I recently finished my kitchen and put in a swanstone undermount granite composite sink and LOVE it.. it never looks dirty even though I have hard water. I did get the tan colored one so perhaps that helps. I have had many compliments on it as it does not look like an ordinary sink.. I'm surprised I don't hear of more people buying them as the cost was quite reasonable. Good luck to you :)

I put in a Silgranite sink, too. I think either that, or a stainless steel is going to be fine... but I went with Silgranite in my case because the appearance of stainless steel wasn't going to work in my vision of my kitchen. (Silgranite comes in a variety of colors.) I love my Silgranite sink! (Actually, I have two, a prep sink as well.) As with strob06, I first learned of them when I joined this website. No regrets.

Hi Haley, Sorry I just saw your comment. Here are some photos I have in my archive. I can take different angles tonight if these aren't helpful. FWIW, 6 months later and we still love this sink. The dark color matches our black stainless appliances, but also just makes the sink more of a shadow, which is good to avoid drawing eyes to dirty dishes! We use the faucet hose+sprayer to give it a good rinse every evening after cleaning up dinner to keep food from drying in place. We've given it 1 deep cleaning (we also have a grid on the bottom, so deep cleaning involved a thorough cleaning of that, too). The water filter is good for filling water to cook or a tea kettle. The soap dispenser is actually really nice because it keeps the counter tidy. The faucet is touch activated (got it before the remodel) and it's amazingly handy. We added an air button for the disposal (which by code has to have a manual light switch on the wall, which for us is not in reach of the sink) and it has never been pressed accidentally and is very useful so I recommend it. The dishwasher air gap is required by code here so no avoiding that!

Sounds like you've studied each option. Composite sinks can stain, and heat can affect their appearance. Fireclay sinks crack if you have a disposal, and sometimes even if you don't. Enameled cast iron can stain, chip, and rust, although people who have them claim they never do - which is more anecdotal than factual. So there are reasons to avoid all three options, especially if you plan to use an undermount sink and put a counter over it. You don't want to find yourself needing to replace your sink. I chose a stainless steel work station form Rachiele, and that's what I would recommend to anyone - quality stainless is a lifetime sink. The best of these have a brushed finish that hides scratches and soundproofing that makes them quiet. Buy stainless - good stainless.
