Hang the ceiling first.

The walls get hung horizontal. You can get drywall in lengths longer then 8' so if you have a room that is say 10'x12' then you will only have horizontal/tapered edges to tape (not counting the corners of course) and they will be in the middle of the wall etc....

By hanging vertically and using longer drywall you will have much fewer joints to tape.

Another tidbit, when hanging over door/window/light fixture/electrical boxes etc... just hang the drywall right over with just a few screws first, then use a drywall router to cut out the openings by using the opening as your guide with the drywall router bit and then finish screwing it on. Makes the job go much faster.

You can use green board on the bathroom walls but not on any walls that will get directly wet (shower walls)

Don't use it on the ceiling either unless you have 12" oc joist spacing.

We were going to use the greenboard behind the shower walls. The walls are preformed plastic, but are in five pieces, two angled corners, the back and two sides. Hadn't concidered getting enough for the whole bathroom. I thought it was only necessary, behind the shower area. The bathroom will have tiles floor and probably have tile half way up the walls, also. Sort of like chair rail height.
The 1/2 inch clearance on the bottom or the rest of the reg. wall board is supose to be for accidental flooding, isn't it?

Green board is just moisture resisitent, not water proof. This is why it is used on the walls in the bathroom and on the ceiling if you have the proper joist spacing, it will not be effected by occasional moisture from steam etc...

Green board on the walls is an OK subtrate for the tile as long as it is not inside a shower or on a tub surround. For the walls and a tub surround use a cement backer board with a moisture barrier, either plastic sheet or felt paper, behind the cement backer board.

A lot of tract homes just use the green board in showers and tub surrounds to save money but over time, 2-7 years, the green board will get mushy and the tiles will start to fall off.

As far as the preformed plastic panels for the shower, follow the manufactures directions. I only have experience in building showers with tile walls and floors.

When you put the tile on the floor, make sure you have the proper substrate.

ajoys,
What type of substrate do I need for the floor? I picked up some 12" x 12", slightly textured tiles and wanted them on the floor. Do I put plastic under them too? We have 5/8 plywood floor, tong and groove, sub flooring now. What else do I need, before we lay the tile?

I would put down 1/4" cement board, then lay the tile on top of that.

Follow the cement board manufactures directions when you install it.
