I'm trying to decide between a granite composite sink and a cast iron sink.

One reviewer said the lighter colored granite sinks tend to stain. I know that white cast iron can show scratches and marks from pots and silverware. We are coffee & red wine drinkers and between my husband and two sons we need something that can take a beating! :)

I have always had stainless so any suggestions would be helpful!

If you have granite countertops, a granite sink would not be asthetically pleasing. You need to contrast the materials, not match. Just as you wouldn't install a "busy" backsplash over a "busy" granite countertop, you wouldn't install a granite sink with a granite countertop.

Granite can be sealed (yearly) but white cast iron will repel red wine and coffee much better. Just rinse and it's gone. As for metal pots marking the white sink, if the pots are allowed to rub an unlined sink or rub against the sides of the sink, you'll have to scrub to remove the marks.

Granite, being porous is not as clean as a cast iron or stainless steel sink.

Stainless is the easiest but the decision is up to you. Cast iron white looks more expensive. Decisions, decisions. Granite seems cool...

I'd stay away from any composite sink for the kitchen. We purchased a porcelain over composite several years ago from American Standard within a year the porcelain begun to strip off. Never again. I went back to Stainless.

I have been using composite granite sink for 6 years, no issues so far. Composite granite is non-porous, though probably not stain proof as porcelain is. Mine is dark color though, so cannot say if it stains or not. The color is not exact match with the almost black granite countertop, and the texture is different, the sink is matte, the countertop is polished, so look quite good together.

We just had new countertops installed and replaced our cast-iron sink with an undermount stainless steel sink. The cast-iron sink is the best. We had it for 19 years and it was in the house when we purchased it so I don't know how old it was. There were no stains, scratches, or marks on the cast-iron sink. We miss it.

If you love a lot of maintenance then maybe a granite sink would suit you. Keep in mind though, in a few years it will look grungy.

I replaced my old cast iron sink with a granite composite and I LOVE IT! When I did my kitchen remodel I researched quite a few sinks and found that I loved the look and minimal maintenance of the granite composite. I did get the chocolate brown color with a medium to light granite counter top. The contrast is awesome and it is little to no maintenance. I did wipe it down with a little vegetable oil about the 2nd week I owned it and since then all I've ever done is rinse it and occasionally brush over the sides to knock off any food bits that didn't get rinsed off. I been using it since Jan and it still looks new! That is with me only giving it a complete clean about once a month. Perfect sink for those of us who hate to scrub!

I installed a Franke (Swiss) stainless steel sink with my granite countertops and I couldn't be happier with it. The extra price for the Swiss sink was well worth it because it is surgical grade stainless, much more durable than the standard American ones. An additional advantage was that Franke has much larger second sinks so that they can really be used for prep work. If you do a lot of cooking and preparation a double sink is essential. Moreover, always get the largest sink that you can, you always find it easier to clean pots and pans. Many of the sinks that I looked at didn't have enough room to clean a 12 inch pan properly.

I just had our stainless builder's-special sink replaced with an espresso brown granite composite sink. It fit right in the same hole, (over-mount) but is much deeper and more squared, with a corner mounted faucet, so many more dishes/bigger pots fits in it. We LOVE this sink! It's dark, so we don't notice any stains (if there are any) and it "riches up" our laminate countertops (which are a marbled teal color). The brown goes nicely with our hardware, which is oil-rubbed bronze. The listing claims it's an "extremely hygienic" sink, "easy to clean" and resistant to stains, scratches, and acids. That seems to be accurate. We use mostly cast iron cookware, and glass dishes, drinkware, and storage (very little plastic). I say this as a very non-scientific testimonial of it's durability.

I agree with the previous poster: whatever sink you choose, buy the largest you can. My parents had accidentally bought a trough of a sink 6 years ago (granite composite) and almost returned it until I advised them not to. They kept it, under-mounted it in their granite, and have been so happy with it ever since! This is the biggest sink I have ever seen in a home. Very wide. They have no children at home, but they can wash their dogs in it and it comes in really handy at the many parties they have! I find that bigger is better with sinks. You can always cover half of it up with a large cutting board if you need more counter space, and then uncover it when you need more washing space.

Good luck!

Maybe composite quartz or a black concrete sink. I know concrete but you can make yourself and it will be super durable and beautiful.

