SaunaLife GL4B: a narrow side yard cabin with a full glass front
The SaunaLife GL4B is a four person outdoor sauna cabin kit. At just 58.9 inches wide, it fits a narrow side yard. The floor to ceiling bronze tinted glass front lets in daylight and gives you a view outside. The B version includes black exterior sauna paint that you brush on yourself. The walls are thermo spruce, which means spruce baked in a kiln. This treatment helps the wood handle moisture without rotting and last up to twice as long as cedar. Inside, you get benches and backrests, with a covered porch outside the door.
A light strip under the eaves lights the entrance. The included white interior lighting works with a Wi-Fi app or handheld remote. The heater is sold separately, so choose one of the 6 electric heater packages on the page, from 6 to 9 kW, each with its control and stones. Need more seating? See the SaunaLife GL6B outdoor sauna cabin. The SaunaLife GL4B ships from Norse Steam by flat rate freight with No Sales Tax (except WY) and our 100% price match guarantee.

FAQ
What does the B in the model name mean, and do I have to paint it myself?
B means the SaunaLife GL4B includes two containers of black exterior paint, and yes, you brush it on yourself after assembly. Follow the paint instructions on the Manual tab and use it only outside, never inside the hot room. The paint expands and contracts with the weather and will need fresh coats over the years to stay black.
Does this sauna come with a heater?
No, the heater is sold separately. The Select Heater add on on this page offers six electric packages from 6 to 9 kW, each with controls and stones. Pick one when ordering or buy one later, choosing a higher kW option for a colder climate.
What electrical work does it need?
It needs a dedicated 240 volt circuit hardwired by a licensed electrician, with breaker and wire sizing based on your property and the chosen heater's manual. No package plugs in or allows extension cords or a shared dryer, hot tub, or EV circuit. Outdoor runs need buried conduit and a weatherproof disconnect, and the LED power unit needs a weatherproof box you provide outside the hot room.
What do I put under it? Can it sit on grass or on my deck?
Use a firm, flat, level base such as compacted gravel topped with pavers or a concrete slab. A deck may work if it is built to carry the 1,650 pound sauna, so its suitability depends on your deck's construction. Never use bare grass or soil, which holds moisture against the wood, and keep the base level so the pieces align and the door latches.
How long does it take to assemble, and how many people do I need?
Two people need about two days, according to SaunaLife's assembly estimate. The pieces are numbered, and the instructions are on the Manual tab. First timers often take longer, and the electrician's visit takes a separate day.
Can it stay outside all winter?
Yes, it is built for year round outdoor use. In freezing weather, heating often takes 45 to 90 minutes instead of 30 to 45 minutes, and the glass front loses a little more heat in deep cold. Keep the vents clear.
How is it delivered?
It arrives by freight truck on a wooden pallet, with curbside delivery by appointment. The driver lowers the pallet to the ground, so arrange two or three people to carry the pieces to your assembly spot. Inspect the crate before signing and note any damage on the receipt.
What is thermo spruce, and how do I look after the outside?
Thermo spruce is Nordic spruce treated in a kiln with heat and steam, helping it absorb less moisture, move less with the weather, and last up to twice as long as cedar outdoors. It has no resin and a mild toasted smell, and bare wood turns silver gray without affecting its function. This model uses black paint as its exterior finish, which needs fresh coats over the years to stay black.
Do I need a permit or HOA approval?
It depends on your local rules and HOA. The dedicated 240 volt circuit almost always needs an electrical permit, and even towns that exempt small accessory buildings from building permits still apply setback rules. Check with your local permitting office and HOA before ordering.
