I have had a new basin fitted in my bathroom and it has left some areas around the basin needing new tiles. Some tiles were broken (which are now partly behind the new basin) and unfortunately these tiles were not removed before the basin was fitted. Can anyone advise the best way to remove the broken tiles without damaging the basin? There is a small gap around the basin where I could slide new tiles in, if I can get the old bits out, I have spares. Thanks for any help.
