Glass shower screen on shower tray

[maverickone]

Hi folks. I could be over thinking this but here go's. Appologies if it's a stupid question.

If I fit a 700mm shower tray and tile down to it I have lost abou 6mm off its width. If I then fit a 700 mm shower screen on the top of the tray, will it not stick out the front by 6mm?

Simple maths says yes

Google the fitting instructions for your proposed screen.

You will find the fitting adjustments and tolerances there.
