Our Story - Frozen, the world's first Medical Cold Plunge.

We noticed a problem: most cold plunges were designed by people without medical degrees. We believed there was a better approach. With Medical Saunas' team of 48 doctors and engineers, we collaborated to develop the ultimate medical cold plunge – one that would optimize and unlock the true medical potential of cold water therapy.

When we started Frozen™, our engineers aimed to do more than just develop another plunge. We wanted to make the best plunge for our friends and family, ensuring it would be safe for them to use. We dove headfirst into researching every cold plunge in existence. We read every negative review, scrutinized every comment, and examined all the issues to ensure our friends, family, and customers wouldn't encounter the same problems.

With a substantial investment from Medical Sauna, we began by buying and testing over 53 different cold plunges in the US. And we didn't stop there. Our relentless pursuit of perfection and our goal to develop the world's best medical cold plunge motivated us to seek more investment to buy and import over 112 cold plunges from all over the world, filling our testing facility to the brim. Due to the varying electrical requirements across the globe, we had to construct different electrical stations to test each country's plunge.

"We acquired so many plunges to test that we barely had room to walk around."
~Lewis Bonfield
Engineer @ Medical Saunas

After extensive studying, testing, and analyzing numerous forums, we compiled a list of features for the perfect cold plunge. We prioritized practical additions, such as a timer to track how long you've been in the plunge without relying on a phone, which could fall into the water. We also sought numerous comforts that we needed every time we used the plunge, including water and weather-resistant spaces for robes, towels, phones, and watches. We aimed to add as many features as possible while staying true to our mission of optimizing its medical benefits.

Frozen™ didn't achieve success overnight.

Although cold plunges have gained popularity in recent years, we refused to settle for just any design. It took 2.5 years of 14-hour days, six days a week, and more than 23 prototypes before we engineered a model that received the unanimous approval of all 48 medical professionals on our team.

We hope you love Frozen™ as much as we do.


All of our cold plunges come with a limited 3-year warranty included FREE.

Frozen Energy Shock™ -We engineered Frozen™ using water that is so close to freezing that it gives you the Frozen™ Shock of Energy - a burst of energy when you enter the near-freezing water. You'll love it and become addicted to Frozen's Energy Shock because it's going to wake you up.

Healthy & Safe 37° Freezing™ - Because Frozen™ is developed by doctors, health is of utmost importance to us. To keep you healthy and safe, the lowest temperature Frozen™ will reach is 37 degrees Fahrenheit. This is close to freezing and is considered the lowest safe temperature for any cold plunge, making Frozen™ one of the safest plunges to use regularly.

FoamSeal™ Military-Grade Insulation - While many cold plunges merely insulate the tubes and the back of the plunge, we take it a step further by insulating everywhere, including the outer and inner tank with military-grade insulation. This approach reduces the cooling time of Frozen's water by 2X, making it cool faster than that of many of our competitors.

20 Ultra Micron Filter System™ - The Frozen 20 Ultra Micron Filter System not only removes hair, skin cells, and debris but also captures particles as small as dust particles that are constantly flowing into the water. Unlike our competitors' micron filter systems that leave small dust particles in the water, our ultra micron filter system is so fine that it constantly removes any small particles that flow into the water, keeping your water ultra-clean.

Military-Grade Exterior with UV Protection - Frozen's shell is military-grade, just like the Cybertruck. It's ultra-tough and features a UV protective coating to protect it from the damages of the sun.

Indoor & Outdoor - We want you to enjoy the benefits of Frozen™ as much as possible, so it is designed to be used indoors or outdoors and can withstand all weather elements, including rain, sun, or snow. You can place it anywhere you want.

No Plumbing Needed, Just Plug & Play - No plumbing or drain is needed, and with proper care, Frozen's water can last up to 6 months. Frozen™ comes with everything you need. Just buy one and experience the natural, raw energy as you plunge into Frozen.

Cleaning and Maintenance

Change the Water Regularly
The frequency of changing the water in your cold plunge depends on the level of usage. Generally, it is recommended to change the water every week or two, depending on the amount of use. Empty the old water and scrub the interior of the cold plunge with a mild cleaning solution. Rinse thoroughly and refill with fresh water. This will help to remove any build-up of bacteria and contaminants.

Monitor Chemical Levels
Chemicals such as chlorine or bromine are necessary to kill bacteria and maintain the cleanliness of the water. However, it's essential to monitor the chemical levels regularly to ensure they remain within safe ranges. Use a test kit to check the levels of pH, alkalinity, and sanitizer, and adjust as needed. You can find chemical kits on amazon.

Skim the Surface
Regular skimming of the surface of the water is an essential part of keeping your cold plunge clean. Use a skimmer net to remove leaves, insects, and other debris from the surface of the water. This will prevent them from sinking to the bottom and becoming a breeding ground for bacteria.

Keep the Surrounding Area Clean
The area surrounding your cold plunge can also affect its cleanliness. Keep the area swept and free of debris and discourage users from bringing in dirt or grass clippings on their feet. This will help to reduce the amount of dirt and debris that enters the cold plunge.

The Medical Benefits of Cold Plunge Therapy Explained

Improve Circulation
Frozen is an effective way to promote healthier circulation and overall well-being. When you take a dip in a cold plunge tub, your body is subjected to a rapid change in temperature that causes the blood vessels to constrict, pushing the blood towards the vital organs and increasing the heart rate.

This shock response floods the body with oxygen and nutrients, reviving and replenishing the organs with energy. The improved blood flow is then sustained throughout the day, contributing to a healthier circulatory system. With regular cold plunge sessions, you can expect to experience profound long-term benefits.

Reduce inflammation
Cold plunges reduce inflammation in the body causing constricting the blood vessels. This reduces the flow of blood to any area that is experiencing pain or discomfort, like a sports injury, which helps to decrease swelling and inflammation. Frozen is a great way to naturally help your body heal and stay healthy!

