Out of all the best muscle recovery tools at your disposal, a cold plunge tub offers unique benefits that can help you feel refreshed and rejuvenated for your next workout. While this frigid form of hydrotherapy isn’t for the faint of heart, it can be a useful way to reduce inflammation, support your immune system, and manage stress.
Our team of certified personal trainers, competitive athletes, and CrossFit coaches tested more than 20 of the best cold plunge tubs and researched dozens more to see which would deliver the best cold plunge experience.
We also consulted with Dr. Mike Masi, a doctor of physical therapy (DPT), to assess the merit of this recovery method and examine each tub using our fitness equipment testing methodology. After that, we had the content medically reviewed by Dr. Bilal Ahsan, a resident physician in Physical Medicine and Rehabilitation (PM&R) who specializes in musculoskeletal, neurological, and sports-related conditions. Dr. Ahsan helped ensure accuracy throughout the article.
To narrow down our list, we used a 1-5 scoring system to rate key factors such as:
- Footprint and Portability: How much space does the tub take up? Is it easy to move when not filled with water?
- Durability and Construction: Does it feel stable when getting in and out of the water? Does the material retain temperature well?
- Draining and Cleaning: How easy is it to dump the water and ensure cleanliness?
- Conveniences: Is there a way to monitor or regulate the temperature? Are there added features, such as a phone holder or lights? These can help enhance your cold plunge experience.
Whether it’s massage guns, saunas, or another tool, we’ve helped more than 650,000 athletes connect with high-quality recovery equipment. Let’s dive into our picks so you can choose the right cold plunge tub based on your needs, budget, and space.

