Opting for a more modern fix, the frameless door is the way to go. Even the shower screen option for your tub/shower combo opens the space while eliminating the track for sliding doors. This is a great alternative for small spaces, families with children, or those who simply like an open area while taking a bath. Now we are left with wet spaces or accessible showers where you do not want a curb. A wonderful option is the Duravit Openspace that folds inward when not in use and opens when it is. The perfect solution for small space, the frameless shower door is hinged at the wall and can set you back $3,000 plus.
