Its structural foam construction resists weathering and cracking, extending service life in sun, wind, and seasonal temperature swings. The design features stepped sidewalls that resist bowing, helping maintain a stable, level surface during crowded movements. Versatility is a highlight: users note it can serve as a water trough, a portable wash basin, or a temporary pool for animals. The 50-gallon capacity makes it easy to move and position as needed on a busy farm.
Key features:
- Multi-purpose 50-gallon stock tank for water, cleaning, or as a makeshift pool

- Strong construction with stepped sidewalls for stability
Rubbermaid Stock Tank 100-Gallon: Mid-Size Versatility

The 100-gallon tank offers a balance between capacity and manageability. Its structure is designed to withstand daily farm life with weathering resistance and a leak-proof, seamless design to prevent drips at joints. This size is a common choice for sorting tasks, temporary pen formation, or as a larger water trough in a confined area. For operations needing a longer service life, the model’s durable material reduces the risk of cracks from UV exposure and temperature changes. It pairs well with portable fencing and temporary pen setups.
Key features:
- Multi-purpose use with ample capacity
- Durable, weather-resistant structural foam
- Leak-proof, seamless design to prevent leaks
Rubbermaid Stock Tank 300-Gallon: Heavy-Duty Choice

For larger herds or operations requiring substantial crowding-area capacity, the 300-gallon tank is a robust option. Its heavy-duty construction and structural foam ensure long-term durability in open environments. The tank’s size supports multi-animal handling tasks, from crowding to basic veterinary checks, without frequent repositioning. As with other Rubbermaid tanks, the design emphasizes weather resistance and a seamless interior to reduce debris buildup and cleaning time. Stability is enhanced by the stepped sidewalls, which help the tub withstand pressure from moving animals.
Key features:
- Large capacity suitable for bigger mobs
- Durable, weather-resistant foam
- Seamless, leak-proof interior and stepped sidewalls
Rubbermaid Stock Tank 150-Gallon: Durable Mid-Size Option

The 150-gallon model sits between smaller and larger options, offering substantial capacity without the footprint of the 300-gallon tub. It is designed for rugged outdoor use, with structural foam built to resist weathering and cracking. The unit’s sturdy construction and the stepped sidewalls provide added stability when animals crowd or lean against the sides. This size is popular for temporary crowding setups, routine handling, and as a reliable water or cleaning basin in a fixed location.
Key features:
- Multipurpose 150-gallon stock tank
- Durable structural foam and weather resistance
- Stepped sidewalls for stability
Buying Guide: Key Considerations For Crowding Tubs
When selecting a crowding tub for cattle, consider the following factors to ensure the best fit for your operation:
- Capacity vs. herd size: Choose a size that matches daily handling needs. Smaller herds may benefit from 50–100 gallon tanks for rotation, while larger herds may require 150–300 gallon options.
- Durability and material: Structural foam stock tanks resist weathering and cracking, reducing replacement frequency. Look for seamless interiors to minimize leaks and debris buildup.
- Stability and design: Stepped sidewalls help prevent bowing and provide added stability when animals crowd the tub. A low-profile design can reduce tipping risk during handling.
- Leak prevention: A seamless, leak-proof interior reduces water loss and contamination, which is important if the tub doubles as a water trough.
- Portability and setup: Consider how easily the tub can be moved or repositioned within pens or worksites. Lighter options facilitate quick reconfiguration.
- Multi-use value: A tub that functions well as a water trough, cleaning basin, or crowding pen offers more utility, enhancing return on investment.
- Maintenance: Smooth, non-porous interiors are easier to clean and spray down after use, supporting herd health and biosecurity.
- Compatibility with fencing and pens: Ensure the tub can be integrated with portable panels or fencing for efficient crowding and release.
Operational considerations vary by climate and herd behavior. In warm weather, frequent cleaning reduces algae and odor, while in cold months, insulated or sheltered setups help prevent water from freezing. For multi-use farms, selecting a size with acceptable margins for growth and seasonal needs can simplify inventory management and reduce the number of different tubs required.
