Believe it or not, I've been looking for a way to listen to my iPod in the bathroom without having to worry about the steam/water damaging my player. So when I saw this device on Techie Diva's site, my eyes lit up. The iSplash allows you to listen to your iPod (or other mp3 player) in the shower by wireless transmission. Using a 900MHz dual-frequency PLL transmitter, it sends audio from your iPod, mp3 player, stereo, TV, etc. up to 150 feet through walls, and floors to the wireless speaker. Your device is connected via Zipconnect modules to make this all happen while the "splashproof" speaker hangs from the showerhead.
You can purchase this device from Sharper Image for $129 and it works with all iPods and many other devices. The company also assures us that no matter what device comes out to play music, they will create a module for it.
