I don't recall where we got that tile from, but I will tell you this. The tile is glass, and the owner wanted pure glass tiles on the floor. They were told that the tile will likely mold up and that that would be visible through the pure glass tiles (no backing on them). In fact that is what happened. The tile floor had to be completely removed and properly backed tile was later installed, which is what you see in the photo.

The backsplash tile is Oceanside Glasstile Tessera series in the Random Modular pattern in the color Sandstone. Most likely the reason mold was found below the surface of the tile is because the installation was not done properly. All Oceanside Glasstile is approved for floor installation with exception of our non-iridescent finish and twilight finish due to the standards on slip resistance. If you're ever interested in better understanding the installation of our product on floors and it's performance feel free to contact Oceanside Glasstile's Technical Service department, they are incredibly helpful! 877-648-8222
