Re: leaking shower track
Pay attention to Houston's point #4. You can't seal water out of a space, but you sure can seal it in. Any water that gets in between the track/jamb and the fiberglass unit -- and it will get in there no matter how you try to keep it out -- will need to have a way to get out. It's better if it goes to the side with the drain.

I have read several books on various home improvement topics. I do not have any current code books I can refer to. I was an apprentice plumber for two years.
