Whether the seam should go there or not depends on then layout and size.

I’d say the seam is average - not great and not the worst

Personally I really dislike see in this location as you spend so much time in this loca

If that's supposed to be a color match to the white of the counter material it's a lot off. I'd send this picture to the fabricator and request a repair with the correct color. Would you accept a bumper replacement on your white car painted that grey color? Not a chance.

Not so fast, dan1888. That's a white quartz, some of the most difficult to seam. That may be factory color match; the picture isn't that great. It's a nice acceptable seam nonetheless and it's in the right location.

You want highly inconspicuous? Get Corian.

If there is any fabricator error here, it's failure to properly set customer expectations.

Joe I'm sure you're correct about the difficulty in matching white in this segment of the industry. So the acceptable industry standard match may include this. . . . . . . .

If I were doing the matching I would not accept this. Even if it may be a 'factory' match. It does appear to be a match for the grey. Maybe they forgot to bring the white factory match. There probably are two for this product . . . . . I would want to provide the customer with an actual white match. From the repairs I've seen you post I think your match would not be as noticeable.

The 'factory color for a car has a single code. But when you go to match it the auto paint suppliers to body shops have variances, sometimes 6 or so. Darker than prime, dirtier than prime, and others with a sample card for each to put against the car and make it possible to get the formula right for a very close match.

I’m in the business of developing quartz so my fabricator knew what my expectation was as I set it knowing what is possible.

My seam....

I think part of the problem is that big vertical seam running all the way down the front of the cabinet. I've never seen the fake drawer panel in front of a sink done in two pieces like this one. Usually it is one long piece than spans the width of the cabinet.

Like this photo, which also has a counter seam right at the sink, but the vertical seam is broken up.

I am surprised that no one mentioned the lippage. That bugs me a bit. The color would be better to be lighter IMO. Every time I have had a seam, its location was discussed with me. The one time I can remember the sink being an issue, we elected to not put in in the center of the sink. It was the fabricator's advice and I think I now see why. Lippage somewhere else would not be noticeable.

I don't know how or where you see lippage in that picture, but I do see an excessively fat sink rail, probably to accommodate the sink clips. Had they strapped the sink, that rail could be 3" or so instead of the apparent 5", nearly halving the length of the seam.

The best way to handle the seam would be to appreciate the good cooking and the view of the rest of your home you get when standing at your sink.
