Product Description

Small footprint, smart design: an oval rain barrel with a stone-like texture that tucks against the wall, right where the downspout comes down.
The Graf Terranova Oval Rain Barrel has a flat, oval shape that takes up very little room, so it works beside a patio door, a garage or a narrow side yard. It holds 73 gallons (277 L) and is made from durable, UV-stable PP plastic with a textured grey finish.
💧 Did you know? Just 1 inch of rain on a 1,000 sq ft roof yields about 600 gallons, enough to fill the Terranova about 8 times.
Why Gardeners Fall for It
🪨 Stone-look texture
A textured grey finish that looks at home next to modern and traditional houses.
📐 Fits narrow spaces
Only 16" deep, so it sits close to the wall.
💪 73 gallons of capacity
That's roughly 36 trips with a 2-gallon watering can.
🦟 No mosquito nursery
The closed design keeps mosquitoes from getting in to breed.
🌑 Algae stays out
Opaque walls block sunlight, so your water stays cleaner.
☀️ Built for the outdoors
UV-stable and weather-resistant, with a spigot included.
Why Your Plants Will Thank You
Rainwater is naturally soft and chlorine-free, the way plants like it. Vegetables, greenhouse seedlings, flower beds and potted plants all do better on it than on treated tap water. Every gallon you catch is one less on your water bill, and your garden keeps drinking even during summer watering restrictions.
Complete Your Setup
🔗 Graf Downspout Connection Kit
The must-have. It fills the barrel straight from your gutter (fits round or rectangular downspouts).
Makes draining quick and easy for cleaning or before a hard freeze.

❄️ Winter Care in 3 Easy Steps
Water expands when it freezes and can crack any rain barrel. Before the first hard freeze:
- Empty it completely.
- Disconnect it from the downspout or close off the water inlet.
- Leave the spigot open so any leftover water drains out.
