For this reason ceramic and porcelain tile floors can be considered somewhat delicate despite the inherent strength of the material.
Subfloor for bathroom tile floor.

The bathroom floor is constructed of the mesh concrete mud then tile.
This adds to the cost of the project but it s better to pay a little extra during installation than it is to tear up a failing tile floor that has.

There is no subfloor.
The plywood will expand and contract at a different rate as the tile causing cracks to develop in the grout lines or tiles over time.

Tile floors are especially heavy with layers of cement board mortar tile or stone and grout.
That usually means the underlayment and the subfloor also get wet.
Plywood is made by gluing alternating layers of wood veneer.
Kitchen cabinets or bathroom fixtures above can also add to the dead load.
