The overflow fitting on a bath . I mean the parts that fit just below the taps which consists of a faceplate and the other part behind the bath .Do they come in different sizes .The one I got from Screwfix..... The facing covers the hole ok but the part that comes from behind the bath is 35mm diameter but the hole is
50mm diameter so there is a lot of lateral movement available .I havent fitted it yet but I can see already that the two parts are going to be hard to tighten up properly . Two thin rubber washers and one thicker plastic one have been supplied although it's not clear where each one goes .If I do use it I can see me having to use silicone and tape to get it tight ,especially if I am fussy about having the part that secures the chain horizontal..
