I've heard of hoods covered in Corian but not in quartz. You wouldn't want someone to die if it fell down, which would happen if it occurred at the wrong time and place. Quartz needs a lot of support and isn't designed for free-floating vertical installations. One slab of quartz alone can weigh over half of a ton. You're looking at about 25 pounds per square foot to break it down for a 3 cm slab.

Why is the hood over the sink?

Engineered stone is available in 12mm (1/4") thickness. I just saw a countertop in a recreational vehicle that was 1/4" with a mitered edge, probably to keep weight down. 12mm is perfectly fine in a vertical application, as are other thicknesses.

At what stage is the project? Is it the hood Itself the issue or the wall support structure needed to support it?

Quartz is not heat-proof. We have seen plenty of posts here of people with Quartz too close to the heat source (the range/cooktop) with scorch marks and/or cracks. Also, the Quartz manufacturers put an exclusion in their warranties for damage to the Quartz from being too close to a heat source. There are so many other hood materials - you can go as high-end crazy as you want - that will be more suitable for a hood enclosure. Check out the Modern-aire website for inspiration photos.

Thank you!!

The sink is in the island in front of the range...

Quartz countertops are stain, scratch, heat, and chip resistant. They work in commercial or residential spaces. They are also resistant to moisture, so they’re perfect for the kitchen, bathroom, and laundry room.

Don’t swallow the koolaid by repeating the sales manual word for word. 🙄 Heat resistant just means they don’t light on fire. They bubble and turn brown with heat just fine. You’re also talking steel framing, plus 15K worth of stone at a minimum.

Quartz countertops discolor when they come in direct contact with high heat sources. Resistant is just as the word describes. This is also why they cant be used outdoors in sunlight because they will discolor. I hope the person selling you on this isn't telling you quartz is indestructable, because it is. I urge you to look up quartz images damaged from heat.

And heat isnt the only thing that can damage a quartz counter using the wrong cleaners can as well.

Quartz is great but please don't be sold on the falsehood that it is the end all. It isn't.

What do you think of porcelain slabs? I’ve been cautioned it could easily chip... I worry about around the edge of an undercount sink.

You should be working with a kitchen designer for a 140K design this ambitious. Why haven’t they explained all of this to you?

It was my kitchen designer who cautioned me about the porcelain. She says it a new unproven product. I was just asking for other opinions.

"Quartz countertops are stain, scratch, heat, and chip resistant."

Sharon McBride - please refer to the photos I posted in this thread for the "heat resistance". Nope.

On HGTV, a new trend is a metal vent liner inside a wood cover matching the upper cabinets.

Porcelain isn't a new unproven product - it's been in use for a very long time, and even the countertop slabs have been around quite a while at this point (I mean, not compared to real stone, but they're not that much newer then quartz). They can chip. So can quartz. So can real stone. If they do chip, my understanding is that they're nearly impossible to repair, where as quartz and real stone have a bit more repairability.

If you want stone on your backsplash and hood, though, I think your reasonable choices are porcelain or real stone. I would not use quartz for those applications because of the heat risk.

Another option would be to do a very, very quiet white quartz (not stone look, no veining, something like Pental Cascade White) and then use a stone-look porcelain for the backsplash and hood.

I’ve got my heart set on Daltile One Quartz Calacatta Carina. We’re going to waterfall it on the island and run it up the backsplash. I think I’ll do a drywall hood vent. I appreciate all the feedback!! Thanks all!

A lot of stainless steel hoods are very attractive and a lot of hoods are hidden behind faux cabinet fronts that are equally attractive. Would not risk creating a potential hazard. Would reconsider the height of the backsplash overall rather than put heavy stone over a range hood.

We’re building a mountain modern timber home...

I think your plan of doing a drywall hood instead is a better visual option than the quartz since you are also doing an island waterfall with it, too. Too much of a good thing can be too much!

One other thing, if you've been around on Houzz for years like some of us, you learn by the quartz problems posted that this product has been marketed in such a way to make the end user believe that it will wear perfect and basically can take anything. Well, it doesn't always and it seems that the warranties have a lot of loopholes that favor the manufacturer when problems do arise. So just go into this with your eyes wide open knowing that you may have some issues with it but then again it may wear perfectly for you. Just like any product.

I did come across this 4 yr old Houzz post that refers to Daltile quartz. You may glean some info from it as far as testing the quartz before you purchase, if that is a concern to you.

The brown scorching of the quartz backsplash will tie in nicely with the brown woods used in the home. Probably not the design integration you have in mind though. Plus the issue of the mismatched veining of the island seams will drive you around the bend if you don’t love mismatched seams.

Quartz is simply not going to fill the role you think it will here. Someone is SELLING you here, and you’re swallowing it whole. Is your designer sourcing your products and charging a commission on product purchases? That’s normal, but it can lead to a conflict of interest when financial gains from recommended products interfere with recommending the best product for a client.

No, my designer is not getting any commission from my purchases.

Wow live_wire_oak you sound like a real Dick. She’s just looking for opinions.

Wow, @yseth005. Go look in the mirror. Only a ”Dick” would resurrect a two year old thread, to offer nothing, yet call out a long time contributor to this site, and its precursor, the GardenWeb. FYI, @User is a Pro, and knows what she’s talking about.

Oh, and, offering her opinions, is exactly what LWO did…her educated opinions.

Seemed the over the top to me. But point taken, my comment wasn’t helpful or nice either. Thank you the course correction, I will delete my previous comment.

Looks like I can’t delete it, or at least not from my phone. I re-read the comments again. Definitely over the top. Very condescending to the person just asking for feedback. Not what you would expect from a “Pro”.

@Sharon McBride Since someone resurrected your post, what did you wind up doing in your kitchen? Personally , I would love to see a picture
