Woohoo!!
I've still got to wipe down the tile in a couple of hours, seal the floor in a couple of days, re-install the molding and toilet and then re-caulk around the fixtures... but I should be done during my vacation!
Thanks again radio-active, sammm, and dave04 for the help!
It's actually a white-ish tile... don't know why it appears tan in the photo.
