| I like the island in my attached drawing - but can it even be supported?
On the north end near the range I will have 4' x 4' of cabinets. On the seating end, what do I need? I am thinking the 2 corner posts plus a 18" (deep) cabinet centered under the middle. But is a 16" overhang in most places too much? Any other ideas? Any help from the stone experts? :) |

| What granite thickness are you considering? 2 cm. requires a plywood substraight, and 3 cm. doesn't. Generally, 16" overhang is too much according to the internet. I believe that you can extend the granite (from the cabinet side by a 1/3, so 2/3 over the cabinets and 1/3 extended. Your corner posts may get you away from further support. What does your stone fabricators say?? If your are going 3 cm., then s/s supports imbedded in the stone may get you where you want to be. Good luck. |

| When you say 'overhang' I'm assuming you mean the area where the stools will go for your legs to fit under. You're planning to use 18" deep base cabinets running down the center of the seating side of the island to help support the granite + the 2 corner posts on the south end, leaving 16" on both sides for seating clearance for stools and knees, correct? If that is indeed the case, then 16" should be just fine. 15" is the ideal minimum, with 12" being doable but not ideal and I've heard of people doing as much as 18". I don't think 1" in going to matter. Do double check with your granite & cabinet people though. They will also be able to walk you through the necessary support specs. Hope this helps! |

| I have 3cm marble and 15" overhangs on two sides. It is supported with 4 steel planks coming out from underneath. Here are pictures:

| Thanks for the pictures deb52899! That was very helpful. I love the navy cabinets. ronniner: I am doing 3 cm granite. I thought that 12" would be too shallow to sit at? Is that incorrect? Thanks for your help! |
|
| I'm doing 12" to sit at. I have a wet bar that has 8.5" and it is fine to sit and chat and have a drink. I have a dining room table I'll be using for dinner, so we wanted seating for people to visit me while I cook and for eating breakfast, snacks, etc. So, for me, 12" is adequate. If this will be your primary eating area, then I'd go at least 15" unless your family is short. |

| Part of the reason I want a little deeper is because I don't want my kids kicking the cabinets. :) So I will check with some granite places and see what they think. Thanks!! |

| Get a steel fabricator involved and you can have any type of overhang that you can envision. It won't be cheap, but it WILL be sturdy. Bear in mind that the cabinets that the steel is attached to need to also be designed for actual support, as in no 3/8" backs trying to hold corbels, etc. And those cabinets should be fully anchored to the floor, possibly with connections to the joists depending on the size of the cabinet/pedestal. When you have a large overhang and small central type support, the power of leverage comes into play and magnifies any potential force that gets applied to the top, and if the whole isn't engineered as a system, having someone lean against it could possibly crash the whole thing to the floor with the resultant casualties to property and even possibly life. |

| jillchristine, Our overhang is much more then the 12". From our pony wall we are 38" supported by 2 large corbels; from the end (see link) of the 2 corbels, we are about 13 beyond the ends. Personally I would not like the 12" overhang, we eat most meals here, and reserve our dining room for special guests or more then the 4 seats we have at the soap stone eating area. Our soap stone countertop/table is too high for normal seats as well; I believe that the stools are 30" seat height. Some may argue that 12" is enough, but then I feel like I'm perched and constricted too much to have most of our meals in that configuration. |

| Thanks ronniner - do you have a picture of your completed island?? |
|
| jillchristine, It's not really a stand alone island. On the other side of the pony wall is a 5" lower soap stone countertop with the stovetop in it. The eating area runs another 9' or so at the high eating bar, this run is 18" deep (also on the pony wall). I believe that this run sort of anchors back the eating area somewhat. I'll see if the inhouse photographer can post the pics, I promised them anyways, and the back splash has just been completed, so maybe in a couple of days(?). I may not have mentioned it but the stone fabricators have cut in some dados that we have placed LED lights into on both sides of the pony wall; so this included the 9' run as well as under the large eating area, along the stovetop area behind the sink. This sink run from stovetop to the end is about 13', this run also goes further then the upper countertop that is why some of the numbers given don't work out exactly. |

| A 2-for-1 photo:
These are the same supports as deb52899 showed above, as seen from below our 3cm granite. Our overhang is 14", which is lots of room for seating. |
|
| jillchristine, Where we have the 3 8" by 11" supports a 14" overhang, but the total depth is 18+"; 4 - 5" over the pony wall and 1 1/2" (or so) for the dado for the LED lights which shines down to the lower countertop.. My wife should have the finished soap stone pics at the link I've posted above in my prior post. |

| 15" overhang of 3cm quartz, used steel supports as shown (and painted white):

| You know it makes me wonder if they also reinforce the wood island itself and the floor below to hold such a heavy slab of stone! Re: 1000 pounds of soapstone. |

| ============================================= Get a steel fabricator involved and you can have any type of overhang that you can envision. It won't be cheap, but it WILL be sturdy. Bear in mind that the cabinets that the steel is attached to need to also be designed for actual support, as in no 3/8" backs trying to hold corbels, etc. And those cabinets should be fully anchored to the floor, possibly with connections to the joists depending on the size of the cabinet/pedestal. When you have a large overhang and small central type support, the power of leverage comes into play and magnifies any potential force that gets applied to the top, and if the whole isn't engineered as a system, having someone lean against it could possibly crash the whole thing to the floor with the resultant casualties to property and even possibly life. =========================================== This is what we have. Our bar sits on three steel corbels that were custom made by a friend of our granite fabricator. They are attached to a specially built wall that backs the cabinets in that section. The wall was originally the height of the bar but when they installed it, it really cut the view between the kitchen and great room and so there was much discussion (and delay) while a solution was found ie the corbels. The wall is anchored both to the floor and to the back of the cabinets. The counter is about 26" deep with overhangs from 20-24". It is shaped sort of like a Nike check. I drew it free form on the back of a credit card receipt and Kinko's enlarged it to just over 8 feet long. Let's say the drawing was pretty small and it took a bit of persuading at Kinko's and I had to sign a waiver and pay up front LOL but they did it. Here's the wall before we cut it down:
After it was cut, and you can see where the original steel plates were to be set in the wall to support the overhang as other posters have shown.
and the finished kitchen. The bar is rock solid. You could sit on it and it's not going anywhere (however don't let me catch you doing that - we are not taking any chances)
