Medical Sauna is a company that’s fairly new to the industry. But their saunas are quickly selling out as they continue to produce models that are equipped with all the bells and whistles buyers could ever want in a medical grade infrared sauna that’s designed for home use. This is currently the only sauna on the market that has been designed by a team of medical professionals. This model was developed over a period of several years and includes all the features you’ll need for a total body detox, natural pain relief, or a relaxing session after work. Bottom line, if you’re looking for a sauna that can deliver all the IR therapy benefits you’ve read about, your search is over.

Our Verdict: The 4 Full Spectrum sauna by Medical Sauna is large enough to seat up to two users for a traditional sauna experience, or one user if you’re interested in a hot yoga workout. The interior control panel allows you to precisely adjust the temperature, control the built-in speakers, set the timer, or control the light therapy settings. Made from beautiful hemlock and featuring a solid construction, it’s clear that this is a sauna that was designed to last.

Overview and Features

Right off the bat, when you visit the manufacturer’s website you’ll notice that they boast that this sauna is currently the only model on the market that has been designed by doctors. The sauna itself is designed to increase muscle recovery speed, treat migraines and cluster headaches, improve blood flow, and reduce stress, promote sleep, and relieve pain.

Since this company is fairly new, their claim that this sauna has been designed by licensed physicians puts them on equal footing with longstanding companies in the industry. But does this model really have what it takes to compete with the big boys? Let’s find out.

Doctor Designed

Not only is this sauna well-built, but it was designed by the pros. Obviously, one of the biggest selling points is the fact that this sauna was designed by a team of medical professionals. Despite the fact that there are literally dozens of top-selling infrared saunas on the market these days, it’s true that this is the only one that has been designed by healthcare professionals. Since saunas are said to have impressive medical benefits, it makes sense that input from professionals would result in one of the most effective and powerful home infrared saunas on the market.

The company worked closely with a team of doctors, cardiologists, and pain specialists to come up with this design. But it didn’t happen overnight. In fact, it took several years of researching infrared technology and all the benefits associated with ongoing treatment to learn more about the full effects of infrared sauna use. In total, it took ten years of tests, studies, and development to come up with a sauna that could truly deliver all the benefits most companies claim their saunas can. The design resulted in a sauna that’s said to be able to effectively treat pain, improve cardiovascular health, boost the immune system, and promote detoxification.


As you can see, spending just twenty minutes a day in your sauna can come with a wide range of health benefits including weight loss, stress reduction, improved blood circulation, and a natural way to treat and prevent migraines. It can also help you unwind after a long day at the office, remove tension from the body, and soothe tired, aching muscles.

Heat Therapy in 3D

The type of heaters a sauna uses is one of the most important specs to pay attention to. This model is equipped with a total of seven full spectrum heaters. These heaters have been strategically placed in all the essential areas that can provide the user with the full benefits of sauna use. The 3D heat therapy design will allow you to experience the full benefits of heat therapy, all around you. Lower priced saunas may only have a panel located directly in front of you, but the manufacturer clearly knew what it was doing by providing full coverage treatment, which equals more effective results.

The sauna’s rapid internal heating system is designed to strengthen the immune system and increase endurance. Since this sauna can heat up almost instantly, you’ll notice that you will begin to sweat as soon as you step over the threshold. The sauna uses an omnidirectional heating design so the heat will be dispersed at all angles.

Hot and Cold Cleansing System

The sauna’s hot and cold cleansing system is one of this model’s best features. Users will be able to feel the real benefits of switching between hold and cold. Not only will you enjoy the full effects of IR therapy, but the cold feature is actually ideal for safety since new users can easily become overheated their first few times in a sauna, especially if they don’t keep track of how long they’ve been in it. This sauna utilizes temperature regulation in order to prevent overheating, dehydration, headaches, and other symptoms that are associated with overuse. Doctors often recommend taking a ten to fifteen minute cooling period for every fifteen to twenty minutes you’re in a sauna and once your session is completed, so this is a great feature to have.

Detoxification Process

The main reason many people purchase a sauna is for its ability to naturally promote total body detoxification. When you use your sauna, each time, as you sweat, toxins, impurities, and metals are flushed from the body. But not only are these harmful toxins removed you’ll also enjoy clean pores and clearer looking skin.

Airflow System

The sauna’s insulated airflow system consists of tempered glass combined with a wood design that works well to insulate the sauna for more effective treatment.

Cabin Design

The sauna is made out of natural hemlock, which is considered the best option, as well as the purest one for sauna use. Hemlock is also completely free of allergens and any harmful chemicals.

Easy Assembly

It’s obvious that the manufacturer has thought of everything. If you don’t want to waste more than an hour assembling your new sauna, then you’ll love this model’s easy clasp design. This design will allow you to assemble the sauna in under an hour and break it down within twenty minutes. This will allow you to easily move the sauna from room to room if needed.

Built-in Speakers

The built-in speaker system complete with Aux, USB and Bluetooth connectivity will allow you to pair the speaker system with a wireless device so you can listen to your favorite toons as you sweat.

Hot Yoga Anyone?

This sauna is also the first hot yoga sauna on the market. If you’re not familiar with hot yoga, it’s said to be a form of yoga that helps you lose weight faster and detox your body as you stretch and sweat your way to a thinner, more flexible body, and it’s done in hotter temperatures. Fortunately, this sauna’s cabin is pretty large, so it’s perfect for yoga lovers who want to detoxify their skin, lose water weight, and burn calories, without having to go to a local yoga studio.

Control Panel

The Simple Touch control panel is located on the inside of the sauna. The intuitive controls will allow you to switch the sauna on and off, set the temperature, and a timer for each session.

Light Therapy

Light therapy can help to promote relaxation after a long day at the office or a tough workout session. You can also adjust the light therapy settings using the control panel inside the cabin.

What is the Humidity Like in this Sauna?

An infrared sauna is not like a traditional sauna in the sense that a high level of humidity in the air will cause you to sweat. Instead, the infrared heating system will heat the skin, not the air. Because of this, there is no need for a humid environment. To learn more about how infrared saunas work, click here to read our buyer’s guide.

How this Model Measures Up

Many buyers are interested in the latest feature many leading brands are incorporating in their infrared sauna design, which is the addition of a negative ion generator. This feature is commonly found on higher priced models. Unfortunately, this model lacks this important feature.  If you’re interested in a sauna that does come with an air ionizer, then we recommend the Durasage Infrared IR Far Ion Portable Indoor Personal Spa Sauna hotwhich comes loaded with some great features and is available at a comparable price. However, aside from the negative ion generator, the Durasage doesn’t quite measure up to the performance this sauna has to offer. It’s a portable sauna, which means it’s very limited in terms of durability and comparable features. If you’re looking for a sauna that’s designed to last and comes loaded with some great extra features, then stick with the Medical Sauna.
