Light-filled and design forward, the Lumaria Sauna Cabin offers a modern corner friendly layout for interior wellness spaces.
The solarium design is highlighted by the floor-to-ceiling panoramic glass facade that extends the length of the two outer walls. The frameless, flush-mount glass door allows access to the spacious interior with brushed Tyrol wood walls offering tactile comfort and natural elegance.
Thermo-aspen benches and backrests create a unique aesthetic contrast to the walls and ceiling while delivering superior comfort during sauna sessions. Multi-layer wood fiber insulation ensures superior heat retention and efficiency while the Harvia Virta swiftly generates plentiful heat and steam. RGB LED color therapy lighting illuminates from recessed locations throughout the interior, with the included control creating a fully customizable ambiance.
Supported by a 1-year warranty, the ThermaSol Lumaria indoor sauna combines natural materials with lasting performance and energy efficiency for a sauna solarium exemplary for indoor wellness spaces.
Shipping Note
On rare occasions, remote or complex delivery areas may not qualify for free shipping. Indoor saunas are delivered via flatbed trailer with pre-assembled panels and detailed installation instructions. Assembly typically requires two people, basic tools, and a few hours to complete. A licensed electrician must install the heater.
Customers are notified two weeks prior to the scheduled delivery to allow time for preparation. Commercial deliveries require a customer-provided forklift or loading dock for unloading, while residential deliveries include freight-company offloading with threshold delivery at no additional cost; no forklift or loading dock is required.
Please ensure you are fully prepared to receive and unload your sauna in accordance with the instructions provided in your manual.
Indoor models are designed to sit directly on your existing flooring. The surface must be level and water-resistant. Suitable materials include concrete, ceramic tile, vinyl, or laminate. If your current flooring doesn’t meet these requirements, an alternative foundation may be needed.
All indoor sauna units are freestanding and can be disassembled and relocated if necessary.
For complete guidelines, please refer to the product manuals.
