I have a small 30+ yr old small home, built with 2x3 stud in 1977, with standard and not very high quality stuff ( moulding, door knobs, etc )
I'm replacing the original lineleum flooring in the powder room, the main bathroom and the kitchen with 12"x12" ceramic tiles.
The vinyl flooring is on the 1/4 board so it's pretty easy job to get rid of the lineleum without making any big mess.
The dimensions of the floorings are : ( area to work not counting the cabinets )
- powder room : 3' x 5'
- bathroom : 4' x 5'
- kitchen : 5' x 18' ( Kitchen + Nook area )
So now i got 5/8 plywood floor, my question is what would be the most worth material to use for sub-floor in my case?
- Plywood exterior grade : 1/2" x 4 x 8 -> $ 17 per sheet ( Is it strong enough?? )
- Plywood exterior grade : 5/8" x 4 x 8 -> $ 22 per sheet
- Cement board/backertile/Durock : 1/2" x 32" x 5' -> $15 per sheet
- FiberRock : 1/2" x 4' x 4' -> $12 per sheet
Money is an issue because we are planning to move to a bigger place ( Family is growing )
( Also what is the best spacing for those 12"x12" tiles for my areas? I saw there's many different sizes. )
