Part of the exclusive Heritage Sauna® Architectural Series, the Heritage Lux Stromboli Large is a commanding architectural masterpiece, expanded to accommodate families and social gatherings without compromising its fortress-like mystique. Named after the volcanic Mediterranean isle, this 6–8 person sanctuary 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 arresting.

Stepping inside reveals the most exclusive element of this architectural sauna: a luminous, pristine Aspen interior that feels soft to the touch and remains historically bright. This creates a breathtaking “geode” effect as the dark, charred exterior opens into a radiant inner sanctuary. Designed with a vertical “soft cube” silhouette, it maximizes headroom and volume, while the expansive black-tinted glass front dissolves the boundary between you and the outdoors.

The fully insulated sauna 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.

Perfect for year-round US climates, the Stromboli Large offers a spacious, high-contrast retreat where modern design meets elemental power.

  • Architectural series design – Part of a flagship collection with bold geometric styling and premium construction, delivering a visually striking outdoor sauna that blends modern luxury with durable, weather-resistant performance for long-term residential enjoyment.
  • Yakisugi exterior protection – Traditional Shou Sugi Ban charring process creates a hydrophobic, insect-resistant, and fire-retardant exterior without chemical sealants, offering long-lasting durability while maintaining a distinctive, low-maintenance architectural finish.
  • Geode effect interior – Bright Aspen interior contrasts dramatically with the dark exterior shell, creating a visually stunning, light-filled environment that feels inviting and comfortable while offering smooth, cool-touch surfaces for an elevated sauna experience.
  • Panoramic glass experience – Expansive black-tinted tempered glass panel allows natural light to fill the space while preserving privacy, delivering an immersive open-wall effect that enhances relaxation and connects your sauna session to the outdoors.
  • Construction – Fully insulated Multi-layer walls, roof, and floor with a dedicated layer of high-performance PIR insulation. Faster warm-up, more stable temperatures, lower running costs — built for frequent use and year-round performance.
  • Spacious social capacity – Generous interior layout accommodates 6–8 adults comfortably, providing ample room for group relaxation, stretching, or hosting guests, making it an ideal centerpiece for family wellness and social gatherings.
  • Integrated LED ambiance – Under-bench LED lighting casts a soft, warm glow that enhances visibility and creates a calming, sophisticated atmosphere, elevating the overall sauna experience without the need for additional lighting installations.
  • Moisture protection system – Includes epoxy floor paint for sub-floor sealing, forming an impermeable barrier that protects against moisture intrusion, reduces long-term wear, and helps extend the lifespan of your outdoor sauna installation.
  • Flexible installation design – Reversible door configuration and flat-pack delivery allow easier setup in tight or hard-to-access spaces, giving you greater control when positioning the sauna within your backyard or patio layout.
  • Warranty coverage – Residential use includes 3-year coverage on the sauna cabin and structural components, plus 1-year coverage on included cabin accessories. Commercial use provides 1-year coverage on all cabin components. Heaters are sold separately and covered under the manufacturer's own warranty.
