ThermaSol stripped the indoor sauna down to its essential elements, crisp brushed Tyrol wood, transparent semi-panoramic glass, and a clean architectural silhouette, without sacrificing any of the performance. The result is a sauna that feels less like a fixture and more like a piece of considered design.\u003c\/p\u003e\n\u003ch4\u003eWhere minimalism meets tranquility\u003c\/h4\u003e\n\u003cp\u003eThe Astra's brushed Tyrol wood panels encapsulate a corner-friendly layout, while the transparent glass walls open the interior up to natural light. Inside, the recessed wall supports give the benches a \"floating\" appearance, no floor legs, no visual clutter, and easier cleaning underneath. It's a small detail that completely changes how the space feels in everyday use.\u003c\/p\u003e\n\u003ch4\u003eMaterials that hold up to daily heat\u003c\/h4\u003e\n\u003cp\u003eThermo-aspen benches and arched backrests are knot-free and stay cool to the touch even at peak temperature, so longer sessions never become uncomfortable. Multi-layer wood fiber insulation runs throughout the structure for superior heat retention and predictable energy use. The frameless flush-mount glass door completes the look, clean lines outside, full thermal seal inside.\u003c\/p\u003e\n\u003ch4\u003ePerformance that backs up the design\u003c\/h4\u003e\n\u003cp\u003eThe Harvia Virta 9kW electric heater is the heart of the Astra, paired with the CX45 digital control with Wi-Fi for precise temperature and timing. Start your sauna from your phone via the MyHarvia app, heat will be ready when you walk in. RGB color therapy LEDs are recessed throughout the cabin with a dedicated control, letting you adapt the lighting to match every mood, from focused white to warm amber.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c!-- HOOK SUMMARY --\u003e\n\u003cdiv class=\"sl-hook\"\u003eWhere minimalism meets tranquility, the Astra blends crisp brushed Tyrol wood, semi-panoramic glass, and a 9kW Harvia heater into a corner-friendly sauna built for up to 4 people.
