I'm concerned glass tile is becoming dated, so I passed on using it for a backsplash. I do like the ones you've chosen, though. Very clean looking.

If the aim is for a spartan, monochromatic look, it's ideal. If in the end you actually want something less sterile (for lack of a better word), you may want to find tile with a bit more variation in texture, tone, or both.

Kind of boring.

I hope that you will post a photo when it is done. I am considering Bianco Drift for my remodel, but was considering white subway tile for backsplash. I saw an installation at The Kitchen Store in Culver City and liked it.

Go for it. Keep the grout white, contrasting grout is too busy.

I think you did a nice job picking out your materials. I am sure it will be beautiful in the end.
