Floor & wall tiling

I am tiling the floor & walls to a shower room. I have read it is better to tile the walls first, mainly to keep any mess off the floor tiles. However, I need to place the shower tray at a precise level in order that the front panel will fit without a gap. I propose to tile the floor first therefore. Is this the correct proceedure?

If you can give the floor 10 days to cure well before starting the wall construction, go ahead and do the floor first. Cover the floor with cardboard held down with blue non-stick painters tape so you don't mess it up. You are right about the general rule of walls done first, but you can counter the reasons by letting the floor cure and keeping it covered. Never use mastic to install the floor tiles- otherwise you'd have to wait
