I have a lot of experience with the frameless units. www.framlessshowers.com
A common problum is the curb being level or sloping out. Tile men forget that water runs down hill. The solution is to silicone to the curb a 1/4" high threshold and seal the ends to not let water run around the ends. Next, there is a clear polycarbonate diverter with double wipe seals on the bottom that clamps or slips onto the bottom edge of the glass door. Trim it so it won't bind when swinging the door. Lastly tap the seal down untill the bottom wipes rests snugly on top of the installed threshold end to end. If you open the double swing door in the water should stay on the inside of the shower. I have had clients throw buckets of water at the inside of the door with no leaks.
A note to Bob... sorry about the Vegas dream home.
I see us working togeather in the future.
