How does delivery work?

This sauna arrives fully assembled and ships on a large, secure pallet via LTL freight. Because of its size and weight, you will need to arrange a crane or forklift to move the sauna from the curb to its final location on your property.

Our team will contact you before delivery to review all logistics, answer questions, and ensure you’re fully prepared for a smooth drop-off.

The carrier will reach out to schedule a convenient delivery window, and tracking updates will be provided throughout the process. Protective packaging is included to help ensure your sauna arrives in perfect condition.

What are the electrical requirements?

Thermasol saunas require a 220–240V hardwired connection with a dedicated breaker. Dedicated 120V is also required for accessories such as lighting and controls.  We recommend confirming the exact amperage and wire size with your electrician based on the heater model.

How is the sauna built?

The ThermaSol Fortis Sauna Cabin is built using an insulated outdoor-ready structure with thermally modified Nordic spruce and pinewood exterior finishes paired with thermo-aspen interior seating. Multi-layer wood fiber insulation improves heat retention and energy efficiency, while the dark grey Parsol glass front creates a modern and private outdoor sauna environment. The sauna arrives fully assembled for simplified installation

What are the dimensions?

Exterior Dimensions: 90”L x 87”W x 89”H

What is the warranty?

Every Thermasol sauna is protected by a 1-year warranty covering the cabin structure and non-electrical components.

Heater warranties are provided directly by the manufacturer and vary by brand:

Harvia: 2 years residential warranty

HUUM: Limited 3-year residential warranty (excluding heating elements)

Saunum: 2 years residential warranty

Description

ThermaSol Fortis Outdoor Sauna Cabin

The ThermaSol Fortis Outdoor Sauna Cabin is a masterfully realized architectural sanctuary engineered to bring an elite, premium day-spa experience directly into your backyard landscape, patio, or custom garden setup. Artfully tailored with a balanced footprint that comfortably hosts 3 to 4 bathers, this heavy-duty freestanding cabin serves as a striking geometric focal point for any modern residence. Its exterior architecture features an elegant, minimalist eave-style roofline wrapped in high-end thermally modified and brushed Nordic Spruce/Pinewood, built to withstand the elements beautifully. Inside, the cabin is clad in exceptionally smooth, thermally modified Aspen benches and brushed wood panels, a sophisticated harmony of natural textures that radiates a deep, organic warmth and premium tactile comfort.

The defining visual highlight of the Fortis is its expansive, full-height dark grey glass front. Crafted from premium 8mm Parsol Dark Grey Glass (PSDG), this sleek facade allows natural light to filter inside while strictly preserving absolute personal privacy from the outside, creating a serene and deeply private outdoor sanctuary. To fully engage your senses and support deep physical recovery, the interior features an integrated RGB LED color therapy system. This advanced chromatherapy network allows you to effortlessly customize the atmosphere via remote control, bathing the smooth wood textures in calming waves of healing light tailored for meditation or intense post-workout relaxation.

Beneath its polished Scandinavian styling, the Fortis is packed with high-performance, all-weather engineering. Driving the thermal environment is a powerful 9kW Harvia Virta electric heater, fully integrated with smart Wi-Fi capabilities for seamless smartphone app automation from anywhere. Underneath the premium finishes, advanced multi-layer wall insulation packed with eco-friendly wood fibers works alongside a weather-fortified roof shell to lock in radiant heat with extreme efficiency, keeping energy consumption low even in freezing climates. Delivered fully pre-assembled from the factory via flatbed for a fast, turnkey installation, this connected oasis delivers an uncompromising backyard retreat built for luxury year-round rejuvenation.
