The Edge Tub Review 2022: Is The Edge Theory Labs Tub The Best Portable Cold Plunge?

Ready to take your Cold Water Immersion (CWI) game up a notch? The Edge Tub could be the perfect choice for you. It has revolutionized how people take a cold plunge and is quickly becoming a top choice for those looking for a customized CWI experience.

This review will take a closer look at what makes this The Edge Tub so special and discuss why it might be the perfect choice for your home (or your home away from home, too).

What is the Edge Tub?

The Edge Tub is a lightweight, portable cold plunge tub built with military-grade, drop-stitch inflatable technology. It’s also lightweight, weighing only 25 pounds. It has a standard 110 electrical connection, a backpack for transport, a Wi-Fi-enabled chiller, an air pump, and microfiltration. Plus, it only requires less than 15 minutes to set up.

Who Created the Edge Tub?

The Edge Tub was created by cousins Rob Church and Joshua Church. Rob and Joshua discovered the health benefits of cold water therapy while training for their first Ironman Triathlon. They constructed a cold tub and immersed themselves in it often during training, eventually becoming fascinated with the cold and motivated to spread the word about its great effects.

Rob’s experience in supply chain management and logistics and Joshua’s insights from a Wim Hof retreat in Iceland led them to develop The Edge Tub. They identified two issues: the high cost and the lack of mobility in cold immersion tubs. So, the Edge Theory team swooped in with a game-changing solution, and they did it for less than half the price of competing cold plunge tubs.

The tub is constructed from the same ultra-durable inflatable drop stitch material used by the Navy Seals and found in thousands of stand-up paddle boards around the country. The Edge Theory Labs’ mission is to create a human-friendly cold tub that can be assembled in minutes, transported easily, kept constantly cool without the need for ice, and is comfortable to sit in.

Best Features of The Edge Tub

Now, let’s talk about features. The Edge Tub has several features that make it stand out from the competition.

1. Portable and easy-to-set-up design

The Edge Tub by Edge Theory Labs is always ready, whether at home or on vacation. Its unique design means everyone can enjoy it – regardless of height or weight.

The company calls it “the world’s first all-in-one, portable cold tub,” – and they’re not wrong. It features a lightweight military-grade stitch inflatable technology that weighs only 25 pounds. Plus, it has a built-in air pump and a carrying bag, so you can take this tub with you when you’re on the go.

The Edge Tub has a standard 110V electrical connection, so you can assemble, use, and disassemble it quickly. Also, depending on the water pressure you have when filling, this may be set up or broken down in around 15 minutes. There are no tools or installation required. Just fill the tub with water, inflate it with air, hook up the hoses to the chiller, and put the power cable into any regular outlet.

Taking it down is just as easy as setting it up: remove all attachments, drain the water, and roll the tub back into its carrying case.

2. Wi-Fi Enabled Chiller

One of the best things about the Edge Tub is that you don’t need ice to keep it cold. It’s an iceless ice tub. It features a built-in chiller that can be controlled with a smartphone app. This means you can use it anytime, anywhere, even when no ice is available.

3. Hot and Cold Settings with Microfiltration System

The Edge Tub also has hot and cold settings, so you can use it for both hot and cold therapies. Within 2 hours, the Edge Tub can heat the water to 105 degrees or chill it to 37 degrees Fahrenheit. It also has a filtration system that ensures the water stays clean.

4. Fast Cooling/ Heating System

With its industrial-strength compressor, the Edge Tub can rapidly cool water to its desired temperature four times as quickly as conventional cold tubs. The time needed to reach the desired temperature will depend on the initial water temperature and the surrounding air temperature. To speed up the cooling process, add ice to the water while it is being poured into the tub.

What got you into cold water immersion?

I started doing ice baths about four years ago. My wife and I started learning about different ways the body can heal itself without using traditional medicines. I am in my late 40s and like to be as active as I can. Recovery from my workouts was taking longer than usual. We started looking at some of the foods that I was eating and realized that was a big part of it. Cutting out highly processed foods and sugary foods was the first thing.

Then we started to look at how to repair some of the damage I have done over the years. We found bone broth and came up with a great recipe that we really liked: super clean, no garlic, no additives, all organic, grass-fed grass-finished.

That turned into ice baths. I started with a 100-gallon stock tank and got ice from the restaurant where I worked at. That was fine for a while and I had some good results but was not something I could do forever and paying for ice every day was not an option.

Why did you purchase the Edge plunge?

When I saw the Edge Theory tub in a Facebook group I knew it was perfect. Living in the northeast part of the United States, we have great summers, springs, and fall, but the winters can get pretty chilly. I really like doing the ice bath outside in nature.

Having the ability to move it inside in the winter will eliminate the excuse of it being too cold out.

I have set it up and taken it down multiple times with no issues each time. The chiller is not light, but definitely something my wife can carry if she had to.

What temperature do you like to plunge at?

I have it set to 40°

How regularly do you use the plunge?

I do about three minutes every morning when I first wake up and then another 3 to 5 minutes after a workout during the day.

How long does it take to cool to your desired temperature?

My nine-year-old daughter loves that it can become a hot tub. Changing it from hot to cold or cold to hot is very easy and takes a couple of hours for it to go from 40° to around 95°.

How often do you need to change the water? Does it keep the water clean?

I’ve used it twice a day every day for the past 3 to 4 weeks and I have not changed the water once. I have had to change the filter one time and clean the strainer one time but other than that it has been very low maintenance.

What do you like about the Edge tub?

In addition to the benefits of circulation in the body and reducing inflammation, I love how dialled in I feel after some breathwork in the tub. It is a great reminder every day that you can overcome feelings of discomfort by focusing on your breath and doing a quick meditation. That’s really what I like about it. I feel like a gladiator when I get out of it. Ready to take on the day.

What are its flaws?

If I were to make one change to it, I would make it just a little bit bigger. I am 5 foot 11 and I can be fully submerged up to my neck with my knees bent in a comfortable position. To be fully submerged, I do need to get into an awkward position but it is not uncomfortable and I have gotten used to it so really not an issue.

The Edge Tub Price

For $4990, you can get The Edge Tub and enjoy all the benefits it has to offer. The company guarantees a full refund if you don’t feel like The Edge Tub has improved your recovery. They also have a 1-year replacement warranty. Instalment payments via Affirm and Klarna are also available for $174 and $208 a month, respectively.

Now that we’ve taken a detailed look at the Edge Tub, let’s compare it to some of the other options on the market.

Morozko Filtered Forge Ice Bath

The Morozko Filtered Forge Ice Bath is an excellent alternative to the Edge Tub. Its unique feature is that it can make its own ice. It also has a microfiltration system with ozone disinfection, a built-in controller, a cedar frame, and all-weather protection. However, it’s not portable and is a bit more expensive at $9,900.

The Cold Plunge

Another option is the Cold Plunge, a portable ice bath used indoors or outdoors. It can cool down to 39 degrees Fahrenheit and has a filtration system with ozone sanitation. The Plunge is suitable for both indoor and outdoor use. It’s simple to set up. You plug it in, fill the Plunge with water, switch it on, choose your desired temperature, and prepare yourself to get real cold.

Conclusion: Should You Buy The Edge Tub?

The Edge Tub is the perfect choice for those looking for a portable, easy-to-set-up tub for cold plunging. It’s also a great choice for those who want to boost their recovery time, improve circulation, and train their body to fight real stress.
