That decision is the eave. The modern eave-style roofline - with its deliberate overhang projecting beyond the front face and sides of the cabin - transforms what would otherwise be a standard rectangular outdoor sauna into something that reads as genuinely architectural. The eave creates a shadow line across the top of the glass front, frames the view from inside, and gives the Fortis a presence in any outdoor setting that is quiet, self-assured, and unmistakably designed. Combined with the contrast of natural Nordic spruce and pinewood exterior against the contemporary 8mm Parsol Dark Grey glass front - and the practical details of hidden hinges and interior coat hooks - the Fortis is a sauna that rewards attention to detail because it was built with the same attention.\u003c\/p\u003e\n\u003ch4\u003eThe eave roofline - one design decision that changes everything\u003c\/h4\u003e\n\u003cp\u003eMost outdoor saunas have a flat roof cap that sits flush with or slightly above the cabin walls. The Fortis is different: its eave-style roofline extends beyond the front face of the cabin as a deliberate architectural overhang, covered in Firestone EPDM and projecting a clean horizontal shadow line across the top of the glass front. This overhang is not structural necessity - it is a design choice. It gives the Fortis a profile that is unmistakably modern when viewed from the side (the clean horizontal line of the eave reads from thirty feet away), while also providing practical overhead protection for the glass front against direct rain and accumulating snow. The Firestone EPDM covering the eave and roof is the same commercial-grade rubber membrane used in the Spectra - UV-stable, cold-flexible, and fully waterproof across decades of use without maintenance or resealing.\u003c\/p\u003e\n\u003ch4\u003eNordic spruce and pinewood exterior - natural two-material character\u003c\/h4\u003e\n\u003cp\u003eWhere the Spectra uses a single exterior material (Tyrol wood panels, applied uniformly), the Fortis uses a combination of thermally modified and brushed Nordic spruce and pinewood - two naturally related Nordic timber species whose grain and texture respond slightly differently to brushing, light, and weathering. The combination creates a subtle variation across the exterior surface that reads as rich and considered rather than repetitive. Both woods are thermally modified - a non-chemical heat and steam treatment that permanently improves moisture resistance, dimensional stability, and rot resistance - and both are brushed to enhance the grain texture and give the exterior surface the refined, tactile quality that is the trademark of the Fortis finish. Against this warm natural wood exterior, the 8mm Parsol Dark Grey glass front reads as a confident contemporary statement - the contrast between the materials is the core of the Fortis design.\u003c\/p\u003e\n\u003ch4\u003eBrushed thermo-spruce interior walls - a different warmth from Tyrol panels\u003c\/h4\u003e\n\u003cp\u003eInside the Fortis, the interior walls are clad in brushed thermally modified spruce panels - different from the Tyrol panels used in the Spectra and other models. Spruce has a more open, linear grain than Tyrol wood, and the brushed finish on the Fortis interior accentuates that grain with a texture that catches light differently than smooth-planed panels. The interior spruce is lighter in tone than the darker exterior, creating a warm transition from the dark glass front to the naturally luminous interior. Thermo-aspen benches and backrests provide the seating - stable, moisture-resistant, and smooth to the touch at any temperature. RGB LED colour light therapy lighting is recessed throughout the interior and adjustable via remote to any point across the full colour spectrum, with warm amber and cool blue as the common session modes. Coat hooks are included inside the cabin - a small but genuinely useful detail that reflects the Fortis design philosophy: every element serves a function, and every function is considered.\u003c\/p\u003e\n\u003ch4\u003e8mm Parsol PSDG glass, aluminum framing with hidden hinges\u003c\/h4\u003e\n\u003cp\u003eThe Fortis glass front uses 8mm Parsol Dark Grey Glass in aluminum framing - with hidden hinges on the door panel. This is a specific detail worth noting: hidden hinges are more complex to install than exposed hinges, but they eliminate the visible hardware that would interrupt the clean line of the door edge. From outside the Fortis, the glass door has no visible hinge protrusion - the door simply appears as a clean panel within the aluminum frame. The 8mm PSDG provides the same dark grey-green tint, solar protection, and diffuse privacy as the thicker Parsol glass used in the Spectra, at a specification appropriate to the Fortis cabin volume and design brief. The 8kW Harvia Virta heater with Wi-Fi is included, sized precisely for the Fortis's 3-4 person cabin volume, with the Harvia app enabling remote preheating from anywhere.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"sl-hook\"\u003eA fully assembled outdoor sauna for 3-4 people - 90\"L x 87\"W x 89\"H, 2,161 lbs.

The eave. The hidden hinges. The two-material exterior. The brushed interior.

This is not a sauna where the natural materials are painted or covered - they are thermally modified, brushed, and allowed to develop their own character over time.
