Hi, I am the Scottishflyer from Ebay. For years I have been puzzled why manufacturers did not make bath wastes with a swivel trap. Much easier to fit. Well now they do. Geberit of Switzerland, world renowned cistern and drainage manufacturer, has produce 3 models with a swivel trap, Wait for it, they come with a push button in the centre of the overflow and this pops up the waste cover. It gets better, the trap is only 89mm high which means you can site the bath really low. Also, 3 sizes to suit any bath. You could spend twice the price and not get as good. Peter
