SaunaLife Model CL5G 4 Person Outdoor Cube Sauna

The SaunaLife Model CL5G is the largest outdoor sauna in the Cube-Series lineup — a 4-person outdoor home sauna kit that pairs clean Scandinavian lines with a dramatic full-glass front. Where most outdoor saunas of this capacity look like garden sheds, the CL5G reads like a piece of backyard architecture: a bronze-tinted tempered glass wall up front, thick Thermo-Spruce staves on every other side, and a shingle roof to finish it off. We carry all three Cube-Series models at Norse Steam, and the CL5G is the one we point families toward — it is the only cube sauna in the series with genuine room for four bathers.

Why the CL5G Stands Out in the SaunaLife Cube Series

Every Cube-Series sauna shares the same design language — the glass front, the indirect LED lighting, the thermally modified wood — but the Model CL5G stretches the footprint to 63 inches deep, which changes how the room is used. Instead of a single bench line, you get an L-shaped, two-tier seating arrangement: a 73.2-inch lower bench, a 76-inch upper bench along the back wall, and a 17.3-inch side bench. Two people can stretch out fully, or four can sit comfortably without knees touching. The sauna is designed by SaunaLife and handcrafted in Northern Europe, and the fit of the precut components reflects that.

Room for Four Bathers — Measured, Not Marketed

Capacity claims on outdoor saunas are often optimistic, so here are the numbers. The CL5G interior measures 77.2″W × 55.1″D × 74.8″H — over six feet of headroom, which taller bathers will appreciate immediately. The upper bench is 17.7 inches deep and the lower bench 31.1 inches, deep enough to sit cross-legged or lie down. Benches and backrests are knotless Thermo-Aspen, a satin-smooth wood chosen because it stays cool to the touch at full sauna temperature, with contoured seating and arched backrests that make long sauna sessions easier on your back than flat boards.

Built to Live Outside Year-Round

The CL5G is a true outdoor sauna, not an indoor room repackaged. The walls are 42mm Thermo-Spruce staves (1.7 inches thick), thermally modified in a heat-treatment process that makes the exterior wood darker, dimensionally stable, splinter resistant, and naturally resistant to decay and pests — with no chemical treatment. A complete shingle kit with drip rails sheds rain and snowmelt away from the walls, and fascia boards and black-painted front details finish the exterior. The 8mm bronze-tinted front glass is tempered for safety and gives the interior privacy in daylight while still offering a clear view out. Owners in snow-belt states run these saunas all winter; the cold outside is part of the experience.

Choosing a Sauna Heater for the CL5G

Like every SaunaLife sauna kit, the CL5G ships as a complete room — walls, glass, roof, benches, heater guard, montage kit, and instructions — with the sauna heater sold separately so you can match it to your preferences. For this interior volume, most of our customers pair the CL5G with an 8–9 kW electric sauna heater on a dedicated 240V circuit installed by a licensed electrician. The kit includes a heater guard, and heater systems and accessories ordered with the sauna often ship free in a protective box on top of the room’s crate. If you are unsure which heater fits how you plan to bathe — fast heat-up, softer löyly, rock capacity — contact us and we will spec the package for you.

Wi-Fi LED Lighting Comes Standard

The CL5G includes SaunaLife’s premium “dotless” white LED light system rather than leaving lighting as an afterthought. Two LED light bars run on safe 24V DC low voltage with heat- and water-rated IP67 connections, controlled from a Wi-Fi app or the included wireless handheld remote. Articulating and flush mounting clips let you aim the indirect lighting to graze the wood grain, and the system expands to control up to four light sources if you want to add more later.

CL3G vs. CL4G vs. CL5G: Which Cube Sauna Fits?

The three Cube-Series models share identical construction and the same 80.7-inch width — the difference is depth and seating.

• SaunaLife CL3G — the compact cube, sized for two bathers. The right choice for couples and tight side-yard placements.
• SaunaLife CL4G — the middle model at 49.2 inches deep, seating up to three. The best seller for couples who host occasionally.
• SaunaLife CL5G — the full-size cube at 63 inches deep with two-tier L-shaped seating for four. The one to buy if more than two people will regularly sauna together, or if you want room to lie down.

Delivery, Site Prep, and Assembly

The CL5G ships freight on a wooden pallet — crate dimensions 81″W × 44″D × 42″H, shipping weight 1,680 lbs — with $950 flat-rate curbside delivery to the contiguous United States and $1,250 to Canada. Delivery is by appointment and the driver lowers the crate to ground level; from there you will want two or three people to carry components to the site. Before it arrives, prepare a level, load-bearing base such as a concrete pad, pavers, or a reinforced deck section slightly larger than the sauna’s 80.7″ × 63″ footprint. Assembly is a precut, panelized kit with an included montage kit and step-by-step installation manual — a reasonable weekend project for two people with basic tools. We typically call before shipment to walk through delivery details so there are no surprises on the day.

SaunaLife Model CL5G — Frequently Asked Questions

Does the CL5G come with a heater?

No — the CL5G is a sauna room kit, and the electric sauna heater is purchased separately. This is standard for SaunaLife and lets you choose the heater style and control system you prefer. We bundle heater packages and can recommend the right output for this room.

What kind of foundation does it need?

A level, stable, load-bearing surface: a concrete slab, compacted gravel with pavers, or a structurally sound deck. The kit includes foundation-ready construction, but the base itself is site-prepared by the owner.

Can it stay outdoors through winter?

Yes. Thermally modified Thermo-Spruce, the shingle roof with drip rails, and tempered glass are all specified for four-season outdoor exposure. Winter is when these saunas get used the most.

How is it delivered?

By freight carrier, curbside, on a wooden pallet, with a scheduled appointment. The driver lowers the crate to ground level; moving components to your prepared site is up to you and a helper.

Is the warranty included when buying from Norse Steam?

Yes — Norse Steam is an authorized SaunaLife dealer, so the full manufacturer warranty applies. See our warranty guide for details.
