Pen and ruler Overview & What's Included Plus

Why people actually buy our saunas: the long game.

Regular sauna use is one of the most-studied longevity habits in the world. Researchers followed 2,315 middle-aged men for 20 years and found that those who used a sauna 4–7 times a week had 40% lower all-cause mortality and 50% lower fatal cardiovascular disease than once-a-week users (Laukkanen et al., JAMA Internal Medicine, 2015); a follow-up reported a 65% lower rate of Alzheimer’s disease (Age and Ageing, 2017). The benefit tracked with frequency — which is the entire argument for owning a sauna instead of booking one. The Matterhorn is built to make that frequency effortless: room for three, with the most generous indoor footprint we build.

Matterhorn — The 3-person, in red cedar with dual red light.

The Matterhorn pairs three-person space with two medical-grade red-light panels and full-spectrum infrared — all in premium Canadian red cedar. A dedicated 240V circuit drives deep, even heat to a real max of 150°F.

Included free with every Matterhorn

  • Lifetime Peak Wellness Club membership — $588/yr value. Guided daily sessions, 30-day programs, an expert research library, and session tracking — free for life.
  • Free delivery, shipped in a custom protective crate.
  • Limited lifetime warranty + lifetime U.S.-based support.
  • $3,598 value — two medical-grade red-light panels, included standard.
  • Peak Welcome Box to start your practice from day one.

Medical-grade red light, where it works. Two medical-grade red-light panels across the front wall — not a decorative strip — positioned for full-body coverage while seated, and designed to support skin, circulation, and recovery.

360° full-spectrum infrared heat. A hybrid of carbon FAR panels plus halogen + quartz emitters delivers near, mid, and far wavelengths (700–25,000nm) for even, full-body warmth — built to support deep relaxation and recovery.

Max 150°F+. Reaches 150°F — hotter than the many infrared models capped at 140°F — for a deeper, more satisfying sweat.

Run it from your phone. Preheat from anywhere; adjust temperature, lighting, and session length in the Peak Saunas app (iOS & Android).

An atmosphere for the ritual. Two HiFi Bluetooth speakers, dual-level LED accent lighting, built-in chromotherapy, and a smart oxygen-ionization system that freshens the air during and after each session — plus a foot-reflexology heater for head-to-toe warmth.

Built to last. Hand-finished Canadian red cedar — naturally aromatic, moisture-resistant, and built to last. Clasp-together assembly. Installs on a dedicated 240V circuit (professional installation recommended).

Order your Matterhorn today — and start the habit the research keeps pointing to.

Love Health benefits & the research Plus

What the research actually shows

Regular sauna bathing is one of the most-studied longevity habits in the world. The strongest evidence comes from a 20-year Finnish cohort study that followed 2,315 middle-aged men and compared those who bathed 4–7 times a week against once-a-week users.

  • Longevity. 40% lower all-cause mortality among the most frequent users (Laukkanen et al., JAMA Internal Medicine, 2015).
  • Cardiovascular. 50% lower fatal cardiovascular disease in the same group (same study); a later analysis also linked frequent sauna use to lower incidence of hypertension (American Journal of Hypertension, 2017).
  • Brain health. 65% lower rate of Alzheimer’s disease and dementia among the most frequent users (Age and Ageing, 2017).
  • Recovery and relaxation. Heat exposure raises circulation and is widely used for post-exercise recovery, muscle relaxation, and winding down at the end of a day.

Two things worth knowing about this research. It studied sauna bathing generally — largely traditional Finnish saunas — so it is evidence about the habit, not about any one brand. And the benefits tracked with frequency: 4–7 sessions a week, not the occasional visit. Consistency at that level is difficult to buy by the session, which is the practical case for owning one.

Peak saunas are wellness products, not medical devices, and are not intended to diagnose, treat, cure, or prevent any disease.

Love My New Peak Sauna

Using it everyday and LOVE it! The infrared heat and the red light Therapy are amazing with the deep penetrating heat working deep into the tissue and joints, definitely affecting the the muscles/joints and the sciatica that I am currently dealing with!

Debbie, thank you so much for the kind words. We’re so happy to hear you’re using your Matterhorn every day and getting real relief. That deeper infrared heat paired with red light can be great for loosening tight muscles and helping you stay more comfortable while you work through things like sciatica.

