Buying an infrared sauna can feel overwhelming—there’s no shortage of options, price points, and technical jargon. And while the industry would like you to think that the most expensive sauna is automatically the best, that’s simply not true.
If you know what to look for, you can get top-tier quality, features, and results—without paying $10,000+. Here’s what to look for, and how to choose wisely.
Over 10,000 Peak Saunas Sold Nationwide
1) Pick the infrared type that matches your health goals
If you want the full range of infrared sauna benefits — from deep tissue muscle relief to skin health to improved circulation — full spectrum is the way to go. You’ll get near, mid, and far infrared working together, plus a few of our models include medical-grade red light therapy to boost energy at the cellular level, speed recovery, and support healthy skin.
What you’re deciding: Which type of infrared heat matches your goals
Full spectrum delivers the full range of infrared wavelengths—near, mid, and far—so you get the maximum variety of potential benefits. If you want all the science-backed advantages—deep muscle recovery, skin rejuvenation, joint relief, cardiovascular benefits, and more—this is the one to choose. Many of our full spectrum saunas also include medical-grade red light therapy, which boosts energy at the cellular level, supports recovery, and promotes healthy skin tone.
Far infrared focuses exclusively on far wavelengths. It still offers great detoxification, relaxation, and circulation benefits—ideal if you want the core wellness perks at a lower investment.
✅ Green flag: personalized guidance that matches your health goals to the right technology.
🚩 Red flag: brands that can’t explain the real difference between sauna types or push one option without asking about your needs.
2) Make sure the design delivers full, even heat coverage
What you’re deciding: Whether it will heat your whole body evenly and efficiently
A sauna can have the highest wattage in the world, but if the design is poor, you’ll end up with cold zones that ruin the experience.
Panel placement – Poorly designed models only have heaters on the back and sides, forcing you to constantly shift positions. Peak saunas are engineered with optimized panel layouts for full, even coverage.
Emissivity – This measures how efficiently the panels emit infrared heat. High-emissivity panels deliver stronger, more therapeutic heat.
Max temperature & heat-up time – You should expect a comfortable preheat in about 20–30 minutes.
Convenience features – WiFi and app control let you start preheating from anywhere so it’s ready when you are.
✅ Green flag: multiple heating zones, high emissivity panels, even coverage, and modern convenience features.
🚩 Red flag: cold spots, slow warm-up times, and “high power” claims that ignore real-world performance.
I started to understand why traditional sauna lovers dismiss infrared saunas as "not real saunas." Because most of them simply aren't hot enough to trigger the physiological benefits that make saunas therapeutic.
The budget Amazon units were even worse, barely reaching 120°F and emitting chemical smells that gave people headaches.
One review mentioned needing to air out their garage for days because of the toxic fumes.
I was about to give up…
3) Check if the size is truly comfortable for the number of people you need

What you’re deciding: Whether it will truly fit your needs—not just the brochure description
The sauna industry works a bit like Airbnb—when they say “sleeps 4,” two of those spots might be an uncomfortable pull-out couch. Same with saunas: a “2-person” model might only seat two if you’re squeezed in.
At Peak, our 2-person models are true two-person saunas—the largest in the industry by far—designed for real comfort.
✅ Green flag: transparent interior dimensions and realistic seating expectations.
🚩 Red flag: vague size descriptions with no usable dimensions provided.
4) Confirm it’s built for safe, clean daily use
What you’re deciding: Whether it’s safe to use every day
Your sauna should feel like the cleanest, safest place in your home.
Ultra-low EMF design – Peak saunas are built to keep electromagnetic fields at ultra-low levels for peace of mind.
Oxygen ionizer – Keeps the air fresh and clean inside, especially during longer sessions.
Wood quality – Look for furniture-grade, sustainably sourced woods that are kiln-dried and free from harsh chemical treatments.
✅ Green flag: ultra-low EMF design, built-in air purification, and non-toxic, high-quality materials.
🚩 Red flag: no EMF transparency, treated or composite woods, or no built-in air purification.
5) Choose a style and ambiance you’ll love in your home
What you’re deciding: Whether it’s something you’re proud to have in your home
A sauna is more than a wellness tool—it becomes part of your living space.
Aesthetic design – At Peak, we combine clean lines, premium wood finishes, and refined hardware for models that look better than even the “prestige” brands.
Lighting & ambiance – Multiple layers of premium LED lighting—wall, bench, and ceiling—create a true spa feel. Our integrated medical-grade chromotherapy uses targeted wavelengths for mood, relaxation, and recovery.
✅ Green flag: design that blends with your home and creates a luxury spa atmosphere.
🚩 Red flag: dated aesthetics and only a single ceiling light with basic, non-medical-grade chromotherapy.
But it wasn't just the smart features that impressed me. I noticed I was handling work pressure better and staying calm when things got chaotic.
4. My Doctor Couldn't Believe My Heart Health
At my annual checkup, my doctor actually did a double-take at my results. "Whatever you're doing, keep doing it," she said. My blood pressure and heart rate had improved more in 6 months than in the previous 5 years combined.
Turns out there's real science behind this. A clinical study with heart failure patients showed that just 15-minute infrared sauna sessions significantly improved cardiovascular function, with one group seeing dramatic reductions in heart irregularities (Beever, 2009).¹
5. I Started Looking Noticeably Younger
The medical-grade red light therapy was working in ways I could actually see. My skin became tighter, fine lines around my eyes started disappearing, and my complexion improved dramatically.
My wife was the first to notice the change. "Your skin looks amazing!" I started getting similar comments from friends and colleagues.

The customer support was the best that I have ever experienced. The sauna heats up quick and the lighting and Bluetooth systems are a very nice feature.

I received my sauna and I am ABSOLUTELY loving it! Even my husband is enjoying the benefits of using it. It was packaged very well when it arrived. It was pretty easy to put together.
If you are on the fence like I was for many months don't wait, get one asap you won't regret it! I have more energy and just overall feel better. What sealed the deal for me was the company’s lifetime warranty on the sauna.