I've had a black granite composite sink for a year or so now...LOVE IT! Got it from Lowes. It is wonderful...have had zero problems with it. I'm a low maintenance kind of guess from some of the posters here is they have never had a COMPOSITE granite sink. It is not like the typical granite countertops at all. Stainless is hard to keep shiny and clean...white porcelain chips too easily...I've had it all...and LOVE my granite sink more than any of the above! Oh, and I'm a red wine drinker stains at all here (of course, I am using the black is gorgeous!)

1-"Granite" sinks are NOT granite, instead they are ground rocks bound by a polymer resin that holds the little pebbles together. Hence the adjective "composite" because that's what they are. They totally differ from your granite counters, those are a big pieces of solid natural stone. So a composite sink never needs sealing (the resin in it makes it impermeable for life), and is more sensitive to high heat (the plastic resin being its weak spot).

2-"Granite" sinks are a new product in the marketplace, only several years old, so it doesn't have the decades-old record that the other sinks have. How will it look in 10 years? Anybody's guess. It may well end up like the "marbled" vanity sinks (acrylic), that will crack where the hot water hits it, typically around the drain area.

3-I've seen 30+ y.o. stainless steel sinks in great shape, which is easy to accomplish with some maintenance. Buy the sink with the BRUSHED finish, not the satin or polished finishes. Then, whenever it scratches, in a few years, get a coarse sandpaper and slightly sand it along the brushed lines to hide scratches that go "against the grain". There are kits for that, but sandpaper and Comet powder do the same for less.

4-Porcelain over cast iron sinks look great at first, but once the surface wears out with cleaning, they're gone. I've seen people "refinish" them as you would an old bathtub, but the results vary. It will never look as good as new again.

Because of the above, stainless steel sinks dominate the marketplace, with over 85% market share of new/remodeled homes.

Notice I didn't say what sink I have, because I am not in love with it. This is just a statement of facts, not emotions, since no sink is perfect and all have their advantages and disadvantages.

I did not like the "free" sink that the contractor offered. I purchased a composite granite sink from Lowes also . The first thing that I noticed was how light it was. I chose the SLATE color to coordinate with the blue black granite counter top . I have had no problems with it. I called the company about the possibility of it cracking. They said that should not happen. "Just don't take a 20 pound turkeyb and drop it from the ceiling!" JIM

I have had a black composite sink for 3 years now -- Blanco. I LOVE it! It is nice and deep-- I can put a pasta pot in there and not see it until I am standing over the sink. and I can't see any stains though you can see every crumb until you wash it away..

The composite sinks are as others have said, not "granite" and do not need any special care. They take probably the most abuse of everything out there, and they are quiet. We've had a huge single from Blanco for a few years and the most we ever have to do is give is a quick cleaning with whatever dish soap is handy and a brush or scrubbie and it looks like new. They are standard colors and you can match or contrast depending on the look you are going for. I'll have a hard time ever owning anything else.

We installed a black Franke composite sink and it looked grey and dry in a matter of a few months. Love the size of the sink and how it looks with our granite counters, but the constant oiling to keep it looking new is really annoying! Not sure I would do this again as it's very frustrating to keep it looking good. I also wonder how sanitary the mineral oil makes the sink surface, which is what customer service recommended. No perfect sinks out there, but I would go with high grade stainless steel next time.

I have updated my kitchen including black granite composite sinks. Of ALL the new items installed, my sink is my favorite. Never stains, a quick wipe with just a paper towel and it is always spotless. Just love it!

I noticed that Costco also has the Franke granite composite kitchen sinks for sale and their add says no staining becuase of how its made. One thing about costco is that if you buy most things from them and keep your membership up they guarentee the product for ever.....

I have a granite composite sink and it looked great for about a month. It stains very easily.

I have little white scratches on my dark brown granite composite sink. How do I get rid of them? I am afraid that the dark brown color is just a paint and if I buff it, the scratches will get worse. I wonder if concrete stain would hide them?

Why did you replace the cast iron with the stainless steel? I have the same dilemma. I'm installing a granite countertop and they're recommending I replace my old cast iron with stainless steel. My cast iron is about 20 years old but looks fine. It is an undermount. Should I keep it or replace it? I could also replace it with another cast iron sink.
