Hoping not to take this thread too far off topic but since the issue of keeping shower glass clean is being discussed.... Our master bath glass shower has been in use several times daily for the past 9 years. With minimal effort it is as pristine today as it was 9 years ago. We squeegee after each shower but when I clean the bathroom I occasionally wipe over the glass with wet SPENT dryer sheets. A quick rinse and the glass is sparkling! I confess I polish all my glass, windows, mirrors etc. with crumpled newspaper for a really good finish, and I do this after cleaning the showers too. Very quick, great results. Lizbeth-gardener I encountered the same problem when I was helping my brother prepare the house he had just purchased. The shower glass was almost opaque with hard water and soap scum. Nothing would remove it until in desperation I tried liquid toilet bowl cleaner (I prefer Sno Bol), wiped on with a cloth and rinsed well !! If you try it be careful, read the cautions on the container, test a small area and use gloves, that stuff is caustic! It worked really well for us and the glass became clear again.

Dreamline is one mfg that makes a hinged glass door that has a stationary panel which does have a fixed track but the door itself looks to have a plastic sweep attached but no track where you step over the tub. I saw it here on FaucetDirect. The two things I don't care for in this type of set up, no matter who makes it, is that you can't reach in to turn the water on unless you're in the tub, and also that I'm worried about banging the door and breaking it. I'd like to find sliding doors without a track that slide both ways but so far no luck.

We are installing a 36 x 60 cast iron shower receptor and frameless bypass sliding doors. The glass company said they drill into cast iron all the time and it's not a problem. As a preventive measure, I will ask them to add silicone to the underside of the sill mounted center guide to seal out water and prevent rust. Thank you to everyone who commented on this thread - your input has been helpful and informative.
