ThermaSol Fully Assembled Outdoor Sauna, Modular, 2 to 5 Person
The ThermaSol Nordic Misty Sauna Cabin is the centrepiece of the Nordic Misty Collection a fully assembled, turnkey outdoor sauna that arrives with a complete roof, a Harvia heater with sauna stones, all electrical pre-wiring, and every accessory required for your first session, ready to use the moment it is placed. There is no kit to assemble, no components to order separately, and no contractor required. This is the outdoor sauna that is genuinely ready to go in two sizes, with a choice of electric or wood-burning heat, and designed to grow into a full outdoor wellness complex whenever you are ready.
A panoramic tinted double-glazed glass wall unlike any other outdoor sauna
The Nordic Misty's defining visual feature is the panoramic tinted glass wall that spans the entire front face of the cabin. Unlike a standard glass door or a window panel, this is a full-width, double-glazed glass system insulated with a dead-air gap for thermal efficiency and tinted to maintain complete privacy during daytime sessions. From inside, the view opens across your garden or landscape, making every session a genuinely outdoor experience in the most immersive sense. From outside, the dark tint and dark spruce exterior read as a single dark, sleek architectural form. The result is a sauna that looks dramatic from the garden and transformative from within.
The full-length glass door secure, smooth, and private
Set within the panoramic glass wall, the full-length tinted glass door opens with a smooth roller latch and a warm wooden handle. An external lock set with a padlock and two keys keeps the cabin secure between sessions. The door fits flush with the glass wall with no visible threshold or frame break, maintaining the clean, continuous visual line of the front face. The heat-treated aspen interior immediately greets you as you step in smooth, stable, and completely free of the resin and knot issues that affect lesser wood species at sauna temperatures.
Liftable thermo-aspen benches designed to be lived in
Both the upper and lower benches are made from lightweight, heat-treated aspen and are specifically designed to be liftable for easy cleaning a detail that separates the Nordic Misty from most permanently-mounted bench systems. Soft recessed LED lighting is positioned under the lower bench and above the backrest, creating a warm, low-level glow that accentuates the wood grain and sets the mood without ever drawing attention to itself. The LED system is pre-wired and operational immediately on delivery. Heat your sauna before you arrive using the included Wi-Fi-connected Harvia heater compatible with the Harvia app for remote temperature control, scheduling, and session management.
Arrives with everything including the accessories
Each Nordic Misty Sauna Cabin ships with a Deluxe Onyx Black accessories set: a stainless steel bucket, a matching stainless ladle, and an easy-to-read combined thermometer and hygrometer. The selected Harvia heater includes a full load of sauna stones. All electrical pre-wiring is complete a licensed electrician is required only to make the final hardwired connection at the junction box. The cabin is placed on a firm, level surface (concrete, decking, pavers, or compacted gravel with slight runoff for drainage) and connected to your site's electrical supply. That is the full scope of the installation. ThermaSol notifies customers two weeks prior to the scheduled delivery to allow time for preparation and equipment arrangement.

About ThermaSol
The Nordic Misty Collection a wellness system, not just a sauna
ThermaSol designed the Nordic Misty collection around a single idea: your outdoor wellness space should be able to grow over time without requiring you to start over. The Nordic Misty Sauna Cabin is the foundation the piece you place first and the piece every other module connects to. The Nordic Misty Changing Room attaches directly to prepare and transition. The Lounge provides a full enclosed relaxation and entertainment space. The Terrace extends the outdoor living area further still.
Every module ships fully assembled and connects to the sauna or to each other at any point after the initial installation. ThermaSol notifies customers two weeks prior to the scheduled delivery date to allow time for preparation. A forklift or crane is preferred for safe unloading customers should confirm the path from the delivery point to the placement site is clear, level, and accessible for equipment in advance of the delivery appointment.
