Product Description

divider-leaf-green

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).

🚿 Graf Water Removal Kit

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:

  1. Empty it completely.
  2. Disconnect it from the downspout or close off the water inlet.
  3. Leave the spigot open so any leftover water drains out.

Frequently asked questions

Can't find your answer? Our greenhouse specialists are happy to help you choose.

678-408-8222 Email us
Is a spigot included?
Yes. It comes with a Graf plastic spigot (tap), so it is ready to use out of the box.
Will it fit against a wall?
Yes. Its flat oval shape is only 16" deep.
How do I connect it to my downspout?
Use the Graf Downspout Connection Kit (sold separately). Because this is a closed tank with no open top, the kit's collector fits into a hole you cut in your downspout, and a short hose runs from it into a hole you drill in the side of the tank. The kit includes the drill bit and comes in versions for round and rectangular downspouts. Once the tank is full, extra water simply keeps running down the downspout.
Is there an overflow outlet?
No, and you don't need one. With the Graf downspout kit, the overflow stays in your downspout instead of spilling around the tank.
Can I hook up a garden hose?
Not directly to the standard plastic tap, and the tank works by gravity only, so water won't come out under pressure like a faucet. For tubing, add the Graf Aqua Quick 4-Part Tap Kit (fits 1/2" or 3/4" tubing) or the 3/4" Brass Tap with tubing nipple. It works best for filling cans or slow, gentle watering.
Will mosquitoes or algae be a problem?
Graf designed it as a closed system, so mosquitoes can't get in to lay eggs. The opaque walls block sunlight, which keeps algae growth to a minimum.
Can it stay outside all year?
Yes, as long as it sits on a firm, level surface and you prepare it for winter: empty it, disconnect it from the downspout, and leave the tap open before the first hard freeze. The UV-stable plastic resists fading in the sun.
How is it shipped?
It ships free in one carton by UPS or FedEx to the continental US.
Is shipping really free?

Yes. Shipping is free. Locations with limited access, such as islands, are rare exceptions that may carry an extra fee, and we'll tell you before anything ships.

Do you offer a price match?

Yes. If you find the same greenhouse for less from an authorized dealer, call or email us with the offer and we'll review it.

Are you an authorized retailer?

Yes. Mulberry Greenhouses is an authorized retailer, so your greenhouse is covered by the full manufacturer warranty.
