How much space does an outdoor sauna need?
Measure your spot before you pick a model. These are the outside sizes, weights and power needs Sun Home lists for its four outdoor saunas, with footprint worked out for you.
Size at a glance
| Model | Outside (L × W × H, in) | Footprint* | Weight | Power |
|---|---|---|---|---|
| Luminar 2-Person | 51.5 × 57 × 82.7 | about 20 sq ft | 970 lb | 240V, 20A GFCI outlet |
| Luminar 5-Person | 51.75 × 82.25 × 84 | about 30 sq ft | 1,070 lb | 240V, 30A GFCI outlet |
| Solaris 4 | 68.9 × 90.1 × 94.5 | about 43 sq ft | 1,698 lb | 240V, dedicated 30A, hardwired |

Sizes, weights and power as listed by Sun Home on October 13, 2026. *Footprint is length × width, our own arithmetic, rounded. It does not include walking space around the sauna.
Height: do you have headroom?
The Luminar models stand about 6.9 and 7 feet tall. The Solaris models are 94.5 inches, about 7.9 feet. If you plan to tuck one under a deck, pergola or tree limbs, measure the clearance first, and leave room to work around it.
Weight: what the base must hold
Spread across its footprint, the listed weight comes to roughly 33 to 48 pounds per square foot (our arithmetic, empty, and weight may not be spread evenly). People, furniture and stones add more. Sun Home says the Solaris needs a load-bearing pad rated for its full weight. Ask a local contractor what base suits your soil before delivery. We do not have a verified base specification for the Luminar, so check Sun Home's installation guide.
Power: plan the circuit first
Every model needs its own 240V circuit installed by a licensed electrician. The Luminar plugs into a GFCI outlet (NEMA L6-20 or L6-30). The Solaris is hardwired. Get the electrician's quote and the run from your panel to the sauna before you order, since distance affects cost. See what an outdoor sauna costs to run for the electricity side.
Delivery and access
- Luminar: arrives on a pallet at the curb. Plan how to move about 1,000 lb of panels to the site, and about half a day for two people to assemble.
- Solaris: delivered fully built, so you need a clear path to the pad (gates, slopes and turns) and a level base. Lead time is about 3 to 4 months.
- Clearance: Sun Home lists about 6 inches on each side for the Solaris. Check its manual for the Luminar.
Permits and rules
Some towns treat an outdoor sauna as an accessory structure, and rules vary on distance from property lines. We do not have your local rules, so ask your building department.