Best Cold Plunge Tub Overall: The Plunge
Updated by: Stephen Sheehan, CPT, CNC
Plunge is a user-friendly cold-immersion therapy tool that’s easy to clean and maintain. The $5,000 price tag may just be too much for many people.
What our tester says:
“The biggest benefit is that you don’t have to go to the store and get a lot of bags of ice and fill up a tub. Honestly, if you plan on taking consistent ice baths, this is by far the ideal option, even though it’s costly up front.”
Best Luxury Cold Plunge: Sun Home Cold Plunge Pro
Updated by: Stephen Sheehan, CPT, CNC
The Sun Home Cold Plunge Pro is a sleek, high-end cold plunge option that can be used indoors or outdoors. It has a powerful chiller that can cool water down to 32 degrees in a matter of minutes. While it has a modern look with the chiller integrated into the design, the price point is about $15,000.
What our tester says:
“There was literal ice everywhere in the tub and hot damn that water is cold! It’s also incredibly sturdy, this will never lose its shape.”
Best Budget Cold Plunge: Polar Dive PRO
Updated by: Matt Dustin, CSCS, PN1-NC
This upright cold plunge is available with or without a chiller, allowing users to customize the plunge to their needs and budget. It’s easy to set up, and large enough to fit a wide variety of body types.
What our tester says:
“It’s under $1,000, it has an ultra-quiet chiller, easy setup… I really have no major callouts to this cold tub.”
Best Outdoor Cold Plunge: Redwood Outdoors Alaskan Cold Plunge Tub
Updated by: Caine Wilkes, OLY, CNC, USAW-L1
Redwood Outdoors Alaskan Cold Plunge Tub offers a vertical option for folks who’d rather sit upright versus lay down and pretend to relax while submerged in cold water. The Scandinavian spruce wood exterior gives The Alaskan a classic spa look and feel for your cold plunge sessions. It’s worth noting the base price does not include a chiller but it can be added for an additional cost.
What our tester says:
“It has a built-in seat, which many vertical plunges don’t have. I also love how easy this is to set up and use. It is heavy at 250 pounds, so it’s not portable.”
Best Cold Plunge Tub For the Money: Plunge Air
Updated by: Caine Wilkes, OLY, CNC, USAW-L1
The Plunge Air is part of Plunge’s new Evolve series and it aims to make cold plunging more accessible. This plunge is inflatable and portable, and compatible with a chiller.
What our tester says:
“The seams are strong, it doesn’t require re-inflating a few times a week, and the hoses are also better quality. Our assembly and testing teams both think this is the most durable inflatable tub we have.”
Best Vertical Cold Plunge: Nordic Wave Viking Gen 2
Updated by: Stephen Sheehan, CPT, CNC
The Viking Gen 2 Cold Plunge from Nordic Wave is a vertical cold tub option that allows you to sit in an upright position. It also comes with a chiller and filtration system. The biggest updates from the original is that the chiller now heats and you can choose between the 0.8-horsepower standard chiller and a 1-horsepower Elite chiller. The 2-inch-thick insulated walls allow for temperatures as low as 35 degrees Fahrenheit or as high as 104 degrees.
What our tester says:
“This vertical cold plunge is compact, durable, can heat and chill, and comes in at a comparable price to other cold plunge tubs. I like the upgraded version of the Nordic Wave Viking.”
Best Inflatable Cold Plunge: Sun Home Cold Plunge
Updated by: Caine Wilkes, OLY, CNC, USAW-L1
The Sun Home Cold Plunge was described by our expert product testers as “the most durable inflatable tub” they’ve seen. It can be used with hot or cold water and sets up easily.
What our tester says:
“We have had multiple people in and out of the tub, kept water in it for over two weeks, and have had no issues with the tub keepings it shape. When I compare the outer shell of this inflatable tub to others we have received, I’d place money on this one lasting the longest.”
Best Hot and Cold Plunge: Polar Monkeys Brainpod 2.0
Updated by: Stephen Sheehan, CPT, CNC
The Polar Monkeys Brainpod 2.0 is a fairly small cold plunge tub option. While the website doesn’t indicate how many gallons of water it takes to fill the tank, the website does provide the weight with and without water, so we estimate it has a 55-gallon capacity.
What our tester says:
“I like the angle of the tub, which makes it very comfortable to lean into and relax. Also, there isn’t any sort of wobble or give to the tub, and it felt solid when it was on the ground.”
Best Smart Cold Plunge: Plunge All-In
Updated by: Jay Serafino
The Plunge All‑In delivers a premium, app-connected plunge experience with fast cooling to 37 degrees Fahrenheit and optional heating, perfect for dedicated home recovery setups. The downsides? It’s expensive and has a large footprint.
Best Portable Cold Plunge: Cold Life Plunge
Updated by: Stephen Sheehan, CPT, CNC
The Cold Life Plunge is a sleek vertical tub that immerses the user in waters as cold as 37 degrees Fahrenheit and is super simple to set up and use, according to our expert product testers.
What our tester says:
“I think people who are larger and taller will be really comfortable using this tub. You can’t fully extend your legs, but it does feel really spacious and big. You need to sit upright and will be in more of a crunched up position, but I like that. Some people might want more of a horizontal position.”
Best Indoor Cold Plunge: Hydragun Supertub Cold Plunge
Updated by: Stephen Sheehan, CPT, CNC
The Hydragun Supertub Cold Plunge comes with 0.8-horsepower chiller, which can be excellent for a range of climates. This inflatable cold tub is constructed of military-grade vinyl material and holds its shape well.
What our tester says:
“You can put your body weight on the edge when getting in and out, which is not always possible with inflatable tubs. It has held up to our wear and tear, holds its shape, and supports your weight.”
Best Customizable Cold Plunge: Inergize Cold And Hot Plunge Tub
Updated by: Stephen Sheehan, CPT, CNC
The Inergize Cold and Hot Plunge Tub allows you to regulate the water temperature with the touch of your phone. You can prepare the water for hot or cold therapy modalities depending on your needs. The inflatable tank is portable and comes with a duffle bag for packing up and bringing with you. The tank has a 60- to 70-gallon water capacity and you can choose your temperature between 37 to 105 degrees.
What our tester says:
“Several of us have tested this tub, and it has held up like a champion. I had to bend my knees in order to fit, but I felt as comfortable as one can during my experience.”
Best Cold Plunge Tub for Small Spaces: Nordik Recovery Ice Bath
Updated by: Stephen Sheehan, CPT, CNC
The Nordik Recovery Ice Bath is an inflatable plunge tub that can be used with ice or a standard or premium chiller. Either way, it can be ready to use in under 10 minutes.
Best DIY Cold Plunge: Tuff Stuff Super-Duty Oval Stock Tank
Updated by: Stephen Sheehan, CPT, CNC
While a utility stock tank is most often used for gardening or farming, we see no problem using it as a cold plunge tub. The tank has a 110-gallon capacity, it’s made from sturdy low-density polyethylene (which is UV, heat, cold, and crack resistant), and it has a plug for easy draining. It might not offer temperature regulation or a ton of insulation, but it could be a great cold therapy hack for budget-conscious folks.
What our tester says:
“As long as you don’t mind using your own ice, this is a great cold tub. It’s great for places like small, gritty gyms where multiple people want to take ice baths, but you aren’t making a ton of money, or you aren’t able to fit a bougie tub.”