If you ever want tips on session length, stretching ideas to do before or after, or ways to make it even more comfortable while you heal, just let us know. We’re always here to help. Enjoy your daily sessions!

My new Matterhorn sauna

I can not say enough good about my experience. My wife and I did extensive research before buying and looked at multiple different companies. I think what stood out most about Peak is when I asked for them to give me a comparison between their sauna and a more mainstream unit. In the comparison not once did they have anything negative to say about the other brand. I made the decision right then to choose Peak! From ordering through set up and delivery I was extremely impressed and would recommend their product to anyone. We love our sauna!

Thank you so much for this incredible review! We’re truly honored that your careful research led you to choose Peak — and it means a lot that our honest, transparent comparison helped earn your trust. We believe in letting the quality of our saunas and our service speak for themselves, so it’s wonderful to hear that your entire experience, from ordering to setup and delivery, exceeded expectations.

We’re so happy you and your wife are loving your new Matterhorn sauna, and we sincerely appreciate the recommendation. Enjoy every session!

Matterhorn 3 is amazing

I love my Matterhorn 3. My wife and I have used it nearly every night and we are working our way up to longer times and higher temps. The pros: It gets hot enough for us and we definitely sweat! There is plenty of room for 2 people in it, but 3 would be snug. I list this as a pro because pretty much all 3 person saunas from all manufacturers are the same but the space in here for 2 is more than enough. The color options on the lighting are great, and the location of the heaters get great coverage, including on legs and feet. The speakers are great quality and the sound we get from them is amazing! From an aesthetics standpoint, the sauna is beautiful to look at! The cons (though none are anywhere near deal breakers): The electronics regarding how to operate the lighting, such as swapping to just accent lighting and turning off the roof light, does not work as described in the manual. I have not figured out how to do this yet, but it is a minor inconvenience. Another minor issue is there is not enough room between the right red light panel and the wall to operate it properly. Once both are plugged in, you can control both at one time with the remote, but if I make adjustments on the left panel, it still seems like the right panel will only operate at default time (15 min I think) then turns itself off, while the left remains on. I just turn the right back on if needed. It would be nice if they provided angled spacers to place on the outside edge where they mount to the glass. This would angle coverage a little better toward normal seating position. This is especially true if only one person is using it, but would work better for 2 as well. It would also possibly allow for better access to the right panels controls. The floor heater gets hot...I mean hot...when you run at temps above 125-130 and I have to shift my feet off the wooden cover at times! Overall, I love this sauna and we are very satisfied with the purchase! I would recommend this sauna, but I am hopeful they can adjust the positioning of the red light panels in future builds to help others out!

Hi John,

Thank you so much for taking the time to leave such a thoughtful and detailed review — and we’re thrilled to hear how much you and your wife are enjoying the Matterhorn 3. Using it nearly every night is exactly what we love to hear.

I really appreciate the way you broke down the pros and cons. Your feedback is incredibly helpful for both future customers and for us as we continue improving each production run.

I wanted to touch on the red light panel controls since you mentioned the panels behaving differently. You can actually adjust each individual red light panel through the Peak Saunas App, or you can group them together so they operate with the exact same settings and timer. That should eliminate the issue of the right panel defaulting back to its fifteen minute shutdown. I’ll have our support team send you step by step instructions so everything works exactly the way you want it to.

We’ll also include a few tips to help manage the floor heater getting extra hot at higher temps — there are a couple simple adjustments that make a big difference in comfort.

And thank you for the suggestions on angled spacers and red light panel placement. Feedback like this directly informs our engineering updates, and we take it seriously.

So glad you’re loving your sauna overall and getting great nightly use out of it. If there’s ever anything else you’d like us to walk through with you, we’re here for you. Enjoy every session!

