Saunalife Model CL4G 3 Person Outdoor Sauna

The SaunaLife Model CL4G is the middle model in the Cube-Series — a 3-person outdoor cube sauna that keeps the full-glass front and thermally modified construction of its bigger sibling while trimming the footprint to 49.2 inches deep. That depth is the reason it’s our most-recommended cube sauna: it fits on an existing patio or deck corner where the four-person CL5G won’t, but it still gives a couple genuine elbow room and seats three when friends come over. If you’re weighing the Cube-Series models against each other, this page covers what’s actually different — measured dimensions, heater sizing, and what delivery day looks like.

A Footprint That Fits Real Backyards

The Model CL4G measures 80.7″W × 49.2″D × 82.7″H on the outside — barely more than four feet deep. In practice, that means it can sit against a fence line, on a reinforced deck section, or beside a pool without dominating the yard. Inside, you still get 77.2 inches of width, 74.8 inches of headroom, and a 76-inch back-wall bench long enough to lie down on. A lower step bench doubles as seating for a third bather and as a footrest for two. If your household regularly saunas with three or more people, step up to the CL5G’s two-tier layout; for one to three bathers, the CL4G is the sweet spot.

The Glass Front Is the Whole Point

What separates a Cube-Series sauna from a barrel sauna or a shed-style build is the front wall: 8mm bronze-tinted tempered glass, floor to roofline. From inside, the expansive glass front turns the sauna session into a view — snow, garden, sunset — instead of a wooden box. From outside, the bronze tint keeps the interior private in daylight while the black-painted front details frame the glass cleanly. The door is the same tempered bronze glass, so light pours through the entire face of the sauna.

Thermo-Spruce Construction, Handcrafted in Northern Europe

The CL4G’s walls are full-length 42mm Thermo-Spruce staves, 1.7 inches thick, heat-treated rather than chemically treated. Thermal modification changes the wood at the cellular level: it becomes dimensionally stable through freeze-thaw cycles, naturally resists decay and pests, sheds splinters, and takes on a rich, darker color that weathers gracefully with almost no maintenance. Overhead, a complete shingle kit with drip rails manages rain and meltwater, and the kit includes ventilation, fascia boards, and foundation beams — details that matter after five winters, not just on delivery day. Benches and backrests are knotless, satin-smooth Thermo-Aspen that stays cool to the touch even at full temperature, with contoured seating and supportive arched backrests.

Sizing an Electric Sauna Heater for the CL4G

Like all SaunaLife rooms, the CL4G sauna kit ships without a heater so you can choose the one that matches how you bathe. For this room’s volume, most customers land on a 6–8 kW electric sauna heater on a dedicated 240V circuit, hardwired by a licensed electrician. Rock-heavy tower heaters give softer steam and hold heat between sessions; compact wall heaters heat up faster. Heater systems and accessories ordered together with the sauna often ship free on top of the room’s crate. Tell us your climate and how many sessions a week you’re planning, and we’ll spec the heater package with the right controls.

Included Wi-Fi LED Light System

The CL4G includes SaunaLife’s dotless white LED light bar system — two IP67-rated light bars running on low-voltage 24V DC, controlled by Wi-Fi app or the included wireless remote. Mounted with the articulating clips, the indirect lighting washes along the Thermo-Spruce grain and makes evening sessions feel deliberate rather than lit by an afterthought bulb. The driver supports up to four light sources if you expand later.

CL4G or CL5G? An Honest Comparison

We sell both, so here is the plain difference. The CL4G is 49.2″ deep, ships at 1,415 lbs, seats up to three, and suits couples who want a daily-driver sauna with a compact footprint. The CL5G is 63″ deep, adds an L-shaped two-tier bench, and is the better buy for families or anyone who wants to lie flat on the upper bench. Construction, glass, roof, and LED lighting are identical. If neither fits, the compact two-person CL3G rounds out the series.

Delivery, Foundation, and Assembly

The CL4G ships by freight carrier on a wooden pallet — crate size 80″W × 44″D × 41″H, shipping weight 1,415 lbs — with $950 flat-rate curbside delivery in the contiguous U.S. and $1,250 to Canada. Delivery is by appointment; the driver lowers the crate to ground level, and you’ll want a helper to move panels to the site. Prepare a level, load-bearing base first: concrete pad, pavers over compacted gravel, or a structurally rated deck. The included foundation beams, montage kit, and installation manual make assembly a methodical two-person project — precut panels, no cutting or guesswork.

SaunaLife CL4G — Frequently Asked Questions

Will the CL4G fit on my deck or patio?

If you have a level, structurally sound area of roughly 7 × 4.5 feet plus clearance for the door swing and heater service, yes. At 1,415 lbs shipping weight (plus bathers), decks should be verified for load.

What heater should I buy with it?

A 6–8 kW electric sauna heater on a dedicated 240V circuit covers this room well. We can bundle the heater, controls, and stones with your order — ask before checkout and we’ll confirm freight rides free on the sauna’s crate.

How much maintenance does Thermo-Spruce need?

Very little. The thermal modification does the preservation work — no staining or sealing is required for durability. Many owners let it weather naturally; some apply a UV oil to hold the original color.

How long does assembly take?

Plan a weekend with two people and basic tools. The kit is precut and panelized with step-by-step instructions; the shingle roof is the most time-consuming stage.

Does buying from Norse Steam affect the warranty?

No — we are an authorized SaunaLife dealer, so the full manufacturer warranty is included. Details are in our warranty guide.