Other Cold Plunge Tubs We Researched
While we’ve tested nearly every tub featured on this list, we’ve researched a dozen more. Here are some other brands that didn’t quite make the cut:
- Blue Cube Bath: The main reason we didn’t test or recommend this brand is because there are no tubs priced under $10,000, which doesn’t make it affordable for the average home gym owner.
- Polar Monkeys Portal 2.0: This cold plunge tank didn’t make the list because it’s not insulated and is meant for outdoor use only. We have more details about the Portal 2.0 and Star Treatment 2.0 cold plunge tubs in our Polar Monkeys Cold Plunge Review.
How We Picked and Tested The Best Cold Plunge Tub
For any equipment our product testers use or research, we have a strict testing methodology in place so each of our experts has the same considerations when working through trials. Here are the factors we had in mind when testing cold plunges, specifically:
- Footprint and volume: We not only considered how much space this is going to take up (in your home, garage, porch, or backyard) we also wanted to know how much water each cold plunge tub holds relative to the footprint.
- Delivery and setup: While researching and testing, our experts noted if it was an easy setup process (like just unboxing or inflating) or if it was difficult and required full assembly.
- Durability and construction: When something is designed to hold water, we expect it not only to do just that but resist rust, mold, and general wear and tear.
- Ergonomics: Although seated or reclined is a personal preference, we wanted to be sure there is wiggle room and a design that allows you to put your arms out of the tub, if desired.
- Additional conveniences: These are things that go beyond just providing a place to hold cold water like chillers, filtration, or temperature regulation apps.
- Price and value: While cold plunge tubs are often expensive additions to your home gym, we wanted to consider what you’re getting for the price (which often includes chillers, pumps, and filtrations systems).
Benefits of a Cold Plunge Tub
If you’re wondering why some folks invest thousands of dollars to chill out at home, there are many science-backed benefits of cold plunging. From reduced inflammation to improved immunity to stress management, let’s dive into how this recovery method can enhance your overall well-being.
Potential to Reduce Inflammation
For most folks, muscle soreness after a workout is inevitable. But for athletes, being sore can hinder performance, especially if an athlete has back-to-back events (like a doubleheader baseball game or a multi-day bike race).
Dr. Michael Masi, doctor of physical therapy (DPT) and strength coach, notes that ice baths make the most sense for athletes.
“Cold water immersion can help with muscle recovery because it reduces the inflammation from working out and provides less perceived soreness,” says Dr. Mike. “In reality, inflammation is a natural response to aid muscle growth.”

In other words, full-body cold water immersion can help reduce perceived soreness but it doesn’t necessarily help with muscle recovery or muscle growth1.

Immune System Benefits
While more research on immersion therapy and the immune system is still needed, at the moment, there is research to support2 that the combination of cold exposure, breathing exercises, and meditation can activate the sympathetic nervous system. Doing this provides an epinephrine release (which is basically adrenaline) that can help regulate your natural immune response to fight infections.
Dr. Raj Dasgupta, MD, FACP, FCCP, FAASM, says, “Cold water exposure can increase the production of white blood cells in the body, which are responsible for fighting infection.”
The key here is not cold water exposure, alone—it’s the combination of breathwork and meditation that activates the sympathetic nervous system and provides immunity benefits. This method is typically referred to as the Wim Hof Method.

