The Heritage Sauna® Lux Serena is a spacious 4–6 person Nordic-style sauna designed for residential indoor or outdoor installation. Crafted from untreated Nordic Spruce with a solid interlocking log construction, its 1.1" walls provide insulation and year-round durability. The sleek flat-roof design features a full tempered-glass front that brings natural light into the interior and creates an open connection to the surrounding space. A solid spruce base provides a defined foundation for indoor installation.
Inside, three extra-wide benches, each approximately 21.7" wide, provide generous space for upright seating or reclining. The double roof includes an insulated inner layer and an outer layer of spruce boards, while small gaps between the glass panels allow airflow. A wall lamp and shade provide soft lighting. The exterior is available in natural spruce or an optional black finish, with a natural spruce interior, allowing the Serena to complement a range of indoor and outdoor settings.
