The masses (thank you Pinterest) have spoken, and it seems as though grey subway tile is in high demand!
Type: Hi-Line Series
I did call the good folks over at Millers Interiors today to confirm that the line still existed (we ordered it back in Dec 2011), and he wasn’t positive on the color but said for sure this series is still in existence.
Hopefully that answers your questions! As always, feel free to shoot me an email or leave a question in the comments and I can get back to you shortly!
