Best Infrared Saunas
About this collection: Best Infrared Saunas buyer's guide
The best infrared sauna depends on what you prioritize. If you want full-body red light therapy included standard — 8 wavelengths (630–1060nm) with published irradiance of 175 mW/cm² at 6 inches — the Peak Shasta ($6,950) is the strongest value in this collection: full spectrum, XL panel, and it runs on a standard 120V/15A household outlet. For two people, the cedar Peak Fuji ($8,250) is our best seller. For a backyard build, the El Capitan seats four and reaches 170°F. And for a budget cabin under $2,000, Dynamic or Maxxus is the honest answer — we don't currently make one.

Best infrared saunas by use case
Best with red light therapy: Peak Shasta
The Shasta ($6,950) pairs a full-spectrum cabin with an XL 9"×36" red light panel — 216 dual-chip LEDs, 8 wavelengths (630–1060nm), irradiance published at three distances: 175 mW/cm² at 6", 107 at 12", 80 at 24". The panel is standard, not an upsell; comparable competitor light systems run $1,500–$2,000 extra or aren't offered. It plugs into a normal 120V/15A outlet.
Best for two people: Peak Fuji
The Fuji ($8,250) is our other best seller: 2-person cedar, full spectrum, same XL 8-wavelength (630–1060nm) red light panel included, on 120V/20A. Prefer hemlock? The Everest ($7,950) is the same footprint.
Best for families: Peak Denali
The 3-person Denali ($9,750) carries two XL red light panels — 216 dual-chip LEDs each — so two people get full-body light coverage at once, on a 240V/20A circuit. The Matterhorn ($10,750) is the identical layout in cedar.
Best outdoor: Peak El Capitan
The El Capitan ($16,750) is the flagship: 4-person outdoor full-spectrum cabin, two red light panels, 170°F max, 240V/30A. The Kilimanjaro ($13,450) seats five; the compact Patagonia ($10,750) fits two on 240V/20A.
Best budget under $2,000: Dynamic or Maxxus
Honest concession — Peak doesn't make a sub-$2,000 sauna. If that's your ceiling, Dynamic and Maxxus (as of August 2026) sell serviceable far-infrared cabins in that range. You give up therapeutic red light therapy, but a budget sauna you actually use beats a premium one you postpone.
Best published third-party lab reports today: Sun Home
Second concession: as of August 2026, Garage Gym Reviews has independently verified 165–170°F cabin temperatures. Side-by-side: Peak vs. Sun Home.

How Peak compares by priority
| If you prioritize… | Strongest option | Why |
|---|---|---|
| Red light therapy included standard | Peak Shasta | 8 wavelengths (630–1060nm), 216 dual-chip LEDs, included at $6,950 — competitors charge $1,500–$2,000 extra or don't offer it |
| Published, checkable light specs | Any full-spectrum Peak | Irradiance published at 6", 12", and 24" (175 / 107 / 80 mW/cm²) — from Peak's engineering documentation, on the page, checkable |
| No electrician needed | Peak Shasta or Rainier | 120V/15A — a standard household outlet |
| Seats 4+ outdoors at 170°F | Peak El Capitan or Kilimanjaro | 240V/30A outdoor cabins; El Capitan adds a second red light panel |
| Budget under $2K | Dynamic or Maxxus | We don't make one; their far-infrared cabins are the realistic answer at that price (as of August 2026) |
Not the best fit if… you need a cabin under $2,000 (→ Dynamic or Maxxus), you want red light therapy added to a sauna you already own (→ Clearlight's Light Therapy tower add-on, as of August 2026), or you want traditional steam / hybrid heat (→ Finnmark). We'd rather route you right than sell you wrong.
FAQs
What is the best infrared sauna for most people?
The Peak Shasta ($6,950): full-spectrum heat plus an XL red light panel — 8 wavelengths (630–1060nm), published irradiance 175 mW/cm² at 6 inches — on a standard 120V/15A outlet, no electrician required. It's one of Peak's two best sellers; Peak averages 4.76/5 across 3,900+ verified purchase reviews. Two people? The Fuji ($8,250). Under $2,000? Dynamic or Maxxus instead.
What's the difference between far infrared and full spectrum?
