As someone who’s spent over a decade testing and reviewing saunas, I know what separates the exceptional from the average.
I spent 60 days testing the Sun Home Saunas Luminar 5-Person Infrared Sauna through scorching summer days and cool winter evenings.
With its 15 infrared heaters promising deeper muscle relief, stress reduction, and improved sleep, combined with smart app controls and stunning design, I wondered if this outdoor sauna could deliver on its ambitious promises.
After weeks of testing, sweating, and recovery sessions, what I discovered might surprise you.

About Sun Home Saunas & The Luminar Series
Sun Home Saunas has built a reputation for innovation in the wellness space, stacking their product line with infrared saunas, infrared sauna blankets, cold plunge tubs, and red light therapy devices.
Their focus on premium materials and cutting-edge technology has earned them recognition from Sports Illustrated and other major publications.
The Luminar series represents their flagship outdoor saunas, available in two sizes. The 5-person model I tested offers the most spacious sauna design, while the 2-person Luminar provides the same premium features in a more compact footprint.
The Sun Home Luminar Outdoor 5-Person Full Spectrum Infrared Sauna sets itself apart with full-spectrum infrared technology packed into 15 strategically placed heaters. While most outdoor saunas offer basic heating elements, this one delivers near, mid, and far infrared waves for maximum therapeutic benefit.
Plus, it’s the only outdoor infrared sauna featuring both aerospace-grade aluminum construction and carbonized cedar wood interior.

Design & Construction: What You Actually Get
The Luminar’s build quality impressed me from day one.
1. Grade-A carbonized cedar wood: It isn’t just beautiful – it’s engineered for serious weather resistance. After facing summer storms, autumn leaves, and winter frost, it still looks brand new.
2. Material Quality & Durability: The aerospace-grade aluminum frame provides rock-solid stability. No rattles, no squeaks, just solid construction. The double-pane glass panels offer perfect clarity while maintaining excellent insulation – even on chilly mornings, the heat stays where it belongs.
3. Space & Comfort: While marketed as a 5-person sauna, I found it comfortably fits 3-4 adults. The 20-inch deep benches provide ample seating space, though lying down works better on the longer 59-inch bench than the shorter 44-inch side bench.
4. Design Elements: The panoramic glass creates an open, airy feeling that eliminates claustrophobia. The LED lighting system transforms the space – whether you’re using the medical-grade chromotherapy or just setting a relaxing mood.
One design concern? While the front heaters feature warning labels, I’d prefer additional safety barriers, especially since these panels can get extremely hot.
The Journey: From Delivery Drama to First Sweat
The Luminar arrived in a massive 6×8 foot crate that made my neighbor’s SUV look tiny.
First lesson learned? This 1,270-pound beast needs serious muscle power. I rounded up five friends, promised them pizza, and still felt underprepared when the delivery truck showed up.
The delivery team dropped the crate at my curb – and that’s when the real adventure began. Getting it to my backyard meant borrowing a heavy-duty dolly and creating a makeshift path with plywood sheets. If you’re thinking about this sauna, factor in either professional movers or a really solid friend group.
Assembly surprised me. The actual process isn’t complex – the panels are pre-built and slot together logically. But those panels are heavy. We needed two people per wall, holding them vertically while another person handled the screws. The most challenging part? The glass front panel requires extreme care and perfect alignment.
👉 Pro tip: Check out Sun Home’s Luminar setup guide before delivery – it’ll save you lots of headaches with preparation and installation.
Then came the electrical setup. The Luminar needs a dedicated 240V/30amp circuit. My electrician charged $1,400 for installation – a cost I hadn’t factored into my initial budget.
👉 Pro tip: Get electrical quotes before your sauna arrives.
The moment we powered it up made everything worth it. The 15 infrared heaters kicked in, and within 10 minutes, the temperature hit 140°F. That first session felt like stepping into a high-end spa right in my backyard.

