Bypass Shower Doors Install Question
Bypass doors are the easiest of shower doors to install, hence why all the box stores sell them off the shelf. Not a lot to know about installing them other than make sure that they are sealed along the inside to prevent water from getting under the tracks and causing mold. This includes where the bottom track meets the verticle tracks . Clear silicone caulk usually works the best as it will not clash with either the tile color or the track color. If there are gaps between the tracks on the outside of the doors where it meets the tile, caulk along there as well. But remember, sometimes less is more, meaning don't caulk just to be caulking. Water wont intrude from outside of the shower. Newer bypass doors have the wheels along the top rail which is supported by the side rails. So, even if they are installed on a fiberglass/acryllic system, the side tracks are merely supporting the top rail and the screws along the vertical/side tracks just hold them upright. I have seen 'good doors gone bad' due to installers 'over caulking'. Not that it hurts the door, but that you now have unsightly caulking spread along the outside, visible edge, of the track.
