Part of the exclusive Heritage 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 a breathtaking "geode" effect: the dark, charred exterior gives way to a luminous, pristine Aspen interior that feels soft to the touch and remains historically bright. With its vertical "soft cube" design, this sauna maximizes headroom and volume, while the expansive black-tinted glass front dissolves the boundary between you and nature. Fully insulated for year-round US climates, the Stromboli Small offers a private, high-contrast retreat where modern design meets elemental power.
