Travertine looks incredible. Thats some attention to detail in ALL the right places, for sure. Great pride in that work. We chose silver for our travertine, and these pictures really confirm it was the right call. Clean, Modern, just enough tan hint to keep it from feeling TOO sleek.
Sucks to hear about the pressure test. Thats certainly one step I would put serious emphasis on (which you obviously did), and not relent. Can't close up and finalize without proving the arteries!
