The Best Stock Tank for a Cold Plunge

Last Updated Sep 11, 2023

The world of wellness and recovery has seen a surge in the popularity of cold plunging, with many enthusiasts converting their backyards and bathrooms into makeshift cold plunges. For those in the know, stock tanks – traditionally used for livestock – have become the primary way for cold plungers who want to save a bit of money but not lose in quality. Stock tanks provide a rustic charm combined with durability, making them ideal for the modern-day cold plunge enthusiast. But with so many options on the market, which one should you invest in? In this post, we’ll dive into the best stock tank for a cold plunge.

Overall Best Stock Tank – Rubbermaid ‘150 Gallon Stock Tank’

Our number 1 recommendation based on price, durability, and ease of use. Check out our full review here.

Price: $200

Purchase this stock tank.

Material and Durability

Constructed from structural foam, the stock tank is extremely durable and very light for its size. We’ve found it to be highly resistant to both weather damage and the common wear-and-tear that can come from frequent use. Unlike some metal tanks, the Rubbermaid’s foam construction means you won’t deal with rust or corrosion over time.

Size and Depth

The 150-gallon capacity is a sweet spot for many. It’s spacious enough to offer a full immersion experience yet not so large that it’s overwhelming in a backyard or patio setting. For solo cold plungers or those who might occasionally share the plunge with a partner, it’s an ideal size. The Rubbermaid Stock tanks also come in many sizes, both larger and smaller, if you do find yourself wanting a bit more room.

Maintenance and Cleaning

With its smooth interior and rounded edges, the Rubbermaid offers a comfortable experience, free from the sharp or jagged edges that some metal tanks might present.

One of the standout features of this tank is its ease of maintenance. The drain plug is conveniently located and ensures quick water changes or cleaning sessions. The smooth interior also means there’s less chance of algae build-up, a common concern for stagnant water.

We also find this tank to be highly customizable if you ever want to upgrade and add a chiller.

Rubbermaid Stock Tank Cover

We also recommend this cover to keep your stock tank lasting longer and to keep any leaves/debris out of the water.

Most Affordable Stock Tank – CountyLine 100 Gallon Galvanized Stock Tank

A very solid runner-up is the CountyLine 100 Gallon Stock tank. Available at Tractor Supply Co, this is a bit cheaper and has some great features. Check out our full review here.

Price: $150

Purchase from Tractor Supply Co.

Galvanized Stock Tank Features

Crafted from high-quality galvanized steel, this tank has both longevity and robustness. The galvanization process adds a protective layer against rust and corrosion, and the metallic nature makes it incredibly strong and built to withstand ice and all the elements. The tank has a drain plug for easy water changeovers and cleaning.

We find it a great size – Smaller than the Rubbermaid 150 Gallon Stock tank but still large enough to fit a person up to 6’2 and 220 pounds comfortably. We love the farmhouse look of this tank and find that it looks very natural and appealing in a backyard setting.

For Bigger Budgets – Grizzly 400

While not technically a stock tank, the Grizzly is worth checking out if you have a bit more money to spend. Check out our full review.

Price: $1,000

Purchase the Grizzly 400.

Features

Built to be a traditional cooler, the standout feature of the Grizzly 400 is its unparalleled insulation capability. With pressure-injected insulation, this cooler is designed to retain ice for days. Translated into the cold plunging realm, this means water temperatures remain consistently cold for extended periods, reducing the frequency of ice replenishment.

Equipped with a gasket seal and robust latches, the Grizzly ensures no unwanted leaks or spills. Also, as with all coolers, this comes with an attached lid. The ergonomic design includes molded handles for easier mobility, meaning it’s lightweight and easy to transport.

Conclusion

Whether you’re drawn to the durable foam construction of the Rubbermaid 150 Gallon Stock Tank or the rustic charm of the CountyLine Galvanized Stock Tank, you certainly can’t go wrong. These options are the best way to take the plunge, embrace the chill, and immerse yourself in the myriad benefits of cold water therapy. Make sure to consult a doctor if you have any health issues/concerns before jumping into cold water.
