We bought this door late last year and we were now at the stage to install it. It is fabulous.  Install was easier when we dry mounted the door with the hinges attached. Marked the four holes on the tile, placed the door out of the way, drilled pilot holes with 1/8 “ Bosch Glass and Tile bit, then widened the holes with 5/16” bits. The plastic anchors were inserted in the holes. Removed the hinges from the door and mounted them without the glass door. Once secured, the door was attached to the hinges already mounted in the wall using two 7/16 “ thick cedar planks ( the kind used for grilling fish on the grill). Why they don’t provide the 7/16” PVC shim, which states is not included, is beyond me. Luckily we had the cedar planks to provide this needed support. For that reason, I’m giving a 4 star instead of a 5 star rating.
