The Gorilla tub medium is a flexible tub that is built to last. It is perfect for use around the home, in the garden and at the stables. All of the wonderful features mean our flexible tubs really can be used for everything. The Gorilla tub medium holds almost 7 gal and is perfectly sized for carrying liquids and is very well-suited for bending under sink spouts to act as a plant waterer or cleaning agent container. It also works great for mopping.
