SaunaLife GL6 6 Person Garden Luxury Outdoor Sauna Kit

Architectural Outdoor Design

The GL6 has a true backyard retreat presence, with a modern rectangular form, integrated porch, wrap-around horizontal eaves, black trim, and full bronze glass front windows.

Spacious 6-Person Layout

Designed for up to 6 sauna bathers, the GL6 gives you more room for family, guests, stretching out, and shared sauna rituals.

Premium Thermo-Spruce Construction

The sauna uses 1.57” thick Nordic Thermo-Spruce walls, offering a durable outdoor structure with a warm natural look and improved resistance to moisture, decay, and fungi.

Full Bronze Glass Front + Side Door

The tempered bronze glass windows and side door create a bright, open sauna interior while giving the GL6 its signature modern luxury appearance.

Integrated Porch + Wrap-Around Eaves

The porch and eaves make the GL6 feel more finished than a standard sauna kit, creating a more inviting entry and a stronger architectural presence.

Interior and Exterior LED Lighting

Recessed exterior LED lighting illuminates the porch and entry, while indirect interior LED lighting creates a soft glow inside the sauna. The lighting system includes WiFi app-based operation and a wireless handheld remote.

Comfortable Two-Tier Benching

The GL6 includes extra-thick, silky-smooth, ergonomically designed two-tier seating with thermo-hardwood benches and backrests.

Pro-Quality DIY Assembly

The GL6 is engineered for 2-person, 2-day DIY assembly by people with moderate DIY experience, with construction materials, fasteners, and installation instructions included.

What Makes the SaunaLife GL6 Different?

A True Outdoor Sauna Retreat — Not Just a Sauna Cabin

The SaunaLife GL6 stands out because it feels like a complete outdoor wellness structure, not just a simple sauna room.

The integrated porch, wrap-around eaves, black architectural trim, bronze glass front, and soft LED lighting give the sauna a polished, luxury presence. The thick Thermo-Spruce walls, roofing system, flashing, drainage, ventilation, and insulation components help support outdoor performance and long-term durability.

For homeowners who want a backyard sauna that looks intentional, elevated, and beautifully finished, the GL6 is one of SaunaLife’s most compelling outdoor kit designs.

Is the SaunaLife GL6 Right for Your Space?

Best for a Spacious Backyard Wellness Retreat

The GL6 is ideal for customers who want a larger outdoor sauna kit with a modern Scandinavian look, generous benching, glass-forward design, and refined backyard presence.

The exterior measures approximately 90.2”W x 90.2”D x 92.5”H, with an integrated porch depth of 14.6”. The interior measures approximately 69.7”W x 69.7”D x 79.1”H, creating a comfortable traditional sauna environment for up to 6 bathers.

Before ordering, confirm:

• Final sauna location
  
• Level foundation or pad size
  
• Access from curbside delivery to build site
  
• Local code or HOA requirements
  
• Electrical path for heater and lighting
  
• Heater size and control placement
  
• Assembly help and timeline
  
• Clearance around the sauna for installation and service
  

For the foundation, we generally recommend a stable, level base such as compacted gravel, concrete, pavers, or a properly reinforced deck. A pad that extends several inches beyond the sauna footprint on all sides is helpful for stability, drainage, and installation access.
