A rain barrel captures free water off your roof for the garden and keeps runoff away from the foundation. The right one comes down to capacity, spigot quality, mosquito screening and how easily it links to add more storage. We compared three — a flat-back linkable 50-gallon, a value 50-gallon that sits against a wall, and a larger 65-gallon decorative barrel with a planter top — on those points plus looks and price. Here's how to choose a barrel that actually holds up, from a compact starter to a high-capacity centerpiece.
A durable, mosquito-safe 50-gallon rain barrel that captures downspout runoff for free garden water. The screened top blocks debris, and a linking kit chains extra barrels. Expect trade-offs: 50 gallons fills fast in a storm, low pressure runs only drip or a watering can, not sprinklers, and you'll need blocks to raise the spigot.
- Rainwater harvesting
- Containers
- Flower beds
Pros
- Flat-back design sits flush to the wall; screened top blocks debris and mosquitoes and is child/pet-safe
- Two spigots plus an included linking kit to chain extra barrels for more storage
- Rear overflow port directs excess water down and away from the foundation
Cons
- 50 gallons fills fast in a heavy storm - you need the overflow routed or a second barrel
- Low gravity pressure won't run sprinklers, only gravity drip or a watering can
- Needs blocks or a stand to raise the spigot high enough to fill a can
A practical, well-priced 50-gallon barrel for small yards: the flat back tucks against a wall, a fine mesh screen keeps out leaves and mosquitoes, and a proper brass spigot resists stripping. Linkable ports let you daisy-chain a second barrel later. Fifty gallons fills fast in a storm and the wood-grain plastic is more functional than fancy, but as a starter barrel it covers the basics well.
- Small yards
- Against the wall siting
- Linkable storage
- Value
Pros
- Flat back sits flush against a house wall to save space in small yards
- Brass spigot and fine mesh screen resist stripping and keep out debris and mosquitoes
- Linkable ports let you connect a second barrel for more storage as needed
Cons
- 50 gal fills fast in a real downpour, so the overflow does real work
- Molded 'wood-grain' plastic looks less premium than a resin decorative barrel
- You still supply a downspout diverter or elbow to feed it cleanly
A larger, better-looking barrel for yards where appearance matters: 65 gal of durable double-wall resin with a removable crown planter top so it doubles as a flower pot. It ships ready to use with a brass spigot, screen guard, overflow and a 6 ft hose. It's tall, heavy and pricier than a utility barrel, and the decorative top catches less water than an open lid, but it's a handsome, high-capacity pick.
- Larger capacity
- Decorative yards
- Planter top
- Durability
Pros
- 65 gal holds more than most single barrels and the double-wall resin is rigid and durable
- Removable planter top hides the barrel and lets you grow flowers right on top
- Comes ready to use with a brass spigot, screen guard, overflow and a 6 ft hose
Cons
- Tall and heavy, and once full it's essentially immovable, so site it carefully
- Costs more than a plain utility barrel of similar capacity
- The narrow decorative screen opening catches less roof water than a wide-open top
Frequently Asked Questions
- What size rain barrel do I need?
- A 50-gallon barrel is the common starting point and fills from just a fraction of an inch of rain on an average roof — so it fills fast in a real storm. If you water a larger garden or want a buffer between rains, go 65 gallons or link two barrels together for more capacity.
- How do I keep mosquitoes and debris out?
- Use a barrel with a fine mesh screen over the inlet (all our picks have one) and keep it intact — that blocks leaves and stops mosquitoes laying eggs. Empty the barrel between rains when you can, and if standing water lingers, a mosquito dunk (Bti) is a safe control.
- Do I need a downspout diverter?
- Usually yes. A diverter routes roof water from your downspout into the barrel and sends the overflow back down the spout, which is cleaner than an open top and reduces splashing. Most barrels, including these, are sold without one, so budget for a diverter or elbow kit.
- Can I drink rain barrel water or use it on vegetables?
- Don't drink it — roof runoff picks up debris, bird droppings and material from shingles. For vegetables, most guidance is to water the soil rather than the edible parts, and wash produce before eating. It's ideal for lawns, flower beds and ornamentals where potability isn't a concern.
