FCMP Outdoor 55 Gallon Rain Barrel - Best Overall
The FCMP Outdoor barrel combines a UV‑stabilized polyethylene construction with a 55‑gallon capacity, making it a solid all‑round choice. It features a built-in overflow valve, a steel spigot with a child‑proof lock, and a detachable screen that filters out leaves and insects.

Keter 50 Gallon Stackable Rain Barrel - Best Budget
Keter’s stackable design offers flexibility for limited spaces; two units can be stacked to double capacity while occupying the footprint of a single barrel. Made from recycled resin, it resists cracking and UV damage. The barrel includes a 2‑inch threaded outlet, a screen lid, and a built-in overflow pipe. At 50 gallons, it provides ample water for small lawns or vegetable patches, and the integrated handles make moving it straightforward.
Suncast 30 Gallon Rain Barrel - Best Compact
The Suncast 30‑gallon model is perfect for patios or decks where space is at a premium. Its high‑density polyethylene shell is UV‑treated, and the barrel comes with a molded-in spigot and a 1‑inch hose adapter. A removable mesh screen prevents debris entry, and the barrel’s tapered shape helps water flow toward the outlet. Weighing only 45 pounds when empty, it can be moved without a dolly, making it ideal for renters or seasonal use.
Melnor 80 Gallon Rain Barrel - Best for Large Gardens
Melnor’s 80‑gallon barrel offers a high capacity for extensive landscapes. Constructed from UV‑protected polyethylene, it includes a rust‑free brass spigot, a 2‑inch overflow hose, and a detachable lid with a fine mesh filter. The barrel’s reinforced steel frame and lockable caster wheels allow for easy positioning and stability on uneven ground. With dimensions of 48" tall x 30" diameter, it can capture several inches of rain before reaching full capacity.
Rain Harvest Systems 100 Gallon Rain Barrel - Best Heavy Duty
For regions with high rainfall, the Rain Harvest Systems 100‑gallon barrel provides the most storage in this list. Its double‑wall construction includes an inner food‑grade liner and an outer UV‑stable shell, protecting water quality and extending lifespan. Features include a stainless‑steel faucet, a 3‑inch overflow pipe, and a removable lid with a fine mesh screen. The barrel comes with a steel base and lockable wheels, allowing it to be moved even when filled. This model is suited for sizable lawns, orchards, or community gardens.
Buying considerations
What to consider
When selecting a rain barrel, start by measuring the amount of roof runoff you expect. A simple rule is that each inch of rain on a 1,000‑square‑foot roof yields about 620 gallons, so match barrel capacity to your typical rainfall. Material matters: UV‑treated polyethylene resists cracking, while double‑wall options protect against temperature fluctuations and algae growth.
What to consider
Consider the placement and accessibility of the spigot and overflow. A brass or stainless‑steel faucet offers durability, and a screen lid prevents debris from contaminating the water. Finally, think about mobility; barrels with wheels or a sturdy frame are easier to relocate for seasonal cleaning or to adjust the collection point. By weighing capacity, durability, and convenience, you can choose a rain barrel that reliably supports your water‑saving goals.
Questions answered
A 55 gallon barrel can hold about 0.66 cubic feet of water per inch of rain, so a single inch of rain fills roughly 55 gallons.
Yes, most experts recommend a mesh screen or first‑flush diverter to keep leaves and debris out of the barrel.
