Architectural Design with Functional Detail

 

 

A defining feature of the Fortis is its modern eave roof, designed with a subtle overhang that frames and shelters the glass frontage while enhancing the cabin’s clean-lined silhouette.

 

 

The exterior pairs Nordic thermo-spruce and pinewood cladding, showcasing natural grain textures that blend organically into outdoor environments. This warm wood contrast highlights the sleek front façade constructed from Parsol dark grey tinted glass with aluminum framing.

 

 

Hidden hinges maintain a streamlined look, while integrated coat hooks add thoughtful functionality without disrupting the design.



Insulated for All-Season Comfort

 

 

Inside, the Fortis is built for performance. Multi-layer wood fiber insulation supports energy efficiency and stable interior temperatures, allowing reliable sauna sessions in both cold winters and warm summers.

 

 

Brushed thermo-spruce interior walls introduce depth and texture, complementing the smooth thermo-aspen benches and backrests designed for ergonomic comfort.



Customizable Ambience & Precision Heat

 

 

Recessed RGB LED lighting enhances the mood of each session. Using the included lighting control, bathers can adjust color tones to create a calming or energizing atmosphere.

 

 

For heat performance, the cabin features the Harvia Virta electric heater, paired with the Harvia Xenio control system for accurate temperature management and responsive steam generation.

 

 

The ThermaSol Fortis Sauna Cabin delivers architectural clarity, dependable heat performance, and refined outdoor durability—creating a contemporary sanctuary designed to elevate your wellness ritual in every season.
