ThermaSol Spectra Outdoor Sauna

The Spectra is a compact, design-forward outdoor sauna that blends bold aesthetics with restorative wellness. Its sleek, single-glazed facade—available in natural or black wood—complements any garden setting. It’s a modern statement piece built for all-season use.

Inside, thermo-aspen benches and brushed Tyrol wood walls add warmth and texture, while LED color light therapy lets you shift the mood from calming to invigorating at the touch of a button.

Spectra comes equipped with a 8kW Harvia heater for fast, even heat and gentle steam. Its multi-layer insulated walls, eco-friendly wood fiber insulation, and firestone EPDM weatherproof roof ensure durability and comfort year-round.
