I'm having my bath ripped out and a shower put in the corner instead. Problem is the standard minimum tray size seems to be 760mm, and from my wall (that the bath butts up to) to where the window frame starts is about 610mm. So a 760mm enclosure would block about 5 to 6 inches of the window and nothing to secure that part of the enclosure. I rang my builder who reckons he might be able to get a 600mm tray. I asked him to try and find a 600mm x 900mm. Does anyone know if they exist? Not only that, but I felt 760mm width a bit too closed in so I don't know how happy I'd be with an even narrower width. Anyone here got experience of shower enclosures?
