The exact matching product is SAK70182.

The sauna features a gambrel roof designed to improve rain and snow drainage, while its carbonized composite construction is positioned as a durable alternative to conventional wood.

Designed for Relaxation & Everyday Wellness

The Eterna brings together infrared heating, lighting, and audio in one dedicated cabin. Its combination of six heating plates and 360-degree heat distribution is designed to provide an enveloping infrared environment rather than relying on a single heating source.

The cabin's entertainment features add another layer of convenience, allowing you to create a personalized environment for quiet relaxation, music, reading, or conversation.

Carbonized Composite Construction

The current listing identifies the material as a carbonized wood-plastic composite. The product description positions this material as resistant to warping and cracking and suitable for demanding temperature and humidity conditions.

The source also claims resistance to mold, insects, and water damage. These are manufacturer/seller claims rather than independently verified performance ratings, so they should not be interpreted as a guarantee of service life.

Six Carbon Crystal Heating Plates

The Eterna uses six carbon crystal heating plates arranged to provide 360-degree surround infrared heating. The published electrical specification is 1,750W at 120V and 60Hz.

The source does not publish a standardized irradiance measurement or individual infrared wavelength specifications, so those figures have not been added.

Seven-Color Ambient Lighting

Integrated seven-color lighting lets you change the visual atmosphere of the cabin. The source describes the feature as a physical-therapy/chromotherapy-style light, but this listing presents it conservatively as multicolor ambient lighting rather than making unsupported therapeutic claims.

Bluetooth Audio & Reading Light

Built-in Bluetooth stereo speakers allow compatible devices to provide music and other audio during sessions. An eye-care reading light is also included for additional interior illumination.

Gambrel Roof for Outdoor Placement

The Eterna uses a gambrel-style roof, which provides a sloped profile for rain and snow drainage. The product listing specifically positions the design for resistance to a range of weather conditions.

Product Specifications

The matching SAK70182 listing confirms the model, heating system, power, lighting, Bluetooth audio, roof design, and published dimensions.

What's Included

The matching product information identifies the following core features/components:

• Thermora Eterna sauna room
• Six carbon crystal heating plates
• LCD/touch control system
• Seven-color lighting
• Bluetooth stereo speakers
• Eye-care reading light
• Gambrel roof structure

The accessible product page does not provide a sufficiently detailed packing list for every hardware component or accessory, so additional items have not been assumed.

Installation

The current product is presented as a sauna room with a modular-style construction. Assembly and placement should follow the supplied instructions and site requirements.

Because the published product information contains conflicting occupancy language and dimensions that appear unusually compact for a four-person sauna, customers should confirm the final physical configuration before installation.

Outdoor Installation Considerations

The product listing presents the Eterna as suitable for outdoor environments and specifically highlights its gambrel roof and weather-oriented construction.

Install the sauna on an appropriate level surface with sufficient clearance for access, ventilation, maintenance, and electrical connections. The electrical installation should comply with local requirements for a 120V sauna appliance.

Care & Maintenance

Keep the sauna interior clean and dry between sessions. Regularly inspect the exterior composite panels, roof, door, controls, heating plates, lighting, and electrical connections.

Follow the supplied care instructions for the composite material and avoid harsh cleaners that could damage the finish or components.

Warranty

The exact matching SAK70182 listings reviewed do not clearly publish a product-specific warranty term. The source does advertise a 30-day return policy, but that should not be represented as a manufacturer's warranty.

The draft's claim of a 2-year full warranty and 5-year core-technology warranty was not sufficiently established on the current matching product page, so it has not been presented as a confirmed warranty.

Safety & Usage Information

Use the sauna according to the supplied manufacturer's operating instructions.

The listed electrical requirement is 120V/60Hz with 1,750W output. Ensure the electrical connection is appropriate for the actual delivered configuration and compliant with local electrical requirements.

The original draft included claims about detoxification, circulation, immune support, skin health, and other therapeutic effects. These have been removed or moderated because the available product specifications do not establish guaranteed medical outcomes.
