It looks great! It's personal preference on the grout. If you stick with the white, it will highlight the pattern of the tile. If you color match the tile, it obviously will be a more subtle look. (much like it does now, without the grout) I don't think either is wrong. I attached a link to a photo with the white grout for reference.

If you don't want the contrast of white, go with a silvery grout that still is lighter than the tile. I'd want to add definition to the wall by using something that will give you some contrast.

I'd go just a bit lighter than the tile color.

I prefer something close to the tile color -- surely the brick pattern isn't the star of the kitchen! It just ends up fighting with your counters.

I think white would look great...I would definitely go for some contrast.

This is the exact shade of gray glass tile I wanted, but the one we ended up getting came out much much darker. May I have the brand and color of your tile for future reference?

I'm sorry I didn't see your question, Esther, so busy getting kitchen put back together in time for the holidays. The tile is Crystal Glass, the color is Feather and I used 3x12. I ended up using the bright white grout and couldn't be happier. Again, sorry so long to respond.

Nice!

I love this color of your tile, it's exactly what I'm looking for. I see you put the name, but where did you buy it? I'm not finding that manufacturer. Thanks so much :)

snapclick66, your backsplash looks great!

eboanno, I found it with a quick google search: http://www.mosaictileco.com/Series.aspx?seriesid=1188

It looks beautiful! I wouldn't have gone with the white grout but I like how yours turned out!
