Hi amydolan, we appreciate your interest in our project! The walls were completely finished and primed as the glass tile allows any imperfections from behind to show through. The grout was custom colored to match the tile.

What color is the glass tile? Is it gray or white? I love it! It's gorgeous!!!

Can you use a light gray grout?? Why always white??

Hi Ncantave,

The glass is a white 3x6" Subway Tile. They have used a Virgin white glass tile to ensure that there is no Green hint (that is natural in glass tiles) showing. Virgin white glass costs more than the regular glass tiles.

To keep things simple we offer all our glass tiles for the same price $9.95 a square foot and Free Shipping for 2015.

The attached picture shows how white our glass tiles are: http://www.thebuilderdepot.com/glass.html

People do ask how do you get a really white glass tile. A lot of glass tiles that say they are white have a green hint to them. For those customers I am sorry, it is a lack of knowledge by the person who purchased the glass tiles.
