A curtain is a piece of cloth or other material intended to block or obscure light, air drafts, or water. A curtain is also the movable screen or drape in a theatre that separates the stage from the auditorium or that serves as a backdrop/background.

A shower is a place in which a person bathes under a spray of typically warm or hot water. Indoors, there is a drain in the floor. Most showers have temperature, spray pressure and adjustable showerhead nozzle. The simplest showers have a swivelling nozzle aiming down on the user, while more complex showers have a showerhead connected to a hose that has a mounting bracket. This allows the showerer to hold the showerhead by hand to spray the water onto different parts of their body. A shower can be installed in a small shower stall or bathtub with a plastic shower curtain or door. Showering is common due to the efficiency of using it compared with a bathtub. Its use in hygiene is, therefore, common practice.
