Studio 54 Shower Curtain (featuring a vintage Studio 54 image taken by photographer Patrick McMullan), $23.90 on sale, Izola Shower

If you're a renter, you don't have much say in what your bathroom looks like. You can't pick a pedestal sink, or change the hot and cold water knobs, or decide what color tile should be on the floor. Pretty much the only major item in the whole room you have control over is the shower curtain. So choose wisely.
