Take out the tile
Welcome to the Bunnings Workshop community @scott6. It's great to have you join us, and many thanks for your question about removing a bracket from a tile.You'll likely find a small hole somewhere around the bracket's perimeter; that could even be it on top there in your photo. Inside that small hole will be a grubscrew. Once you undo this grubscrew with an allen key, you can remove the bracket cover. Inside, you'll find some fixings to remove the rest of the bracket off the wall.Please let me know if you have any questions.Mitchell
