Bathroom Tile Problem

Hi everyone,

We were going to re-grout/silicone our bathroom but noticed a couple of things when removing the old material.

The bottom row of tiles, except the one on the very right, doesn't sit directly over the tub flange and instead sticks out over it (pic #2).

When we press on the middle tiles, they move with a bit of creaking. For example in pic #3, an edge of the tile is jutting out, but if we press on it, we can push it back in place.

Could this be a sign of water damage behind the tiles that's pushing the tiles outward? Or, could it be that since the tiles aren't sitting flush with the tub flange, there isn't enough support and they are sinking downward?

Thanks!

What is underneath the tile? IOW, what's on the wall, and what moisture control method was used when building up the wall?

Neither tile nor grout is considered the waterproofing, and some moisture will get beneath the tile, and some could wick up from the bottom edge at the tub.

We bought the house pre-built so unfortunately I don't know which materials were used.

It is not uncommon on a larger tile to cantilever it over the tub's tiling flange. But, if they used something like drywall underneath rather than something moisture tolerant, or didn't put in a moisture barrier behind the cement board, what you may be seeing is either the wood swelling or the drywall starting to deteriorate.

Do you have any homeowner's warranty? Sometimes, the only way to figure out what's going on is to try to pull off a tile. If it's moving, you may be able to get it off without breaking. If that becomes the path, you'd want to cut the grout around it so you don't damage adjacent tile first. See what the others have to say...

We don't have warranty anymore.

Pulling the tile off seems to be the way to go, although I'm not sure if we're up to DIY-ing that. Thanks for your insight!

If anyone else has any thoughts, let me know!
