Best Galvanized Tubs for Buyers Seeking 100-Gallon Capacity
If you need a 100-gallon galvanized tub, the products listed here do not include an exact match: most are small galvanized tubs, and the largest is a 300-gallon stock tank made from structural foam rather than metal. The Behrens and Little Giant options are better for smaller chores, storage, or garden use. Choose the Rubbermaid tank if large capacity matters more than galvanized steel construction. Check the stated capacity and material before buying.
| Product | Stated capacity | Best suited for |
|---|---|---|
| Rubbermaid Commercial Stock Tank | 300 gallons | Large-volume use when foam is acceptable |
| Little Giant Oval Tub | 16 gallons | Feeding, watering, and washing |
| Behrens Round Tub | 16 gallons | Storage and garden use |
| Behrens Hot-Dipped Tub | 15 gallons | Compact utility needs |
| Behrens Oval Tub | Not stated | Oval-shaped projects |
Rubbermaid Commercial 300-Gallon Stock Tank

Best for: Buyers who need substantially more than 100 gallons and can use a nonmetal tank. The 300-gallon capacity makes this the closest option in the list for high-volume livestock watering, animal care, or other large-container uses.
The tank uses rigid-cell structural foam, which the product description says is designed for durability in different weather conditions. It is made in the USA and comes with a stated 10-year limited warranty.
Limitation: This is not galvanized steel, and its 300-gallon capacity is three times the target size. Avoid it if metal construction or a container close to 100 gallons is essential.
Little Giant 16-Gallon Oval Tub

Best for: Small-scale feeding, watering, washing, or garden tasks where galvanized metal and a manageable tub size matter more than 100-gallon capacity. Its listed features include a heavy-duty metal body, supportive rims, and handles.
The oval design can suit chores that benefit from a longer container, while the classic galvanized exterior also works for patio planting or decorative use. It was selected as a versatile metal option with multiple stated utility applications.
Limitation: At 16 gallons, it is far below 100 gallons. Choose it for smaller jobs, not as a substitute for a large stock tank.
Behrens 16-Gallon Round Galvanized Tub

Best for: Buyers seeking a round galvanized container for home storage, garden use, or entertaining. Its 16-gallon capacity is clearly stated, and the product description mentions uses such as storing cleaning accessories and towels or chilling outdoor beverages.
The offset bottom raises the tub above the ground, a feature described as supporting cleanliness, stability, and functionality. Its wire handle adds a carrying feature for moving the empty or suitably loaded tub.
Limitation: The capacity is only 16 gallons. This is a practical smaller tub, not a 100-gallon option.
Behrens 15-Gallon Hot-Dipped Tub

Best for: Buyers who want a compact hot-dipped steel tub with a stated capacity and dimensions. The product is listed as 15 gallons and measures 21 inches long by 21 inches wide by 11 inches high. Its classic zinc finish gives it a traditional galvanized appearance.
This option was selected for buyers prioritizing a straightforward steel tub for modest utility needs. The stated dimensions can help shoppers assess whether it will fit their available storage or work area.
Limitation: Its 15-gallon capacity is not suitable for buyers who specifically need a 100-gallon container.
Behrens Hot-Dipped Oval Tub

Best for: Buyers who specifically want an oval, hot-dipped galvanized tub for a project. The available product details confirm its material and shape, making it a relevant alternative to round tubs when an elongated form is preferred.
This product is included because it matches the galvanized-tub category and offers an oval style. Its listing describes it as suitable for projects, but provides no capacity or dimensions in the supplied details.
Limitation: Capacity and measurements are not stated here. Confirm the dimensions and volume on the product listing before choosing it for a specific job; do not assume it holds 100 gallons.
Buying Guide: How to Choose a Large Galvanized Tub
Is any option here a 100-gallon galvanized tub?
No. The listed galvanized steel options range from 15 to 16 gallons, while the oval Behrens listing does not state a capacity. The 300-gallon Rubbermaid tank is structural foam, not galvanized metal. If both 100-gallon capacity and galvanized steel are required, verify those specifications directly before purchasing a different product.
Should capacity or material come first?
Start with the requirement that cannot change. For livestock watering or other large-volume needs, capacity may be the priority, but the listed 300-gallon tank uses foam construction. For a metal tub, the listed Behrens and Little Giant products are galvanized steel but much smaller. These options are not interchangeable.
What dimensions should you check?
Compare external dimensions with the space where the tub will sit, and confirm usable capacity for your task. The Behrens 15-gallon model lists dimensions of 21 by 21 by 11 inches. The supplied details do not give dimensions for every option, so check the individual listing before planning installation, storage, or transport.
Does shape matter?
Round tubs can suit general storage and garden use. Oval tubs may fit some longer spaces or specific chores better. Shape alone does not establish capacity, so confirm both the measurements and stated volume before selecting a tub for water, feed, or another load.
Frequently Asked Questions
What is the largest-capacity product listed?
The Rubbermaid Commercial stock tank is listed at 300 gallons. It is structural foam, not galvanized steel.
Which listed product is a galvanized metal tub?
The Little Giant and Behrens options are described as galvanized or hot-dipped steel tubs. Their stated capacities are much smaller than 100 gallons.
Can a 16-gallon tub replace a 100-gallon tub?
No. A 16-gallon tub holds only a fraction of the target capacity and is intended for smaller-scale tasks.
Does the Behrens oval tub have a confirmed capacity?
The supplied product details do not state its capacity or dimensions. Confirm both before buying for a volume-specific use.
