I am installing this Mira Bath screen.
https://www.plumbworld.co.uk/mira-e...screen-curve-5mm-glass-21814105-2926-1255051#
The instructions from the manufacturer say:
"Always fit the wall channel to the highest point on the bath side."
Now my plumber said to me fit it in the middle of the bath lip.
My bath has a lip that is raised on the outside and deeps on the inside.
What instructions am I following Mira's or plumbers?
