Shower scrubber

LOOFA

This rough, dried plant fiber often hangs in bathrooms for exfoliating skin.

"Shower scrubber" points to a loofa, the rough, sponge-like tool used for exfoliating skin in the bath or shower. The word itself comes from the plant (also called luffa) whose dried fibers create the scrubbing texture. It’s a straightforward clue—no wordplay—just a common household item named directly. If you’ve ever used one, the answer likely popped right into your head.
