SaunaLife GL4
The SaunaLife Model GL4 is a modular outdoor sauna designed to accommodate up to 4 people comfortably. Built from premium thermo-spruce, it delivers long-term durability, thermal efficiency, and a refined Scandinavian aesthetic. The kit is engineered for straightforward installation, allowing two people to complete assembly in approximately two days.
Sauna Notes
The GL4 features a contemporary linear design with integrated eaves and a defined porch area, creating a clean architectural profile suitable for modern outdoor spaces. The contrasting black trim and fascia provide visual depth while maintaining a minimal, structured appearance.
Thermo-spruce is used throughout the exterior, offering enhanced resistance to moisture, decay, and environmental stress. The material is thermally treated to improve stability and longevity while preserving the natural grain texture.
The interior is fitted with two-tier thermo-hardwood benches designed for ergonomic support and long-term comfort. The smooth, knot-free finish enhances usability while maintaining structural durability under repeated heat cycles.
A full front wall of tempered bronze glass expands visibility and natural light, reducing enclosure while maintaining heat retention. The door and window system integrates cleanly into the structure with black-framed detailing.
Lighting is integrated both externally and internally. A recessed LED strip under the eaves provides functional illumination at the entrance, while interior indirect LED lighting creates a soft, evenly distributed glow controlled via Wi-Fi or remote.
The structure is designed for all-weather performance with thick wall panels, integrated drainage, ventilation, and roofing systems. Interlocking beam construction allows for natural expansion and contraction, maintaining structural integrity over time.
