Square & Rectangular Water Butts

Square and rectangular water butts fit snugly against walls and into corners, so they hold more water for the floor space they take up than a round barrel.

Many come with connection kits so you can line up several side by side. For narrower spots, take a look at our slimline water butts, or see how to link water butts for bigger set-ups.
