We completed this bathroom remodeled in Chevy Chase Maryland nearly three years ago.
The wall tile is a 12" x 24" porcelain striad with glass block subway tile as the border. We custom cut the marble shower floor from larger pieces to get the desired size. The shower door is a frameless set up with a transom above the door. We added this type of door because the shower enclosure also has a kohler steam unit that can be programmed to you desired temperature.
