Quick Answer: Auroom’s entry outdoor cabin, the Mira S, lists at $14,990 versus Sun Home’s Luminar 2-Person at $10,999 — but that comparison is misleading on both price and product. Auroom’s price is cabin-only; per the brand’s own heater packages, a Harvia Virta unit adds $3,495-$4,279, pushing the real Auroom total past $18,000. Sun Home’s price already includes its infrared heating panels. More importantly, they’re not the same kind of heat: Auroom pairs with a traditional electric-and-rock heater reaching 180-195°F, while Sun Home’s infrared panels top out at a published 170°F. Decide on heat type first, then compare total cost — not the other way around.
Both brands show up in “best outdoor sauna” roundups for their premium, non-barrel looks — Auroom’s signature tempered-glass front wall, Sun Home’s aluminum-bodied Luminar — which makes them an obvious head-to-head search. But they’re not actually competing for the same buyer once you look past the cabin photo.
Auroom vs. Sun Home outdoor cabins, side by side
| Model | Heat type | Max temp | Capacity | Price |
|---|---|---|---|---|
| Sun Home Luminar 2-Person | Infrared panels (all-in) | ~170°F | 2 people | $10,999 |
| Auroom Mira S | Harvia electric + rocks (heater separate) | ~180-195°F | 4-5 people | $14,990 + $3,495-$4,279 heater |
| Sun Home Luminar 5-Person | Infrared panels (all-in) | ~170°F | 5 people | $13,899 |
| Auroom Aura | Harvia electric + rocks (heater separate) | ~180-195°F | 2 people | $17,990 + $3,495-$4,279 heater |
The sticker price is deceptive — Auroom’s cabin isn’t the whole bill
Sun Home Luminar 2-Person Outdoor Infrared Sauna
- Price includes the heating source — infrared panels built into the cabin walls — so $10,999 is the real total before an electrician's install work.
- Rated by Sun Home to run uncovered outdoors through winter, a weatherproofing claim Auroom's wood-and-glass cabins don't make in the same terms.
- Independently tested by Vitatech Electromagnetics at 0.5 mG at seated distance (January 2025), per Sun Home's own published results.

Auroom’s Mira S lists at $14,990, which on its face already looks more expensive than the Luminar 2-Person’s $10,999. But per our Auroom sauna review, that figure is the structure-only kit — walls, bench, glass front, door — with the heater priced separately, almost always a Harvia package. A cabin this size typically needs a Harvia Virta 10.5kW unit at $3,495-$4,279, which brings the real Mira S total to roughly $18,485-$19,269 before the 240V circuit most outdoor installs also require. The gap between Auroom and Sun Home isn’t the $3,991 the sticker prices suggest — it’s closer to $7,500-$8,300 once both brands are priced the same way: all-in.
Two different heat types wearing similar price tags
The bigger issue with a straight price comparison is that Auroom and Sun Home don’t sell the same kind of sauna heat. Auroom’s outdoor cabins pair with a traditional Harvia electric heater topped with rocks — the same convection-and-steam format covered in our infrared vs. traditional sauna guide, which reaches 180-195°F and lets you pour water on the rocks for a burst of steam (löyly). Sun Home’s Luminar uses infrared panels that warm your body directly rather than heating the room air, rated to a published 170°F ceiling — cooler, faster to warm up, and a fundamentally gentler session even before you factor in price.
That distinction matters more than the price gap for most buyers. Someone who specifically wants the classic hot-rock-and-steam sauna experience won’t be satisfied by Sun Home’s infrared heat regardless of how much cheaper the Luminar is, and someone who wants a gentler, faster-heating session won’t get that from Auroom’s traditional Harvia setup no matter how much they spend on the glass-wall look. Pick the heat type first — see our infrared vs. traditional breakdown if you’re unsure which one fits you — then compare these two brands’ real, all-in costs.
Construction and weatherproofing: aluminum vs. wood-and-glass
Sun Home builds the Luminar’s body from aluminum and markets it as rated to sit outside uncovered through winter weather, per the brand’s own product page. Auroom’s outdoor cabins (Aura, Mira S, Garda, Arti) use the brand’s signature wood construction with a tempered-glass front wall — a different material profile that Auroom’s own materials don’t claim matches Sun Home’s no-cover weatherproofing language. If an outdoor sauna is going somewhere exposed year-round without a dedicated cover or enclosure, confirm each brand’s actual warranty terms for your climate with a dealer before assuming either one is maintenance-free.
Which one fits you
- You want one number to budget against: Sun Home’s Luminar price already includes the heat source — $10,999 for 2-person, $13,899 for 5-person — so there’s no separate heater quote to chase down.
- You want the classic steam-capable 180-195°F traditional experience: Auroom is the only one of these two brands that delivers it, but budget the real $18,000+ all-in total for the Mira S, not the $14,990 cabin-kit sticker.
- You’re not sure which heat type you actually want: read our infrared vs. traditional sauna guide before comparing either brand’s price — it’s the decision that should come first.
The bottom line
Auroom and Sun Home end up in the same “best outdoor sauna” roundups because both look premium, but they’re solving different problems. Sun Home’s Luminar is an all-in infrared cabin — $10,999 covers the whole heat source, aluminum body included, rated for uncovered outdoor use. Auroom’s Mira S and Aura are traditional steam-capable cabins with the heater priced and bought separately, which per current Harvia package pricing turns a $14,990-$17,990 sticker into an $18,000-$22,000+ real total. Decide on heat type first — infrared or traditional — then compare each brand’s real all-in cost, not the cabin-kit number alone.
