Designing Kitchens and Bathrooms - Which materails wall/ceiling bathroom

Hi, my question is about which materails to use on the bathroom walls and ceilings.
The ceiling has 16 on center. Should I use 5/8 'rock?

As for the wall...
1. The shower is going to be a poured floor and tiled walls. What does one put on the wall in the shower area? Greenboard? Cement board? Both?

2. The rest of the bathroom? Is regular 1/2 'rock okay?

Do you really want to hold a 5/8 board over your head when you can use 1/2" cieling board.
1. Cement board(better product $, pain to work with) or Dens shield(fiberglass coated sheet rock)
2. Green board(better product $) or standard 1/2"

Good to go.

While 5/8" rock is always better for a ceiling, I'd use 1/2". Unless the framing is all out of wack and you need to do a lot of shimming, no one will ever notice the difference....... and you will have less scrap leftover, not to mention that it's lighter and easier to handle :D

Regular drywall is just fine for the walls and ceiling - no need to use green board unless local codes dictate. Be sure to prime and coat with a good latex enamel [any sheen] preferably a kitchen and bath enamel.

Cement board is the industry standard fort wet tile applications. Use it instead of drywall at the tub surround.

Will you be tiling the ceiling in the shower area?

No tile planned for the ceiling.
