Light-filled and design-forward, the ThermaSol Lumaria Indoor Sauna Cabin brings traditional sauna bathing into modern interior wellness spaces. Its corner-friendly solarium design combines floor-to-ceiling panoramic glass, brushed Tyrol wood cladding, thermo-aspen seating, full-spectrum recessed LED lighting, and a powerful Harvia sauna system.
The expansive glass façade extends across both outer walls, creating a bright, open environment that complements contemporary homes, fitness rooms, spas, and boutique wellness settings. A frameless, flush-mount glass door provides access to the spacious interior, while the contrast between the Tyrol wood walls and thermo-aspen benches creates a distinctive, architectural appearance.
Multi-layer wood-fiber insulation supports efficient heat retention, and the included Harvia Virta 9 kW electric sauna heater delivers strong, evenly distributed heat. The Harvia Xenio CX45 Wi-Fi control allows users to adjust time and temperature, create repeat schedules, and manage compatible functions through the MyHarvia mobile app.

Choose the Right Lumaria Size
The ThermaSol Lumaria is offered in Medium and Large configurations. Both models share the same 86.6-inch width and 83-inch height. The primary difference is depth, interior floor area, and recommended seating capacity.
- Width: 86.6 in
- Depth: 66.9 in
- Height: 83 in
- Unit weight: 1,323 lb
- Shipping weight: 1,543 lb
Best for indoor wellness spaces where depth is limited or the sauna will usually be used by one to three people.
- Width: 86.6 in
- Depth: 86.6 in
- Height: 83 in
- Unit weight: 1,543 lb
- Shipping weight: 1,764 lb
Best for buyers who want a larger, square interior with additional seating room for shared sauna sessions.
Why the Lumaria Stands Out
The Lumaria Sauna Experience
A brighter approach to traditional sauna: The panoramic glass façade allows the sauna to feel connected to the surrounding room rather than enclosed or visually heavy.
Natural materials and tactile comfort: Brushed Tyrol wood cladding provides texture and warmth, while thermo-aspen benches and backrests create a smooth and comfortable bathing surface.
Traditional heat and steam: The Harvia Virta electric heater warms the room and stones for an authentic high-heat sauna experience. Water may be applied to the heated stones as permitted by the heater instructions to create bursts of steam.
Personalized lighting: Full-spectrum recessed LED lighting adds a customizable visual atmosphere without distracting from the natural materials and contemporary architecture.
Connected control: The Xenio control and MyHarvia app provide convenient access to compatible sauna timing, scheduling, and temperature functions.
