A shower cubicle is a self-contained unit that is typically made of glass or plastic panels and designed to be watertight. It usually includes a showerhead, a tray for standing on, and sometimes a built-in seat. Some shower cubicles may also have built-in shelves or storage areas for toiletries. The doors of the cubicle can slide, pivot, or open outward, and may be transparent, frosted, or opaque for privacy. Shower cubicles are a popular choice for bathrooms as they provide a designated space for showering and help to contain water and steam within the unit.
