Top Tank Rain Barrel

The Top Tank is built for serious rainwater storage, not just decoration — a 345-gallon commercial-grade tank designed to sit above ground and quietly capture a lot of water from a single downspout. If your existing barrels fill up and overflow before a storm even finishes, this is the size step-up that solves it.

Molded from industrial-strength plastic in a dark green finish, the closed-tank design keeps light out to inhibit algae growth and blocks mosquitoes from breeding inside — a real problem with open rain collection setups. It ships with a Fast Flow brass-colored plastic tap and a downspout connection kit; a matching diverter (sold separately) routes water from your gutter into the tank and lets overflow continue down the downspout once it's full.

At 46.5" diameter and 61.5" tall, plan for a solid, level spot near a downspout with room to access the tap. Weighing in at 66 lbs empty, it's manageable to position before you start filling it.

Free shipping applies only when purchased together with select greenhouse orders. Ordered on its own, or with a greenhouse that doesn't qualify, this item may entail additional shipping — we'll reach out to you as a follow-up to your order to confirm.
