THE MEDICAL SAUNAÂ STORY
Although there are many saunas out there, most are made by people who never went to medical school. After putting many of these saunas to the test, we realized that most saunas on the market did very little to help your health. Because saunas can have powerful medical benefits, we decided to become the very first company to work with doctors to truly unleash their full medical potential.
To create the ultimate medical sauna, we worked with many medical doctors, pain specialists, and cardiologists. We spent years researching health benefits of saunas, and added as many medical components as we could find. After 10 years of research and development, we were able to create a sauna with enough medical components that can help you relieve pain, improve cardiovascular health, strengthen your immune system, and detox your body. Because we focused solely on helping your body heal, we decided to call the finished line the Medical Sauna Seriesâ„¢.
MEDICAL BREAKTHROUGHÂ DISCOVERY
BREAKTHROUGHÂ FEATURES
DURABLE HEMLOCKÂ CONSTRUCTION
One problem that affects a lot of other saunas on the market is durability. When you first get your sauna, it may work fine, but after a few months of usage, it begins to lose heat. This is one of the most common problem that sauna owners face. Durability is a very important part of a perfect sauna because you want to be sure that your sauna can last well over 10 years of continuous use. What's the point of paying for a sauna that doesn't last at least 10 years?
After years of research, we decided to use natural hemlock for its medicinal and structural qualities. Hemlock hardens as it ages, meaning our saunas can actually get more durable the longer you own one. Hemlock is also known for its astringent properties, meaning it helps cleanse your skin, which enhances the already powerful detoxification benefits of Medical Saunasâ„¢. When you step into our hemlock saunas you will feel and smell the powerful natural wood aromas, leaving your skin feeling tightened and refreshed.
BASED ON DOCUMENTEDÂ RESEARCH
Â
Medical Saunasâ„¢ are based purely on documented studies. While many of our competitors make baseless claims without any proof, or worse, pseudo-scientific proof, we only list the medical benefits that have been found in documented studies. This is important to us because you deserve to have as much valid information as possible before you make a decision about your health. Because Medical Saunasâ„¢ are backed by documented research, you will really see how big of a positive impact regular heat therapy can have on your health.
We are extremely careful which products we put our name on. Because we make sure every product we create works for you, we only create products with an overwhelming body of documented research behind them. Improving your health is our top priority.
Â
ZEROÂ COMPROMISES
Medical Saunas™ are designed, developed, and hand assembled in the USA, and we ship them directly from our Los Angeles factory. We work with medical doctors, cardiologists, and pain specialists who have the same desire we do—to deliver great health to all of our customers.
We accept nothing less than perfection so we are in control of the product from start to finish; we don't allow any middlemen to compromise our vision. You can purchase our saunas directly from us with confidence, knowing that you're getting an unmatched product.
Rapid Internal Heating Systemâ„¢
An important feature that you should look for in a sauna is its heating capability. Most saunas, as shown on the left, only heat part of your body and can take nearly an hour just to heat up your sauna. This means you end up with less time actually spent inside the sauna, resulting in less healing and relaxation for you, not to mention increased energy bills, which means more money out of your pocket for less. That’s why we made the Medical Saunas™ with our Rapid Internal Heating System™. We are the first and only sauna to have it. The average sauna takes 90 minutes to 2 hours to pre-heat, but Medical Saunas™ can be fully heated in as little as 40 minutes. It outperforms the competitors and reaches the perfect temperature in a time that no other sauna can compete with. This powerful heating system allows you to be in your sauna immediately when you need it most.
Benefits of the Rapid Internal Heating Systemâ„¢
Another advantage to the creation of our Rapid Internal Heating Systemâ„¢ is that it can increase your endurance and strengthen your immune system. While other saunas may take 10 - 15 minutes to work up a sweat, when you step into our sauna, you will begin to sweat almost immediately. A rapidly heating sauna simulates the effect of working out because it increases your internal body temperature at a similar rate. Not only does this increase your heat tolerance, which leads to improved athletic performance, it also stimulates your immune system, which can make it better at fighting off infections and disease.
By using our sauna regularly, you will be actively improving your ability to withstand greater heat. This will give you a better performance in the gym, on the trail, or in the field. A common complaint among sauna users is that they want a quick recovery for their bodies by using a sauna, but many other saunas can’t provide this with their current heating systems. The Rapid Internal Heating System™ meets the needs of an average sauna user or an intense athlete. The system heats the Medical Sauna™ and your body up so fast that blood flows more quickly to your tired and strained muscles. This helps them recover faster and relax much quicker. Our perfectly engineered heating system will put your body at ease and you will feel completely renewed.
