Could someone please advise me how to remove the shower rail so that I can fit a new one. It is different from others as I can not find how it attaches to the wall and when asking the people who built this house I cannot get any answers. The shower rail slider broke and have tried to fit another temporary one however the rail is 18 mm which is smaller than usual and doesn't work very well so wish to remove the entire rail and replace with a new one. If someone can let me know to get this off it would be greatly appreciated.
