I think it looks okay. There is some yellowing on the tiles - not sure if that is lighting from fixtures or photo or the tile itself. What do you not like? Remember this is not done yet - no switch plates or toasters or anything.

What don't you like? It does not look finished yet to me. It does not even look grouted yet. I think you should wait till it is finished. Honed tile takes a bit of getting used to when not grouted since there are often uneven tiled lines that grout will fill in. Once you are able to add your accents and details to the rest of the kitchen including your stove hood you will see it in a more favorable light.

You need better lighting in the photo. That said, I'm not a fan of real marble against faux marble in most cases. I also see no reason to tile to cabinet top, ( especially when cabinetry doesn't meet the ceiling ) , just to beneath the hood. Maybe a pale gray in a herringbone?

A slide in range without the riser would give you a much better look as well.

IMO you did not need a backsplash behind that range , as for the tile it looks okay and will look better when grouted but I do agree I don’t like real and fake mixed together but I also don’t like honed stone in a kitchen unless it is slate.

The yellowing is the tiles and not caused by lighting, which does bother me. The tile cuts also look uneven but maybe grouting will fix that. Thank you for all your suggestions, I will wait for it to be grouted then decide. Really love the suggestions of gray tiles!

I tend not to specify real marble against engineered quartz mainly because it makes the engineered quartz have that "fake" feeling. And you also have the contrast of honed tile vs. polished counters. I think the finish is causing more of the problem than the tile itself.

I'd rip out the marble tile and go with a polished/glossy ceramic or glass tile instead. Pick up a soft gray from the veining in the counters. Some ideas:

My first backsplash was tumbled slate and it had uneven edges too - grouting helped. That said, I could see how you would be frustrated with the yellowing. Handmade tiles are beautiful! They have a variation all their own that provides interest. You do have to resign yourself to the fact that the color may NOT turn out exactly as the sample looks. And the edges are often varied because they are handcut, so it that bothers you, maybe handmade isn't for you...

I'd probably get a sample of this - white (or there's a gray) with a fair amount of variation.

I like it. I agree with possibly better lighting. For me, it all blends nicely.

Yes, people here always say not to put real next to faux, but in your case, your "faux" amounts to a few veins! For goodness sake.

I would live with this. I do understand the impulse of starting over. I myself tore put my BS a day after it was installed. Sometimes, you just don't know how something will look until it is all installed.

Colors too, look different on all our monitors. Only you can be the true judge.

your tiler grouped most of the yellow ones in that one spot, so hopefully your vent hood covers most of it. If you have spare tile, have him remove the other yellow ones and replace them with the whiter ones before grouting. the yellow will NOT get better.

lower quality marble tile will yellow.

once you get it grouted it will look better. choose a very pale, neutral gray.

If you can, apply a sealer first (tops only, don't let it drip down the sides) before it's grouted.

take some left over tiles and try a penetrating sealer on both. one that enhances and one that doesn't, to see what you like better.

over all, I don't think it looks bad. you've only posted one pic from far away, so I can't comment on the tile job, but I don't think the marble looks bad next to your quartz. I don't like the sliver piece in the corners. that's bad measuring on his part.

don't forget the under cabinet lighting in a 4000K temp. anything lower will cast more yellow.

Is it too late to use the quartz material? Is this the only area that needs a backsplash?