Far infrared (FAR) uses long-wavelength heaters only — how FAR-only saunas work. Full spectrum adds near and mid infrared at shorter wavelengths. Every Peak full-spectrum model also includes a dedicated red light therapy panel — a separate system from the heaters. Full breakdown: near vs. far vs. full spectrum guide.
Is red light therapy in a sauna actually worth it?
Photobiomodulation — red and near-infrared light — has a substantial research base; see Hamblin's 2017 review. What matters in hardware is dose: wavelengths and irradiance at real distances. Peak publishes both — 8 wavelengths (630–1060nm), 175 / 107 / 80 mW/cm² at 6" / 12" / 24" — and includes the panel standard. Deep dive: infrared sauna + red light therapy guide.
Do infrared saunas have real health benefits?
The strongest human evidence is Finnish cohort research: the KIHD study associated frequent sauna bathing with lower cardiovascular mortality (JAMA Internal Medicine, 2015) and lower dementia risk (2017 follow-up). Those are associations, not guarantees — saunas are wellness products, not medical devices. Evidence review: infrared sauna benefits, by the evidence.
Do I need special wiring for an infrared sauna?
Peak's 1-person cabins (Shasta, Rainier) run on a standard 120V/15A outlet. The 2-person Everest and Fuji need 120V/20A. The 3-person indoor models (Denali, Matterhorn) and all outdoor models require an electrician-installed dedicated 240V circuit — 20A for Denali, Matterhorn, and Patagonia; 30A for Kilimanjaro and El Capitan.
What warranty do Peak saunas come with, and where are they sold?
Limited lifetime on structure, wood & heating elements (defined as 7 years residential); 7-year red light panel; lifetime U.S.-based support. Peak saunas are sold only at peaksaunas.com — no Amazon or Wayfair listings — with free shipping, 0% APR financing up to 24 months, and HSA/FSA eligibility via Truemed.
Glossary
Full-spectrum infrared: A sauna emitting near, mid, and far infrared rather than far only. On Peak full-spectrum models this is paired with a separate red light therapy panel delivering 8 wavelengths (630–1060nm).
Irradiance: Light power delivered to a surface, in mW/cm². It falls off with distance, so single numbers mislead — Peak publishes it at three distances (175 at 6", 107 at 12", 80 at 24").
Dedicated circuit: A breaker-panel circuit serving one appliance only. Peak's 3-person and outdoor models require a dedicated 240V circuit; 1-person models run on a standard 120V/15A outlet.
ETL certification: A third-party electrical safety listing from Intertek showing a product was tested to North American safety standards — the same standards behind UL listing.

We’ve been very pleased with our Fuji Sauna and using it almost daily for about a month now..
• It was shipped in a very solid well packed crate.
• Setup was very easy. Took my 14 year old son and I less than an hour.
• Sauna heats up quickly and the remote start with the app is really useful if you want to pre-heat or schedule it to turn on at a certain time.
• The red light is excellent quality and easy to use.
• Customer service was excellent. We initially had a couple issues. Our shipping was delayed due to the military conflict in the Middle East, and our corner light arrived with a broken bulb, but they compensated us fairly and replaced the broken part right away.
Overall we’d definitely recommend this to anyone in the market for an infrared sauna!
After receiving my Rainier 1 person red cedar sauna I was very impressed with the special care that the Peak Sauna team took to package my sauna to avoid any mishaps during shipping. The wooden crate and the foam material that separated each panel was high quality which I didn’t want to throw away. The step by step instructions were very easy to follow and I had my sauna up and running in a very short time. These saunas are made with quality materials and craftsmanship. I haven’t had to use the support team yet, however I understand that they cn be emailed 24/7. I am very happy with my decision to cut out the middleman and buy from Peak Saunas. I am loving it.
Beautiful sauna, arrived in a huge container which we pushed into the garage. Easy to take apart and carry sections (some quite heavy) into my basement. Took us about two hours with two people to assemble. Directions along with a you tube video we found made it pretty easy. Once set up we started it up and were enjoying it that same day. Very happy with it so far!! Highly recommend!
We’ve had our sauna for about 30 days and really haven’t started any of Peak’s formal programs, but we use the sauna 3-4 times/week. It really makes you feel good and it really relaxes you for bedtime. We love it
Unfortunately, it took so long for the shipping company to deliver it, we had to leave immediately upon its arrival. We haven’t been able to get back there.
