The Heritage Sauna® Lux IR Duo is a 2-person indoor infrared sauna built from insulated Canadian hemlock with recessed top and bottom panels for a clean, built-in appearance. Its 51.2" W × 43.3" D × 74.8" H footprint provides side-by-side seating space for two adults, while the 1750 W low-EMF carbon heating system delivers warmth throughout the cabin. The 8 mm bronze-tinted tempered privacy-glass door features a solid wood handle and right-hand opening, complementing the modern horizontal-slat exterior.
Inside, carbon heating panels surround the back, sides, and calves, while ergonomic backrests and heater guards support comfortable seating for two. WiFi controls provide smartphone operation of temperature, lighting, and session time, with a ceiling chromotherapy lamp and LED accent strips adding layered interior lighting. An integrated ionizer and Bluetooth-connected speakers add air and audio features. The plug-and-play design uses a standard 120V/15A NEMA 5-15 connection with a heavy-duty 12-gauge cord and dedicated circuit, while buckle connections allow tool-free assembly. The sauna is ETL certified and includes a 2-year limited warranty.
