Those X braces between the joists won't support a tile floor.
I'm not talking about the X braces. My way is different.
Ok picture this, you lay 3, 2 by 4's on the floor on edge. They are spaced 16 inches apart. Now, cutting from another 2 by 4 you cut several at 14 1/2 inch length. Take those that you just cut and place them on edge in between the 3 boards. On 90 degree angle from the 3 other boards.
If you do that enough you are strengthening the middle board.
Tile on wood floors suc because you have to have a really strong well structured floor.
Yes I know they don't use fire blocks in new construction. I was just using that as an example. It was a bad example for me to use as I have seen some that were put in at a 45 degree angle.
The bracing I've used is put in at 90 degree.
Hopefully by now his house has burned down and he can just collect insurance! Lmao
