The SaunaLife Model GL6 is the most spacious and architecturally refined sauna in the SaunaLife outdoor lineup — a professional-quality, authentic Scandinavian sauna cabin engineered for up to 6 persons and designed to be the centerpiece of any backyard. Handcrafted in Northern Europe by sauna enthusiasts, the GL6 brings commercial-caliber build quality to a DIY-friendly kit that two people with moderate construction experience can complete in two days.

Where most outdoor sauna kits prioritize function over aesthetics, the GL6 delivers both without compromise. Its contemporary linear architecture, contrasting black exterior trim, integrated wrap-around porch, and floor-to-ceiling tempered bronze glass front create an appearance that looks custom-built and permanent — not assembled from a kit.

DESIGN AND ARCHITECTURE

The GL6's exterior design is built around a modern horizontal aesthetic anchored by several distinctive architectural elements. The wrap-around eaves and integrated porch create a covered entry that gives the structure a set-back, intentional appearance rarely seen at this price point. Recessed LED lights beneath the eaves illuminate the porch and pathway after dark, guiding bathers safely to the entrance.

The full-height tempered bronze glass front window spanning 32.5 inches wide by 72 inches tall floods the interior with natural light and provides unobstructed outward views — a feature that dramatically enhances the sense of space inside the cabin. The tempered bronze glass side door with full-height black door pull completes the contemporary glass-and-timber aesthetic.

MATERIALS AND CONSTRUCTION

The GL6 is built from 1.57-inch thick thermally treated Nordic spruce throughout — one of the thickest wall specifications available in a DIY outdoor sauna kit. Thermally modified spruce outperforms conventional cedar and untreated lumber in outdoor conditions, offering significantly greater resistance to moisture, decay, and fungi without the use of any chemical treatments. The thermal modification process is entirely eco-friendly, relying only on heat and steam to restructure the wood at a cellular level.

Interlocking-beam construction allows the walls to expand and contract naturally with temperature and humidity changes — an important design consideration for outdoor saunas that experience year-round weather cycles. This construction method creates an exacting, gap-free fit that improves thermal retention and long-term structural integrity.

The roof is constructed from thermo-spruce exterior and interior boards, with self-adhesive roofing felt, metal flashing, and black fascia boards providing professional-grade weather management and a reliably dry interior in all conditions.

SEATING AND INTERIOR COMFORT

The GL6 interior accommodates up to 6 bathers across two tiers of ergonomically contoured benches crafted from silky-smooth knot-free thermo-hardwood. The upper bench measures 69.7 inches wide by 23.6 inches deep — generous enough for bathers to lie down fully — while the lower bench at 69.7 inches wide by 12.5 inches deep provides a comfortable second tier for additional bathers or footrests. The 79.1-inch interior ceiling height allows most users to stand fully upright with ease.

Thermo-spruce floorboards and porch boards complete the interior and exterior floor surfaces, both at 1.1 inches thick for a solid, premium underfoot feel.

LED LIGHTING INSIDE AND OUT

The GL6 includes a full dual-zone LED lighting system — exterior recessed lights beneath the eaves and indirect interior LED lighting inside the cabin — both controlled via Wi-Fi app or wireless handheld remote. The interior indirect lighting produces a diffuse, even glow that highlights the natural grain and warmth of the wood interior without harsh direct light. The system allows bathers to set the ideal scene before entering and adjust lighting during the session without getting up.

ENGINEERED FOR DIY INSTALLATION

SaunaLife has refined their DIY sauna kit format over many years and the GL6 reflects that experience. Straight-forward installation instructions, meticulous component labeling, and intuitive interlocking-beam assembly allow two people with moderate DIY experience to achieve professional results in two days. All construction materials and fasteners are included — nothing additional needs to be sourced before starting the build.
