Bypass and barn-style sliding enclosures for showers and tubs
Sliding shower doors solve a specific problem: they need no clearance to open. In a bathroom where a hinged door would swing into the vanity, the toilet or the opposite wall, a slider is often the only workable option.
There are two families. Bypass doors run two panels on parallel tracks so one passes behind the other, which halves the opening but works in tight spaces. Barn-style runs a single panel across a fixed panel on an exposed top track, giving a wider opening and a heavier, more deliberate look.
The trade-off against hinged doors is sealing. A slider has running gaps at the overlap and at the track, so it is less watertight than a well-fitted hinged enclosure. That is fine in a normal shower and a problem in a wet room where water is directed at the join.
