I have a shelf in my shower where I sit my mobile phone that plays MP3s. Echoes really well in the tile shower and the phone's doesn't get wet.

Meanwhile, a Japanese company has come up with a splash proofMP3 player for your shower: the Juketower. You plug in your own USB memory card with your preloaded tunes, and use the controls on the top to change the volume or adjust the track that's playing.

I'd just be happy with a bluetooth-enabled waterproof speaker, personally.
