Hello. My home was built in 1988 and the kitchen remodeled sometime after that; roughly 2000 I would assume. Everything was replaced then (cabinets, granite countertops, all fixtures.) The sink is a white american standard 33x22 composite of some sort (not cast iron) that has seen better days. I bought a new drop in stainless steel, also made by american standard and also 33x22 exterior dimensions. I thought it would be cake to install with it being the same brand and size...nope! The old one came out fine. I have to assume the hole for the sink was cut on site and it is not very nicely done and there was a lot of dust still around it. The new sink, being stainless, has a c-channel around it for clips to secure it to the underside of the counter. My sink hole is not big enough for these. My cut out is 20.25 by 31.5. The new sink needs 21x31.75. So, I am stuck and have a few options: 1. see if I can get the hole enlarged on site. I know it CAN be done, I am just concerned with the cost and the mess. I do not have a grinder to do it myself and I wouldn't exactly be comfortable doing so anyway. 2. try to remove the c-channel on the new sink and secure the sink with silicone only. Concerned here that trying to remove this would distort the lip of the sink making it not sit properly on the counter. Also not sure I can even get this off. 3. return what I have and try to find something that fits in the cut out I have. This is tough as the cut out info is hard to find (many manufacturers do not include this info and only include a cut out template.) What I am seeing now too is that most cut out dimensions are bigger than what I have, even for sinks that are not stainless. Not sure what to do here. I bought a new faucet to go with the new sink as well. I would hate to have to return all of it. For now, I put the old one back in while I try to figure out what to do.
