So am trying to remodel my bathroom and was wondering if cement board would work better than greenboard as the shower wall? I've read that cement board can be used on floors or kitchen tops but am not sure if I can use it on bathrooms??
Greenboard by all means. It was designed to be used around tubs
it really depends on what is going on top of the board. if I am using ceramic tile around a tub/shower, I use greenboard. If the tile is granite or porcelain, or will be installed overhead, use wonderboard (cementboard). The additional weight of the tiles could potentially pull the green paper away from the Gypsum. Greenboard is easier to cut For anywhere else i would use either greenboard, or regular drywall and mold/mildew resistant paint, and a new more powerful ceiling exhaust.
You can use cement board in damp locations but around here it's quite a lot more expensive than greenboard. Greenboard works well and I used it for my entire bathroom because I love long, hot steamy showers and baths. Without greenboard backing the bathroom can start to grow mildew in the drywall.
Cement board all the way over wall to put tile onto. I ve repaired, tore down and made good money fixing tile that was placed over green board. On a well used shower or tub area the life of green board before it starts to wick in the water and rot is 5/7 years. Not worth the minimal savings to put in green board. The one main key people don t do is to put up a simple vapor barrier behind the cement board and this should be done with green board to. No questions its cement board on walls, floors etc. Any questions you can e mail me through my avatar and check my qualifications there. GL
