The ThermaSol Lumaria is a 2–5 person indoor glass sauna cabin designed for home installation. It is built for buyers who want a full-size, visually open sauna that fits into a corner without requiring a dedicated sauna room. The floor-to-ceiling panoramic glass facade and brushed Tyrol wood paneling are the two primary differentiators at this price point.
Why This Indoor Glass Sauna Cabin
Built for open-plan home spaces — the floor-to-ceiling panoramic glass facade creates a visually open layout that installs into a corner without requiring a dedicated enclosed room.
Built for consistent heat retention — multi-layer wood fiber insulation works with the Harvia Virta heater to maintain cabin temperature efficiently across sessions.
Built for two to five users — available in Medium and Large sizes; thermo aspen benches are moisture-resistant and sized for group use.
Built for ambiance control — recessed RGB LED color lighting lets you adjust the visual environment of each session.
Built for straightforward setup — arrives flat-packed; no permanent construction required beyond electrical connection.
