The SaunaLife GL4B outdoor sauna kit creates a private backyard retreat for up to four people, combining traditional sauna warmth with contemporary Scandinavian design. Part of the Garden Luxury Series, this four-person outdoor sauna features Thermo-Spruce construction, bronze-tinted glass, sculpted two-level seating and integrated LED lighting for an inviting home sauna experience.
A considered garden retreat
A recessed glazed entrance, integrated porch and clean horizontal eaves give the GL4B a composed, architectural presence. Natural wood and bronze-tinted glass create a warm, restful setting for your garden sauna.
Comfort in every detail
Sculpted two-level seating invites you to settle in, offering a choice of position whether you are enjoying a quiet session or sharing the warmth.
Gentle light, inside and out
Exterior LED lighting illuminates the entrance, while indirect interior lighting highlights the warmth of the wood. Wireless handheld control lets you adjust the lighting for evening sessions.
A black finish, completed on site
Two 2.7 L containers of PROSAUNAS SaunaShield Black Sauna Paint are included for application during assembly, allowing you to finish the sauna exterior in black on site.
A compatible sauna heater is required and sold separately.

Delivery Details
Your sauna kit is delivered by appointment via freight carrier and arrives on a wooden pallet. Delivery includes curbside service, with the carrier lowering the shipment to ground level.

Installation & Warranty
Assembly and site preparation. This is an on site assembly kit. Read the model-specific manual before work begins and prepare a stable, level foundation with drainage and adequate load capacity. Plan room to handle the glass and assemble the roof safely.
Electrical installation. Have a qualified electrician install the lighting and selected heater system to their manuals and local requirements. The lighting requires a 120 V AC supply; this does not establish the heater’s electrical requirements. Protect the lighting driver, power supply and controls from rain and moisture.
Heater selection. Select the heater for this room’s dimensions, glazing, climate and installation clearances. The supplied room or guard does not establish compatibility with every heater. Follow the chosen heater’s ventilation, wiring and safety requirements.
Residential warranty. The current SaunaLife limited warranty lists five years for sauna rooms and kits from delivery, for the original retail purchaser buying through an authorized reseller. Coverage is subject to the manufacturer’s terms and exclusions; normal wood aging, weathering, installation labor and commercial use are not covered.