Boost immune Function
Taking a plunge into cold water can be an incredible boost to your health. It activates the white blood cells that are responsible for fighting off sickness, and it also causes the lymphatic system to contract—pushing fluids through the lymph nodes. This process helps detoxify your body and strengthen your immune system. Studies have shown that cold plunges can reduce upper respiratory tract infections significantly.

Specific Health Benefits of Cold Plunges 

Reduce inflammation
Studies have shown that cold water immersion can be highly effective at reducing the effects of Delayed Onset Muscle Soreness (DOMS) after intense physical activity. This is the sore and painful feeling in your muscles after you have done intense exercise.

This effect is likely due to its natural pain-relieving properties. Cold plunging is a great way for athletes and fitness fanatics alike to give their bodies the relief they need after an intense workout session.

Increase Alertness and Energy
A cold plunge bath can provide a quick pick-me-up and can help you be more energized, while regular use can deliver long-term effects. When you take a cold plunge bath, you’ll experience immediate increases in alertness and energy, improved mood, reduced inflammation and soreness.

In the long run, regular cold plunging can help you get focused, and decrease stress and anxiety.

Improve Skin and Hair Health
Taking a cold plunge in a cold tub can provide numerous benefits for skin and hair health. Cold water helps to close your pores, protecting against dirt and bacteria from entering the skin, reducing inflammation and redness, and boosting circulation which leaves your skin with a radiant glow.

Not only does the cold water help with the skin, but it can also leave your hair looking shinier and healthier too. If you’re searching for more reasons to turn down the heat in the shower, this is a great one – softer skin and vibrant looks await!

What are Cold Plunges Good For?

Post-Workout Recovery
By taking a cold plunge tub within two hours of finishing your workout, you can experience a number of important benefits. When done correctly, cold plunges can help flush away lactic acid build-up, reduce inflammation, and promote better circulation throughout the body.

These effects can lead to quicker recovery times. Additionally, because cold plunges are known to stimulate endorphin production in your brain, they can also help to improve your mood after a challenging workout.

Stress Relief
Cold plunging is a great way to reduce stress. By exposing yourself to the controlled shock of cold water on a regular basis, your body gradually gets used to it and develops a resilience towards it. This adaptation also extends to other sources of stress, as cold plunging helps reduce cortisol levels – the hormone that is released when you’re under stress. Repeated cold water plunging can help your body develop a stronger reaction to and better handle all kinds of stress.

Improved sleep
Cold plunging can help to improve sleep quality by increasing the production of melatonin, a hormone that helps to regulate sleep-wake cycles.

Increased metabolism
Cold plunging may also help to increase metabolism, which can lead to weight loss.

Improved athletic performance
Cold plunging can help to improve athletic performance by increasing muscle strength and endurance.

Reduced risk of heart disease
Cold plunging may also help to reduce the risk of heart disease by increasing the production of nitric oxide, a molecule that helps to relax blood vessels and improve blood flow.

Medical Benefits of Frozen Cold Plunge

From Dr. Aaron Cypess, a clinical researcher, to neuroscientist Andrew Huberman and orthopedic surgeon Dr. David Geier, the medical community is raving about the medical benefits of the cold plunge. Many recommend that their patients add it to their daily routine. Over 48 doctors, physical therapists, chiropractors, nurse practitioners, pain specialists, physical therapy aides, and surgeons have contributed to the development of Frozen™. As a result, it stands as the world's first cold plunge designed to help medically enhance metabolism, improve blood flow, promote muscle healing, boost circulation, reduce inflammation and stress, and provide comprehensive pain relief, ultimately leading to improved sleep quality. temp

 Frequently Asked Questions

1. Do I need to add ice to Frozen?
No, you do not need to add ice. Frozen will cool down naturally and stay cold, allowing you to use it whenever you wish. Simply set it to your desired temperature, and it will maintain that level, ready for use at any time. Initially, it might take some time to reach the right temperature, similar to a hot tub. So, if you've just set up your cold plunge and want to use it immediately, you can add ice to hasten the cooling process. But after the initial cooling, it will remain cold and ready for you to use, just like a chiller.

2. So, you put water in and Frozen will freeze it, right?
Yes, but not entirely. The cold plunge won't freeze the water completely into a block of ice, as that would make it unusable. Rather, it will cool the water to a temperature near freezing, allowing you to use it. You can adjust it to any temperature you're comfortable with, but it's capable of getting extremely cold, close to the freezing point, if you prefer it that cold.

3. How much electricity does Frozen use?
Frozen is energy-efficient. In fact, it is so energy-efficient that it uses the same amount of electricity as many beverage chillers.

4. What are the electrical requirements of Frozen?
It operates on a 120-volt system and will work with any standard household plug. Similar to a computer or other appliances, you simply plug it in, and it will work.

5. Can I adjust temperature and make Frozen warmer? 
Yes, you can adjust the temperature from 37 degrees all the way to room temperature. According to, the average room temperature in most homes is between 68 and 72°F, so you can adjust your cold plunge from freezing cold to a comfortable 72°F.

6. Is Frozen Cold Plunge self-cleaning? 
Yes, it has both a UV sanitizing system and an advance self cleaning filtration system that keeps Frozen's water completely clean.

7. Is there any bulky equipment outside of Frozen? 
Many popular cold plunges have bulky equipment outside of them, creating a tripping hazard. However, their advertisements often fail to show these potentially unattractive elements because they don't display angles that include the bulky equipment in their ads. In contrast, Frozen is elegantly designed with all equipment neatly contained inside. This arrangement prevents any equipment from protruding and becoming a trip hazard, making Frozen one of the safest plunges to use.
