The ThermaSol Spectra is a modern outdoor sauna for 3 to 4 people, built for all-season use. Thermally modified Tyrol panel walls inside and out, thermally modified aspen benches and a vivid thermal glass front in black aluminum framing make it a statement piece for the yard.

Heat comes from an 8kW Harvia Virta heater with Wi-Fi for fast, even heat and soft steam when you add water to the stones. Multi-layer insulated walls with wood fiber insulation and an EPDM weatherproof roof are designed to keep the heat in through the seasons.

A backyard sauna works best when the path to it is easy. Think about a short, well-lit walk from the house, a place to hang towels, and somewhere to cool down between rounds, whether that is an outdoor shower, a cold plunge or simply a bench in the fresh air.
