Product Highlights
Carbonized Walnut Construction
The carbonization process enhances walnut wood's natural resistance to moisture, warping, and weathering. The resulting gray-black finish is both visually distinctive and practical for outdoor placement in variable climates.
360-Degree Carbon Crystal Infrared Heating
Six carbon crystal heating plates are positioned around the interior to distribute warmth from multiple directions simultaneously. This layout reduces cold spots and provides more consistent heat coverage compared to single-panel systems.
Hillside Pitched Roof
The angled roof design channels rain and snow away from the structure efficiently, adding a layer of weather protection that helps extend the sauna's outdoor lifespan.
Low EMF Heating System
The 1,750W heating system is engineered to minimize electromagnetic field output, a specification commonly prioritized by buyers focused on wellness-oriented product design.
7-Color Chromotherapy LED Lighting
Adjustable color LED lighting lets you customize the ambiance of each session. A separate eye-care reading light is also included for use during longer sessions.
Integrated Bluetooth Audio
Built-in Bluetooth speakers connect wirelessly to your phone or tablet, letting you play music, podcasts, or guided audio without bringing external devices into the sauna environment.
