Sliding shower doors can be installed either on a bathtub/shower unit or on some shower-only units. There is never a need to install a sliding shower door on a bathtub that has no shower since a splash guard is not needed.
Sliding shower doors have framed and frameless. This metal framing provides much-needed structural support for thin glass or plastic and helps the doors slide along the track easier. Frameless shower doors made of thicker tempered glass getting more and more popular.
