We sourced a chevron tile at Walker Zanger at the SF Design Center, but they were out of stock for the foreseeable future. So we made these custom into the chevron shape. They started out a standard, 12x12 marble tile that you can find anywhere and our tile contractor cut each piece actually saving the client a lot of $ from purchasing a ready-made "chevron tile". We added the dark grout to give the shape more contrast and impact. We kept a tight grout line for a modern aesthetic. :)
