I still prefer stainless, under mounted.

"gross mold in the silicone grout lines where sink meets the counter material"

No excuse for that. It's a reveal and cleaning issue: )

Corners......a radius issue CAN be a non issue and there is a reason for the sprayer in your faucet.

Just enough- still crisp - no goo

You can’t argue with the clean look of an integrated sink, but the issues you have with stainless steel can be summed up as cheap sink with a bad installation. Loud means you have a thin sink with no baffling; mold in the seam means it was installed badly, probably without a harness; lacking slope means bad design on the sink, same with the corners.

An integrated Corian sink shouldn’t have installation issues, but it can have design issues so be clear about what you want, and choose a sink with the right slope snd corners. The most common complaint about Corian sinks is that they stain, and over time you can get abrasions that collect crap. There's nothing you can do about microabrasions on a day-to-day basis, but you can have Corian refinished (sanded) and it will be like new. Until it abrades again and you refinish it again. For the stains, DuPont recommends a solution of bleach and water.

@Joseph Corlett, LLC thinks Corian sinks are great, so that’s a hige thumbs up as he is a pro. For my money (literally, I bought one) there is only one lifetime sink, and that is a high quality, well designed, properly installed (Hercules Universal Sink Harness) stainless steel sink. For your deliberations use the search box to learn more about both types of sink. Whatever you choose, I hope you love it.

So something happens to the sink you have to replace the counter makes no sense to me and I think in a MCM home that would never hve been there . Stainless sinks IMO are always the best choice and as for the rest of the issues those are all able to be dealt with with the right sink. I didlike plastic counters in a space where hot pots and hot liquids are the norm

Love my Solid Surface sink and counters. They are close to 20 years old and still look great. My sink is an off white as I recall the designer saying white was harder to keep clean. We are on a well with hard, rusty water. I have wished at times that we went true white as it would look cleaner. only babying we do is running water while draining a boiling water pot into the sink.

I have an integrated Corian sink in one bathroom which is fine, but different situation.

You can still buy stainless steel sinks that are very rounded and not flat on the bottom. Look at Elkay Lustertone sinks.

Have the best of both worlds, an integrated stainless steel sink. No silicone, no reveal, no crud, nothing easier to clean or maintain. Karran 540:

I have corian counters and an undermount stainless steel sink. Maybe the gross mold issue has something to do with poor sink installation. I don't have that issue at all with mine. Noise, corners, and slope can all be corrected with the right sink. I don't encounter those problems. I have a Franke sink, not sure of the model. I think stainless would look better with MCM. Integrated corian sinks feel very 80s 90s to me.

Had an integrated Corian sink for 19 years and loved it, still looks great. Just moved into a house with an under mount SS sink and I very much am not a fan (flat bottom, hard to wash anything down the drain, water splashes out, looks scratched).

Joseph Corlett, LLC , The Karran 540 looks intriguing to me, thanks for sharing. I went to their site and I don't quite understand how what makes it seamless. Doesn't it connected to the corian countertops in the same way that any other undermount sink would? Can you explain to me how it becomes seamless?

I also wish they made off-set drains on either the left or the right so that I could have a pull out trash underneath. Maybe they offer this and I just haven't seen it yet. I was highly considering a custom-made Havens or Rachiele SS sink, so they could at least address my slope concern by increasing the slope for me. Compared to the Karran, not only can they do offset drains, but they both offer 314 ss instead of 304 ss, 7 "or 8" bowl depth instead of 9", and a 16 gauge instead of 18 gauge. So I guess you could say I'm still considering Havens and Rachiele as options if I decide against the integrated corain sink.

"Isn't it connected to the Corian countertops in the same way that any other undermount sink would be?"

No. While many sinks are clipped, blocked, or strapped in place the Karran 540 is glued in place. The sink flange is plastic and adhered to the bottom of the Corian.

Hello again Joseph -- I know I want the "best of both worlds" -- having decided that, I can't find anyone who will do the work. Was planning on getting the corian from HD, but their installers don't do shower walls (my first question to them) and now say that while "integrating the 540 IS possible, it's not something we can do." Apparently they only do kitchen countertops - they'll do a corian sink, but that's not really my first choice. I've used your isfa search to find someone but nearest result is 160 miles away. My kitchen designer from my contractor's supplier managed to get me a countertop quote and then a week later said the installer doesn't do Corian anymore and she'd try to find another installer but so far, no luck. Frustrating.

I agree it IS very frustrating. Who is to blame? The consumer, actually.

Kitchen design in general! Even Corian/Dupont.

The real steep "slide" out of favor for a perfectly great surface began when quartz supplanted the swirly yogurt slabs of granite........and south went the suppliers and those who'd install.

It was further pushed by the concept of the gigantic "gathering island" in the kitchen, meaning the material would have needed a seam. Now? You CAN get extra wide sheets of Corian in 1/4 and 1/2 thickness 48 and 60" wide and WHERE? "consult the distributor list.", and they are the basic colors, not every color. But who cares? When you want a perfectly plain in a sort of this, sort of that WHITE? Corian was the perfectly plain solution!

We have ONE shop left for the original Dupont solid surface , locally. It's just absurd. For that I blame Corian - Certification requirements , markets they simply have abandoned? Who knows.

Although Dupont owned both the Corian AND Zodiaq Quartz, rebranding the name to Corian Quartz shows you where their effort went........And they are still at it.

When I get around to redoing my kitchen counter / sink I'm replacing the old SS countertop with... a new SS counter and sink. This one has lasted 80 years and is damn near bullet proof. No need to seal, or worry about hot pans, etc. The island may be something else, but the "L" from the stove to the sink is absolutely going to be SS.