Boosts Metabolism
Studies have shown that going into a cold plunge before or after a workout may increase metabolism. “In addition to the production of body heat by normal basal metabolic processes, the body is, in addition to physical exercise, able to generate extra heat through the process of shivering and nonshivering thermogenesis,” a September 2022 study in the International Journal of Circumpolar Health says3.
Mental Health and Stress Management
Mental health is another area that still has many unknowns about the potential benefits of ice baths. However, related to the activation of the sympathetic nervous system, this activation can also be helpful to the way you feel and your overall perception. One study4 found that participants of a four-week trial found a reduction in stress, anxiety, and depression after regular cold water exposure every week for four weeks.
RELATED: Exercise and Mental Health
“There are several reasons to think that ice baths might provide mental health benefits,” says Dr. Raj Dasgupta, MD, FACP, FCCP, FAASM. “Immersing yourself in icy water triggers the release of stress hormones. This is likely why people say that a dip in cold water wakes them up. Some believe that an ice-water face immersion can activate the parasympathetic nervous system, which prompts the body to relax after a stressful event. Some researchers also hypothesize that adapting to the shock of ice water plunge may improve a person’s ability to cope with other stresses.”
Improved Circulation
Cold plunges are often used to improve circulation, which may also contribute to a cold plunge’s ability to reduce inflammation and support immune health.
“The working hypothesis is that the ice water stresses and strains your body, and it goes into survival mode, working hard to maintain its core body temperature,” according to Dr. Raj Dasgupta, MD, FACP, FCCP, FAASM. “This stimulates your body to increase blood flow and improve circulation in order to help deliver oxygen and nutrients to areas of the body that need to recover.”
GGR expert contributor Christopher Mohr, PhD, RD, echoes that sentiment, noting that ice baths may reduce muscle soreness and inflammation after intense exercise.
“Exposing your body to the cold can stimulate the vagus nerve, leading to decreased heart rate, relaxation and may help manage anxiety. All of this might can help improve stress levels and sleep quality over time,” he explains.
Buying Guide: What to Look for in the Best Cold Plunge Tubs
Here are some things to consider before you order a cold plunge tub for your home gym:
Size and Capacity
Like any large piece of equipment, measure your space! You’ll also need to consider how you’ll fill up the tank and how close your proposed area is to a water source. If the tub you’re considering has a chiller, you’ll also need a power source nearby, too.
It’s also worth noting that cold plunge tubs come in various sizes and capacities. If you’re adding a cold tub to your deck, be sure that the total weight of the tub (when full with water) can be supported. Some of the tanks featured on this review are several hundred pounds when full.

Insulation and Material
The material of the tub is crucial for maintaining the desired water temperature. Look for tubs made from high-quality, durable materials that offer good insulation. High-quality insulation will help retain the cold water temperature and minimize heat exchange with the surrounding environment. Stainless steel or high-grade acrylic are popular choices for cold plunge tubs due to their durability and insulation properties.

RELATED: How to Insulate A Garage Gym
Filtration and Maintenance
Proper water filtration and maintenance are essential to keep the water clean and safe for regular use. Look for a cold plunge tub that comes with a reliable filtration system. Additionally, consider the ease of maintenance and cleaning. A well-designed tub with easy-to-access filters and simple cleaning procedures will save you time and effort in the long run.

Warranty Policy
Compared to other large and costly purchases you’ll make for your home gym, the warranty policies on most cold plunge tubs pale in comparison to big investments like the best squat racks and treadmills. Most of the tubs we included offer a one-year warranty, while only a few have a five-year policy. While this may not be a dealbreaker, we think it’s worth thinking about.
Power Supply Requirements
Many cold plunges that use a chiller require access to a 120V power supply in your home. This is the standard outlet voltage in most North American homes and shouldn’t be an issue, but it’s something to keep in mind. If you’re buying a tub with a chiller, make sure there’s a nearby outlet where you’ll be setting it up.
Portability
While some cold tubs are very light and portable, some are very large and heavy, and aren’t meant to be moved on a regular basis once installed. If you plan on moving anytime soon, or you need a tub that can be moved from room to room between uses, you’ll want to choose a lighter, smaller cold plunge.
Ice vs. Chiller Trade-Offs
One of the first decisions to make is whether you’re looking for an ice tub or a cold plunge that’s powered by a chiller, both of which have their pros and cons. An ice tub is significantly cheaper, but you’ll need access to large quantities of ice on a regular basis, which can be inconvenient. Tubs with chillers can be pretty expensive, but they eliminate the need for ice and offer more precise temperature regulation.
Indoor vs. Outdoor Use
While just about any tub or cold plunge can be used indoors, if you’re going to have yours outside, uncovered, you’ll want to make sure it’s outdoor-safe. Outdoor tubs will be exposed to the elements, so you’ll likely need a tub with a cover and waterproof construction. It’s worth taking the time to make sure your tub is suitable for outdoor usage before making a purchasing decision.
Noise Level
Piggybacking off the indoor vs. outdoor consideration, you’ll also want to find out how loud your tub of choice is before making a purchase. While a louder cold plunge tub isn’t as big of a deal outdoors, the noise won’t have anywhere to go if you’re using it in a tight indoor environment.

