding.
Stepping inside reveals the most exclusive feature of this sauna: a luminous, pristine Aspen interior that feels soft to the touch and remains historically bright. This interior creates a breathtaking “geode” effect as it contrasts with the dark, charred exterior, all within the vertical “soft cube” design that maximizes headroom and volume. The expansive black-tinted glass front dissolves the boundary between you and nature, while the sauna remains fully insulated for year-round US climates - offering a private, high-contrast retreat where modern design meets elemental power.
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.
