Could we have a picture from farther back?

From what I can see the backsplash doesn't go very well with the new counters so I would replace with a new backsplash. A photo from farther back might change my mind.

It all depends on how much you love the existing backsplash. If you do not want to redo in the future then I would recommend a tile or metallic trim. If you are not married to it then I would wait until you are ready to replace it.

This was not done correctly. IMO. I’m not a tile installer but why the gaps? What is the explanation from installers?

everytime you install new counters and keep the old splash there will ALWAYS be a gap. i see it everyday. Your old counters were thicker than the new (obviously). If your GC was handling everything for you i guarantee he knew there would be a gap.

I suggest you re-tile your backsplash into something that matches better.

I would put a temporary trim piece there until you can retile the backsplash. Unless you can caulk the space instead of the trim piece, but thats a pretty big gap to caulk. Either way whatever you do should only be a temporary fix till you redo the entire splash.

Catt combs, are you saying the installer cound not start the bottom tile on top of the counter? Just curious as to what should of happened.

The counter top sits on the cabinets. If you build up under the stone with plywood you will see playwood exposed ont he entire front. New stone tops are never as thick as the plywood/laminate tops of the past.

Replace the top and backsplash at the same time.

Exactly what @millworkman said.

Go with millworkman's advice. Replace the backsplash, it won't cost that much and you can get something that matches much better. The pink quarry tile doesn't go well with this top.

Clearly you did not read that

Stone tops are never installed over plywood. Never ever.

Ok

Never mind. I've seen a few things done in vintage houses for various reasons, but listen to the counter top pros here. I will remove my comment so as not to mislead.

Thanks everyone. I am disappointed with my GC not alerting me that this would be a potential problem. It would totally have made more sense just to do everything at once. I made a field trip to the tile store and the person there took a lot of time to educate me on options. Batted around the idea of using a liner or pencil tile but when I measured the gap is not uniform. I will be idea hunting for backsplashes on Houzz now.

Beth,,,it's a beautiful countertop. I think you will be much happier w/a new backsplash. yes, the gc should have told you the new counter may leave a gap.

Find a better looking tile that goes w/the new stone. I actually have that same size/type of backsplash and hate it! I'm redoing mine as well.

if you need backsplash ideas, let me know. i'm well versed in what's available. btw, what is your countertop? I can't tell from the smaller picture.

Thank you Beth. It is Caesarstone Vanilla Noir. I chose it to coordinate with my granite island (I have no idea what the name of that is) and the backsplash.
