Frozen 1™ Cold Plunge Features

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 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.

The Medical Frozen 1™ Cold Plunge

The Medical Benefits of ColdPlunge 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 

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!

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.

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.

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.

Frequently Asked Questions

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 mini fridge.

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.

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.
