SaunaLife GL4B: a black cabin with a glass front and porch

The SaunaLife GL4B is an outdoor sauna cabin kit with room for four people. Its floor to ceiling glass front and covered porch sit within a footprint about 59 by 80 inches. The B model comes with black exterior paint packed in the box for you to brush on yourself. Bronze tinted glass lets you look out from the upper and lower benches. Backrests are included, too. A light beneath the roof edge illuminates the porch. Inside, you can adjust the white LED lighting with the included handheld remote or a Wi-Fi app.

The kit includes the ground frame, roofing felt, ventilation, and drainage. Delivery comes on a pallet to your curb by freight truck, with an appointment arranged ahead of time. The heater is sold separately, so choose one of the 7 electric heater packages on the page, from 6 to 6.4 kW, each with its control and stones. You can also add a bucket and ladle or wood care supplies. Prefer an arched roof? See the SaunaLife G3B outdoor sauna pod. The SaunaLife GL4B ships from My Cozy Outdoors by flat rate freight with No Sales Tax (except WY) and the full manufacturer warranty.

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 PROSAUNAS SaunaShield black exterior sauna 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 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 seven electric packages sized for this room, from 6 to 6.4 kW, each with controls and stones. Pick one when you order or buy one later, choosing the higher kW option for a colder climate.

What electrical work does it need?

It needs a licensed electrician to hardwire the heater on its own dedicated 240 volt circuit, with breaker and wire sizing based on your chosen heater's manual and your property. 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 sit on grass or on my deck?

No to grass or bare soil, and a deck works only if it is built to support the sauna's 1,650 pound weight. Your site needs a firm, flat, level base, such as compacted gravel topped with pavers, a concrete slab, or a suitable deck. Soil holds moisture against the wood, and an uneven base can keep the wall pieces from lining up and the door from latching.

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-time builders 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 have two or three people ready 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 with heat and steam in a kiln so it absorbs less moisture and moves less with the weather. It has no resin, has a mild toasted smell, and can last up to twice as long as cedar outdoors. The black paint is this model's exterior finish, so refresh it over the years to keep it black.

Do I need a permit or HOA approval?

It depends on your local rules and HOA, but the dedicated 240 volt circuit almost always needs an electrical permit. Many towns exempt small accessory buildings from building permits while still requiring setbacks, and your HOA may have its own requirements. Check with your local permitting office and HOA before ordering.
