I have had a similar terrible experience with Cle. There is perfectly imperfect - different coloring, uneven adherence to the wall to create texture - and then there's scratches, cracks, brown and green spots. The problem isn't that such issues aren't expected in a tile order, but the sheer number of affected tiles - over 25% of my order was like that. If i were to use those tiles on a wall, i'd get something looking like someone took a hammer at the wall, played darts on it, or the tiles had some form of chicken pox prior to installation. Joking aside, customer service was terrible. Not just straight refusal to make any amends, but they were rude and just said I clearly don't know how to appreciate Zellige, so tough luck. Their strategy seems to be to tire you out until you give up. As the OP said, NONE ZERO of their pictures posted on the website show any of these issues with the tiles, at least not to the extent that I have encountered them in my order. Look, depending on surface tile, having a few of them with brown and green spots and cracks may be fine, but imagine half a wall of that. That is what they claim is normal. I asked that they take their normal tiles back and resell them but they refuse to take anything back unless i sent the full order back. Clearly, they know they can't resell the bad tiles. I also want to note that my order wasn't custom or made to order - they had a bunch of boxes in stock when i called to order and just picked a few and sent them to me. Anyway. I burned myself once and it won't happen again. I reached out to a few of their competitors who sell Zellige, presented my issues (which those competitors didn't say were expected!), and ordered the replacement amount I needed. I will never again order from Cle, especially not after their arrogant attitude. It costs nothing to treat each other with respect.

@Christina Olson- THANK YOU for posting pics of your kitchen! I have the same Sherwin Williams Alabaster on my cabinets. I have been tormented trying to get a similar off-white tile or tile that has shades of white and off-white that are similar to SW Alabaster. I had reluctantly chosen Cloe in white glossy rectangles but your pictures have reassured me that white Cloe tiles will work. I am using stainless steel countertops for the perimeter counters and a porcelain slab for my island that is a composite of beach tones- sand, sea-shell orange brown, blue, blue-grey, & copper in the mix of white & off-white - See picture. I love my slab since I got a copper farmhouse/ front apron sink which goes over blue island cabinets. See- picture. I plan on tiling the entire kitchen countertop to the ceiling around my windows so there are no painted walls in the kitchen (cabinets go to ceiling). After reading additional posts, I will buy extra and filter out the tiles that are too grey. I have seen some Cloe white tile boxes with predominantly grey tiles and I have seen other Cloe white boxes that have more off-white variations.

@Lisa Perez You only need to seal the grout, not the tile. Cloe is glazed tile and sealer should not be applied. You are sealing to protect the grout from stains and discoloring and make it easier to clean. It should be done every 6-12 months, depending on how heavy use and washing. If you don't want to see the grout, Custom Brand bright white is a better choice than grey. Make sure you use the matching tile caulk and not grout where the countertop meets the tile, otherwise it will crack. Given your white cabinets, white grout will give you the clean white kitchen look if that is what you are after. Not sure what your benchtops will be, however, with farm sink and black hardware, the modern farmhouse look can certainly call for contrating grout. But in my opinion, is not as classic and may date faster than all white. If you are worried about keeping it clean, the very lightest greys also are close match to the tile, I used Ash in our laundry room. It almost disappears, but I did not use the whitest tiles and omited them. (I posted photos of both above, but photos are never true to life). But almost all the greys available will give you contrast and you will definitely notice the grout more, and the tile will not be the star. It is a different look and doesn't seem to be what you are after. It also depends on how much natural light and what kind of artifical light you have if you can pull off a grey and not have it pull too much focus. If you have tile left, I suggest you make a sample board and try a few different grout options. and hold it up so you can see what it will look like. There is no turning back once you start. If you don't have time or resources for that extra step, go with white (Custom Brand Bright White) and seal it well and often, especially behind cooking zones. Good luck.

@herbflavor @Julie Schmooley Thank you so much for the quick responses. Answers below... Our "contractor's guy" doesn't speak good English, but we got that there's a 1 inch difference (yup) between the height of the windows. It was unclear where and how bad the levels are off elsewhere. There are 5 more windows that continue on the left and around (see new picture), so it is really important that the line continues consistently all the way around and across. Another quote from several weeks ago when I anticipated this problem said that the right, single lower cabinet needs to be shimmied up by 1/4 inch. Not insignificant. I asked for another guy to come out and assess. Not scheduled yet. He seems to be the most knowledgeable, so I am hoping he can fully diagnosis and provide more concrete solutions. These are the tiles we were going with, my concern is that the variation in color may highlight more of the discrepancy. https://www.bedrosians.com/en/product/detail/cloe-ceramic/?itemNo=DECCLOWHI28G&moq=true&gclid=CjwKCAiAs92MBhAXEiwAXTi255pEjDEpJpr-qA7rqhQ7pCPgnWHVAVwo6BwJp2woIRVbPGUqB7LqqxoC7ukQAvD_BwE
