I will probably never look under the sink again. it was so hard for them to take the ugly one out, I'm pretty sure this one is good. They came back hours later because they forgot the grids of course. The installer a very large man demonstrated that it was not budging. Today my remodel will be complete and I will have a fabulous kitchen even though I rarely cook. lol Thanks again everyone!

I am not understanding what OP wants to happen in terms of expectations. Remodeling is frustrating but there seems to be no damage done since the stone wasn't cut and therefore the issue isn't whether OP is going to be forced to accept the stone. It's obvious the stoneyard/installer should refund the deposit and I am assuming will be happy to do so. It seems to be a perfect example of mutual misunderstanding resulting in no contract formation - the classic case regarding the mistake in which ship named Peerless would be used to ship the cargo. Since there was no meeting of the minds, there was no contract :-). It's certainly fun when something that I learned in the first weeks of law school still has relevance in the modern world - I am waiting for a post on caveat emptor and medieval sexual enhancements :-). Ruffles vs Wichelhaus A good example that illustrates what is a mistake in contract law is the case of Ruffles vs. Wichelhaus. There was a contract to ship merchandise on a vessel named Peerless. However, the parties involved had a different understanding of each other. Each party was referring to a different vessel, and therefore, they did not agree when to ship the merchandise. In this case, both parties thought they were in consent until they realized were both misguided about each other’s different meaning. As such, an agreement was not formed since there was no mutual assent between the parties involved in the formation stage of the agreement. Like a unilateral mistake, the best practice to avoid a mutual mistake is to consult an experienced attorney to determine whether a defence of mutual mistake is a viable option for you.

I'm sorry @Nermin Rogers, I went back and re-read Joseph's comment, and his wording was a little misleading which made me misunderstand. At first he says the sink is "properly installed," but he is meaning the sink itself. Then he goes on to say in essence that the faucet should have been installed on the deck and that moving it will not allow any type of inconspicuous patching. I got sidetracked by the "properly installed" statement. You can see at the link he provided that the deck is labeled a "faucet deck" here: https://www.karran.com/product/hampton So, that takes us back to the fact that your installers messed up. A new countertop should be their responsibility to fund and replace. This is the time to switch sinks if you aren't happy.

They should have cut it wider and had less of a gap. Is that really granite? Looks like quartz, but still cut too short? They were even too dumb not to cover up their mistake with some color matched caulk!
