The Plunge cold plunge overview
When it comes to finding the best cold plunge for you, there are a few essential features to consider, including cooling capabilities, size, design, and cost. The Plunge checks all of these boxes with a middle-of-the-pack price tag. At almost $6,000, it’s not cheap—but if you’re looking for a sturdy adult-sized tub to enjoy your ice bath, you won’t find one of this value for its price.
With its sleek, modern design and impressive functionality, The Plunge Cold Plunge delivers by providing a comfortable cryotherapy environment for users to enjoy all the ice-cold health benefits. Thanks to the included chiller, which reviewers say is extra quiet, this cold plunge operates at a consistent temperature that can easily be adjusted by an app on your smartphone.
While we appreciate the fiberglass-reinforced acrylic material’s durability and its ability to withstand the elements both indoors and outdoors, the simple design lacks extra frills. But, when you’re mostly focused on preventing freezing, you don’t need a lot more features.
The Plunge app allows you to track your sessions, which is a great feature. And while a phone mount is included—a nice touch for those who need a distraction—die-hard cold therapy enthusiasts know all their focus should be on their body and breathwork. But, if you want to chill with your favorite tech-based distraction, The Plunge provides that option.
The Plunge cold plunge dimensions
The Plunge cold plunge is slightly larger than some comparable tub models we researched. It allows taller individuals (up to 6’8”) to submerge themselves fully, which isn’t possible in some of the smaller tubs or vertical barrel models. The top perimeter of the tub has a length of about 73” and width of just under 33”. In contrast, the actual footprint is several inches smaller in terms of length and width. At almost 27” high, it’s tall enough to hold 100 gallons of water but still low enough for most people to have an easy time getting in and out. This size tub is ideal for home gyms, patios, or backyards without requiring a large dedicated area.
Despite its relatively small footprint, The Plunge offers plenty of room for full-body immersion, allowing you to submerge yourself comfortably. Its design balances practicality and comfort, catering to users who want an effective cold plunge experience without sacrificing too much floor space.
The Plunge cold plunge benefits
The Plunge may provide health benefits related to cold water immersion therapy. Studies have shown that people who adapt to cold water immersion therapy may reduce cardiovascular risks and inflammation in their bodies. ( 4 ) Other studies have revealed improvements in other bodily functions, such as the immune system, circulation, muscle recovery, and metabolic regulation. ( 1 , 2 , 3 , 5 ) Still, this research is early, and more data is needed to validate these claims.
Despite these potential health benefits, the National Center for Cold Water Therapy cautions people against submerging themselves suddenly in water temperatures under 60℉, noting that cold shock—a common physiologic response to cold water—can cause harm even to healthy and capable swimmers. ( 6 ) In addition, the American Heart Association (AHA) states that the health benefits of cold therapy remain “scant.” ( 7 ) Therefore, individuals with heart conditions, among other pre-existing conditions, should consult with their physicians before undergoing cold immersion.

How to use The Plunge cold plunge
Using the Plunge cold plunge is straightforward and user-friendly. Here’s a step-by-step guide to help you get started:
Setup
Begin by placing The Plunge in your desired location. Ensure it’s on a flat surface and within reach of a power outlet. The unit is not designed to be moved around often, so it’s best to choose a spot where you plan to keep it for a while.
Connect the chiller
In order to keep the water cool and clean, you’ll eventually need the chiller to be connected to both the tub and an electrical source. Make sure it has a filter before you turn it on.
Fill tub with water
Using a hose, fill the plunge with cold water until it reaches the desired level. The self-cooling feature in the chiller will maintain a temperature of 39°F, so you won’t need to add ice.
Power on
Plug in the chiller unit and turn it on. The cooling system will activate, ensuring the water reaches the optimal temperature for cold therapy.
Immerse yourself
Once the water is at the desired temperature, step in carefully. The Plunge is designed for comfortable full-body immersion, allowing you to sit or recline and enjoy the benefits of cold therapy. Ensure you have a towel nearby and to catch any water that may drip when you get in and out and to dry off afterward.
Duration
It’s recommended to stay immersed for 3-10 minutes, depending on your experience and comfort level.
Exit and rinse
After your session, exit the plunge and rinse off if desired. The built-in filtration system will help keep the water clean for your next use. You may want to drain and replace the water monthly if you use your cold plunge several times a week, but it can stay in longer if you use it less regularly.

The durable, weatherproof design also adds long-term value, making it suitable for outdoor setups.
How much is The Plunge cold plunge?
The Plunge cold plunge is $5,990 for the standard model. Financing options are also available, allowing users to break the cost into monthly payments.

How many people can fit in The Plunge cold plunge?
The Plunge is designed for individual use, comfortably fitting one person at a time.
