I'm looking to replace a pair of taps on an on old 1980's bath (and before any one asks i don?t want to replace the bath). I am interested in a single tap with hot and cold being delivered via the existing holes. (Where the current single taps are). All the web sites just keep saying the taps will fit any "standing bath" my question is how far apart should the holes for the tapes be, and have the standards changed since the 1980s?
Thanks
