Shower Tile Question

[novichoke]

Team -

We've had a lot of ceramic tile in our walk-in shower (1st floor) that has cracked. Usually from a "hard" mopping of the shower.

Appears there is no "backing" on the bottom sections of the tile and a gap / space along the bottom edge.

Should there have been material or some sort of back-up to the tile here?

Can anyone share a code or reference so I can work with our builder?

We have a 10 year warranty on workmanship and this ends in 2025.

Thx all!

Peter

Well there's the problem.

Yes - she's got to be a lot nicer with the mop...

This is California code but you are in Florida. Perhaps someone from Florida can help out.

Note that the pan liner shall extend a minimum of 3 inches above the top of the threshold. So the backing would also.
