SaunaLife GL4 Garden Luxury 4-Person Outdoor Sauna Kit

Inside the cabin

What four people actually get

The front is a full-height bronze glass wall and door, so the room looks out rather than in, and the two-tier benching follows the contour of your back instead of sitting square.

Inside the cabin

Interior	55.5 × 59.1 × 76 in (141 × 150 × 193 cm)
Exterior	58.9 × 79.5 × 85.1 in (150 × 202 × 216 cm)
Footprint	32.5 sq ft
Interior volume	144 cu ft
Covered porch	58.9 × 14.6 in (150 × 37 cm), under the eaves
Front wall	Full-height tempered bronze glass, 8 mm
Door	27.6 × 74.8 in (70 × 190 cm), bronze glass, reversible

The exterior footprint includes the porch, so the heated room is the 55.5 by 59.1 inch space behind the glass. Measure the ground for the full 58.9 by 79.5 inches, and plan the approach to the porch side, because that is where you step in and where the eaves lighting falls.

The one choice you make

Natural or black

What the choice changes

Natural	Thermo-Spruce left to weather, with the black trim, fascia and flashing as standard
Black	The same cabin with the cladding painted black, which sets the bronze glass and the eaves line harder against it
What does not change	Everything else. Same dimensions, same benching, same glass, same heater range, same warranty

Choose the finish in the Finish control above Add to Cart. Black is a factory finish on the cladding, so it is settled when you order rather than something to repaint later.

The decision that blocks the purchase

Choosing the heater for your GL4

Two decisions, in this order: how many kilowatts, then which heater. The kilowatts follow the room, and at 144 cubic feet behind a full glass wall the GL4 takes 6 to 7 kW.

These are the five we sell for it, and they are the five behind the Add a heater and accessories button above Add to Cart. Each is a package: heater, control and stones together, so nothing is missing when the pallet arrives.

Browse Harvia sauna heaters or electric sauna heaters if you want to see the full range first.

What your electrician needs to know

The heater is hard-wired onto its own 240-volt circuit, not plugged in. Your electrician sizes the breaker and the cable from the installation instructions for that heater and from your local code, and for a garden cabin that run is usually the longest part of the job. The kit carries its own ventilation system, so the air path is built in rather than something the electrician has to allow for.

No heater guard comes with a Garden Luxury cabin, so read the safety distances in your heater's installation instructions and set the benches and the heater position to them. Every heater publishes its own, and they differ between a wall unit and a floor-standing one.

Before you order

Five things to check before the GL4 ships

None of these is hard. All of them are easier to answer now than on the day the pallet is standing in your driveway.

• Is the base level, and does it drain?32.5 square feet carrying 1,650 pounds before bathers and water. A slab, piers or a timber frame all work if they are level and shed water. The ground frame is in the kit; what sits under it is yours.
• Have you allowed for the porch?The 79.5 inch depth includes the covered porch. Leave room to stand on it and open the door, rather than measuring to the glass.
• Has your electrician seen your panel?The heater is hard-wired onto its own circuit. Your electrician will tell you in one visit whether your panel has room and what the run to the garden will cost.
• Can the pallet reach you?It arrives by LTL freight at 84 by 46 by 42 inches. Check the approach for the truck and the route from the kerb to the spot.
• Does your town want a permit?Ask your building department whether the structure, the electrical work or both need one, and what setbacks apply to your lot.

Assembly

Building the SaunaLife GL4

Two days, two people. SaunaLife engineers the GL4 for a DIY build and publishes that figure.

The walls are interlocking beams rather than panels, so they stack and lock as you go and the cabin finds its own square. The order is the ground frame down and levelled, the walls up course by course, the roof boards and the self-adhesive felt, then the flashing and fascia, the glass wall and door, the benches and backrests, and the lighting last. Every fastener the build needs is in the kit.

If you would rather not build it yourself, professional setup and assembly is quoted for your address. Ask for a quote here and the form opens on this page.

After the sale

Who stands behind the GL4, and for how long

Two companies stand behind your sauna: SaunaLife for the cabin, and whoever made the heater for the heater. Both are written warranties, and between them your whole purchase is covered.

Keep SaunaLife's warranty with your heater's, your delivery receipt and your electrician's invoice, and a claim takes one phone call instead of three.

Construction

What the GL4 is made of

Thermally treated spruce, at 1.57 inches. Heat and steam drive the moisture and resin out of the timber, which is what leaves it stable outdoors and more resistant to moisture, decay and fungi than untreated wood. The walls and the roof are both at 1.57 inches; the porch and floor boards are 1.1.

Interlocking beams, not panels. The walls stack and lock, which lets the timber expand and contract across a year of weather instead of fighting the fasteners. It is also what makes a two-day build realistic without a carpenter.

Water managed, not just shed. Roofing felt over the roof boards, black metal flashing at the joints, fascia boards at the eaves and a drainage system in the kit. The eaves overhang is doing a job as well as setting the look: it keeps the glass and the porch out of the rain.

Lit from the eaves and from behind the backrest. A full-width recessed LED strip under the eaves lights the porch and the entry, and the interior lighting is indirect rather than overhead, so nothing glares at a bather lying back. Both run from the Wi-Fi app or the handheld remote.

An outdoor sauna heated by stones. The Garden Luxury Series sits in the full SaunaLife range.

The real comparison

The GL4 against the other SaunaLife kits for four

The GL4 is cross-shopped against two cabins: the CL5G cube, which gives you a bigger room on a bigger footprint for a plainer building, and the GL6, which is this same Garden Luxury design one size up.

	SaunaLifeGL4You are here	SaunaLifeCL5G	SaunaLifeGL6
Bathers, up to	4	4	6
Footprint	32.5 sq ft	35.3 sq ft	56.5 sq ft
Interior volume	144 cu ft	184 cu ft	222 cu ft
Covered porch	Yes, 58.9 × 14.6 in	None	Yes

Heater band	6 to 7 kW	6 to 7.5 kW	9 to 10.6 kW
Product weight	1,650 lbs	1,680 lbs	2,200 lbs

Choose the GL4 when the sauna will be seen from the house and the covered porch and the eaves lighting are part of why you want it, and when 32.5 square feet is what the garden can give. Choose the CL5G when you want the largest room for four and the building itself matters less. Choose the GL6 when you want this design but six people in it.
