I have a similar setup in my master bath, I just don't use glass. The shower is so far away it never gets near the monitor so the only problem is condensation directly on the TV. It worried me at first, but it was cheap enough that I decided to just let it go. It's been 2 years so far and I have no issues. The only thing I have not done that I'd LIKE to do is mount the speakers above the tub. I haven't really found (come across, I haven't really looked) an amp that I'm comfortable putting either in the bathroom or in the attic that takes a mini plug. What solution did you use? or is it running off the main amp in the den with just speaker wire?
