Sun Home Luminar Review: Outdoor Infrared, No Cover
Sun Home Luminar review: an aluminium-clad infrared sauna built to live outdoors uncovered. Owners report 170°F, 15-minute heat-ups and a much higher total cost than planned.

The Sun Home Luminar is the best infrared sauna for outdoor use. Owners report it heats in about 15 minutes, reaches 170°F and survives years uncovered, but plan for a 240V circuit, a level pad and a total bill well above the sticker price.

- An infrared sauna that lives outdoors with no cover

The Sun Home Luminar is a full-spectrum infrared sauna with an aluminium exterior built to sit outdoors year-round without a roof or cover. It reaches 170°F. As of October 2026, it’s the only infrared sauna we found designed for uncovered outdoor use, which is why it’s our pick for the best outdoor infrared sauna. It’s also one of the most expensive saunas on our lists once you add installation.
Is the Sun Home Luminar worth it?
The Sun Home Luminar is worth it if you want infrared heat outdoors and don’t want to build a shelter over it. Owners describe it as hot, fast and good-looking. The catch is cost: it starts around $11,000, and one owner says the full project came in at roughly four times what they’d planned.
Great for
- Backyards with no covered space for a sauna
- Buyers who prefer infrared’s gentler air temperature to a traditional sauna
- Couples (the 5-person suits two to three adults comfortably)
Skip it if
- You can place a sauna indoors or under cover. Indoor cabins like the Sun Home Equinox cost about half as much.
- You want steam and hot rocks. A traditional outdoor sauna like the SaunaLife CL5G delivers that for less.
Heat and performance
The Sun Home Luminar is one of the hottest infrared saunas available. Two full-spectrum and seven far-infrared heaters surround the bench, sit under it and run through the floor. A Luminar 5-person owner in the Monterey Bay area says it’s ready in about 15 minutes at ambient temperatures in the 60s°F, and that it “gets seriously hot” with a dry heat they prefer to traditional saunas. Another owner says theirs “regularly hits ~170°F”.
The insulation impresses owners too. One reports the cabin was still 20°F warmer than outside 24 hours after their last session.
Size, power and installation
The Luminar 2-Person measures 57″ W × 51.5″ D × 83″ H and weighs about 870 lb. The 5-Person is larger and heavier. Both need dedicated 240V power:
- 2-Person: 240V, 20A
- 5-Person: 240V, 30A (NEMA L6-30 plug)
You’ll need a level base. The California owner set theirs on pavers. Assembly is manageable “if you’re reasonably mechanical and have some help”, according to one owner, but the walls, floor and ceiling panels are heavy.
Build quality and durability
The Sun Home Luminar pairs an aerospace-grade aluminium shell with a Canadian red cedar interior. That aluminium cladding is what lets it live outside uncovered. Sun Home confirmed on Reddit that the cover paperwork shipped with one unit was outdated, and that the Luminar can be used 24/7 with no weather cover without voiding the warranty.
The best durability evidence is an owner who has kept a Luminar 5 outdoors for two years and says it “still looks and works like brand new”. Sun Home is a young brand (founded 2021), so longer-term data doesn’t exist yet.
Features and extras
- Red light therapy add-on (sold separately)
- Bluetooth speakers and an app. One 2-Person owner had trouble pairing the app, and Sun Home support offered help.
- Chromotherapy lighting
- Large glass front for views
What owners say
Luminar owners are among the most enthusiastic sauna buyers we found, though a few praise posts read as promotional, so we’ve used only detailed first-hand reports:
- Heat and speed: “ready to go in 15-ish minutes” and “absolutely cooks”, reaching about 170°F.
- Daily use: the California owner and their partner used it “pretty much every day” for the first two months.
- Weather: two years uncovered outdoors with no problems.
- Cost shock: “easily 4x more than I had planned to spend” once the pad, electrical work and extras were added.
- App: pairing problems for at least one owner.
- Electricity: owners worried about their bills, especially in high-rate areas like PG&E territory. Budget accordingly.
Warranty and customer service
Sun Home lists a limited lifetime warranty on the Luminar, while some reviews list 6 years on heaters. Check the current terms. Owners describe Sun Home’s support as responsive, including a dedicated rep who guided one buyer through installation and replaced a part.
Price and total cost
| Cost | Typical amount |
|---|---|
| Luminar 2-Person | About $11,000–$11,600 |
| Luminar 5-Person | About $13,900–$14,500 |
| 240V circuit to the yard + permit | $500–$2,500 |
| Level base (pavers or pad) | $500–$2,000 |
| Red light add-on | Optional |
| Typical total (2-Person) | $12,000–$16,000 |
Sun Home Luminar vs SaunaLife CL5G
The SaunaLife CL5G is a traditional thermo-spruce cube with hot rocks and steam, for about $6,000 plus a heater. It’s cheaper and gives a classic Finnish sauna experience. The Luminar wins on convenience (no heater to buy, no roof to maintain) and on infrared’s faster, gentler heat. Read our SaunaLife CL5G review.
Final verdict
The Sun Home Luminar is the infrared sauna to buy if it has to live outside. Owners love the heat, the speed and the looks, and the aluminium shell has survived years uncovered. Just budget realistically. The sticker price is the beginning, not the end.
