drywall in new master bath

I'm remodeling my home, and would like to move the master bath to an adjacent bedroom, and remodel the current bath as the walk-in closet. My question regards the drywall in the to-be bath. Currently it is basic drywall, i.e. not greenboard. Do I need to tear it out and replace with greenboard or is there some kind of moisture protection which can be applied to existing plain drywall?

It is advisable to install greenboard only on the interior walls - not on any exterior wall. Do not apply greenboard to a shower/tub area but rather use a cement board backer http://www.cgcinc.com/gypsum/cement.dur/welcome.htm

or a Denshield

You could have problems with any moisture or condensation that could penetrate your regular drywall creating problems down the line. Even good paint doesn't provide adequate protection in these high humid areas.

Hope this helps!
