Thermasol Fortis Traditional Outdoor Sauna

Combining contemporary architecture with robust materials, the Fortis Sauna Cabin is a private, light-filled wellness sanctuary. 

The Fortis is highlighted by the modern, eave-style roofline offering a slight overhang which encapsulates the sauna interior. The Nordic thermo-spruce and pinewood exterior features unique natural textures to blend in with the outdoors, a stark contrast with the contemporary glass front. Parsol dark grey glass with aluminum framing adorns front-facing facade, with hidden hinges and coat hooks offering both sleek styling and utility. 

Inside, the Fortis hosts multi-layer wood fiber insulation to keep the interior cozy and energy efficient year-round. Brushed thermo-spruce walls offer a warm, textural contrast in comparison to the sleek thermo-aspen benches and backrests. RGB LED illumination from recessed locations compliment the inviting atmosphere, with an included control to adjust users desired ambiance. Bathing enthusiasts can sit back and enjoy the Harvia Virta's abundant heat and steam through the Harvia Xenio control for year-round sauna sessions.

Supported by a 1-year warranty, the ThermaSol Fortis outdoor sauna delivers powerful performance and refined wellness in a modern, contemporary space.

Shipping costs are determined based on location. Outdoor saunas are delivered via flatbed trailer and fully assembled.

Customers are notified two weeks prior to the scheduled delivery to allow time for preparation. A forklift or crane is required for placement, and a licensed electrician must install the heater. Due to its size and weight, manual offloading is not recommended. Please ensure the proper equipment is available at the time of delivery.

Please ensure you are fully prepared to receive and unload your sauna in accordance with the instructions provided in your manual.

The path from delivery point to placement site must be clear and accessible for equipment. Saunas should be installed on a firm, level surface with slight runoff for drainage—such as concrete, decking, pavers, or compacted gravel.

For complete guidelines, please refer to the product manuals.
