Got to replace a damaged bath got a split in it.
Problem is went and bought one asked for a 1680 mm and the bloke in the wholesalers said this is the one you want to which measures 1700 so got to loose 20 mm overall which would be fine expect its bloody concrete walls and going to be a real PITA fitting it. Had a look around numerous sites and no one seems to supply a 1680 mm one anymore, this one was flitted in around 1998 so suppose it might be a metric imperial measurement problem.
What do most people do with this sort of problem saw a bit of the end of said replacement bath or spend ages chipping away at the concrete walls?.