Great Product, a bit glitchy, bad instructions

We had run into some issues with assembling the sauna. First, we had put the sides on wrong, as the panel was labeled "left side" and "right Side" and we thought it was as you were looking at the sauna but in reality it was while you were sitting in the sauna looking out. That took a while to figure out. Also, the bench seat wobbles and is not stable at all - so customer service sent a part that is supposed to stabilize the bench but there are no instructions on how to install it. We were also unaware that the power cord comes out of the front of the roof, not the back, so the outlet we installed is not high enough on the wall and we had to snake the cord under the roof in order for it to reach the outlet. This creates a gap in the roof that you can notice. It would have been great to know that in advance and we could have placed the outlet higher on the wall. In addition, the speaker system to connect to the phone worked great for the first use, but has not worked since. I have tried everything but I guess I have to call them again when I get a minute. All in all I had to call them a bunch of times and they were very helpful and responsive but I would prefer not to have to call at all. We have been using the sauna on a regular basis now and it is indeed helping us with sleep and overall wellness. It heats up quickly and effectively and are happy with how it works, just not happy with the wobbly seat, gap in the roof due to cord, and a glitchy bluetooth connection

Hi Amanda, thank you for sharing your detailed feedback. We're glad to hear that you're enjoying the sauna and it’s helping with your wellness! We aappreciate the feedback on the assembly challenges and the issues with the seat, cord, and Bluetooth connection. Your suggestions about clearer instructions and product design are valuable, and we'll pass them along to our team. Please don’t hesitate to reach out if you need further assistance—your comfort is our priority. Thanks again for your honest review!

How do you use the essential oils? I haven't got that figured out yet. If you could shoot me an email let me know. I would appreciate it.

Hi Melinda, we're so glad you're enjoying your Matterhorn sauna! For essential oils, you can add a few drops to a sauna safe cup or a small towel placed inside the sauna.

Expectations met

I researched saunas for several weeks and chose the Matterhorn. The people at Peak were great to work with, answering questions and making suggestions.
The delivery process was exactly as described and the delivery truck was actually early.....when does that happen?
Assembly took about an hour and a half.
We have been using it every other day and are extremely happy.
We're glad we have a Peak Sauna and have recommended them to a few friends.

Incredible! So easy to install and an epic experience every time!

We had considered a sauna for many years but never purchased one until we ran into Peak Saunas and were impressed with the quality and design of their saunas. We purchased the Matterhorn and have absolutely loved it. First, it was incredibly easy to set up. For the complexity of the wiring, glass, and pieces, they could not have made it any easier. A few walls, and a few connections, and we had it running perfectly. We have not had a single issue with it. Everything worked exactly as anticipated. We are loving it and so appreciative of this excellent product. Highly recommend!

Thank you for your amazing review! We're thrilled to hear that you had an easy and epic experience with our Matterhorn sauna. We take pride in our quality and design, and we're glad that it lived up to your expectations. We hope you continue to enjoy your sauna for years to come. Thank you for choosing Peak Saunas!

Delivery was perfect and assembly took under an hour with 2 people. Used it yesterday for the first time and loved it. Looks great and works great. For the benefit of other buyers of this model, it comes with several bags of screws that are used/needed. Instructions aren’t the best, but fairly intuitive.

As soon as your order ships, you will receive an email with tracking information. 1-2 days prior to delivery, you will receive a phone call from the delivery team to schedule your delivery appointment.

How long is the power cord and where does it come out of the unit? Plus

The cord is approximately 9 feet long and it comes out of the top of the unit at the back in the center.

What is chromotherapy and what does it do? Plus

Chromotherapy, also known as color therapy, is a form of alternative therapy that uses colors to improve physical and mental well-being. The idea behind chromotherapy is that different colors have specific wavelengths and energy frequencies, which can influence a person’s mood, emotions, and even health when absorbed by the body. Each color is believed to have unique healing properties.

  • Red: Stimulates energy, vitality, and circulation.
  • Orange: Promotes creativity, enthusiasm, and emotional balance.
  • Yellow: Boosts mood, self-confidence, and concentration.
  • Green: Known for its calming and balancing effects, aiding in relaxation and stress relief.
  • Blue: Soothes anxiety, promotes calm, and helps with sleep disorders.
  • Indigo: Encourages deeper levels of relaxation and introspection.
  • Violet: Supports mental clarity and spiritual awareness.
What is red light therapy and what is it good for? Plus

Red light therapy uses low wavelengths of red or near-infrared light to penetrate the skin and stimulate cellular repair, boost collagen production, and reduce inflammation. It’s commonly used for improving skin health (anti-aging, wrinkles), speeding up muscle recovery, relieving pain, and enhancing circulation. It’s also beneficial for wound healing, hair growth, and even improving sleep and mood by supporting cellular energy production and reducing stress on the body.

