Leveling wood floor for tile

I've got 2" x 6" tongue and groove subfloor in my house. I recently replaced some of the planks in my bathroom because of water damage. The new planks are ~ 1/8" lower in height when compared to the original planks. What would be the best way to level the floor so that I can lay tile in that bathroom?

 

Welcome to the forums. You can use self leveling compound poured across the low spots. When it is dry, you will be using thinset and 1/4" concrete backer underlayment or ditra, so it should provide a good base for the tile.

 

Your going to need to add screws to all the boards then install at least 1/2 underlayment rated plywood over the whole floor.
That T& G is going to flex and is not flat enough to just install tile board over and call it a day.
Tile board does not add any strength to the floor.
The tile board needs to be set in a bed of thinset.
Thinset could also be used to fill in that low spot.
The plywood gets attached with narrow crown staples or underlayment nails.
Every 4" on the edges and from 6 to 8" in the field.
It should not be nailed into the floor joist!
What size joist are under this floor? Undersized, over spanned joist and the floors going to crack.

 

Thanks for your time and help. Take care

 

krf83,

You may be satisfied with the answers, but I'm not sure with which you are satisfied.

For others with similar situations, please don't think you can install concrete backers or a membrane such as Ditra over plank floors. You need to install the proper plywood first as Joe suggested.
