I was just cleaning bathroom whilst waiting for washing machine repair man to come and we have a triangular shelf in the corner over the bath. I was cleaning it, and it fell off, and bashed into the bath, and has left a bloody dent and I think might have cracked the bath. Is there any way to repair this? Totally at wrong time, as dishwasher broke the other week, washing machine broke on Sunday, and we've just paid £1K to get some external repairs done. REally don't need a broken bath!