Living With the Sun Home Luminar: Beyond the Honeymoon Phase
Living with the Luminar changed my wellness routine completely.
I started with quick 15-minute sessions but soon found myself craving longer, more relaxing experiences. Two months in, I’ve settled into a pattern of 25-30 minute sessions, typically at 150°F – though the sauna can push to 170°F if you’re after intense heat.
Power consumption proved efficient. Despite the 240V requirement, each session costs about 30 cents – comparable to running an electric oven or clothes dryer. The quick heat-up time means you’re not wasting energy waiting for temperature – hit the power button on the app, and it’s ready in 10 minutes flat.
Daily Use & Maintenance
Keeping the Luminar clean is straightforward. A quick wipe-down with a dry towel after each session prevents sweat from soaking into the wood. Once a week, I vacuum the interior and use a gentle cleaner on the glass. The carbonized cedar naturally resists moisture and bacteria, making maintenance surprisingly simple.
Weather Resistance
Through rain, wind, and cold snaps, the sauna performed flawlessly. The included protective cover provides extra weather protection, though I installed mine under a patio overhang for added security.
👉 Pro tip: In temperatures below 40°F, give it extra warm-up time to reach full heat.
Technology Integration: The Luminar’s Smart Features Worth Having
The Luminar’s tech features impressed me more than I expected. The mobile app becomes your best friend – I love starting the heat while finishing work, knowing my sauna will be perfect when I step in.
Control Systems
The app interface is clean and intuitive. You can:
- Set and adjust temperature
- Control session duration
- Manage lighting colors and intensity
- Monitor energy usage
- Schedule pre-heating sessions
Audio & Lighting Experience
The Bluetooth audio system pairs instantly and maintains solid connection quality. While not audiophile-grade, the speakers deliver clear sound that perfectly fills the space. I’ve found myself creating different playlists for different times of day – energetic beats for morning sessions and calming tracks for evening relaxation.
The chromotherapy lighting system offers genuine therapeutic value. Each color creates a distinct mood:
- Blue tones for calm and relaxation
- Red light for energy and vitality
- Green for balance and harmony
One minor gripe – the app occasionally needs reconnecting after phone updates, though this takes just seconds to fix.

My body started noticing differences within the first week. Those persistent shoulder knots from long desk sessions? They began melting away. But the real changes showed up after consistent use.
Physical Benefits

Mental Clarity & Stress Relief
The sauna turned into my thinking space. Twenty minutes of heat-induced calm helped me tackle problems with fresh perspective. My evening sessions became a stress reset button – the perfect bridge between work and relaxation.
Skin Health & Circulation
I noticed clearer, more vibrant skin after just a few weeks. The full-spectrum infrared technology seems to trigger a healthy glow that lasts. Even my chronic cold hands improved, suggesting better overall circulation.

My Verdict – Is The Sun Home Luminar Worth It?
After two months of nearly daily use, here’s my straight talk: The Luminar isn’t just a sauna – it’s a game-changing wellness investment.
For pure performance, it beats every other sauna I’ve tested. The combination of full-spectrum and FIR heaters creates an experience that feels both intense and gentle. No hot spots, no cold zones, just perfectly distributed heat.
The build quality speaks volumes. Every detail, from the carbonized cedar to the aerospace-grade aluminum frame, shows thoughtful engineering. While cheaper options might save money upfront, the Luminar’s construction suggests it’ll outlast most of its competitors by years.
After extensive testing and comparison, it’s no surprise that I ranked it as the top choice in both our best infrared saunas and best outdoor saunas guides.
Who should buy it? If you’re serious about wellness, have the space for a permanent installation, and can handle the investment, absolutely go for it. The Luminar makes sense for:
- Fitness enthusiasts wanting faster recovery
- People dealing with joint or muscle issues
- Families who’ll use it regularly
- Anyone wanting a luxury spa experience at home
Who should skip it? If you’re looking for a portable solution, tight on space, or prefer traditional steam saunas, consider other options.
