dunno about bathroom either, id rather have them as dry & clean as possible
low shelf/hi pass is usually good
de-ess either with a compresion plug in (one of the ableton comps does this in a sidechain way) or just eq (4-7Khz roughly)
generally compression is helpful
play with reverb to get it to sit in the mix right
if all else fails do some extreme eq cuts & bathe with reverb for a distant telephone effect
