Had a couple of bathroom fitters round today.
The wall is 1750 and baths are typically 1700, so would need a bit of filler at the end (the current bath, which has the shower over, is shorter and the filler is a tile width).
The fitter commented that normally he'd build the whole wall out to pack the gap rather than have a filled edge.
I said that I found the extra bit really useful for shampoo bottles etc and he said "I'm not allowed to leave them out in my house".
WTF???
Do you put your shower products away in a cupboard after you've used them?
