Premium Materials, Inside and Out

 

 

Every surface of the GL4 reflects SaunaLife’s commitment to quality.

 

 

• 1.57” thick Thermo-Spruce exterior walls for durability and longevity

• Thermally treated wood resists moisture, decay, and fungi far better than conventional timber

• Two-tier bench layout allows bathers to choose their ideal heat level

 

 

The materials are chosen not only for beauty, but for years of reliable outdoor use.

Light-Filled Sauna Experience

 

 

The expansive glass front transforms the interior atmosphere.

 

 

• Brings abundant natural daylight into the sauna

• Enhances the sense of space and openness

• Frames calming outdoor views while bathing

• Uses tempered bronze glass for strength, warmth, and privacy

 

 

The result is a sauna that feels bright, calming, and deeply connected to its surroundings.

Elegant, Layered Illumination

 

 

Lighting is thoughtfully integrated to enhance both safety and ambiance.

 

 

Exterior lighting

• Full-width dotless LED lighting beneath the eaves

• Softly illuminates the porch and entry for evening use

Interior lighting

• Indirect LED lighting highlights the natural wood grain

• Produces a gentle, diffuse glow throughout the sauna

• Wi-Fi app control or handheld remote for easy adjustment

 

 

Lighting becomes part of the ritual—subtle, warm, and immersive.
