May void warranty. Quartz is a synthetic w resins that won't handle the heat. I don't know the specs for Ceasarstone, but be careful.

"Natural Quartz" is man made.

Granite is natural stone

Quartzite is natural stone.

Pro ranges REQUIRE a backguard. You will scorch the quartz and void the warranty on the range and the quartz. Plus violate the fire code for combustible clearances.

There are a number of threads on this forum from people who have installed Quartz behind a range or cooktop, but have not installed the range's backguard (an extra) with it. They got scorch marks or cracks. The Quartz warranties of all the manufacturers (though no one looks at those warranties) say it cannot be installed directly against a heat source. You have two choices: no Quartz behind the range/cooktop, or, Quartz behind the range/cooktop with a backguard.

Here are links to a couple of those threads:

Thanks so much. This really helps. Lots of confusing information out there.

" You have two choices: no Quartz behind the range/cooktop, or, Quartz behind the range/cooktop with a backguard."

No, there is a third choice. Install the appliance with a 12" clearance between the back of the appliance and the estone. And let's stop blaming manufacturers for designer/homeowner/installer error.

Joseph, with the third choice as you put it, what would the hood exhaust set up be? I imagine you’d have to install some kind of block behind the hood to push it forward 12” so as to cover fully the range’s burners. Whatever that block is would have to be non-combustible. And then the duct from the hood into the wall to the outside might be problematic. I expect an island hood with a chimney-style duct could be installed over the range that is pushed forward 12” would work, with the duct going up through the kitchen ceiling. I wonder if a homeowner would be able to do that with her existing home construction. That’s a lot of configuring so that the Quartz can be installed behind the range with the 12” clearance ”third choice”.

Shannon, you can order custom hoods at any depth you want. If someone is spending money on a pro range, they should also be budgeting for the ventilation to go with it.

It’s simple. Look at the installation instructions for the range. It will tell you the requirements. For my Blue Star if you are not using a back guard the range has to be 6 inches from back of range to combustible surface or the wall has to be constructed from non combustible heat resistant material that extends 6 inches below the top surface of the range.

“you can order custom hoods at any depth you want.”

Chispa, a standard non-pro range is about 24” deep front to back; a pro range is deeper than that. Add Joseph’s 12” to that and the hood would have to be 36” deep front to back. Yes, you can custom order anything, but how would a hood that measures 36“ front to back fit in a home kitchen? Please explain. I mentioned an island hood ducted through the ceiling but that may not be how the home is constructed for ductwork and beams. This 12” clearance issue involves a lot more than “If someone is spending money on a pro range, they should also be budgeting for the ventilation to go with it”.

With this 12” clearance option, what do you do about base cabinets and counters surrounding the range? Are counters going to be increased to 36” deep also? Or, by how much can the range protrude from the surrounding base cabinetry? People sometimes get base cabinets that are deeper than the standard 24” depth. But those are 3-6” deeper than standard, not 12” deeper. And then, what happens to upper cabinetry above base cabinets that are that deep? And, are the dishwasher and fridge also pulled that far from the wall in the cabinetry run? Chispa or Joseph, please explain how a kitchen can be set up and designed if the range must be pushed away from the Quartz backsplash by 12“.

As I said earlier, one can get a range backguard, or alternatively not get Quartz behind the range. Or there is the 12” clearance option, but I don’t know how a kitchen can be designed around that.

Shannon_W:

I never said designing to allow a quartz backsplash would be practical or easy. My point is that it is unfair to blame engineered stone failure for the mistakes of designers. You can put wallpaper behind a range; just make sure you've got your clearances.
