Typically you would use greenboard in a bathroom. If you were required to use a moisture resistant substrate, blueboard would not meet the ASTM requirement.
The instructions for the USG blueboard specifically state that it is not to be used in areas of high moisture or as a substrate for ceramic tile. Sorry!
Good luck,
Tim
