I have a Corian coved backsplash (with a coved side too) in our main bathroom and a loose one in the kitchen. Take a picture of the problem and I can tell you whether it was done correctly. Our fabricators were Corian specialists. Did you check to make sure he was a certified Corian fabricator?

I just looked up the Rosemary, I really like it.

Thank you for the input. I'm new at this and do not know how to post photos, but I will try to figure it out. The fabricators are certified to do Corian, but their other work has been sloppy as well. I used them 3 years ago to do my kitchen and everything was perfect, but this time we're having a lot of problems.

This is a new pattern, and does have some movement, but I would think they would have let me know if it wouldn't work out. I'll work on getting those photos loaded up. Thanks again!

I think I figured out how to post the photos. There should be 4 photos, so can you let me know if it didn't work? Thank You!!

Wow, you're right, that is very distracting. Because of the pattern it really looks like a giant shmear of caulk or something.

Unfortunately I don't know what to tell you to do about it, but I think it's unacceptable the way it is. A loose backsplash might not be the look you were going for but I think it would be much better than what's there.

To me, it's sort of like I wrote in my previous post.

I think it's a directional or movement pattern that would have been best served with a simple butt joint.

I think it's your third photo, if you like the way the vertical seam in the corner of the backsplash looks, you can have them redo the entire backsplash with a simple butt joint like that.

Oh, holy bad Corian job, Batman! That is awful. I wouldn't hire them to make a cutting board after seeing that. There is no excuse for a job done that poorly. I would call Corian (DuPont) and ask them about coving that particular type of Corian. There should be some kind of warning with that design that either warns fabricators not to cove it OR gives them special instructions on how to work with it.

Boo Hoo!! I really wanted the cove. I'm not sure if I should refuse to pay for it and see if someone else can do it, or if it's just not do-able. I will take your advice(susanelewis) and check with Dupont. I think I should have been warned about this by the fabricator.

I don't blame you about the cove. I have it in my main bathroom (Oceanic) and it is really nice and easy to clean. Check with DuPont first and then you will know whether it was a bad job or an impossible project. Either way,you are right...you should have been warned. AND any reputable business person would never have delivered a POC like that to you in the first place.

cove or not, that job looks bad.

I checked with Corian, and they do not recommend a cove for the Private Collection, which Rosemary is a part of. (that would have been nice to know sooner) Everything matches so perfectly in my new bathroom, so I would hate to have to change the countertop, so I may have to go with the loose backsplash. I'll look at what is available and get back to the fabricator. Do the loose backsplashes and sidesplahes look ok? I looked at the corner seam (as per mongoct), and it doesn't look bad, I just hope it looks good all over. Susanelewis, how does your loose backsplash look? Are you happy with it?

I have Magna Platinum in my kitchen that has the loose backsplash. I wanted the cove but it was price prohibitive at the time. It looks very nice as they used a very fine clear sealant/caulk. I am happy with it and don't miss the cove. In fact, we hope to add a tile backsplash and we're going to leave the Corian backsplash.

Shame on your fabricator for not advising you against a cove...

I'm Back! The fabricator will re-do the top with a loose backsplash, and it should look fine. Does anyone have a recommendation for a simple edge that would look nice? The vanity is only 27" and the bathroom is not ornate in any way. I had the beveled edge, but without the cove I'm not sure how it will look and I really don't want to make a mistake!

Beveled edge? Is that the standard edge or the bullnose?

I have the standard edge on my Corian but I equally like the bullnose (upgrade). I'm glad I didnt get the ogee...that is so last century! (lol)

It seems that there are 4 standard edges.
The single roundover (rounded on top only)
The double roundover (rounded on top and bottom)
The single bevel (notched on top only)
The double bevel (notched on top and bottom)

The ogee is definitely not my style. I'm probably over-analyzing this at this point, but I'm a little nervous after the last disaster. I'll probably go with the bevel again, I just thought I'd put it out there....

One last question. My fabricator is getting ready to redo my countertop with the loose backsplash and sidesplash. He said the thickness will be 1/2 inch and says that is the standard. Does that seem small? Unfortunately, I have lost trust in him. Susanelewis, I know you have the loose backsplash, is that about what yours is? Once again, I really appreciate all of the help I have gotten in this forum.

Yes, that is standard and the same size as my loose backsplash in the kitchen. Just make sure he uses clear silicone at the joint so that it is virtually invisible. You should not see a caulked joint.

Thank you so much for your help. I'll let you know how it comes out.

I am sorry to post this late. I joined as a member because a customer has the same concern, and directed me to this post.

As stated in earlier posts, Rosemary is part of the Private Collection of Corian products. This series is primarily defined by the directional patterns, or "movement", as it is known in the trade.

When fabricating with this material and there are no end walls, there is usually no problem. The right-left pattern flow on the deck continues as a left-right pattern in the backsplash.

However, when you have end walls, and desire end splashes, you are faced with a dilemma (just like you would have with natural stone tops, or wood grain tops, or similar). You can either match the grain of the splashes- where the side splashes would run front to back, flowing naturally into the right to left flow of the backsplash, or you can match the deck, wherein the end splashes are "waterfall" on the ends, flowing top to bottom, but forcing a direction change at the splash, where top to bottom end splashes meet right to left backsplash.

Having a coved splash does not change the dilemma, but it adds a few other elements. The coved inlay amplifies any visual difference. Your eyes become more 'picky" about any deviations in look, because it is so much more smooth a transition. This is why a coved splash in a Private Collection top is something of a dilemma.

And yes, you absolutely should have been made aware of this.

the samples are never true to what the countertop ends up being. I ordered Thyme and it is loaded with blue streaks that look like chalk and placed badly I might add. Dupont is very deceiving about this product

These are close-up pictures of the Corian Witch Hazel tile cove in my recent bathroom makeover. This is very nice if I do say so myself, but the fabricator has to make sure he makes the cove from the piece cut off the sheet in sequence. A thermoformed cove will be perfect.

Dupont, Corian's manufacturer, is constantly inculcating fabricators to set realistic expectations for consumers; it pervades their literature and instructions. If consumers are disappointed, it is a fabricator sales problem, not DuPont's and not technique. Solid surface with lots of movement must be approved by viewing at least a half sheet, not a 2"x2" or 4"x4" sample.