What is the difference between medical-grade and non-medical grade red light therapy? Plus

When it comes to red light therapy, not all saunas are created equal. Many competitors advertise “red light therapy” but use non-medical grade lights that offer little to no real health benefits—often serving more as decorative lighting than functional therapy.

With Peak Saunas, you’re getting true medical-grade red light therapy—the same standard used in clinical treatments for pain relief, skin health, and inflammation reduction.

When you invest in a sauna for your health, don’t settle for decorative red lights that don’t work. Choose Peak Saunas with medical-grade red light therapy for clinically backed results—so you can recover faster, feel stronger, and truly optimize your wellness.

Can you assemble my sauna for me? Plus

If you prefer not to assemble it yourself, we recommend hiring a local handyman. Thanks to the simplicity of our sauna kits, any handyman team can easily complete the setup with no prior experience required. 

What is the difference between Hemlock wood and Red Cedar? Plus

Both Hemlock and Red Cedar are excellent choices for saunas, but they offer distinct characteristics that cater to different preferences and needs.

Hemlock Wood is a light-colored, non-aromatic wood known for its smooth texture and durability. It’s an affordable, versatile option that stays cool to the touch and resists warping, making it ideal for those who prefer a clean, neutral aesthetic without strong scents.

Red Cedar, on the other hand, is a premium wood option with a rich, warm tone and a naturally pleasant aroma that enhances the sauna experience. While it comes at an additional cost, Red Cedar offers unique benefits that justify the investment:

  • Natural Antimicrobial Properties: Cedar contains natural oils that make it highly resistant to mold, mildew, and bacteria—crucial in a high-humidity environment like a sauna. This means easier maintenance, a longer-lasting structure, and a cleaner, healthier space.
  • Superior Durability: Cedar is less prone to cracking and warping over time, ensuring the longevity of your sauna.
  • Aromatic Experience: The natural scent of cedar adds a calming, spa-like ambiance to your sauna sessions.

In short, if you’re seeking a premium sauna experience with added durability, low maintenance, and natural antimicrobial protection, Red Cedar is worth the extra investment. If you prefer a more budget-friendly, scent-free option with reliable performance, Hemlock is an excellent choice.

Can I put an indoor sauna outside on a covered patio or lanai? Plus

Yes, as long as it's not exposed to sun and rain directly. If you don't plan to put it under a covered patio or something similar, we recommend getting our custom outdoor sauna cover for it and keeping it covered as shown.

Can I put an indoor sauna in my unheated garage or basement? Plus

Yes, these are some of the most common locations customers decide to put our saunas. However, when it is cold outside, the sauna will take longer than normal to heat up to maximum temperature.

How often should I use my sauna? Plus

The research points to frequency. In the 20-year Finnish cohort study, the people who saw the largest differences used a sauna 4–7 times a week; those benefits shrank at 2–3 times and largely disappeared at once a week (Laukkanen et al., JAMA Internal Medicine, 2015). Most Peak owners settle into a 20–40 minute session most days. That cadence is the entire reason owning a sauna beats booking one — it removes the drive, the schedule, and the per-session cost that quietly cap how often you actually go.

Is there real research behind sauna use, or is it just marketing? Plus

There is a genuine body of peer-reviewed research, and it is worth being precise about what it says. The most-cited work followed 2,315 middle-aged Finnish men for two decades and found that frequent sauna bathers (4–7x/week) had 40% lower all-cause mortality and 50% lower fatal cardiovascular disease than once-a-week bathers (JAMA Internal Medicine, 2015), with a follow-up reporting a 65% lower rate of Alzheimer’s and dementia (Age and Ageing, 2017). Those studies looked at sauna bathing as a habit — mostly traditional Finnish saunas — not at any particular brand or at infrared specifically. We think the honest version is more useful than the hyped one: the habit is well studied, and our job is to make the habit easy to keep.

How long until I feel a difference? Plus

Most people notice the short-term effects — deep relaxation, looser muscles, easier sleep that night — within the first few sessions. The longevity research above is about something different: a habit sustained over years, measured across decades. Both matter, and they are not the same claim. Start with sessions you enjoy enough to repeat, and the frequency takes care of itself.
