Quartz support on an island

    We used metal brackets like this for our 15" quartzite overhang. I'm assuming your is 24" (2' feet?) not 10 inches like stated above.

      Up to a 10" overhang, no support should be needed. (Industry standard). If you would like the added security and piece of mind that may come with extra support, and "L" bracket or corbel will do.

      Particularly with Quartz. Extremely dense.

      A 24" overhang requires brackets. Up to 10" does not.

      It is also imperative, Carol, that the brackets like the ones you linked above are secured into the studs of the half wall, otherwise they serve almost no effect.

      What's the cabinet footprint in relation to the counterop? I'm wondering if there's a risk that the whole thing could tip over when someone leans on the overhang. In cases like this you need to consider center of mass of the entire system (cabinets, countertop, and person leaning on overhang). If a plumb line from the center of mass to the floor doesn't fall within the cabinet footprint, then you need to anchor the cabs somehow to prevent tipping or add legs or pony walls.

      Good point. Rule of thumb/standard is 2/3rd's on the cabinet, 1/3rd overhang, so 24" cabinet allows up to 12". (We consider 10" to be a safer allowance and 10" overhang doesn't bang knees!)

      Without a support, your overhang is going to be a cantilever. The rule of support is that for every foot of cantilever, there should be 2 additional feet behind the cantilever end that provide support.

      Therefore, to support an overhang that is 2 ft wide, you need to have 4 ft of island behind it, at the minimum.

      If you already have total 6' island dimension, no worries. But if you do not, either use brackets or decorative legs that will provide anchor to the floor. Legs come in all styles and shapes/sizes. Hope this helps!!

      Legs and stretcher bars to create a table effect.

      The 10" unsupported rule is for natural stone, not engineered stone which is usually 14". Estone has much more flexural strength, hence the longer allowed cantilever.


      It's a moot point here, but you'll need corbels attached to framing on reinforced cabinets or a steel frame to avoid the knee-knockers.

      If this is a straight run you could build end supports. My granite island bar is 100" long with a 24" deep eating surface and 18" knee space. Ends support a steel bar that runs under the overhang -- no 'knee knockers'. (Bar is framed and painted.)

      Sorry I didn't look closely at the pic I posted. We don't have a pony wall. Our metal supports span the entire 26" bank of cabinets and the overhang is 15". Our cabinets were custom built into our kitchen by a local cabinet maker, so they aren't going anywhere. They are nailed into the floor. You definitely need some support for a 24" overhang.

      Hi my over hang will be 3.5 feet. Would (2) Douglas Fur 6"x6" legs be enough support?

      hi — i really need help with my rectangular island. i wanted to use 2x24” cabinets with a 10” overhang for seating on 2 sides (long and short side). will i need to add support brackets? the cabinets will be bolted to floor . the counter top is quartz. thanks!

      ok, thanks. So I can even go up to 12" since it's Quartz. My concern is that the overhang is "L" shaped: Quartz footprint: 60" x 36"

      Cabinet: 48" x 24"


      Do you recommend support for this?

      If the estone is 3cm, I wouldn't worry about it; that's not much span.
