So with 1/4″ plywood, you have to be careful the kind that you use.  I recommend the sureply brand of 1/4″ plywood because it is designed for flooring and tile.

A regular sheet of 1/4″ plywood can be problematic. I have seen issues where after tiling over the regular 1/4″ plywood, areas can lift and create cracked tile.  The shrinkage of the thinset can peal or pull the plywood from the original subfloor.

The other option is to go to a 3/8″ cdx plywood.  This has enough structure to avoid this issue


And if you can fix and get that plywood down to the same level…going over top will be no problem
