I would insist on option C and if they damage anything, they need to replace it, since they didnt do it right in the first place. I wouldnt settle, just because, I was worried they may cause damage. You will notice things are wrong, every time you use it, so they should be made right.

Joe will tell you how the install should be done. Find a competent installer and deduct the cost from what you pay the first guys. The sink should also be mounted with a strap mount. Get it right now.

They probably did the negative reveal because it is easier for them. I would chose option C and if they damaged anything that is on them. I can't stand negative reveals. I have a positive reveal.

100% they did it so they could have a 1/8" negative on one side and a 1/4" or anything else on another. And the cuts don't need to be square or parallel or even straight. I wouldn't have these guys do the correction. They've already shown they do not have the skill level needed for a pro install.

“Accessories” imply needing a POSITIVE reveal. Never flush. But, the sink manufacturer provides the downloadable DFX file for their CNC, that programs it to cut to the manufacturer’s specs. It is virtually impossible to screw that up. You get perfect reveal, every time, straight from the manufacturer.

It's a one-day job to drop the sink, recut the cutout for a slight positive reveal, polish the new cutout, and restrap the sink. All with minimal mess and no top removal. Insist please. Have them call me if they want a play by play. 248-842-5693.

Workstation sinks with accessories need a positive reveal. Not flush.

Hi Darin and Pauline, sorry to hear you’re facing this at the end of your project. That’s incredibly frustrating.

I’m a general contractor based in Florida and I’ve seen this issue before. Negative reveals are often chosen by fabricators out of habit or personal preference, but when it conflicts with the sink’s functionality or the homeowner’s expectations, it becomes a real problem, especially if it was installed against the manufacturer’s spec.

You’re right to be concerned about long-term hygiene under the overhang. Flush reveals not only look cleaner but allow accessories like cutting boards and racks to sit properly and are easier to maintain.

Here’s how I’d weigh your options:
Option A (compensation) is reasonable if you’re willing to live with it. Compensation should reflect both the functionality loss and aesthetic compromise. In some cases, that could be $500 to $1,000 depending on your total countertop investment.
Option B (trimming the overhang) might be workable, but it depends on the material. Quartz can be tricky to re-cut cleanly in place and it creates a mess. You’d want assurances in writing that any damage will be repaired or covered.
Option C (complete rework) is the only way to truly correct it, but it’s also the riskiest and most invasive. I’d reserve that for situations where the sink is unusable or resale value is significantly affected.

Ultimately, the right solution depends on how much the issue bothers you functionally and visually. At the very least, the installer should own the mistake and present a fix, not just justify what they did.

Happy to answer any follow-up questions. You’re not overthinking this.
