Sauna Health Benefits
Saunas offer a wide range of scientifically supported health benefits. Unlike traditional saunas, infrared heat penetrates deeper into the body, heating you from the inside out and promoting enhanced detoxification, circulation, and relaxation.
- Detoxification: Saunas increase sweat production, helping eliminate toxins like heavy metals and chemicals. Studies show that infrared therapy can boost detoxification by up to 20% more than traditional saunas.
- Improved Cardiovascular Health: Regular sauna use has been shown to lower blood pressure, improve circulation, and reduce the risk of heart disease by 46%, according to a study published in JAMA.
- Pain Relief & Muscle Recovery: Heat helps reduce inflammation, alleviate pain, and accelerate muscle recovery. Clinical trials report that 70% of patients with chronic pain experienced relief with consistent heat therapy.
- Skin Health & Anti-Aging: Saunas stimulate collagen production, improving skin elasticity and reducing wrinkles. Research shows an increase in skin hydration and a 26% reduction in wrinkles after regular use.
- Stress Relief & Better Sleep: Saunas promote relaxation by reducing cortisol levels, leading to better stress management and improved sleep quality. 83% of users report feeling more relaxed and sleeping better after sessions.
These benefits make saunas a powerful tool for overall wellness, helping you feel healthier inside and out.

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.
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.
The built-in red light therapy is in the ceiling of the sauna. If you're serious about getting maximum benefit from red light therapy, the additional panel is much more high powered and targeted than the built-in red light.
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.
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.
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.

I've only ever sauna-ed at spa spaces, never at home - which is a game changer. My neighbour recently got this - sweat before work, or after a workout (or karaoke) from your home is luxe! Plus the red light therapy is built in future focused! I'm hooked!

I purchased The Cardoba 2 Person Near Zero EMF Indoor Full Spectrum Infrared Sauna in early June. It arrived and was easy to assemble with just a little help for the weight of the sides. From the time I plugged it in I have been thrilled. It heats up quickly and when you step in it feels like you are stepping into Heaven!!! I love to set it at 135 and stay in for 25-30 minutes. It has eliminated all of my hip and lower back stiffness and pain. I can't say enough about the quality and worksmanship!!! It is just fabulous!!!

A Seamless Experience and a Game-Changer for My Routine
I just got my Peak Shasta sauna and I’m already in love! Delivery was smooth and seamless—it arrived right on time and in perfect condition, which was such a relief. The Peak team was amazing throughout the whole process, super responsive and helpful every step of the way. As a yogi and writer, I was hoping this would become a space to decompress and get inspired, and it absolutely is. I’ve already had a few brainstorm sessions inside and felt the ideas flowing. Plus, the red light therapy is no joke—my rosacea-prone skin is already looking calmer and less inflamed. So grateful I made the leap!

Obsessed!!! Best investment I've made in years...
Honestly, I couldn't be happier with my Peak Saunas Shasta! Delivery was super smooth and assembly was a total breeze — I actually put it together solo in about 45 minutes (totally doable, but definitely easier with two people). The design is super sleek and modern, and it's compact enough to fit in my bedroom without feeling cramped. That said, it's still roomy enough for me to kick my feet up and fully relax.
The heat-up time blew me away — it hit 140 degrees in just 10 minutes, and within 20 minutes it was up to 158 and I was SWEATING. The XL red light therapy panel is HUGE — way bigger than I expected in the best way. I’m turning 40 this year and got this mainly for muscle recovery and anti-aging perks—and honestly, it already feels like one of the smartest things I’ve done for myself.
Also, shoutout to the Peak Saunas team — they were so friendly, knowledgeable, and kept me in the loop every step of the way. Even though there was about a month delay (hey, it happens), it was so worth the wait. Hands down one of the best purchases I've made in a long time. If you're on the fence — just go for it!

