I see at least 5 shades of gray in your last picture. Looks fine to me.

I found that some of the glass tile samples I put on the wall darkened considerably. Yet, away from the wall they were much much lighter or brighter. The difference was astounding. Love your cabinets by the way.

Since you did the research and know the tile isn't true white, not sure why you seem surprised or unhappy that it turned out like the research said it would turn out?

I think it pairs well with the rest of the kitchen. But you got a couple options if you want it changed- either tear it out and replace with a different tile... or cover it up; either paint it or put another tile or something over that tile.

Glass can be tricky. So sorry. You went with a reputable tiler. I guess you weren’t there during install as you have seen this right away.

I imagine it is not the tilers job to know that this color is unexpected.

That said, although not what you wanted, it is NOT a horrible mess.

Is this the only two places that you have tile? The coffee station? Will have appliances in it, the stove will be in and maybe if there is room you can put something decorative.

It is extremely disappointed when you spend all this time and money and things go array.

We have all made errors. Not necessarily our fault.

You have a beautiful kitchen.

This may not be what you want to hear, but I think this was a happy accident and your kitchen is stunning! I think white tile next to the white expanse of cabinets would be too much and the beauty of your cabinets and counters would be lost. But, since you expected a different outcome I hope you find a resolution that brings you joy in your new kitchen. It is truly unique and gorgeous.

Personally I would take it out. I don't think it goes. Yes it's extra money, but your kitchen is stunning, and a solid white backsplash is what you need. Unintended mistakes happen. You will be happier after you change it.

It can take up to 2 weeks for everything to fully cure and dry out behind glass, since it’s non porous. If this was just done, have some patience,

I am not usually a fan of white kitchens with white subway tile, but I think the ‘grey’ gives it an extra edge that is quite beautiful and special.

I have to admit that I immediately ripped out my first backsplash. It really clashed. In OP case they seem to think it will be very expensive to change.

I like June’s idea to wait. Interesting to see if it will lighten. It can always be ripped out at any time.

Gettingnowhere... is right, when you lay it down it looks white and on the wall gray. It’s shocking that it could be this different, I’m waiting to hear back from the company that manufactures. It’s a story of caution... somebody commented that I would’ve known this based on my research but that never came up ... it’s since this happened that I found this appears to happen with white glass in particular. Its certainly not what I intended and I’m not sure going forward what I’ll do ... probably live with it for awhile and I guess we’ll see. What I would like to know is how on earth do you get a white glass tile? I don’t know what more I could have done...

All white kitchens can be hard due to the variety of whites, different color lighting, and glass tiles can be more difficult to work with. Perhaps if you do not like the current outcome you can try another white tile that might work with your kitchen better. Notice the white subway tile we have used here in our design pictured below.

As someone else suggested, it might lighten up as the back dries. As it stands I think it looks pretty good. Personally I don't like glass tile no matter what the color.

This company makes beautiful hand-made tile in up state NY. You might want to check them out if you do decide to change. Complete Tile - true white.

Amy, that looks beautiful...

If you want a real white glass tile, where the whole glass tile is white and not just the backing, then look at Oceanside Glass Tile.

Glass tile with white baking can also tend to turn green once installed.

I’d take it out personally. i am sorry this happened to you. sometimes things don’t work out!

As Chispa notes the Oceanside glass tile is made from white glass so it stays white. I have walls and floors made from this in my powder bath and it is bright white.
