SaunaLife CL4GB: a cube sauna for a shallow spot along a fence
The SaunaLife CL4GB is a three person outdoor cube sauna kit. It measures 80.7 inches wide but only 49.2 inches deep, a shape that suits a shallow spot along a fence. Inside, one long bench gives you room to sit together, with a backrest and a footrest for support. The bronze tinted glass front and door let you look out into the yard. The B version includes black exterior paint that you brush on yourself. The paint expands and contracts as the weather changes to keep the black finish from cracking.
A shingle roof kit and ventilation come in the box. The included white LED light bar works with a Wi-Fi app or the handheld remote. The heater is sold separately, so choose one of the 4 electric heater packages on the page, from 6 to 8 kW, each with its control and stones. You can also add a Kolo bucket and ladle or wood care supplies. Need more seating room? See the SaunaLife CL5GB cube sauna. The SaunaLife CL4GB ships from Norse Steam by flat rate freight with No Sales Tax (except WY) and our 100% price match guarantee.

Barrel Sauna Collection
Cube-Series Saunas
Premium materials are evident throughout the Cube-Series lineup. The exterior is built from durable, full-length Thermo-Spruce staves that have been organically thermally enhanced, making them stronger, more dimensionally stable, and naturally resistant to decay and pests without chemical treatment. A complete shingle kit with drip rails ensures effective water management. The bronze-tinted 8mm tempered glass front door is both a design statement and a safety feature.
The CL3G specifically uses 42mm Thermo-Spruce staves for the side walls and 28mm panels for the front and back, with stainless steel barrel bands that cinch the structure together without exposed fasteners- the same joinery approach used across SaunaLife’s broader CL-series lineup. The kit includes foundation cradles, so the sauna sits level on a gravel pad, pavers, or a small concrete slab without requiring a poured perimeter foundation.

FAQ
What does the B in the model name mean, and do I have to paint it myself?
The B means the SaunaLife CL4GB includes two containers of black exterior paint, and yes, you brush it on yourself after assembly. Follow the paint manual on the Manual tab and apply it only outside, never inside the hot room. The paint stretches and shrinks with the weather to prevent cracking, but it will need a fresh coat over the years to stay black.
Does this sauna come with a heater, and what size should I pick?
No, a heater is not included. The four electric heater packages on this page range from 6 to 8 kW and each includes controls and stones. Pick one when you order or buy one later, choosing a higher kW option for a colder climate.
What electrical work does it need?
Your setup depends on the heater you choose, but every package on this page needs a licensed electrician to hardwire its own dedicated 240 volt circuit and determine breaker and wire sizing from the heater manual. These heaters cannot plug in, share a dryer, hot tub, or EV circuit, or use extension cords. Outdoor runs use buried conduit and a weatherproof disconnect, and the LED power unit mounts outside the hot room in a weatherproof box you provide.
What do I put under it? Can it go on a deck?
Yes, if your deck is built to carry the weight, or use a firm, flat, level concrete slab or compacted gravel topped with pavers. Check your deck's load capacity using the 1,415 pound shipping weight in the Specifications tab as a starting point. Avoid bare grass or soil, which holds moisture against the wood, and keep the base level so the staves line up and the door latches.
How long does it take to build?
Plan on a full weekend for a first build, based on owner reports. SaunaLife rates its cube kits for two people, and hanging the door is the step to take slowly. The electrician's visit is a separate day.
Does the glass front lose heat in winter?
Yes, the glass front loses a little more heat in deep cold, though the sauna is built for year round outdoor use. In freezing weather, heating often takes 45 to 90 minutes instead of 30 to 45 minutes. Keep the vents clear.
How many people really fit?
Three people is the maximum seated capacity on the single bench, which measures 76 inches wide by 17.7 inches deep. Plan on one or two people if you want room to stretch out or lie down.
What is thermo spruce, and does it smell like a sauna?
Thermo spruce is Nordic spruce treated in a kiln with heat and steam so it absorbs less moisture and moves less with the weather. It has a mild toasted smell and no resin, rather than cedar's strong aroma. Bare wood weathers to a silver gray, but this model uses black paint as its exterior finish.
How is it delivered?
It arrives by freight truck on a wooden pallet, by appointment, with curbside delivery only. The driver lowers the pallet to the ground, so have two or three people ready to carry the pieces to your building spot. Inspect the crate before signing and note any damage on the receipt.