Hot/Cold Cleansing Systemâ„¢
Most heating systems in other saunas are too slow to heat up, making the benefits of warm up and cool down rounds that are recommended by so many sauna users and experts nearly impossible to achieve. Hot/Cold therapy has many health benefits, such as relaxing muscles and improving flexibility. The Medical Saunaâ„¢ has been designed to capitalize on this therapy method with our extremely powerful and efficient heating technology. The Rapid Internal Heating Systemâ„¢ is the most effective system that can achieve hot/cold therapy and allow you to reap the benefits and start improving your health.
The Detox Routineâ„¢
While most saunas say they can remove some toxins from your body, they miss some of the more dangerous ones to your health. Regular use of a Medical Saunaâ„¢ can remove bad toxins and impurities from your body. Many of these toxins are found in substances we use or are exposed to every day, such as BPA (found in many household plastic items), toxic heavy metals, phthalates (found in most fast foods), and nicotine. Medical Saunasâ„¢ are the industry leaders in removing toxins from your body. By following The Detox Routineâ„¢, regular use of a Medical Saunaâ„¢ will repeatedly enlarge the pores on your skin and flush out the harmful toxins inside your body, leaving you feeling energized and purified.
Insulated Airflow Systemâ„¢
For too long, sauna users have experienced unwanted temperature fluctuations in poorly designed saunas, resulting in less healing and higher energy bills. The insulation of a sauna is just as important as the heating system because it allows the temperature inside to remain constant. We have developed a design that works with our heating system, and uses the temperature inside the sauna to keep your sauna at a constant temperature. This means you can keep your sauna at the right temperature with less effort, and receive the maximum health benefits from our Medical Saunaâ„¢.
3D Heat Therapyâ„¢
Medical Saunaâ„¢ is the first and only sauna on the market to offer 3D Heat Therapyâ„¢. Heat therapy has many benefits for your body including improving sore muscles, increasing range of motion, decreasing muscle spasms, and reducing pain. The 3D Heat Therapyâ„¢ works by penetrating deep into the body's tissue and cells as temperature rises, which leads to therapeutic benefits all over your body. This improved version of heat therapy, found only in a Medical Saunaâ„¢, will rejuvenate your body from the inside out.
Safe Cool Down Systemâ„¢
No other sauna on the market has engineered an airflow system that creates a safer and more efficient cool down stage after using your sauna. An important health practice to follow when using a sauna is allowing your body to cool down gradually after a session. Medical Saunaâ„¢ has aided your cool down stage, as its design allows hot air to escape slowly from the sauna. This cools down your body at the recommended pace, and prevents possible health complications from changing temperatures too quickly. As a very vital process for a sauna owner, we felt it was necessary to design a cool down system in our saunas that will keep you safe.
Skin Rejuvenation/Cleansing Systemâ„¢
Only Medical Sauna’s™ heating technology can cover every square inch of your body and leave your skin feeling soft, fresh, and new. This is because of the Natural Canadian Hemlock wood used in the Medical Sauna Series™ and our powerful heating system. These two features remove dead skin cells from your body, allowing your pores to open wider, which results in increased blood circulation near the surface of your body, healing your skin. After just one session in a Medical Saunas™ your skin will feel younger and refreshed.
Medical Saunasâ„¢ are more than just relaxation tools because they were designed to help heal your body. Because of all the doctors that came together to help design and engineer the Medical Saunaâ„¢ and their 100+ years of combined experience, there are lots of medical benefits you can receive by using it daily.

This improved version of heat therapy, found only in a Medical Saunaâ„¢, will rejuvenate your body from the inside out.
Safe Cool Down Systemâ„¢
No other sauna on the market has engineered an airflow system that creates a safer and more efficient cool down stage after using your sauna. An important health practice to follow when using a sauna is allowing your body to cool down gradually after a session. Medical Saunaâ„¢ has aided your cool down stage, as its design allows hot air to escape slowly from the sauna. This cools down your body at the recommended pace, and prevents possible health complications from changing temperatures too quickly. As a very vital process for a sauna owner, we felt it was necessary to design a cool down system in our saunas that will keep you safe.
