Shower tray orientation

[smallsteve]

To make fitting of the trap pipework simpler, I’m considering turning the rectangular tray around such that the trap would be positioned behind the user i.e. the water would flow away from the shower. Is there any reason why I can’t do this / it’s unadvisable?

Nope aslong as the fall stays the same eg to drain
