How worried should I be about this Travertine install?

Your thoughts are welcome.

Even I would get banned if I put my thoughts here

i am sorry but that job is as bad as it gets every thing that can be done wrong is in your bathroom. now i would be questioning the integrity of the bathroom contractor if they are willing to leave you with a job that is substandard.*

That workmanship is dangerous!! Rip it off and start again, that's criminal.

If that is what we can see after the tiles have been removed, the rest won't get any better...

As mentioned above .if the adh manufacture wont give a guarantee with the way their product has been used on your job that says it all .best to remove and redo

The bathroom contractor is liable for this.
Good luck to you.