Skin Rejuvenation/Cleansing Systemâ„¢
Only Medical Sauna’s™ heating technology can cover every square inch of your body and leave your skin feeling soft, fresh, and new. This is because of the Natural Canadian Hemlock wood used in the Medical Sauna Series™ and our powerful heating system. These two features remove dead skin cells from your body, allowing your pores to open wider, which results in increased blood circulation near the surface of your body, healing your skin. After just one session in a Medical Saunas™ your skin will feel younger and refreshed.
Medical Saunasâ„¢ are more than just relaxation tools because they were designed to help heal your body. Because of all the doctors that came together to help design and engineer the Medical Saunaâ„¢ and their 100+ years of combined experience, there are lots of medical benefits you can receive by using it daily.

THE MEDICAL SAUNAÂ STORY
Although there are many saunas out there, most are made by people who never went to medical school. After putting many of these saunas to the test, we realized that most saunas on the market did very little to help your health. Because saunas can have powerful medical benefits, we decided to become the very first company to work with doctors to truly unleash their full medical potential.
To create the ultimate medical sauna, we worked with many medical doctors, pain specialists, and cardiologists. We spent years researching health benefits of saunas, and added as many medical components as we could find. After 10 years of research and development, we were able to create a sauna with enough medical components that can help you relieve pain, improve cardiovascular health, strengthen your immune system, and detox your body. Because we focused solely on helping your body heal, we decided to call the finished line the Medical Sauna Seriesâ„¢.
MEDICAL BREAKTHROUGHÂ DISCOVERY
When the full potential of a sauna is reached, saunas can provide a lot of medical benefits from pain relief to body detoxification and improved cardiovascular health to reduced stress. That's why we spent so much time working with doctors, pain specialists, and cardiologists to creat the ultimate line of saunas. We developed our award-winning combination of therapies with each feature specifically chosen for the medical benefit it can give you.
BREAKTHROUGHÂ FEATURES
DURABLE HEMLOCKÂ CONSTRUCTION
One problem that affects a lot of other saunas on the market is durability. When you first get your sauna, it may work fine, but after a few months of usage, it begins to lose heat. This is one of the most common problem that sauna owners face. Durability is a very important part of a perfect sauna because you want to be sure that your sauna can last well over 10 years of continuous use. What's the point of paying for a sauna that doesn't last at least 10 years?
After years of research, we decided to use natural hemlock for its medicinal and structural qualities. Hemlock hardens as it ages, meaning our saunas can actually get more durable the longer you own one. Hemlock is also known for its astringent properties, meaning it helps cleanse your skin, which enhances the already powerful detoxification benefits of Medical Saunasâ„¢. When you step into our hemlock saunas you will feel and smell the powerful natural wood aromas, leaving your skin feeling tightened and refreshed.
BASED ON DOCUMENTEDÂ RESEARCH
Medical Saunasâ„¢ are based purely on documented studies. While many of our competitors make baseless claims without any proof, or worse, pseudo-scientific proof, we only list the medical benefits that have been found in documented studies. This is important to us because you deserve to have as much valid information as possible before you make a decision about your health. Because Medical Saunasâ„¢ are backed by documented research, you will really see how big of a positive impact regular heat therapy can have on your health.
We are extremely careful which products we put our name on. Because we make sure every product we create works for you, we only create products with an overwhelming body of documented research behind them. Improving your health is our top priority.
ZEROÂ COMPROMISES
Medical Saunas™ are designed, developed, and hand assembled in the USA, and we ship them directly from our Los Angeles factory. We work with medical doctors, cardiologists, and pain specialists who have the same desire we do—to deliver great health to all of our customers.
We accept nothing less than perfection so we are in control of the product from start to finish; we don't allow any middlemen to compromise our vision. You can purchase our saunas directly from us with confidence, knowing that you're getting an unmatched product.
Rapid Internal Heating Systemâ„¢
An important feature that you should look for in a sauna is its heating capability. Most saunas, as shown on the left, only heat part of your body and can take nearly an hour just to heat up your sauna. This means you end up with less time actually spent inside the sauna, resulting in less healing and relaxation for you, not to mention increased energy bills, which means more money out of your pocket for less. That’s why we made the Medical Saunas™ with our Rapid Internal Heating System™. We are the first and only sauna to have it. The average sauna takes 90 minutes to 2 hours to pre-heat, but Medical Saunas™ can be fully heated in as little as 40 minutes. It outperforms the competitors and reaches the perfect temperature in a time that no other sauna can compete with. This powerful heating system allows you to be in your sauna immediately when you need it most.
