Thanks for the advice so far. I have to cut a U shape piece that will slot around a stud wall at the end of the shower tray. I have 600 x 300 porcelain tiles and this is the only one i need to cut a slot out of as all the rest have been done with the score and snap cutter. I have tried one of those hand tile saws but would be there all year I have a angle grinder though would this do it? They are 12mm thick and the cut doesn't need to be perfect as skirting or a wall tile will cover it. If this way will cost me more in broken tiles than a electric saw do you have any cheap ones that you would recommend as I will only be needing it for this cut as hire of one is £40.00 for one day anyway?
