Inergize Cold Plunge Review

If you’re new to the idea of cold plunging, it’s exactly what it sounds like — plunging into frigid water (sub-50 degrees) to take advantage of potential benefits, like speeding up muscle recovery and boosting immunity. While most dedicated cold plunges dominate a lot of space and aren’t portable, the Inergize Cold Plunge dodges these issues with its inflatable design, which allows it to be packed down and stored in a duffle bag when deflated. Including the inflation process and filling the tub with water, this plunge only takes around 20 minutes to set up, and the chiller on the side offers temperatures ranging from 37 to 107 degrees — meaning it can also serve as a hot tub. 

The price tag is around $5,000, which is significantly more expensive than a plunge that doesn’t feature water temperature regulation, but you won’t have to buy multiple bags of ice every time you want to plunge. Plus, the filtration system sanitizes your water, preventing you from constantly draining it after your plunge sessions. If you’re searching for a high-quality cold plunge that works well in tight spaces, the Inergize Cold Plunge may be the one for you. Now, let’s dig into why this is one of our favorite cold plunges on the market.

Inergize Cold Plunge Highlights

• Price: $4,990
• Temperature Control: The included chiller will keep your water as cold as 37 degrees and as hot as 107 degrees
• Materials: The same drop-stitch polyester fabric used for inflatable paddle boards
• Dimensions: (Outside) 51” L x 28” W x 30” H — (Inside) 43” L x 20” W x 30” H

While a $5,000 price tag may be steep for some people, the luxury of not having to purchase ice or drain your water after one or two uses is often what sells people on plunges like this. This is still a product best suited for dedicated cold plungers, so if you’re a beginner or not sold on the potential benefits, you might be better off with a cheaper alternative. 

The 1,800-watt chiller on the side of the tub is about as straightforward as it gets. Just plug it into your standard 120v outlet, select your desired temperature, and it’ll take care of the rest for you. While we haven’t tested this out yet, it’s worth mentioning that the chiller also offers water as hot as 107 degrees. So, if you want your plunge to double as a hot tub, this may be your best bet since other companies charge about $500 more for hot water. Also, you can download the Tuya Smart app to control the chiller from your phone.

Since this is, in fact, an inflatable cold plunge, it’s understandable why someone would initially be concerned about durability — especially when some acrylic tubs cost the same price. However, we don’t think you should worry about any tears since the drop-stitch polyester fabric feels as tough as a two-dollar steak. Granted, we wouldn’t use it near barbed wire, but it’s durable enough to withstand the outdoor elements and strong enough to rest your arms on it to support your body when plunging. 

The overall footprint is similar to acrylic and fiberglass cold plunges, but the ability to deflate it and stash it in the included duffle bag could be the perfect solution for anyone tight on space. And since the inside is 3.5 feet long, most people can fully submerge their body during their plunging sessions.

Pros

• The option to deflate this plunge and put it into storage is clutch for those tight on space, and you can easily take it on a trip with you.
• The chiller on the side of the tub will regulate your water temperature anywhere from 37 to 107 degrees.
• The filtration system will remove impurities from your water, drastically reducing the frequency of draining the tub.

Cons

• You will have to check the air pressure every couple of days if you intend on this being a stationary plunge. 
• With a $5,000 price tag, this tub may be too expensive for some people.
• While this tub seems pretty durable, it’s still not as durable as an acrylic or fiberglass plunge.

Using the Inergize Cold Plunge

When testing it out, one of our favorite things about the Inergize Cold Plunge was the ease of use and how fast it was to set up. We timed ourselves, and it only took 20 minutes to inflate the tub and cover, connect the hoses from the chiller to the tub, and fill it with water. So this tub almost acts like a true plug-and-plunge cold plunge. You’ll just have to wait for the water to drop (or rise) to your desired temperature — you can expect it to take about four hours to go from 65 to 37 degrees.

The chiller itself is really easy to use; just use the arrows to select the temperature, and you’re all set. While we didn’t use the WiFi feature, we think the option to control it from your phone could be the selling point for those who want to get the chiller started remotely so it’s ready when they get home from work. The drop-stitch polyester build is durable enough to be placed outside and strong enough to support your body as you get in and out of it. The filtration system also adds to the luxurious nature of this plunge and reduces the frequency in which you need to drain your water, but the coolest thing about the Inergize plunge is that you can deflate it, stash it in the duffle bag, and take it anywhere you want. 

Installation

The 20-minute installation process for this cold plunge is about as straightforward as it gets, plus their guided videos are extremely helpful. Just bust out the included bike pump, fill the tub and cover with air, connect the hoses, plug in the chiller, toss in your hose to fill it up, and you’re all set. 

The pump has a pressure gauge on the top, which is handy cause you’re not supposed to fill it with more than 10 PSI of air, or else you could pop it. Their website claims it will only release one or two PSI per month, but we had to add more air after a few days because it had already deflated a bit. 

Temperature Settings

The ability to control the water temperature is one of the best things about luxury cold plunges like this, with temps ranging from 37 to 107 degrees. Not only do you skip out on purchasing anywhere from 70 to 100 pounds of ice during the dog days of summer, but you can also utilize hot water here for some relaxation time.

Filtration System and Water Sanitation

Another major selling point of the Inergize Cold Plunge is the filtration system. The micron filter removes impurities from the water, so you don’t have to drain it as frequently. You’ll also receive a four-month water maintenance kit with your purchase to properly sanitize it.

It’s recommended you test the water with the included testing strips once a week, and based on what the strips read, either add the oxidizer or sanitizer (or both) to ensure you aren’t plunging in harsh water.

Materials

Some people may be skeptical about the durability of an inflatable cold plunge, but the drop-stitch polyester build is built for the long haul. While we don’t recommend sitting on top of it with the cover attached, it’s still strong enough to support your body as you get in and out.