The National Institute for Occupational Safety and Health5 recommends that you not be exposed to sounds at or above 85 decibels throughout an 8-hour workday to help prevent noise-induced hearing loss. While cold plunge tubs won’t typically reach those levels, GGR Everything lead reviewer Lindsay Scheele said she has run across models that measured 77 decibels, which is comparable to the noise level of landscaping equipment running outside when you’re indoors, according to the Hearing Health Foundation6. It’s not dangerously loud, but you’ll probably have to raise your voice to hold a conversation around it.
Noise from a cold plunge tub typically comes from the chiller, with Lindsay noting that 1-horsepower models tend to be the loudest. Before making your purchase, figure out where your tub will be located and look into the chiller specs to see what type of noise level you can expect.
Temperature Control and Range
The best cold plunge tubs on the market will typically get as low as 37 degrees Fahrenheit, but some may dip to 32 degrees. More important is the fact that some models can double as hot tubs that climb to 105 degrees or higher. If you’re the type who loves to soak in both extremes (and have the budget necessary to indulge), you might want to opt for one of these combo models.
Then, there’s the little issue of how you actually set these temperatures. Some tubs are just barrels that you fill with ice and water. Other builds can feature either built-in or add-on chillers that make the water ice-cold with the push of a few buttons. If you love that level of convenience, go with the chiller. You can even take it a step further and find a tub model that you can control through an app on your phone, allowing you to schedule plunges with exact temperatures in advance throughout the week.
Remember, though, if you’re using your cold plunge regularly, the cost of buying all of that ice is going to add up. While a chiller is a bigger upfront investment, it might be the smarter move down the road.
Budget
This may seem obvious, but your budget plays a significant role in deciding which cold plunge to buy. They can range from under $100 to nearly $15,000, so you’ve got a lot of choices. At the low end, you’re looking at inflatable tubs meant to be filled with ice, while the more expensive options include features like water filtration, heat settings, remote control via a phone, and more.
Common Mistakes to Avoid When Buying a Cold Plunge Tub
Cold plunge tubs are a serious investment, with certain high-end models costing $10,000 or more. With that sort of green on the line, you’ll want to make sure you dot your i’s and cross your t’s during the purchasing process. Here are some common mistakes you’ll want to avoid:
Buying a Tub That’s Too Small (or Too Tall)
This one should be obvious, but how many times have you made a purchase online only to realize—uh-oh!—it’s the wrong size? While most horizontal cold plunge tubs should be roomy enough to fit most people, you definitely need to do your research if you’re on the taller side (think 6 feet, 5 inches and up). Getting a tub that’s too small can severely hamper your ability to plunge properly, turning a promising recovery tool into a cramped fiasco.
Conversely, vertical tubs can be a chore to get into if you’re not tall enough. While you can get a step stool to help you climb in and out, you might not love the idea of traveling down plastic steps while soaking wet.
Before making your purchase, pore over the specs and read as many reviews (including ours!) as possible to get a feel for the tub’s size. Remember, it needs to be comfortable enough to plunge in and easy enough to get in and out of while wet.
RELATED: Cold Plunge Vs Hot Tub
Ignoring Cleaning and Maintenance
Many of the tubs on this list earned our seal of approval due to their sturdy construction, but even the most durable models won’t last if you don’t take care of them. If you ignore the recommended cleaning schedule and put off necessary maintenance, like filter replacements, your tub won’t work as well as it could. Plus, proper cleaning and water sanitization help cut down on any mold and bacterial growth that can creep up over time.
These steps are even more important if you have an outdoor tub. You need to avoid as much exposure to the elements as possible, so you’ll want to buy an insulated tarp (if it’s not already included) to drape over your tub during the colder months, and be sure to change the water temperature to accommodate the outdoor conditions.

Chillers that run both hot and cold are especially convenient for warming the water slightly during the frigid months to help prevent pipes from freezing and other ice damage. In the past, our testers have set their water temperature to around 40 degrees Fahrenheit during the winter without any problems. Before making a purchase, reach out to the brand’s customer service to ask about model-specific maintenance tips for cold weather.
If you aren’t going to use your tub outdoors during the winter, make sure it’s fully drained and dry to prevent ice damage. If possible, move it indoors to reduce any risks.

