Bypass shower doors have two or more panels that slide past each other on tracks, while sliding shower doors have one fixed panel and one door that slides open and closed on a track.
Bypass shower doors are a great option if you want to save space in your bathroom, as they don’t require any extra room for the door to open.
However, they can be more difficult to clean than sliding shower doors, as there are more nooks and crannies for soap scum and grime to build up in.
Sliding shower doors are much easier to keep clean, as there is only one door that moves.
