The market has gone towards thicker, heavier glass with less metal. A popular door is the Imperial slider, which is like a barn-style sliding shower door. The options for protective coatings on the glass have come along way. Shower Guard glass is a glass that we promote. It was actually invented during Desert Storm. They were looking to put a coating on windshields because they were going through so many of them on Humvees. They also realized it had a protective nature against mineral deposits and soap scum. I probably put that on half the doors we install now. There are a lot of different hardware options between handles and hinges, etc. With the frameless shower doors, everything is custom, so you can lay it out and put the door where you want as big as you want it. A lot of glass keeps the shower space open, makes the bathroom feel bigger and incorporates that space into the bathroom and shows off all the tile work that’s been done. People used to want to hide the shower, now they are so nice and expensive people want to show them off.
