What was there before, can you show us? To replace with tile pieces isn't really sounding like a good design solution, it will look like you fixed a mistake...

What is going to be covering the raw wood edges parallel to cooktop on both sides? The 3 strips…

Placing Taj Mahal on the front of your hood doesn't seem like a great idea. It really doesn't go with your very traditional cabinets. Plugging those holes will just highlight the mistake. I would stop the project, rethink every detail and what you really want to accomplish with this update.

I have no idea what the plan was but from the description a bad idea all the way around . Can you post a pic from before this was started/

Not sure what we are voting on. I see two options: replace the backsplash or replace the hood/cabinet. Patching is a terrible idea.

Hopefully your contractor knows what they are doing - you are mounting a heavy piece of material to the front of a cabinet? I hope not - not sure it would hold it since it's not what it was designed for.

I would pull the whole hood out so proper framing and support can be built.

As for those patches - I would cut the stone across and then fill in the one piece instead of 2 patches since they will never look right. Not sure how good the one longer piece would be but it might be better than the 2. Not sure how easy that will be sine it is all installed.

Good luck!

"I just ruined my kitchen stovetop backsplash!"

Yup, you did. And are adding on more ruination. You have a future crash and burn. Big big crash. And big burn. You will be lucky to not be seriously injured. The entire thing needs to be redone with someone who knows how to design and engineer. You might as well plan on replacing the backsplash, and replacing the hood both. Never will be the same.

Trim them out in fine detail wood trim like they are tiny tchotchke niches and put something in them :)

What was your original thought in having those two sections cut out? Was there a design reason that you were thinking.?

Are you really putting a piece of stone on a piece of wood hanging above your head and back? How is this engineered?

I'm not understanding why the cutouts needed to happen in the first place. If they were to accommodate brackets for the hood, why couldn't they drill right into the stone? As for placing Taj Mahal on the front of the hood cabinet, I hope the thickness is thinner than the countertop thickness. Usually, anytime you're using cladding on a vertical surface, the cladding is roughly 1/4" thick. This is why some quartz manufacturers have two thicknesses available for their product: the thicker ones are for horizontal applications like counter tops, and the thinner ones are for vertical surfaces like slab front cabinets/doors.

Make sure your fabricator is using a thinner slab for the hood.

Even a thinner piece of stone will not work for this. Because that hood WAS NOT DESIGNED TO ACCEPT THE WEIGHT of any stone.

Thank you all for your input. It’s definitely a Mac Guyver situation. Thank you for the safety concerns. I made a last minute decision to cut out wood pieces, that’s where the issue is. We are carefully finding pieces that match and plugging. It’s awful.

Yikes!

Can we see a photo taken from further back to see the bigger picture of how the upper cabinets and original hood are installed.

I don't know what to say about sticking stone to the hood exterior--just be careful with that concept.

If you do a strip of replacement stone alllllll the way across from hole to hole, it might look okay. You'd do a nice edge on the bottom of it, not quite as froufrou as an ogee but fancier than just a pencil edge (your cabinets will support some fanciness). You can add a shallow shelf there if it helps.

Or, get a stainless steel sheet to go across the spot, possibly with a stainless shelf at the base of the metal section. (Use additional metal to cover the sawn off pieces of cabinet too.) Like the top part of this (ignore everything below the shelf which would be your stone), but shallower:

Stone is heavy and given the high position of the hood, that just seems unnecessarily risky. I would seriously rethink Mac Gyvuring with a heavy piece of stone. What happens when the stone becomes detashed from the hood? I've seen too many photos of countertop failures in this group to wonder IF the stone will eventually fail. And I've heard way to many ER horror stories of the unexpected. I wouldn't risk something with the potential to be lethal in the case of failure. I'd plan for it to fail and make plans accordingly. At least that minimizes the risk. Maybe start with searching for a hood that is designed to accept a stone facade (assuming that exists). Or at least have an appropriate surface reviewed by a structural engineer and manufactured to spec.

Beautiful stone. But safety aside, I don’t think that piece of TM will enhance your kitchen. Your cabinets are very nice, traditional and look in good shape. You already have TM on backsplash and countertop — let those shine!

Check out this post on Houzz from 9 years ago from someone who created a marble clad hood. https://www.houzz.com/discussions/2687983/have-you-ever-seen-a-marble-rangehood . It involved making a steel cage that was bolted into joists in the ceiling. This is a no joke kind of project that you don't want to Mac Guyver.

Aside from your guillotine hood, I don't think the backsplash situation is as horrific as others are making it out to be. Put a block of wood in each cut out and stain it to match your cabinets. I think it will be fine.

I saw that thread earlier when researching this topic and I was so impressed with the supports and the work everyone did to make sure that the marble could be installed. I was hoping that the OP would come back and post finished pictures but couldn't find them.

It is a fascinating read.

Have the fabricator cut 2 pieces in a shape you like and have them overlay on the TM in a mirror image design. Kind of like side way corbels, but made of stone to cover the openings.

At this point, I'd recommend a re-think on the floating stone hood and contact a good metal fabricator to cover the hood with stainless, and cover the holes and the raw exposed wood at the same time - create a cohesive, built in look with a material to match your cooktop. Create a shelf as Fori shows and have salt / pepper stored there. Don't add any more TM.

It looks like there was room for a hood that was 6" wider than the cooktop but then the hood was narrowed. That's too bad - as the additional space helps with steam, grease and odor capture.

I showed my boss a picture of this and he just shook his head. I asked if we would ever... I couldn't even finish my sentence - Absolutely not! This will fail and there will be collateral damage. He said the hood must be completely removed and you start from scratch.

Please rethink this - I would hate to hear of someone getting hurt.

Something like this would need to start with steel structure tied into the wall framing. And the stone would have to rest in a metal frame. This sort of structure would have to secure enough to support an adult hanging from it, and the stone would have to be set in such a way that it could not fall out by becoming unglued.

Perhaps it isn’t too late to salvage what is underneath. What does the hood look like under the styrofoam?

Thank you all for your answers! We figured it out a solution.

Why would you need a metal frame? Stone is not that heavy, that piece will be less than 100 lbs. Certainly the OP wants to ensure the stone is mounted to the plywood properly and that the hood is properly mounted to the studs, but if everything is secured properly that wood could hold an entire slab.

@User - None of your post has anything to do with metal vs. wood. It is much more difficult to get stone to adhere to metal than to wood and any method that could be used to safely achieve that would be easier in plywood.

As for your theory of movement of mechanically bonded plywood and stone... It doesn't work that way. There isn't actually going to be a different rate of movement on the face of the plywood because that is what adhesive bonding prevents, which is how/why plywood works.

Really bad idea, sorry to say.

Why? Because your cabinetry in what is probably a hi/lo perimeter, of very European style and finishes ala year 2000, was not, is not suited to the idea of a sleek stone hood which is NOT done the way you were attempting to do it. You don't just slap stone, on a wood box.

When you take ideas out of the context in which they should live? An incompatible look, to begin ? This the resulting horror.

If the hood isn't deserving a trash can? Get an excellent trim/stain guy and fix it and put it back up and have the stone fabricator make sleek/simple corbels that blend the concept.

If I find out there's a Travertine floor in that kitchen?? I won't be shocked : )

Assuming the brass supports are staying, so how about finding two pieces of brass to fill the spaces?

etsy has loads...

Just found this site. Contact them, show them the photos and see if custom pieces could be made...maybe with raised edges?

OP: You wrote 2 days ago that you came up with a solution. Can you share what your solution is?
