Have your fabricator contact Chemcore please. Staron makes excellent integrated solid surface sinks. DuPont, Corian's manufacturer, only sells to authorized fabricators, but it's worth a shot.

I am surprised the fabricator does not know about these, they are right on the Corian website:

https://www.corian.com/-sinks-lavs-

Please note that they only come in four colors and they do not guarantee it will be an exact color match to the same color name in sheet material.

If you want to have the Corian integrated sink match the countertop Corian in one of those other colors or patterns, the fabricator would have to make it. My fabricator made me the sink since I wanted it to match the countertop material

(it also has a cove around the back and sides because we tiled it in.

It concerns me that your fabricator did not provide appropriate guidance/information. If he/she does not know where to find integrated sinks what makes you think they know how to integrate the sink? Do they have enough experience to manage the issues that may arise?

Lack of knowledge in someone's specific area of expertise is enough to make me run.

Do not use this fabricator!

I used an integrated corian sink/counter in a bathroom of my previous house. I looked up the top Corian guy in that area and used him for that part of the project. He supplied all materials and labor for that sink/counter. Perfect color match and no visible seams.

Some after-market vanity sinks are thermoformed from genuine Corian sheets. Thermoforming alters the color slightly, but fabricating a bevel, instead of a rounded sink edge profile, recasts the light and fools the eye somewhat.

I'm having a hard time finding fabricators that specialize in Corian. I can find all kinds of fabricators for other materials but I'm not finding a lot of options for solid surface. I'm in LA so there must be lots of people who can do the job but I don't know where they are all hiding.

I hear the concerns about this fabricator. I'm a little concerned myself but he seems to have a lot of happy customers. I think he has enough business doing the easy stuff that he doesn't bother with the hard stuff. Originally I wanted a very unique design and he referred me to another company that does custom work (but they are far away).

He told me to look at websites for Corian, Keystone and Gemstone. However, I couldn't find the integrated sinks on these websites. They do not make it easy! This is what I found at Corian, and I don't think any of these sinks are integrated: https://www.corian.com/-bathroom-basins-

The problem may be that I am seeing integrated sinks, but to me, they don't look like something that can be integrated into a counter. Even the Corian link posted above which seems like it is for integrated sinks, those sinks don't look like they can be integrated to me. I guess I'm just looking for web pages that say "INTEGRATED SINKS HERE!" but can't find that.

Even Joseph's Chemcore suggestion didn't help. They have all kinds of sinks but I found no integrated solid surface sinks.

The sinks that are on the Corian page are made to be integrated, bonded right to the material. This sink that Chispa shows from her bathroom is one of those sinks.

It shows them integrated in the slideshow at the top of that page.

Also click on "More Information" : it says "They can be seamed to sheet colors with the same sheet color name for a continuous appearance"

"Even Joseph's Chemcore suggestion didn't help. They have all kinds of sinks but I found no integrated solid surface sinks."

Go to "Sinks" then click on "Lugano" please.

Try Karran also please. Excellent sinks.

There are dozens of kitchen shops and big box stores that sell Corian in LA county. The people who sell the countertops have fabricators that they work with. Go to the Corian website to find stores near you. Visit a couple of stores. Pick your countertop and sink and have them coordinate the fabrication and installation.

Years ago, the wife of Andy Graves of Olive Mill asked us fabricators to mail her child a postcard as a school assignment. They got a great response; myself included. Fun memories.

@uscpsycho, that white corian counter and sink in the bathroom was in LA, in our previous house. I'll go look through my project binders to see if I still have the information.

Found the invoice! The company was Valley Counter Fitters in Chatsworth. This was back in 2017, so not sure if they are still around.

@chispa, is the sink pictured in your post oval or round? Do you remember size and Corian color? Thanks!

@MinnesotaMary, the sink was in my previous house, It was oval. I am away from home right now, so I can't look at the file for any other info. I'll take a look when I get home next week.

@chispa, thanks!

@MinnesotaMary, back home and pulled out the file for that bathroom. The color of the Corian sink and counter was Glacier White. Unfortunately there was no size listed for the sink on the invoice, but I'm sure it was one of their standard basic offerings.

@chispa, thank you! That is a happy coincidence; we selected Glacier White on Friday. Great minds!
