What'd they say on Friday? (And, that is weird)

Also, in the kitchen forum, it seems fairly common that people don't use the grates after a while. If it wasn't noticeable without the grate, and your only option would be a complete tear out, I'd just take the grate out.

They said they weren't sure and that maybe the manufacturer changed the style of the sink slightly and didn't update the grates. They said I was the first to bring it to their attention and they will follow up with the sink manufacturer and get back to me - but I'm not holding my breath on that...

My wife actually loves the grates so I guess we will have to live with it.

Live with it. You're talking about a huge ripout that would accomplish nothing except some minor esthetics. If it was something that interfered with performance or functionality, I would have a different view, but that's not the case. In addition, have you actually measured to see whether the drain is off-center, or if the grate was actually manufactured slightly off? I tried to check with a ruler held against your photo and it looks like the "centerline" of the grate is a bit off from being in the center.

I think this is being overthought. I am wondering if the drain hole where the drain gets installed is centered on the sink which it probably is. In that case, the drain was probably not centered when they were installing it or it moved when they were tightening it. Fixing that and replumbing the trap is easy to fix, they probably just have to move the drain over and try to keep it centered while they install it.

I took another look at the photo and, although having the grid in the way complicates sizing it up, I think you're on to something there. If you're right, that's a 10 minute fix. I'll be interested to hear what the OP says in response to this.

Hey - not sure if I fully understand. The hole was pre-cut in the sink. All I did was add the Blanco 3-in-1 basket strainer and redo the P-trap to extend it to the new drain location. (Previous sink was a 50-50 top mount) The precut hole in the sink is indeed slightly off center by 1/2" Even if the sink was completely detached from the plumbing the grate would still be off-center to the precut hole.

The hole in the grate is 5.5" from the left and right. The hole in the sink is 5" from left and 6" from the right. The grate is also 2.25" from the top whereas the hole in the sink is 1.75" from the top.

Ah just making sure. There should be mounting clips to support the sink. I doubt they would want to rely on adhesive alone to hold a sink full of water and plates. There should just be caulking in between the sink and the countertop. If they can get the sink off the top and they have the space to pull it out of the cabinet then you might be in luck.

However, it might still not be possible to remove the sink without lifting the top if they cant get the sink out of the cabinet.

Ultimately it is cosmetic and it may not be worth the risk. It still fully functions and your grate doesnt block the stopper.

Are you saying that you're sure the hole for the sink is not in the center? The point vithdude was making is that, if the hole in the sink was larger than the drain tailpiece you mounted into it, you could have tightened down the basket strainer off-center. If, indeed you know that the hole in the sink is manufactured off-center, then nothing is wrong, other than that you are bothered by the slight mismatch of the grate with the drain. I doubt very much that your sink is any different from all the other ones of that model. That type of sink is typically formed by giant presses where the die shapes are fixed in place and do not depend on the skill of an operator to align anything. I think the tail is wagging the dog on this: you are concerned about a relatively minor asymmetry issue that you wouldn't likely have noticed if you hadn't decided to add the grate. I still don't see that this is worth any kind of radical tear-apart.
