Get real stone then you can do this but not with quartz ever IMO.BTW post pics

Wall hoods have backs--no need for an island hood to get 4 sides of containment.

(Extending beyond the stove is a good thing--you catch more fumes.)

(Be sure your backsplash won't be damaged by heat. Follow stove and backsplash manufacturer's guidelines. Not all stoves will damage a solid surface backsplash. Many will, depending on if they're high BTU or just have an oven venting in the rear.)

"No quartz or solid surface behind a range. The heat will damage it. Brown scorch marks."

No blanket statements please. Your backsplash is dictated by the appliance manufacturer's installation instructions.

I saw an episode of This Old House a while back during which they installed a large vintage cast iron (I think) plate as a backguard. It was just beautiful.

I don't remember which season it was, sorry.

Can I do a metal splash behind the stove top and surround it with solid surface stone or quartz. There will be no cabinets on this wall. We wanted this to be the feature wall of the kitchen. The other walls will be solid surface.

Will you be using that particular stove? It can have just about any kind of backsplash you want behind it safely because of the built-in backguard thing. A solid surface backsplash would be nice!

No we have a Samsung flex dual fuel being installed.