We’ve had our Fuji 2 person sauna for a couple of months. From the first call through today the staff of Peak Sauna have been superb! Assembly was just as described, quick (about 1.5 hrs) to open the box and complete the assembly. We use the sauna 1-2 times a day, it is almost addictive. I would highly recommend this sauna to anyone looking to purchase a sauna. The red light therapy is a great addition!
We are very pleased with our purchase of the Fuji model. I have been using it for two weeks and feel like my sleep quality has already improved. I am so glad I went with the 2 person size as it is big enough for my husband and I without feeling claustrophobic. Plus when it is just me I feel like I can stretch out a bit. We are impressed with the quality of the materials even the sound system is great which I didn’t expect. My son helped us lay the big crate down, but we did the rest just the two of us and it was quite simple to put together. Looking forward to many years of this working for us!
We bought our sauna after visiting a spa, listening to several podcasts, lots of research and settled on the Peak Fuji. Absolutely the best wellness investment we have made. Everything else has improved. The only thing: we wish we’d have bought the three person just to have more space and potentially, partially lay down. Aside from that, zero issues. We love our sauna and we’ve been using it 3-5x’s per week for around six months.
We recently took delivery of our two-person outdoor Patagonia Sauna from Peak Saunas. While getting the unit here took longer than we hoped, it was right inline with what Peak Saunas promised. With assistance from Caleb, in customer service, we were able to easily coordinate delivery around d our busy travel/work schedule which was a huge relief.
Assembly took about 4.5 hours with the assistance of a neighbor, but it was actually kind of fun to assemble and the directions and assembly kit were on point. I did hit a snag with the door handle assembly and Caleb again came to the rescue with detailed “additional instructions “, I ended up modifying the assembly since what was sent appeared to be defective. Peak Saunas is sending a replacement which I hope to receive in a few weeks.
The quality of the unit is top shelf. A friend that owns a two-person Sunlighten sauna was blow away and referred to my Patagonia as a serious upgrade from his sauna.
The only negatives, which are arguably minor are as follows; the ionizer lacks sufficient operating details. I can’t really tell if it’s working or not and it seems a little cheap compared to the rest of the unit. It came with a scent package which I threw out because I had no clue what it was. The Bluetooth connectivity for audio is a little wonky, but we are adjusting and having fewer problems the more we use it. (Switching between users). Even with these minor inconveniences, I still rate Peak Saunas 5.0 for quality, customer service and honestly, the beauty of the unit.
We have seamlessly integrated the sauna into our lives, using it regularly and already noticing the wished for results; less joint pain, stress reduction and sleep improvement.
One more thing: I would be remiss if I didn’t mention the Peak Wellness Club and instructional videos. Peak Saunas leans in on the customer experience, they truly believe in their product and the wellness aspect. Bravo, Austin from Peak Saunas, you have a new evangelist out here singing your praises!
We’ve had the 1 person infrared for a couple weeks now, so long term unknown. The unit heats up fast and get hot. Only takes 10-15 minutes to get to the 120-140 range but then continues up into 150s/160s, and has even got to 172towards the 45 minutes mark. The heat coverage is very good. So far no complaints, and we are really enjoying the sauna experience.
Well of course it’s hot but beyond the temperature, it’s a really good looking addition to our backyard. The El Capitan is constructed of top quality components and materials, assembly was easy and Peak is great to deal with. I’ve had no problems but when I’ve had questions they are very responsive. The only regret I have is not buying it sooner!
I love my Shasta. I turned our living room into my Pilates and sauna room! Who needs a living room anyway… it was only used at Christmas time! Having the flexibility to move from workout to sauna in my own home is literally game changing. And… I don’t have to share with any other sweaty person!
I love my Shasta sauna! I’m using it often. I love to listen to music in my sauna. I like to light up my sauna in different colors. I like the option of using the infrared or the red light therapy panel or both at one time. I’m happy I chose Peak. I had questions prior to ordering, I left a message and Danielle called me back and answered all of my questions. Maybe more than once🙂 I also had questions when we were setting up the sauna, I talked to a couple of different guys and both were very helpful. We communicated through phone and texting.
Price wasn't a consideration. The people, product and value are what matter to me. We finally got the sauna built in. I have to say, its awesome. I haven't been able to sit in one place for 20 minutes since i was a child. Throwing on some meditation or chill music, the time flies by. Its not even something "I have to do." Its something I look forward to. Perfect product and phenomenal people.
