The Number 1 Choice for DIYers
The Rubbermaid 150-Gallon Stock Tank boasts a simple, yet functional design that has become the most popular ice bath for DIY cold plungers. Made from durable, weather-resistant structural foam, the tank is built to withstand the test of time and endure the harshest and coldest conditions, allowing ice to form and be broken up. We think the tank has great dimensions:
- 2.1 ft High x 4.8 ft Long x 3.2 ft Wide
This provides ample space for the majority of people to plunge comfortably. I am 6’1 and have plenty of room to move around, and I believe this is a great solution for anyone up to 6’5.

Ease of Use
One of the key advantages of the Rubbermaid Stock Tank is its simplicity and ease of use. Filling and draining the tank is straightforward, and the structural foam makes it very easy to clean and does not collect mold very easily. The built-in drain plug allows for easy water removal, while the seamless construction prevents leakage.
Portability and Space Efficiency
Weighing approximately:
- 11 lb when empty
- 1,000 lbs when full
The Rubbermaid Stock Tank is very easy to move (when empty) – it’s little bit more difficult to store as it does not fold and must be kept intact. This also means if you are looking to move it across large distances you will need a large vehicle like a truck.
Price and Value
The Rubbermaid 150-Gallon Stock Tank is competitively priced compared to other ice bath solutions on the market. Its combination of durability, ease of use, and affordability make it an excellent value for those seeking a reliable and effective cold plunge experience without breaking the bank. We highly recommend this option.
The Negatives
The tank’s black color, although robust and resistant to signs of wear, unfortunately, causes it to absorb and retain more heat during the summer months. This can make maintaining a desired cold temperature a tad more challenging, especially on particularly sweltering days. Additionally, there’s noticeable condensation buildup which might be of concern depending on its placement. The absence of a lid means that debris or insects can get into the water if it’s left unattended, requiring more frequent cleaning. Furthermore, its bulky design can pose storage challenges when not in use and lacks the aesthetic appeal one might desire for their backyard setting. All in all, while it offers functional value, there are definite compromises in terms of convenience and appearance.
Final Thoughts
For those seeking an effective cold therapy solution without the high price tag, the Rubbermaid 150 Gallon Stock Tank is a game-changer. Its simplicity, combined with durability and customization potential, makes it an excellent choice for both beginners and seasoned cold plungers. A testament to the idea that sometimes, simplicity is key.
