I have recently built a new bathroom in a basement. I have installed a corner shower kit(base only at this time)the glass door kit has two pieces for assembly, one at the base and one at the top. The doors are 1"3/4 from the ceiling, leaving no room to attach the top piece with screwdriver, any suggestions. The instructions call for attaching the two side pieces to the walls, and then placing the shower door and sides to them, and then screwing the top plastic piece to the complete door unit. I have thought of installing a custom white aluminum angle 2" x 3/4, so the angle is on the inside of the shower, and attach this to the wall, then screwing the side upright of one side to the angle piece, thus, securing the other side of the door unit.(there is one door only, centre. The corner shower is a 45deegree door in centre. I would do this after attaching top and bottom secure pieces, and placing the unit in place as one complete section, that way the top plastic piece is in place, and then secure the one side as explained. Could this be my answer?