Benefits of the Rapid Internal Heating Systemâ„¢
Another advantage to the creation of our Rapid Internal Heating Systemâ„¢ is that it can increase your endurance and strengthen your immune system. While other saunas may take 10 - 15 minutes to work up a sweat, when you step into our sauna, you will begin to sweat almost immediately. A rapidly heating sauna simulates the effect of working out because it increases your internal body temperature at a similar rate. Not only does this increase your heat tolerance, which leads to improved athletic performance, it also stimulates your immune system, which can make it better at fighting off infections and disease.
By using our sauna regularly, you will be actively improving your ability to withstand greater heat. This will give you a better performance in the gym, on the trail, or in the field. A common complaint among sauna users is that they want a quick recovery for their bodies by using a sauna, but many other saunas can’t provide this with their current heating systems. The Rapid Internal Heating System™ meets the needs of an average sauna user or an intense athlete. The system heats the Medical Sauna™ and your body up so fast that blood flows more quickly to your tired and strained muscles. This helps them recover faster and relax much quicker. Our perfectly engineered heating system will put your body at ease and you will feel completely renewed.
Hot/Cold Cleansing Systemâ„¢
Most heating systems in other saunas are too slow to heat up, making the benefits of warm up and cool down rounds that are recommended by so many sauna users and experts nearly impossible to achieve. Hot/Cold therapy has many health benefits, such as relaxing muscles and improving flexibility. The Medical Saunaâ„¢ has been designed to capitalize on this therapy method with our extremely powerful and efficient heating technology. The Rapid Internal Heating Systemâ„¢ is the most effective system that can achieve hot/cold therapy and allow you to reap the benefits and start improving your health.
The Detox Routineâ„¢
While most saunas say they can remove some toxins from your body, they miss some of the more dangerous ones to your health. Regular use of a Medical Saunaâ„¢ can remove bad toxins and impurities from your body. Many of these toxins are found in substances we use or are exposed to every day, such as BPA (found in many household plastic items), toxic heavy metals, phthalates (found in most fast foods), and nicotine. Medical Saunasâ„¢ are the industry leaders in removing toxins from your body. By following The Detox Routineâ„¢, regular use of a Medical Saunaâ„¢ will repeatedly enlarge the pores on your skin and flush out the harmful toxins inside your body, leaving you feeling energized and purified.
Insulated Airflow Systemâ„¢
For too long, sauna users have experienced unwanted temperature fluctuations in poorly designed saunas, resulting in less healing and higher energy bills. The insulation of a sauna is just as important as the heating system because it allows the temperature inside to remain constant. We have developed a design that works with our heating system, and uses the temperature inside the sauna to keep your sauna at a constant temperature. This means you can keep your sauna at the right temperature with less effort, and receive the maximum health benefits from our Medical Saunaâ„¢.
3D Heat Therapyâ„¢
Medical Saunaâ„¢ is the first and only sauna on the market to offer 3D Heat Therapyâ„¢. Heat therapy has many benefits for your body including improving sore muscles, increasing range of motion, decreasing muscle spasms, and reducing pain. The 3D Heat Therapyâ„¢ works by penetrating deep into the body's tissue and cells as temperature rises, which leads to therapeutic benefits all over your body. This improved version of heat therapy, found only in a Medical Saunaâ„¢, will rejuvenate your body from the inside out.

Full spectrum or far infrared: which do I need?
A full spectrum sauna gives you near, mid and far infrared in one cabin; a far infrared sauna uses far infrared only and usually costs less for the same size. If you want the widest range of heat settings, choose full spectrum. If budget comes first, compare far infrared models in our low EMF infrared saunas. Our full spectrum vs far infrared guide covers the differences in depth.
What is a hybrid full spectrum sauna?
A hybrid sauna pairs full spectrum infrared heaters with a traditional sauna stove in the same cabin. The Golden Designs GDI833001 uses a Harvia 6 kW stove and the GDI836001 a Harvia 8 kW stove, and the GDI833001 lists an infrared temperature range of 118 to 132°F. The stove side needs its own electrical circuit; the GDI836001, for example, lists a 240V / 40 amp service. For stove-only cabins, see our traditional saunas.
What should I check before ordering?
- Floor space and ceiling height against the dimensions on the product page.
- The electrical service listed for the model, especially for hybrids with a stove.
- Indoor or outdoor use: many full spectrum cabins, such as the DYN600903, are listed for indoor use only. For a backyard, choose from our outdoor saunas.
- EMF level, if it matters to you: titles and specs list near zero, zero or under 3 milligauss for many models.
