SaunaLife G2 | Traditional Outdoor Sauna · 4-Person

The SaunaLife G2 is a 4-person traditional outdoor sauna kit built from 1.65" Nordic Spruce planks with interlocking V-joints, under a single-pitch roof with a self-adhesive roll roofing membrane. The walls enclose a footprint of 71.8" W × 64.2" D and an interior of 67.3" W × 60" D × 75.5" H, with a two-tier knotless Aspen bench and backrest inside and a 5/16" tempered glass door at the front. The kit includes the structure, floor, benches, exterior trim and the Wi-Fi LED lighting system, and ships flat-packed by LTL freight at a listed 1,200 lbs. The sauna heater is chosen separately.

Designed by SaunaLife and crafted in Northern Europe, the G2 is the smallest cabin in the Garden-Series and is the one model in the range that SaunaLife specifies for either an electric heater or a wood-fired stove. The roof slopes from 86.4" at the door down to 79.9" at the back, which keeps the overall height low enough to sit unobtrusively against a fence line while still giving 75.5" of headroom inside.

How the SaunaLife G2 is built

The G2 uses solid timber rather than a panel system: the walls are stacked planks that interlock along a machined V-joint, carried on four square corner posts and a treated foundation frame.

• 1.65" interlocking spruce walls: Nordic Spruce planks 1.65" thick and 5.7" wide, machined with a V-joint so each course locks into the one below. Corner posts are 1.73" square.
• Knotless Aspen interior: the two-tier bench, the side bench and the backrests are knotless Aspen, chosen because a knot-free seating surface stays more comfortable against bare skin at sauna temperatures.
• Tempered glass door: 5/16" clear tempered glass in a 27.2" W × 66.6" H opening, with an aluminium exterior handle and a wood interior handle.
• Single-pitch roof: spruce roof boards covered with a self-adhesive roll roofing membrane, overhanging the walls by about 4.7".
• Wi-Fi LED lighting: a dotless white LED bar run from a 90 W low-voltage supply, controlled from a phone app or the included wireless handheld remote.
• Ventilation: one 3.9" exhaust vent, with the hole drilled during assembly and the cover supplied in the kit.

What comes with the SaunaLife G2?

The SaunaLife G2 ships as a complete sauna room kit with everything except the heater: the pre-machined spruce structure and floor, the foundation beams, the tempered glass door, the roofing membrane, exterior trim, the knotless Aspen benches and backrests, the full Wi-Fi LED lighting system, all fasteners and the installation manual. The heater, its controls, the sauna stones and the electrical work are not included.

Does the SaunaLife G2 include a heater?

No. The SaunaLife G2 is a sauna room kit, so the heater, its control unit and the sauna stones are chosen separately and ordered with the sauna. SaunaLife specifies the G2 for a 6 kW electric sauna heater or for a wood-fired sauna stove.

Four heater packages are offered for this sauna, selectable above, and each includes the heater, its control and its stones:

• HUUM DROP 6 kW electric, with UKU local or Wi-Fi control — marked Recommended, and the package that matches SaunaLife's own 6 kW specification
• Harvia KIP 8 kW electric, with Xenio Wi-Fi control
• Harvia KIP 8 kW electric, with built-in controls on the heater
• Harvia M3 16.5 kW wood-burning stove kit, with chimney, wall sheath, floor protection and stones

The 8 kW and 16.5 kW packages are rated by their manufacturers for rooms larger than the G2's, so if you are drawn to one of those rather than the 6 kW, contact us before ordering and we will confirm the sizing with the manufacturer. The Compare Heater Packages link on this page sets out what each one contains.

Can you assemble the SaunaLife G2 yourself?

The structure, yes; the electrical work, no. The SaunaLife G2 arrives flat-packed with pre-machined V-joint wall planks, a full fastener kit and an illustrated step-by-step manual, and SaunaLife describes the build as a two-person, two-day job. It is not a no-cut kit: the manual instructs you to cut the last floor board to fit and to drill the 3.9" ventilation hole through the wall during assembly, so a saw and a drill are needed on site. Every fastening point is pre-drilled with a 4 mm bit before the screw goes in.

The electrical side is not a DIY step. SaunaLife's Garden-Series owner instructions say to hire qualified professionals for electrical work, including heater and lighting installation — so the heater, its control unit and the LED lighting are wired by a licensed electrician, not by you. Plan the structure as a weekend project for two people and book the electrician separately.

Before the sauna arrives

1. Build or confirm the foundation: a stable, level base with enough capacity to carry the sauna. Topture suggests a concrete pad, a compacted paver base or a reinforced deck. A level base is what keeps the glass door operating correctly.
2. Check drainage at the site. SaunaLife's instructions warn against constant water exposure to the wooden components.
3. Choose the heater package and have your electrician review its requirements before delivery day.
4. Plan how the crated components move from the curb to the build site — see delivery below.

Finishing and first use

SaunaLife strongly recommends treating all wooden components with a wood preservative, and applying it again at least once a year to improve resistance to dirt and moisture. Wood preservative is not supplied with the G2, so order it with the sauna or have it ready for assembly day. The first heating should be done under supervision, running for two hours with the sauna well ventilated, which lets the wood take up the finish and form a protective layer. Follow the first-heating instructions supplied with both the sauna and the heater, never run the heater above its maker's maximum temperature, and contact Topture if the two sets of instructions differ.

Thermally treated and kiln-dried sauna timber moves with heat and humidity. SaunaLife's own owner guidance says wood may crack or warp slightly with temperature fluctuation and that this is normal in a sauna, so the G2 is maintained rather than left alone: re-treat the surfaces yearly, check the bench and support fixings for screws loosened by heat cycling, and keep pressure washers and varnishes away from the timber.

How is the SaunaLife G2 delivered?

The SaunaLife G2 ships by LTL freight and is delivered curbside, with the shipment lowered to ground level on a pallet. The G2 is not one of the models SaunaLife flags as too long for the driver to lower — that exception applies to the longer G3 and G4 crates, not to this one. The listed shipping weight is 1,200 lbs in a single crate, and a delivery appointment is required.

The carrier will reach out to book the appointment once the shipment reaches their local terminal, and someone needs to be there to inspect and sign for it. The sauna arrives protected on a wooden pallet, sometimes encased in wood.

Inspect and photograph the shipment before you start assembly. SaunaLife's warranty does not cover damage — transport damage included — that would have been detectable by visual inspection before installation, so documenting the crate at delivery is what keeps both the freight claim and the warranty open.

Where is the SaunaLife G2 installation manual?

The SaunaLife G2 installation manual is available before you order, so your electrician and installer can review the parts list, the build sequence and the on-site cuts in advance.
