Will this work as a replacement? I currently have a standard 33in. x 22in. (Outside dimensions, I have no idea what the actual cut out is?) Stainless Steel sink I am using. I would like to replace it with this Cast Iron sink. Will it be an exact fit or will I have gaps after install?

Riverby Top-Mount Cast Iron 33 in. 4-Hole Single Bowl Kitchen Sink with Accessories in Biscuit is rated 4.3 out of 5 by 10.
Rated 5 out of 5 by from Great sink Got this sink to replace an older stainless steel sink. The upgrade to this cast iron sink is remarkable. The first thing you will notice is the weight. It is heavy and well made. The difference it made in the appearance of the kitchen is outstanding. The installation was easy enough although it is a two person job. I love this sink and I know you will too.

Rated 5 out of 5 by from HAVE IT SHIPPED TO STORE FOR PICKUP! I gave 5 Stars In VALUE & QUALITY - Shipping & Damage Was FedEx's Fault - Kohler is Great Stuff & Gosh How I Love Kohler! Cast Iron Enameled Sink Is Pure Art! I can not sing Kohler's Praises Loud Enough. Quality is crazy good! This Kitchen Sink is about my 3rd now... (Didn't Like the Other Sinks After Install) This Sink by Kohler is One Hefty Item weighing in around 120lbs or so. The first thing that grabs you is the wonderful porcelain enameled surface. It is completely smooth with NO waves or dimpling. OK Now the bad. The 1st sink arrived Via FedEx... Sink was Damaged (Chipped on Corner) Called FedEx & they have a special Deal with Kohler for damages, so they referred me to Kohler. (AS IF Kohler is to blame for their Damage in Delivery) Kohler was beyond professional about the whole thing & referred me back to Home Depot. Now I called Home Depot & WHAM! They were on it! I was advised a second sink was on the way. Unfortunately the 2nd Sink Arrived DAMAGED. This time the Whole corner of the sink was broken. OH Yea Guess who Delivered... FedEx. IF you want this Sink have it shipped to the Store & open before taking possession that way if it is damaged Home Depot will fix it immediately. BTW, I am sit waiting for a sink to arrive UNDAMAGED. One Final thought... Home Depot & Kohler were OUTSTANDING in Customer Support & cost wise it is a good investment & I have a feeling it will last a long time in service to me & my family. If you have any doubts don't, Buy Kohler!

Rated 1 out of 5 by from Enamel coating doesn't last I would highly discourage anyone from buying this sink. It's incredibly expensive, it scratches when any metal touches it, and the enamel coating begins to break down after a few weeks. Kohler warranties the sink against almost everything besides the enamel coating, and for good reason... It doesn't last!!!

Rated 5 out of 5 by from Easy Sink Upgrade Installation was simple! It came with a template so we could ensure the opening was the same for the new sink. We simply disconnected the dishwasher hose, the garbage disposal, the faucet, whatever we needed out of there to put back in. Then we put the new sink in, and it fit like a glove! Sealed around the edges, connected everything back up, only needed to buy a couple things for the plumbing, and we were done! This is a really high quality sink and has made our lives a lot easier. It came with a sliding tray for silverware and cleaning sponges/scrapers, and a stainless steel grate with rubber legs for cups and plates to dry! Genius and works great. We are still renovating parts of the kitchen, but this sink alone is like a big milestone in the project, and helps it feel a lot closer to being complete. Overall we love the sink and have had no issues with it since installation. The sink is really heavy so please please please make sure you have a friend to help like I did.

Rated 5 out of 5 by from Awesome sink !!! I have an older kitchen that I was updating. I needed a top mounted sink , but wanted the farm house sink look/ feel. This sink is fabulous. It looks beautiful, also love the gradual desent to the drain so water doesn't pool. The design is beautiful also water doesn't splash out over the edges. Yeahh!! I had a Brookfield sink for 30 yrs that did a great job of service. I know this will do the same. VERY HAPPY WITH THIS PURCHASE !!

Rated 5 out of 5 by from Beautiful sink! The sink was easy to install and looks absolutely stunning. The addition of a nice single handle pull down spray faucet makes it just perfect. Love the accessories that came with the sink also, allowing you to hide your sponges :)
