Anyone have any suggestions? I was recently asked to install a pocket door in a relatively small master bath where one side of the wall I would be installing a tile tub surround ( quartzite natural stone 1" x 2" brick lay mosaic) approximatley 30" x 5'. Is this feasible? Also, the wall is of actual 2" x 4" dimension with lathe and plaster as well as a plastic tub surround. So I believe I have approximately an extra 1.5"s of room to work with. I was considering installling a floor to ceiling sheet of 3/4" plywood (glued and screwed to the pocket door verticals) to install the 1/2" hardibacker over to improve the overall stability of the wall to accomodate the weight. Any sugguestions??
