Description
The ThermaSol Spectra is a fully assembled outdoor sauna cabin for 3 to 4 people, with a full Parsol dark grey glass front set into thermally modified Tyrol wood walls. It heats with a Harvia Virta 8 kW electric heater controlled by a Harvia Xenio CX45 panel with Wi-Fi.
Build
The front is single-glazed 34 mm Parsol dark grey thermal glass in a black aluminum frame. The rest of the exterior is thermally modified Tyrol wood, under a Firestone EPDM roof. Multi-layer STEICO wood fiber insulation helps hold heat. Inside are thermo-aspen benches and backrests, 24 inches deep, and RGB LED lighting. It arrives pre-wired.
Size and siting
The cabin measures 82 x 90 x 91 inches and weighs 2,205 lb, so plan a level, solid base and a clear delivery route.
