ThermaSol Astra 4-Person Indoor Semi-Panoramic Glass Sauna Cabin

Bring contemporary Scandinavian-inspired design and traditional sauna bathing into your home with the ThermaSol Astra 4-Person Indoor Semi-Panoramic Glass Sauna Cabin. Combining natural wood finishes, transparent glazing, and a distinctive corner-style layout, the Astra creates an inviting indoor retreat designed for relaxation and everyday comfort.

Its semi-panoramic glass panels create an open, light-filled appearance, complemented by brushed Tyrol wood paneling and comfortable thermo-aspen benches. The combination of natural materials and clean architectural lines makes the Astra an elegant addition to a dedicated home sauna or indoor wellness space.

A Harvia Virta electric heater provides traditional sauna warmth, while multilayer wood fiber insulation helps retain heat within the cabin. Integrated RGB LED lighting allows you to personalize the interior atmosphere. Designed to accommodate up to four people, the Astra arrives flat-packed for assembly at its intended indoor location.
