Just trying to price up the various elements for redoing our downstairs shower room. Have just measured the shower tray as 760x960. Have looked at a few sites and can find ones that are 760x900 but not the exact dimensions. Can anyone recommend somewhere that caters for unusual sizes that won’t break the bank or am I best just tiling the last 60mm? Shower is in an alcove so not got an option to change the size. Not started looking at shower doors yet, so presumably going to encounter same problem finding 960mm door!
