The directions are vague and almost useless if you are installing on a tiled pan. Also, good luck drilling the holes for the cheap plastic pieces that hold down the threshold under the shower door. They are so close to the glass panels you cant get a drill close enough to drill a straight hole.

Don't buy this item Fine Fixtures Sartodoors

We bought Fine Fixtures Sartodoors 42" x 42" frameless door and regret ever penny and have nothing good to say about the product or company. Beginning with the instructions, they read like they were written by a grade schooler, they are missing key information and leave the installer to interpret next steps, placement of pieces and alignment. The design is very poor with heavy panels secured by tiny screws/mollies and a stabilization bar with the same issues. The door is extremely hard to align so it will open and close properly. I emailed the company with questions and got a cryptic response simply saying "it will fit." I will never buy a Fine Fixtures product again.
