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.

The cement board is right for under-floor for wet areas. Laundry too.

Think carefully about those 12" square tiles, wet underfoot too. 12" of wet masonry with some soap on it can be very slippery indeed, "slightly textured" or not. I'd try some soap and water on it first, then imagine someone's foot slipping on it, before I made up my mind to stick it on the floor. Floor tiles in wet areas are generally smaller because the joints are an important part of the anti-slip characteristics of the floor.

Thanks,
I have some smaller tiles, I'm considering also, their about 6", I was wondering about that also. The washer will have a pan, under it, with a drain hole, just in case. The Dryer is propane and the room will have it's own intake/exaust draft system, not attached to the the rest of the house. The water heater is in the same room and will have a drain also.
If I put tiles, 1/2 way up the walls of the bathroom, can I use regular sheetrock? Or, does it have to be greenboard?
