Modern Glass Design Meets Traditional Sauna Heat

The ThermaSol Lumaria is a premium indoor sauna cabin designed to bring a spacious, contemporary aesthetic to the home wellness environment. The Medium configuration accommodates 2–3 people and combines a corner-friendly footprint with a panoramic transparent glass front for an open, light-filled appearance.

The cabin features Brushed Tyrol wood interior walls, thermally modified Aspen benches and backrests, and integrated RGB LED color lighting beneath the benches and behind the backrests. A 9kW Harvia Virta sauna heater with Wi-Fi provides the traditional sauna heat, while the mirrored left- or right-assembly options allow the layout to be configured around the room.

The Lumaria arrives with pre-assembled panels and is installed as a freestanding indoor sauna. Its assembled dimensions are approximately 86.6" L × 66.9" W × 83" H, with a listed assembled weight of approximately 1,323 lbs.

Why You'll Love It

2–3 Person Capacity

The Medium Lumaria is designed for 2–3 people, making it suitable for shared sauna sessions while retaining a practical residential footprint.

Panoramic Transparent Glass

The panoramic glass front creates a bright, open appearance and provides visibility into the cabin while maintaining the enclosed sauna environment.

Brushed Tyrol Wood Interior

The interior walls feature Brushed Tyrol wood, adding natural texture and a refined finish to the contemporary glass-and-wood design.

Thermally Modified Aspen Benches

The benches and backrests use thermally modified Aspen, providing a warm, natural seating surface designed specifically for the sauna environment.

9kW Harvia Virta Heater

The Lumaria includes a 9kW Harvia Virta electric sauna heater with Wi-Fi, providing the heat source for traditional sauna bathing.

Wi-Fi-Enabled Control

The included Virta configuration features Wi-Fi-enabled controls, providing convenient access to sauna-management functions.

RGB LED Color Lighting

Integrated RGB LED lighting is positioned beneath the benches and behind the backrests. The lighting system is controlled remotely, allowing customers to personalize the cabin's ambiance.

Multi-Layer Natural Wood-Fiber Insulation

ThermaSol incorporates multi-layer wall construction with natural wood-fiber insulation as part of the Lumaria's cabin design.

Corner-Friendly Layout

The Lumaria is designed to make efficient use of a corner while maintaining a large glass presence at the front of the cabin.

Left or Right Assembly

Customers can select left or right mirrored assembly, allowing the glass corner and heater position to work with the room layout.

Dual-Height Bench Configuration

The cabin's seating arrangement incorporates different bench heights, creating flexibility in seating position within the sauna.

Freestanding Indoor Construction

The Lumaria is designed as a freestanding indoor sauna that can be disassembled and relocated when necessary.

Designed for an Elevated Home Wellness Space

The Lumaria is designed for customers who want more than a basic sauna enclosure. Its combination of panoramic glass, natural wood, modern lighting, and smart heater controls gives it the look of a built-in architectural wellness feature while remaining a freestanding cabin.

The Medium configuration measures approximately 86.6" × 66.9" × 83", making it suitable for dedicated wellness rooms, home gyms, primary suites, and other appropriately prepared indoor spaces.

Because the assembled unit weighs approximately 1,323 lbs and the shipping weight is approximately 1,543 lbs, delivery access and installation planning are especially important.

What's Included

The ThermaSol Lumaria Medium package includes the primary sauna cabin components and integrated systems:

• Lumaria Medium sauna cabin

• Thermally modified Aspen benches
• Thermally modified Aspen backrests
• Transparent panoramic glass
• 9kW Harvia Virta heater with Wi-Fi

Sauna Stones

ThermaSol's current Lumaria page identifies the Virta heater but does not clearly state that sauna stones are included. The standalone Harvia Virta heater documentation treats stones separately, so I recommend confirming stones for the exact WEF package before listing them as included.

Optional Add-Ons

Sauna Stones

Sauna stones are required for traditional stone-heater operation. Confirm the exact WEF package before presenting them as included.

Assembly Orientation

The Lumaria is available in left or right mirrored assembly configurations. This is a product configuration rather than an aftermarket accessory.

Shipping & Installation

The Lumaria is delivered with pre-assembled panels and detailed installation instructions. ThermaSol states that indoor saunas are delivered via flatbed trailer, with customers notified approximately two weeks before scheduled delivery to allow adequate site preparation.

The manufacturer states that assembly typically requires two people, basic tools, and a few hours.

The cabin measures approximately 86.6" L × 66.9" W × 83" H and has an assembled weight of approximately 1,323 lbs, so the delivery route, doorways, hallways, stairs, and final placement area should be evaluated in advance.

ThermaSol specifies a level, water-resistant floor for its indoor saunas. Suitable surfaces include concrete, ceramic tile, vinyl, and laminate.

The included 9kW Harvia Virta heater requires appropriate electrical installation, and ThermaSol states that a licensed electrician must install the heater.