Dimensions

Even though this plunge is smaller than competitor cold plunges like The Plunge Cold Plunge, it still requires a decent amount of space. For reference, the exterior of the actual plunge measures a little over four feet long, just over two feet wide, and 2.5 feet tall. 

Plus, you need to account for the chiller, which measures one foot long and one foot wide. So, if these dimensions don’t work for you, you might want to consider a smaller option — a barrel-shaped one like the Ice Barrel or the Redwood Outdoors Alaskan Cold Plunge might be a better option. 

Regarding the interior dimensions, you’re working with 43 inches in length, 20 inches in width, and 30 inches in depth. This is still pretty spacious, and even those around six feet four inches tall can likely fully submerge their body by bending their knees before dunking their head.

What to Consider Before Buying The Inergize Cold Plunge

This is no doubt an investment, so there are a few crucial factors to consider before you bite the bullet and purchase this cold plunge. We always want people to consider the price tag, but you also need to consider the size and whether or not you want a plunge with a chiller.

Price

Cold plunges are not cheap, and this one will run you around $5,000. While we think the chiller, portability, and the option of deflating it whenever you want makes it worth the money — that’s still a chunk of change. If you want a dedicated cold plunge but want to save a couple thousand dollars, you could always target a model that doesn’t feature a chiller. 

That said, you’ll find yourself being pretty wasteful since you must purchase loads of ice and constantly drain your water. And if you have oodles of available space at home and don’t want to deal with adding air every few days, you can find an acrylic or fiberglass model like The Plunge or the Polar Monkeys Brain Pod for about the same price. 

Temperature Control

While some folks don’t mind tossing in bags of ice for their plunge sessions, this can get pretty pricey since the outdoor temperature pretty much determines the amount you have to buy. For example, for one single session, we had to purchase 100 pounds of ice when plunging in a barrel-shaped plunge one day during the summer. That will certainly add up over time, so if you want to avoid that hassle, a plunge with a chiller is the way to go. 

While the low setting of 37 degrees is pretty standard across the market, most companies will make you pay an extra $500 or so for hot water. Since that’s not the case with the Inergize tub, we think you’re getting a bit of a steal. 

Dimensions

Similar to adding a power rack to a home gym, you need to map out your available space before adding this cold plunge to your personal space. Now, it’s still smaller than some other options, and you can always deflate it, but it will still require a dedicated space. So, long story short, just be sure you can make it fit at home before spending your hard-earned money.

Portability

For those who find themselves traveling a lot, this is our pick for the best portable cold plunge on the market. It’s really easy to deflate, fold, and stash it in the included duffle bag. Plus, it only weighs 25 pounds, so it’s pretty easy to lug around. 

Keep in mind that you still have to lug around the 60-pound chiller with you. Fortunately, it has a set of wheels to slide it around, and Inergize recommends you keep the wooden box it comes in during transit to protect it while traveling.

Inergize Cold Plunge Vs. Competitor Cold Plunges

It’s always a good idea to compare products like a barbell or some dumbbells to other options on the market to decide which one is best for you, so why not do the same thing with a cold plunge? Below is a table comparing the Inergize Plunge to various options. 

	Inergize Cold Plunge Tub	The Plunge	Redwood Outdoors Alaskan Cold Plunge Tub	Ice Barrel 400
Price	$4,990	$5,000	$2,000	$1,200
Temperature Control	Chiller	Chiller	Ice (optional chiller upgrade)	Ice
Dimensions	51” L x 28” W x 30” H	67” L x 43” W x 24” H	40.5” H x 37” W	42” H x 31” W
Materials	Drop-stitch Polyester	Acrylic	Scandinavian Thermowood	Plastic

We chose these specific plunges because not everyone wants the same things. If money is ultimately your biggest concern, then the Ice Barrel 400 is undoubtedly the way to go; just remember you’ll have to spend a decent amount of money in the long run on bags of ice. The same goes for the Alaskan Cold Plunge Tub unless you spend an extra $2,500 on the chiller. We included this one because the thermowood is beefier than the plastic build of the Ice Barrel, and it’s better insulated. 

If you want a cold plunge that allows you to lie down and stay in one specific spot, then The Plunge might be the way to go. It’s essentially the same price as the Inergize tub, and the acrylic build is the most durable. However, one thing the Inergize tub has that none of the others do is the portability. Plus, it offers hot water without paying extra money, like you’ll have to do with The Plunge and the Alaskan Cold Plunge Tub.

This is hands down our favorite portable plunge on the market and is ideal for those who travel a lot or for anyone who wants to tuck their plunge out of sight from time to time. Just remember, if you do decide to travel with it, you’ll still have to lug around the chiller. You can’t go wrong with any of these plunges, but the right one may differ from person to person. So do your homework and align your budget with your needs, and you’ll land on the right product. 

Warranties

Inergize offers a six-month commercial and one-year residential warranty covering any manufacturing defects with the tub and chiller. However, this does not cover normal wear and tear or negligent usage.

You can purchase your cold plunge tub directly through the Inergize website.

Final Word

There are many potential benefits to hopping into an icy plunge, but not everyone has the proper space that most require, and they can be a pain to move around. But that’s not the case with the Inergize Cold Plunge. While you still need a dedicated space for it at home, you can easily deflate it, stash it in the included duffle bag and store it in a closet, or toss it in the back of the car as you’re headed out for a road trip. 

The drop-stitch polyester build is durable enough to handle being outside, the chiller offers temperatures ranging from 37 to 107 degrees, and the filtration system will remove impurities from your water. While it still costs around $5,000, we think this is the best bet for anyone looking for a portable cold plunge, and it stacks up well against the rest of the competition regarding stationary plunges.
