Description

The SaunaLife Garden Luxury-Series Model GL4B Outdoor Sauna combines contemporary Scandinavian design with premium materials and a striking black exterior finish. Its clean architectural lines, integrated eaves and porch, and expansive bronze tempered-glass front create an inviting backyard retreat that feels both modern and timeless.

Lustrous Black Finish

The GL4B includes two 2.7-liter containers of PROSAUNAS SaunaShield Black Sauna Paint, specially formulated to protect the exterior wood while creating a refined, contemporary appearance. Designed to accommodate natural expansion and contraction as temperatures change, the black finish complements the sauna's architectural lines and contrasting exterior details.

Premium-Quality Materials

Constructed with 1.57-inch-thick Nordic Thermo-Spruce, the GL4B is designed for outdoor durability and improved resistance to moisture, decay, and fungal growth. The full-height bronze tempered-glass front creates an open visual feel, while the two-tier thermo-hardwood benches and backrests provide comfortable seating with a smooth, carefully finished surface.

Elegantly Illuminated

Integrated, full-width exterior LED lighting illuminates the porch and entry beneath the eaves. Inside, indirect LED lighting creates a soft, inviting atmosphere that highlights the wood interior. The white LED lighting system can be controlled through a Wi-Fi app or the included handheld remote.

Designed for Outdoor Durability

Roofing felt, black metal flashing, durable roof boards, ventilation, and drainage features help protect the structure from the elements. Interlocking-beam construction accommodates the natural movement of wood, while the integrated porch creates a welcoming transition into your outdoor sauna.

Designed for a straightforward DIY installation, the SaunaLife GL4B includes the construction materials, fasteners, and assembly instructions needed to build your outdoor sauna. Its thoughtfully engineered design makes it easier to create a refined backyard sauna retreat.
