Envelope cuts with a curved wet room screen

[thompsonbrown]

Done a few with mosaics one side and large format the other.

It will be tricky getting the cut right first time.

Can't say I've done one but have just done a wetroom with seamless screen but into the floor.
I would probably approach this the same and cut the shape/curve out of the tray. Once your "top" level is boarded you'd have a flat surface to mount the screen to.
