A water butt is a great way to take advantage of wet weather and be more conscious of the water you're using in your garden. By collecting rainwater in a water butt, you can conserve water while keeping your garden well-maintained and healthy.
Water butts come in a range of materials and sizes and are designed to capture and hold rainwater. With capacities up to 350 litres, they can be a great tool for saving water and providing a reliable source in the height of summer.
In this guide, we give advice on how to choose the best water butt, outline the types available and provide suggestions for the best water butts to buy right now.
How to choose the best water butt
There should be three main considerations when it comes to choosing the best water butt for your garden. These are: size, material and budget.
The size of your garden will influence the size and water capacity you'll need. If space is limited, consider a smaller water butt with a capacity of under 200 litres. Those with small gardens may also benefit from having a water butt that mounts on the wall to reduce how much patio space it takes up. For a large garden, a capacity of 200 litres or more is suitable. In most cases, you'll also need to buy a stand, a hose, and a diverter.
When it comes to materials, water butts are typically made from plastic or steel. Both are extremely durable but plastic water butts are often cheaper and there are recycled plastic water butts for an environmentally-friendly option.

Types of water butts
Most water butts are supplied with a stand and can be placed on the ground in the corner of the garden. However, some water butts can be mounted on an external wall, a good option for smaller gardens where ground space is precious. You can also run guttering from a shed roof into a water butt as an efficient way to harvest rainwater – if you don't have one in your garden, you might find our comprehensive guide to the best garden sheds useful.
Mounted Water Butts
Mounted water butts, like the Pure Raindrop Water Butt, are lightweight and designed to sit on external walls in the garden. Because of this, they take up very little room. This style also provides more flexibility on the height of the tap because you have full control over where, and how high, it's fixed to the wall.
Plastic Water Butts
Plastic is the most common water butt material and a number of recycled plastic options are available. Cheaper than their steel counterparts, plastic water butts come in both the mounted style or the traditional barrel with a stand such as the Cloudburst Water Butt.
Steel Water Butts
Steel water butts are durable and long-lasting. Typically heavier and more expensive than plastic, these water butts are designed to stand on the ground. Traditional barrel water butts also vary a lot more in capacity.
How do I install a water butt?
- Place your water butt next to a downpipe.
- Cut through the downpipe a few centimetres below the top of your water butt.
- Attach a water diverter to the base of the cut in the upper downpipe.
- Attach the lower half of your downpipe to the diverter.
- Many water butts already have one, but if not, drill a hole for the connector hose.
- Attach the connector hose to the butt and the downpipe.
- Collect rainwater as and when you need it.