Unbelievable Service
The test of a good company is how they perform during adversity. I ordered my Shasta 1-Person Full Spectrum Infrared Sauna with XL Medical-Grade Red Light Therapy & Smart WiFi App Control just before tariffs were imposed which resulted in long delay in shipments. This was beyond their control but they never abandoned me in answering inquires quickly and honestly. Once the unit arrived, the assembly and performance were as advertised. A small issue was resolved with the teams continued help. Their service was above and beyond. Thank you!

Great value and even better service
Just received my new Fugi two person sauna from Peak Saunas. It looks better in person and very easy to install. I looked at many other saunas but so glad I choose this one from Peak. Such a great sauna and unbelievable customer service. I had a few questions and every time they got back to me right away and were very polite. Can’t wait to use it. I owned a business for 40 years and that is how I treated my customers. Now it seems it is a surprise when you get good service but not with Peak

Finnmark Hybrid 2.0
Bought a Finnmark Designs hybrid 2.0 sauna.
Great sauna, very well designed and constructed. Went together easy and was up and running in less than an hour. While the sauna got hot enough, it did not reach 170 as advertised. Reached out to Finnmark directly and could get no response despite following their support process, even after several attempts over the course of 3 weeks. So I reached out to Peak. Rebecca from Peak customer support jumped right on the issue for me and directly facilitated interactions with technical support, even prompting technical support a couple times to get a status. I am sure without Rebecca I would never of received the attention from Finnmark I needed. The sauna issue was resolved after 5 weeks of interactions with the technician who finally sent a replacement heater panel. While the sauna is fine, I would be hesitant to get another Finnmark Designs sauna due to their poor customer service, excessive time spent convincing Finnmark that their sauna was not performing to the specifications. When the time comes to upgrade to a bigger sauna in the future, Peak is at the top of my list. I enjoy my sauna and use it almost daily, much appreciation to Rebecca and Peak for outstanding customer service !

If you are like me, you have been searching, researching and debating on the purchase of a sauna. Just do it! From the start I found the site easy to navigate and plenty of help to narrow down my search. The Peak team was there from the initial search through delivery and after to make sure everything is perfect with our new sauna. One helpful tip is that they are clear about what the electrical requirements are for your sauna and what type of plug you will need. The best sauna in the world will do you no good if you can't get it to turn on. That out of the way, next big issue was size. This was perfect for my wife and I to use together and for the space we wanted to put it. This fit perfectly on our covered back porch. Protected from the elements and we co go to the pool when we are finished. Delivery was simple. After ordering, I received a call on a Monday and it was delivered that Friday. One issue was I had to help the delivery driver move the pallet off the truck. Not Peak's fault, but that would have been an issue had I not been home for the delivery. It is a heavy pallet. It is perfectly packed to protect the contents. Breaking down the pallet and getting everything ready for construction was easy, just some heavy pieces. Only one required a little extra help from our kid, the front wall/door piece is a little heavier and needed an extra pair of hands to stabilize. Construction was simple, took longer just because we had some interruptions. Probably took 45-60 minutes in total. Started right up and began heating. We are in Florida, so starting temp was already 90. It got to 130 in under 10 minutes. I have used it six times in the first week. No problems at all. Syncing with my phone for some music is easy. Turn the red light on and sit back and relax. Stop reading this and go purchase yours now!

I made the right choice choosing Peak Saunas
I couldn’t be happier with my sauna purchase and the outstanding customer service that came with it. From start to finish, the entire team was fantastic—friendly, responsive, and truly invested in making sure everything went smoothly. A special shoutout to Danielle, who went above and beyond when I needed help with a warranty issue. Even though the heater problem was a manufacturer’s defect and not their fault at all, they handled everything quickly and professionally. It’s rare to find a company that stands by you after the sale, but this team absolutely delivered. Highly recommend!

My husband and I have been wanting a sauna for awhile. We did some research and went with a Finnmark that also has the red light therapy. The two of us put it together without any issues and it works great. We love it!
