Medical Sauna noticed a problem: most cold plunges were designed by people without medical degrees. They believed there was a better approach. With Medical Saunas' team of 48 doctors and engineers, they collaborated to develop the ultimate medical cold plunge one that would optimize and unlock the true medical potential of cold water therapy.
After extensive studying, testing, and analyzing numerous forums, Medical Sauna compiled a list of features for the perfect cold plunge. They 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. They also sought numerous comforts that they needed every time they used the plunge, including water and weather-resistant spaces for robes, towels, phones, and watches. They aimed to add as many features as possible while staying true to our mission of optimizing its medical benefits.
FEATURES
Frozen Energy Shock
Feel instantly energized with our revolutionary near-freezing hydrotherapy. The Frozen Energy Shock uses precision-calibrated cold water to send an awakening jolt through your body. Once you try this exhilarating frozen water experience, you’ll be hooked on the instant alertness it provides.
Healthy & Safe 37° Freezing
Our cold plunge technology is doctor-developed to energize you while remaining within safe temperature ranges. Frozen’s waters only reach a minimum of 37 degrees Fahrenheit – the lowest recommended temperature for regular cold water immersion.This makes Frozen one of the safest cold plunges for regular use.
FoamSeal Military-Grade Insulation
While many cold plunges just insulate the tubes and back of the unit, Frozen goes a step further by insulating everywhere, including the outer and inner tank with military-grade insulation. This approach reduces Frozen’s cooling time by 2X, allowing it to cool faster than many competitor models.
20 Ultra Micron Filter System™
The Frozen 20 Ultra Micron Filter System doesn’t just remove hair, skin cells, and debris, but also captures particles as small as dust that are constantly entering the water. Unlike competitors’ micron filters that leave tiny dust particles behind, Frozen’s ultra micron system is so fine it constantly removes any small particles flowing into the water, providing a superior clean.
Military-Grade Exterior UV Protection
Frozen’s shell is military-grade, similar to the Cybertruck. It’s ultra-tough and has a UV protective coating to shield it from sun damage.
Indoor & Outdoor
Frozen is designed for versatility so you can enjoy the benefits as much as possible. It can be used indoors or outdoors and withstands all weather elements like rain, sun, or snow. You can put it wherever you want.
No Plumbing Needed, Just Plug & Play
Frozen requires no plumbing or drain. With proper maintenance, the water can last up to 6 months. It’s an all-in-one system, including everything you need to start experiencing the invigorating thrill of cold water immersion. Just purchase Frozen and take the plunge into its refreshing chilled water.

FAQ
-
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.
-
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.
-
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.
-
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.
-
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.
-
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 Sciencenotes.org, the average room temperature in most homes is between 68 and 72F, so you can adjust your cold plunge from freezing cold to a comfortable 72F.
-
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.
