What is a Rain Barrel?

A water butt (also: rainwater tank or container garden) is a usually between 300, 500 and 1,000 liters of water comprehensive large vat for collecting and storing of rainwater. The rain barrel is therefore used as a rainwater collecting tank and as a rainwater storage tank from the cool rain. To buy the Best Rain Barrel check our buying guide.

Rainwater tanks are available in different versions. These vary in shape (e.g., round, square), size or capacity (e.g., 300 l, 500 l), materials (mostly plastic, rare wood), designs (e.g., amphora, rock) and accessories. Some rain barrel is palatable and thus a particularly attractive for your garden. The rainwater collector should also be frost-proof. The tap, lid, and base are the most accessible and useful barrel accessories. How does the rain get into the bin? Connect the rainwater through the gutter of the gutter guard. So the rainwater flows into the container.

Of course, you can also quickly remove the lid of the tone in the rain so that it rains into it. To catch more rain you can, of course, combine the use of several rain tunnels: depending on how much space you have in your garden.

Weather resistant Frost protection: Most of the rainwater tanks can overwinter outside in the garden or on the balcony. Very important: Before the first frost, the tank must be emptied. Otherwise, it might explode due to the water that is in the cold state.

Advantages and disadvantages of keeping a rain barrel


  • environmentally friendly: lower water consumption
  • saving money: Pouring with the rain instead of drinking water
  • saves time: instead of waiting for the water to drain from the garden hose into the watering can, you can fill it comfortably from the full tone


  • Without rain, the rainwater tank remains empty

Available types of Rain barrel

As part of our purchase consultation in the rain barrel comparison, we have compiled an overview of the two different types of rainwater tanks. If you like it practically, directly and functionally, the choice falls on a classic model (mostly green or anthracite). If you want to use your rain barrel in addition to its functionality as a decorative element for the garden, you have a selection of beautiful rain tones in different designs.

An “antique” rain barrel in amphora optics, as well as the rustic barrel in optics, does not initially remind you of a collecting tank for rainwater. The rain barrel in Fels-Optic is also an eye-catcher in your garden.

  1. Classical rain barrel

The advantages of classic rain barrels are:

  • Functional: water storage and rainwater use (garden)
  • Unobtrusive: can be “hidden” behind ivy vines and fits well into a green environment (e.g., bushes)
  • More choice of sizes and capacities (e.g., 30 l, 100 l, 250 l, 300 l)
  1. Decorative rain barrel

The advantages of decorative rain barrels are:

  • Functional: water storage and rainwater use (garden)
  • Decorative: serves as an eye-catcher in the garden
  • More selection of designs (e.g., rock, amphorae, grapevine, planted with flowers)

Conclusion:  The commonality of the two rain barrel categories consists of their functionality. Select the classic model if you are only interested in the function. Choose a beautiful model if you want to enhance your garden with special rainwater collecting bin.
