Pen and ruler Overview & What's Included Plus

The Peak Rainier is a 1-person indoor full spectrum infrared sauna with near-zero EMF construction. It reaches a true 150°F, includes a full-body medical-grade red light panel as standard, runs from the Peak Saunas app, plugs into a standard 120V outlet, and ships free in a protective crate with a 7-Year Warranty.

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 Rainier is built to make that frequency effortless: small enough for a spare corner and plug-and-play on a standard household outlet.

Rainier — The 1-person, in aromatic red cedar.

The Rainier is our single-person cabin built in premium Canadian red cedar — naturally aromatic, moisture-resistant, and beautiful — with full-spectrum infrared, an XL medical-grade red-light wall, and a real max of 150°F. Plugs into a standard outlet.

Included free with every Rainier

  • 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.
  • 7-Year Warranty + lifetime U.S.-based support.
  • $1,799 medical-grade red-light wall — included standard.
  • Peak Welcome Box to start your practice from day one.

Medical-grade red light, where it works. Real therapy, not decorative LEDs — an X-large medical-grade panel on the front wall, positioned for full-body coverage while seated and designed to support skin, circulation, and recovery. Most brands hide a token strip in the ceiling; the Rainier puts it where it works.

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. Plugs into a standard 120V household outlet — no electrician, no dedicated circuit.

Order your Rainier 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.

Loving my decision

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.

Thank you for your wonderful feedback! We're delighted to hear you're enjoying your Rainier sauna and appreciate your kind words about our packaging and craftsmanship. We're here whenever you need us. Enjoy your wellness journey!

Very pleased

I received my sauna about two weeks after placing the order, and it arrived very well packaged in a sturdy box crate for protection. The unboxing process was simple and straightforward. That said, I would definitely recommend having a second person help with the installation and assembly it makes putting everything together much easier.

This is my first time ever owning a sauna, and so far I’ve been very pleased with it. It heats up relatively fast, which has been great for fitting sessions into my schedule. I’ve also really appreciated the red light therapy feature, it feels like a valuable addition to the overall experience.

Typically, I let the sauna warm up for about 20 minutes, then spend 30 to 40 minutes inside. By the time I’m done, I come out with a great sweat and feel refreshed and relaxed. Overall, I’m very happy with my purchase and feel like I’m already experiencing the benefits.

Hi Tilly! Thank you for taking the time to leave such a detailed and positive review. We are thrilled to hear that you are enjoying your new Rainier sauna and that the assembly process was easy with a second person's help. It's great to know that the sauna heats up quickly and the red light therapy feature is a valuable addition to your experience. We hope you continue to enjoy the benefits and relaxation of your sauna sessions. Thank you again for choosing our product!

Great Product & Customer Service

I love my one-person Ranier cedar infrared spa with the XL Red Light panel! It’s so much easier to use it first thing in the morning without worrying about running out of the house. A breeze to assemble and customer service was there to answer any questions. I would highly recommend this beautiful, convenient, intuitive spa and company.

Hi Tracy, thank you so much for your wonderful review! We’re delighted to hear that you’re loving your Rainier cedar sauna with the XL Red Light panel—it really does make it easy to start the day on the right note. We’re also glad the assembly went smoothly and that our team was able to be there for you when you had questions. Your recommendation means the world to us, and we wish you many more energizing mornings and relaxing sessions ahead!

As advertised!

I received my sauna two weeks ago fully intact with the exception of one heater bulb damaged in shipping, which Peak swiftly replaced. It was very easy to assemble.

I turn it on when I start my workout and it’s ready for a post workout session after about 30 minutes.

The red light panel is good quality but positioned well off to the side (as depicted in promotional materials however), making optimal exposure difficult. I will probably reposition or use as a standalone device.

Hopefully, it’s built to last!

Hi Kirk, thank you for sharing your experience! We're glad to hear your sauna arrived in good condition and is easy to use. We appreciate your feedback on the red light panel positioning and hope it works well for your needs. We're confident in the durability of our saunas and appreciate your trust. Enjoy your wellness journey!

This is a very nice unit and very easy to install; on the evenings that I use it, I sleep through the night without waking up

Thanks so much, Brennan! Glad to hear setup was easy and even better that you’re seeing those sleep benefits—that’s huge. Enjoy the sessions!

Love the Ranier sauna!

We have had the sauna for about a month now; I use it daily, and my husband uses it several times a week. We love it! It's labeled as a 1 person sauna, but technically 2 people could sit in there together (although a little snug). Shipping was incredibly fast, and it was super easy to put together. Bluetooth works well...my husband listens to podcasts via his phone, and I put my laptop on a cart outside the glass door and watch a show (makes the 30 minutes go by much faster, and keeps you from thinking about the buckets of sweat dripping down your back!) The cedar smells nice, it's not overpowering, and keeps the sauna smelling fresh. Our only complaint is that the Red light is positioned in such a way that you have to sit all the way to the side when it's on, and it still doesn't seem to reach the entire body; wish there was some sort of angle bracket to put in there so we could turn it a bit toward the center. (The 2 person sauna looks like there may be a little more room to the side of the red light, so it's probably not an issue in that one, but those require a dedicated plug, and we didn't have that). We are very happy with the Ranier sauna and highly recommend it!

Thank you so much for the thoughtful review—we love hearing how much you’re both enjoying the Rainier! Daily use is the best feedback we can get 🙌

Appreciate you calling out the setup, Bluetooth, and cedar as well. On the red light positioning, that’s great feedback—we’ll definitely pass that along to our product team as we continue to refine the design.

So glad it’s been a great fit overall—enjoy the sessions!

Better than I expected

wasnt sure if a 1 person sauna would feel cramped but the Rainier feels roomy and super comfortable. The wood smells amazing and the finish is really nice. The heat builds up quick and the smart controls make it easy to have it ready when I am. Worth every penny.

Thanks for sharing your experience with the Rainier. We’re so happy it exceeded your expectations and that you’re enjoying the smart controls and quick heat-up. Here’s to many relaxing and rejuvenating sessions.

Great Product but Delivery Could Be Faster

The sauna itself is amazing and works exactly as described. The XL red light panel feels like a pro setup at home. Only downside was delivery took a bit longer than I expected. Once it arrived though, everything was in perfect shape and setup was easy.

Thank you for your feedback. We’re glad to hear you’re loving the Rainier and that the XL red light panel is delivering the results you wanted. We appreciate your patience with delivery and will continue to work on making that process faster.

Perfect size and huge performance

I wanted something that wouldnt take up too much space but still had all the high end features. The Rainier nails it. The XL red light panel is incredible, I use it almost every day and can really feel the difference. Setup was way easier than I thought and the smart app makes it simple to heat up before I even walk in. Looks sharp in my home office and gets hotter than I expected for a 1 person model.

Thank you for your review. We’re so glad the Rainier is fitting perfectly into your space while still delivering the performance you wanted. That XL red light panel is a customer favorite and we’re happy you’re seeing results. Enjoy many relaxing sessions ahead.

Frequently Asked Questions

As soon as you place your order, you will receive an email from us with your confirmation details. Please keep this email for your records. After we receive your order we will begin preparing your order for shipment. 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.