Going Too Basic
It’s all well and good if you just want a simple barrel to fill with ice and water, but you have to make sure that this is all you want out of a tub. Some of these simple barrels don’t have the ability to add a chiller, turn into a hot tub, or be controlled through an app. If you’re going to spend money on a plain barrel, just make sure you’re 100% certain you won’t get the itch for more bells and whistles in the near future.
Cold Plunge Safety Tips
While cold plunges can be excellent recovery tools, safety is critical, especially when submerging your body in near-freezing water. Here are some essential safety tips to keep in mind when using a cold plunge.
Keep in mind, this is not medical advice, and you should always consult with a physician before using a cold plunge, especially if you have any pre-existing health conditions.
Cool Down Before You Plunge
A cold plunge can seem like a refreshing way to cool off after a challenging workout. Still, experts recommend allowing your body to cool off first to avoid extreme temperature fluctuations naturally.
“Ice baths can potentially cause cardiovascular strain from the sudden temperature change,” says Chris Mohr, PhD, RD. “People with heart diseases, high blood pressure, and pregnant women should avoid ice baths or consult with a healthcare provider first.”
Cover Your Plunge
We recommend keeping your plunge covered when not in use. Not only will this help keep your water free of debris, but it can also ensure nobody accidentally falls in, especially if you have small children in your house. The frigid water can be quite a shock to your body, and kids may not be prepared for the extreme temperature fluctuations.
Limit Your Time
Chris Mohr, PhD, RD, recommends limiting your time to 10 to 15 minutes per session to avoid health issues like hypothermia. He also suggests that beginners start with moderate temperatures before moving to the coldest settings, saying, “For those new to plunging, you should first fill your bathtub with cold water and, if that’s not cold enough, add ice to it until it reaches a temperature of about 50 to 59 degrees Fahrenheit.”
Types of Cold Plunge Tubs
A cold plunge is a cold plunge is a cold plunge, right? Well, if you’ve read this far, you probably understand that these tubs are a bit more complicated than they appear. Here are the main types of cold plunge tubs and who they can be best suited for:
Inflatable Cold Plunge Tubs
Just like you’d imagine, these cold plunge tubs aren’t made of hard plastic, stainless steel, or wood. Instead, they’re typically made from durable ripstop materials and filled with air, offering a budget-friendly, portable silhouette that can be taken on the go.

Despite the travel-friendly motif, there are some trade-offs here. Obviously, you need to spend time inflating and deflating the tub when you want to use it. (Don’t worry, many brands include a hand pump.) Additionally, despite how sturdy most of these models are, you’ll usually be very aware that you are in an inflatable tub whenever you move around. Still, many of these tubs have comparable features with their sturdier counterparts, including compatible chillers, the ability to turn into hot tubs, and smartphone controls.
Vertical Barrels
Some people would rather sit upright than kick back in a cold tub. If you’re in that camp, you might fare well with a vertical plunge design. Not only do these tubs tend to work well for taller folks, but the vertical setup helps to cut down on their overall footprint, making them a great choice for a garage gym or patio plunge setup.
These barrels can be made from wood or plastic, and you can also find a lot of barebones models on the market without chillers or smart features. This can help keep the price in check, as long as you’re fine with providing the water and ice.
DIY Cold Plunge Tubs
This is a broad term for any cold plunge tub that you rig up yourself. The easiest way to craft a DIY cold plunge is to buy a stock tank—the kind cows and horses drink from on a farm—from your closest Tractor Supply or Home Depot and fill it with water and ice. It might not seem glamorous, but it gets the job done and could be a great introductory peek into the plunge life.
Premium Tubs With Chillers
If plunging is a foundational part of your fitness routine, it might be worthwhile to invest in a premium model decked out with a compatible chiller unit. These tubs are the ultimate in convenience, with many allowing you to switch between hot and cold temperatures and schedule plunges remotely through an app. The best examples of these tubs also have built-in filters and sanitation features, making maintenance and cleaning even easier.

What these tubs offer in convenience, they more than make up for in price, with many ringing up at $8,000 or more. Still, plunge aficionados likely won’t be able to go back to the days of pouring bags of ice into a plastic barrel after they’ve experienced what chiller units can bring to the table.
Portable Hard-Shell Cold Plunge Tubs
While many portable cold plunge tubs are inflatable, there are a few made from plastic or aluminum that can be moved easily from spot to spot. These tubs often weigh less than 100 pounds, which is certainly moveable for two or three people, especially if you have a hand truck nearby.
Unlike heavier premium tubs, these portable plunges likely won’t have chillers or filters built into them. Don’t be fooled, though, because the best ones will still be durable enough for people to climb in and out without worrying about anything breaking.
