About 4 years ago I fitted a B&Q shower fitting in the bathroom. It's just the fitting that holds the shower head and that you can slide up and down to adjust the height. Typically they no longer stock this particular one and I'm loathe to drill new fixing holes in the tiles, especially if the existing holes can't be hidden. On the unit I have the slide is a flat section chrome plated plastic moulding (they all seem to be tubular now). The bit that holds the shower head is retained by lugs which slide behind the flat section. It's these lugs which have broken off on my unit. The whole thing as just over 2ft long. It's got a tiny spirit level concealed in the top so that you can make sure it's vertical when you fit it. I don't suppose anyone knows the fitting I mean and if it's still available anywhere? I could take a photo and link to it if that would help.
Thanks John
