Steam In Washroom Damages Walls If I Were To Put A Cd Player In The Washroom, Would It Have To Be Waterproof To Live?

If I were to put a cd player in the washroom, would it have to be waterproof to live? - steam in washroom damages walls

I have a radio / CD player in the bathroom, so you can listen to my music while in the shower. I wish on a shelf outside the range set by the water, but steam chaos, if you werent waterproof?
