A steep learning curve because as he says, the instructions are very spotty. The doors are so thin, that I chipped a corner just lifting it over the curb during installation. The frame is very flimsy. The frame will distort at the bottom when the "curb" is snapped into position. It didn't help that they sent me the wrong frame size for the packaged doors, so I had to cut 6 times, including the towel bars. Lot's of filing to shape the side rails for the curve of the tub edges. Despite how handy I am with a full workshop, this turned into a nightmare. I can fly an airplane in instrument conditions and install parts in my plane, but deciphering these instructions and making it all work took a long long time. Then you have to caulk it...and tape it..etc etc. Good luck.
Am in the process of installing same door (Arizona shower door) in wlak-in shower but having trouble figuring out the correct dimensions to set wall jams using their formula sheet. Any thoughts would be welcomed.
