You can use cement board with either a barrier behind it or redgard over it. While redgard is waterproof, it is not entirely vapor proof. Water vapor can still get through it in certain situations and once it gets to the greenboard you may begin to have problems. Hey Sam,

I'am redoing the tube/shower walls in my bath room. I didn't do any research before I started the job. Removed the old wall sections that needed to be replaced and put up green board. NOW I'am online checking out how to tile the walls. Well I should have been ONLINE before I started this job!! My question is can I use Redgard over the green board before tiling the walls or do I have to take the green board out and use cement board with plastic sheeting behind it? Thanks Sam Help Rodger.

Be sure to take into consideration the thickness of the jamb with the tile installed on the inside wall - it'll be more than 5". You can either silicone or tape and mud the transition between the backer and the greenboard. I normally cut the bullnose down to half the width and place them back to back.
