My son bought a house built in 1955. It's bathroom had pink tile with black trim. I say had because we tore all the tile and wet plaster out except the ceiling. The sub floor is 1 x 6s run diagonally. We are going to use 1/2 inch backerboard and then thinset tile for the floor. My question is this. Should any type of subflooring be put down before the backer board? Thanks Billy Mac

Here is the bathroom before. I'll post the tear out photo tomorrow.

sounds like a nice project billy , If your gonna put down 1/2 inch backer board use thin set under the backer board and use a 1/4 inch knotched trowel
 
LS your reply says to use thinset under the backer board. Why? I hope our project will look as good as yours. Billy Mac :beer:
 
putting the thinset under the backer board makes it super strong and it will keep the floor from flexing and causing the grout and or tile from cracking ..

mainly because you are going over 1x material if you were putting down a layer of plywood you could probabaly get away with out it
 
we did the same type project last year(we had lime green tile).we had to replace stud's and all flooring including joist. its amazing what a little water leak can if you ignore it for 12 years..... its also amazing you can spend 4 grand in a room that is 4x12.

I recently remodeled my bathroom and laid tile for the first time. I used wonderboard; no flex there; that stuff is awesome! I also used thinset underneath the wonderboard. I got the idea from some pros. I'm told it helps "waterproof" the area. A good idea for a bathroom...

My house is only 13 years old and the tile in my foyer is cracking all over the place. They laid the tile right over plywood! So, I'm going to redo that too. Oh well, the projects are never ending...
 
Very nice LS but my son is paying for this so it will be the basics. Soaking tub tile in the tub alcove and tile floor. I'm heading over there now I'll post pictures of the floor later tonight. Billy Mac
 
OK I'm sorry I forgot to take the camera with me. The floor has large gaps between the 1 bys so we're going to put down either 1/4" luan or 1/2' plywood. Then the thinset and then the backer board. Is the thinset used under the backer board the same as the stuff we'll be using for the tile? What should I use the 1/4 ' or 1/2" stuff? Thanks Billy Mac
 
Yep, it's the same stuff you use for laying the tile.

I'd recommend using wonderboard... As for how thick to go on the plywood or wonderboard, that all depends on how high you need to go. Usually 1/4" is all you need, but that's with an existing subfloor in place.

That said, I'd wait to hear back from Lumber to know for sure...
 
BGA is rite the thickness of the hardie backer and plywood plus the thickness of the tile depends on how high the existing floors are in the house and what your trying to
match up to

Are you planning on useing a marble threshold or metal edge or wood transition strip in the door way?
 
The rest of the house has hardwood floors 3/4". We are planning on using a marble threshhold. I have not looked into the threshhold yet, give me some ideas please? Thanks Billy Mac
 
I have not got the experience of the pros on this site but I would recommend skipping the nails on the sub floor and instead use screws before using the thin set on top and then the wonderboard or equivalent.
Good luck Willy
