I am finishing a bathroom wall and will have tile come up to about 4' off the floor. A bay window extends into both the tiels and untiled part. Is the following the right way to finish the wall and window:
Half inch Durock where the tile will go, then greenboard on the upper section. Then finish of the window and put on the casing, overlapping both the cementboard and the greenboard. Then tile to the edge of the casing on the window.
