DIY Depot stores do usually stock decor items but you would be best advised to visit your local DIY Depot – or a couple in your area – and see what they stock and find out whether they would be able to order anything specific on your behalf.

DIY Depot stores do stock an item called the drill snake – it is very flexible shaft about 10mm in diameter that you insert through the drain. The rotating core is attached to a drill; the other end of the rotating core having a screw-like fitting that is designed to clear the obstruction. When the drill is turned on the flexible wire core rotates rapidly and the screw-like end clears the obstruction. If your local DIY Depot does not have a drill snake in stock, they should be able to order one for you.
