Thanks a lot. I tried to post a photo twice but it isn't showing.

I wouldn't be happy with that overhang on the sink.

I am a fabricator. The corner radius is a function of the diameter of the tooling which was used to make the sink cutout. It could've been much less if different tooling or finishing by hand was done. Additionally the overhang is far too wide and creates a surface that will be tough to clean and will be potential bacteria trap. It's possible your fabricator is unable or unwilling to do it any better. When we do an overhang it's usually only 1/16" but can be 1/8" if it's a cast iron sink which have more dimensional variation that stainless steel or composite sinks.

I would be very unhappy -- I hope you are able to work with the countertop company on a solution.

Something exactly like this is one of the reasons (plus others) that I am getting a drop in sink. While the countertop company I am using seems very nice, they are not especially knowledgeable in various installation techniques, which leads me to believe they probably can't make a super great reveal. I figure a drop in sink hole should be much easier :)

When I had my installation done, the company took the under mount sink to their fabrication facility.

A drop in sink is much easier for the fabricator but it has the disadvantage of a visible caulk joint around the perimeter of the flange that sits on top of the counter. I have seen this caulk joint many times looking cracked and yellowed. If the installer takes the time to tape off both sides of the joint (flange and countertop) the exposed caulk can be greatly reduced. Unfortunately many installers use the tried and true wet finger swipe technique which smears the caulk and leaves far more caulk than is necessary. They use it because it's drastically faster than a good pre-caulk tape job.

My sink library is well over 2000 sinks after 19 years in business but we still see another 1/2 dozen or so new ones every month. If the sink is not in our library we take it back to the shop to record it for subsequent programming.

Thank you everyone for you feedback. To those of you who are professionals, is it too late for this to be fixed? What can I do if (like oldryder said) they CAN'T do any better because of their equipment? Is fixing it time consuming? Should the bottom surface of the overhang at the very least be finished (i.e. polished and free of glue)? Thanks again. By the way: this isnt even the granite color i chose and I already decided to let that slide. I don't want to do too much compromising in thing I am paying for. I've never worked with a builder so any advice is appreciated.

Did you tell them they installed the wrong granite? Even if you are
nice enough to let it go, it should be on the record, and they should
know you are keeping track of these issues. If they keep up this type
of poor work, you may to draw line.

Don't let them bully you into accepting things you didn't want or badly done work. Make sure you hold back some money you owe the builder, so you have leverage if there are more problems.

Search for older posts here were people discuss "sink reveal". There should be several photos of sinks, which you can show to the builder.

Here is one thread , but there are many more:

Wow, they got the color wrong AND botched the sink cutout. Sounds like a do-over to me (and, as a fabricator, I hate saying that.) Good luck.

Thanks again to you all! I noticed both the error with the granite color and the issue with the sink yesterday (only minutes before I posted here). I thought I would let the color issue go to save time, but I still planned write up a complaint and send it out including all of the things I mentioned here. Because i have never done this before, I figured I'd ask around and get an idea of what was normal before I went off on someone:). Thanks!

Have them pull the sink and make a cutout with a slight positive reveal. That thing you have is a ledge that hides crud. A flush mount creates an elongated silicone joint that gets too thin and starts to fray and looks horrible. None of this is possible with a slight positive reveal. Virtually no exposed silicone, no crud, no maintenance.

It's a little hard for me to see the detail of the sink above. Approx how much of a positive reveal do you have there?

That's about 3/16"-1/4".
