Seperate a granite tile backsplash from an existing countertop

If you are talking about a gap caused by the height of the stove, You can lower the height of the stove by adjusting the threaded leg posts on the bottom of the stove. A more difficult fix would be in raise the height of the countertop and cabinets by shimming the bottom of the cabinets.


If your gap is not a height issue, then you can experiment with some type of trim around the stove itself. Local granite dealers has an assortment of trims for issues like this.


I was able to find a number of trims for a back gap on my granite countertops and backsplash from my local European Marble and Granite.

You should just be able to set the cooktop in after you attach the downdraft, usually there are tabs on the downdraft that clamp on to the granite cutout. There is probably a closed-cell foam strip that runs under the lip of the cooktop, I would just make sure it seals to the granite properly (no gaps) and put a couple dabs of silicone in between the lip of the cooktop and the granite. Usually the cooktop is heavy enough that the silicone will keep it from moving around.

From my experience, most cooktop manufacturers give cutout dimensions that almost always need modifications to get the screws or nuts on the stove to fit the cutout. Have your granite fabricator come enlarge the opening by grinding specifically where there is interference. They should be able to tent off your granite and use a vacuum to minimize dust.

They suggested a dryer because they thought the stone had absorbed a liquid and was causing the stone to darken. This is common on unsealed granite. If you put a sealer on the counter tops however, whatever it is you see there will remain under the seal. I would ask the installer to come out and take a look at it. If they are unwilling, the Home Depot has a cleaning kit sold in the kitchen counters area of the store made by a company you can call and they will ask questions about the problem and provide advice on how to fix it. They are extremely helpful with free suggestions as well as stuff you may be able to purchase to fix the problems. In any case, granite is sensitive stuff and while it is physically durable it seems to be extremely sensitive to stain and etching and learning about proper care, cleaning, and dos and dont's will save a lot of heart ache and time for you down the road. (For instance oil absorbing into the stone is a several day ordeal to fix). Good luck with getting the results you want. If you did find a specific solution please share it here.

Put a bead of clear sylicone caulking around the cutout , then set the cooktop in place .

yes you need a seperate line for the cooktop. whoever hooked your oven and cooktop up in the first place should have never hooked them to the same line to begin with. you are lucky you never had issues.

take the whole cooktop out there should be screws around the base you take them out, seperate the bottom from the glass you should be able to get to the element to check if it is bad by ohming it out

I can't imagine directing the downdraft vent back up to a traditional hood type system. Why bother, just don't use the downdraft or get a cooktop without a down draft and save money.

In granite, yes for any cooktop as long as someone can cut the correct size hole. Cooktops must be installed so the top is just about flush with the countertop. They all come with a template for cutting the right size hole in the countertop.

two part epoxy specially made for granite.
to take just the backsplsh, you need a dimond saw to cut it. polish it. no other way I know.

suspect your contractor didn't allow for the tiled floor. the range legs are usually adjustable up and down. have you checked this?
