When we were in the granite shops we saw some slabs that were big enough to do that - others weren't. You need to go and look at various pieces.

That is exactly the size of mine - 9' X 5'. It is tricky to do because sometimes the corners chip off in transit. It took 4 tries to get my slab there in 1 piece. The wrong slab would arrive (too small) or the corners chipped off. Fortunately, one of the long ends is curved so those 2 corners of the slab could be a little ragged. Try to bring a template on brown kraft paper to see if the slab is big enough. Also, take a photo of your slab to make sure the slabe that arrives at the fabricator is the slab you picked!

any pics would be great (rennovatorjen)!!

That's not an island, that's a subcontinent! Many granites won't come long enough, or you'll have to wait for the exact right slab to come along. Quartz slabs are usually only 54" wide and 108" long, which means you'd have to have a seam in quartz. Ultimately, on a piece that large, a seam is a good idea anyway. There will be extreme problems transporting something so heavy (700+ pounds), as well as maneuvering something so large into your home (doorways, hallways, elevators). I'd also caution you that such a large island will really be a challenge to keep clean in the middle. A comfortable arm's length in two directions is as deep as you want to make any island. And large islands can be very tricky visually. They can totally dominate the kitchen and look inappropriate unless very well thought out. I'd step back and reassess the plan first of all, and reduce it in both length and width if I didn't want a seam. But, if you determine that the size is appropriate, seams aren't the end all. Done well, they are practically invisible. Especially in quartz, or a granite that doesn't have a lot of flow. COrian of course will not have an apparant seam no matter the size of the island.

109x60 in the granite business is considered an average to small slab.

Most materials are 115x70 on average with a large number of materials going over 120 long.

Your island size is not an issue.

If this is a remodel then making sure you can get the piece into your house will need to be considered.

I personally have been involved in the delivery of an island that was one piece, 127 x 52, it weighed nearly 900lbs. 6 guys carried it up 3 flights of stairs on Amelia Island. All things are possible. Another fabricator I know used a crane to lift a 3cm double laminated Calcatta Gold Island that was 120 x60 and weighed 1500lbs. The island was in a downtown penthouse on the 14th floor which is where the crane came in. They set it on the balcony from the ground. There were a lot of people holding their breath that day.

When we were looking at slabs the biggest ones we saw were quartzite, the real stone not the manufactured product. We saw luce di luna that was about 154" x 66". The same yard had smaller luce di luna that was also quite large at about 117" x 60". Most of the granite we looked at was around 60" to 66" wide and approx. 110" to 114" on the average. We are in central Florida but the stone yards said that we could search the entire world and not find anything too much different in terms of size if we wanted something bigger. Our big island is 9' x 4'. Hope this helps.

My island is about 38x101 and the granite I have generally doesn't come that large. I'm doing walnut (eventually) anyway, so it didn't matter to me.

Some granites are available in larger slabs than others, and it will depend in part on which granite you select. It certainly seems possible unless you fall in love with one that is only available in smaller slabs or your installer isn't willing or is unable to get such a large slab into your kitchen safely and in one piece. Remember, it does have to go through doors, sometimes up stairs and around corners depending on your situation. Cranes I am sure involve significantly more money, so it might also depend on your budget. If you find a slab you like large enough, it also won't give you much room to cut out anything you don't love on that slab. Since the center will be 2 1/2 feet from either side, I personally would have to lean over pretty far but could reach the center to clean it. My counter top at the bumpout in front of the sink is about 28" deep and I have to lean a little to reach the back. Yours will be 30" to the center from each side, but you might have a longer reach than I do. You need to decide if it will be a pain for you to clean all the time or not. I would consider cutting the width to 4 1/2 feet to make it easier to clean if it wouldn't interfer with your cabinet design or the other planned uses for the island, like an overhang with seating. If it would cause other major problems, it is certainly doable at 5 feet, just be sure it will be comfortable with your reach. I would also strongly suggest going to granite yards if you haven't yet and picking a color of granite before finalizing the plan in case you really love something that has been coming in smaller slabs. That became an issue with me when the slabs I liked were suddenly coming in much smaller for some reason, and the large ones were coming in a much grayer color than I wanted. Finding the right color slab in the right size became such a problem that I eventually went with Zodiac quartz, and even then ended up with a seam where I didn't really want one. In the end it turned out fine. Also talk to your counter top installer or KD about what other possible increased charges it might involve if that could be an issue for you.

I have no idea how to post a picture here. But cleaning is not an issue at all. My arm reaches the 2 1/2 feet to the center, then I go around to the other side and clean the other side. I work on the sink side, and my kids sit at counter height and eat on the other side. It is the best thing I ever did in my life besides give birth to them! Company comes over and just sits there at the island in the big cushy armchair counter height barstools, while I work and talk and have a view of the tv! It took 8 men to haul in the granite. I had to remove a support column to get it in, so I had to jack up the house while the support column came out to get the slab in. Then I put the support column back in through a hole that had to be cut in one end of the island, removed the other 2 temporary jacks, and voila! Everybody told me it couldn't be done, and nobody believes me when I show them the pics as I am a tiny girl.

Sorry, I missed that you are going with Quartz like I did. You will have to ask a fabricator because they need to abide by the manufacturers specifications and requirements, as well as slab size. Slab sizes are 52-56 inches x 118-120 inches. Since they warranty quartz, it has to installed by manufacturer trained installers, and they have minimum and maximum as well as placement guidlines for seams, overhangs, etc. A granite installer has a little more leeway in determining what they are personally comfortable with. The quartz installers may limit overhangs, require more support for them, etc. So it can impact your design. It is more than just available slab size.

Well, looks like I will scale back to at least 54" max - to avoid some of the hassles - went out and about today to Expo, Great Indoors, Lowes, etc - looks like a 48" - 54" may be the max width I would want.

I saw about a 13ft long one at Lowes - 48" width...it was with a 45 degree anlge in it - a couple raised sections - looked real nice - even with a couple seams.

The seamless island we put in our last kitchen was 9' x 5' - we used Colombia Juperana granite. It looked great, but the center was very under-utilized as I'm only 5'1" tall and couldn't reach that far. The one in our new kitchen is 4' x 8' and is also seamless and just perfect!
