What Makes the Rubbermaid 100-Gallon Stock Tank a Good Investment?
When shopping for a durable, high-capacity water trough for livestock, the Rubbermaid 100-Gallon Stock Tank stands out as a leading choice among farmers and ranchers. This structural foam polyethylene tank is engineered to withstand harsh weather, heavy use, and the daily demands of cattle, horses, and other large animals. With a 100-gallon capacity and a retail price typically ranging from £200 to £270 in the UK market (or $250–$340 USD), it represents a significant but worthwhile investment for reliable hydration infrastructure.
Why it’s a popular option:
- UV-inhibited material resists cracking and fading.
- Oval shape fits comfortably in paddocks, stalls, and pastures.
- Lightweight at approximately 27 kg (60 lb) when empty—easy to move for maintenance.
- Rust-proof, non-corrosive design outlasts metal alternatives.
This tank integrates well with automatic waterers and frost-proof hydrants, but proper planning is essential to maximise its lifespan and performance.
How Durable Is the Rubbermaid 100-Gallon Stock Tank in Real-World Conditions?
Durability is the primary selling point. The tank is made from structural foam polyethylene—a material that flexes under impact rather than cracking. While a direct hit from a heavy tractor tyre or a horse’s kick may cause minor deformation, the tank typically returns to shape. It resists rust, rot, and chemical damage from common supplements such as copper sulphate used for Rubbermaid 100-Gallon Stock Tank Algae Control: Effective Prevention and Treatment Methods.
Temperature extremes are a real concern in many regions. The material performs well from -30°C to +50°C (-22°F to 122°F), though in prolonged sub-zero conditions, water can freeze inside. This is where Rubbermaid 100-Gallon Stock Tank Freeze Prevention: Effective Tips for Cold Climates become critical. Many users report that with proper insulation methods, the tanks survive multiple seasons without structural failure.

Owners in areas with heavy snowfall or extreme sun exposure note that the tank’s performance can degrade if not properly maintained, but overall, the tank often lasts 5–10+ years with basic care.
What Capacity and Size Best Suit Livestock?
Choosing the right size tank ensures that your livestock have ample clean water without excessive waste or stagnation. The 100-gallon Rubbermaid tank is ideal for herds of 10 to 20 adult cattle or 20 to 30 horses, assuming a daily water intake of about 10–15 gallons per animal. For smaller herds or calf-raising operations, the same model can serve as a manageable option.
Physical dimensions (102 cm long x 28 cm wide x 53 cm deep) allow several animals to drink simultaneously. The depth makes it safer for younger animals—no steep sides are more than 53 cm (21.5 inches)—reducing the risk of accidental drowning.

How Does the Rubbermaid 100-Gallon Compare to Metal or Other Plastic Tanks?
While the Rubbermaid 100-Gallon is a top contender, it’s not the only option. For those considering alternatives, check the Rubbermaid 100-Gallon vs. Tuff Stuff 200-Gallon Stock Tank: Which Is Right for You?. Tuff Stuff models are often heavier and may require more groundwork. Meanwhile, Beyond Polythylene: Alternative Materials for Your Rubbermaid 100-Gallon Stock Tank explores options like galvanised steel, concrete, and rubberised fabrics—each with trade-offs in cost, weight, and thermal performance.
Comparison Highlights (at similar price points):
- Galvanised steel: Less expensive initially (£100–£150 / $120–$190) but prone to rust over 3–5 years. Heavier (45–60 kg / 100–130 lb) and more difficult to move.
- Concrete: Extremely durable but virtually immovable and can crack from freeze-thaw cycles. Requires annual sealing.
- Polyethylene (Rubbermaid): Best balance of weight, durability, and cost. UV-stabilised but may degrade faster in direct desert sun over 8+ years.
- Rubber: Higher cost (£300–£400 / $370–$500), heavier, but excellent impact resistance.
The Rubbermaid offers an unbeatable value for its weight and longevity in typical farm conditions, though it does require some thermal management in freezing climates.
What Installation and Maintenance Is Required?
Installation is straightforward. The tank is supplied with a pre-drilled drain plug hole (¾-inch NPT) and a smooth interior that is easy to clean. Place it on a level, firm base—cinder blocks, compacted gravel, or a concrete pad work well. If permanent plumbing is desired, attach a frost-proof hydrant or float valve.
Installation steps:
- Clear and level a 4-foot by 3-foot area.
- Lay a base of crushed stone or concrete blocks for stability.
- Position the tank and attach drain plug (hand-tighten).
- Connect water supply if using automatic fill.
- Fill and inspect for leaks around plug threads.
Maintenance focuses on water quality. Regular cleaning prevents biofilm buildup and promotes animal health. Follow guidelines in Rubbermaid 100-Gallon Stock Tank Water Quality Maintenance: Tips for Clean and Safe Water for proper sanitisation schedules. Most owners scrub the interior monthly with a stiff brush and a mild bleach solution (1:10 ratio) then rinse thoroughly.
What Owners Say About the Rubbermaid 100-Gallon Stock Tank
Reviews from farmers and ranchers paint a picture of a reliable workhorse. Here are common themes from across the UK and US:
- “Lasts through the worst winters” – A beef cattle operator in Yorkshire reports his tank survived -15°C winters for 7 years with only one minor crack from ice expansion, fixed with a polyethylene patch kit.
- “Easy to clean and light enough to tip over” – A horse breeder in Kentucky appreciates the smooth surface that prevents algae cling (though algae still grows in warm months, requiring intervention).
- “Better than galvanised for hoof wear” – Multiple owners note that horses don’t chew or kick the plastic as aggressively as metal, reducing denting and noise.
- “Wish the drain plug was sturdier” – Some users report the plastic thread can strip if over-tightened; metal replacement plugs are available for durability.
- “Fits in tight spaces” – The oval shape allows placement in corners of stalls or pens without wasting space.
Negative feedback is rare but focuses on two areas: in extreme sun (Arizona, Texas), the surface can become brittle after 6–8 years, and the tank can flex excessively if overfilled on uneven ground. Overall satisfaction remains high, with 4.5 out of 5 stars across major retailers.
