Craigslist is an excellent option. You could also contact your local Habitat for Humanity and see if they might interested in it as a donation.

Your counter may or may not be in one piece when removed.

I would donate to Habitats for Humanity - presumably the installer is going to be removing the counter and you could ask him to drop it off for you. Or just give it to the installer as perhaps he has some use for it. I got rid of some stuff by just giving it to my workers.

Selling granite seems like it would be a too much hassle for whatever small amount of money you would get.

Flipper are always scouring Craigslist for "finds."

You may find someone who will buy it, but you may have to give it away. The reality is that much of the cost of granite counters is in the work that goes into fabricating them to the unique specifications of where they are being installed. A couple of years ago I had a small, granite, peninsula countertop made for my kitchen. The fabricator just had me pick out what I wanted from the leftovers of other jobs and then charged me to fabricate it to my dimensions.

Since it sounds from the dimensions you give that this may be a piece for an island, it may be easier to find someone who can make it work for them.

It just dawned on me that some people may not know that Craigslist has a Free Stuff category as well.

Locally, someone had a granite countertop for sale outside for weeks (maybe months, it was a while), but they wanted $400. Waaaaay too much money...if they did find a buyer, rather than throwing it away, I think they lowered their price.

For an outdoor kitchen project, I was thinking of looking for a piece of granite countertop. So, for the right price, there may be a buyer out there!!!

Not just flippers. I'm not ashamed to fix up my rental houses with leftovers, discards, and finds from thrift stores and garage sales. It's amazing how often people discard perfectly good building materials, and even appliances.

Craigslist is a good choice to advertise your granite. You could also put it on Freecycle. Or if you live on a moderately busy street, just put it out at the curb the day after trash pickup. Around here, stuff like that often vanishes in a day or two. If it doesn't walk, the trash collectors will (one hopes) take it at their next pickup, and then you can stop worrying.

simmtalker how much do you think that you will pay for 7 feet by 4 feet granite countertop?

With a sink hole cut in it.

Without the sink hole, I might pay $100. If it was good looking stuff. Not ugly brown/ gold/ speckled stuff.

With a sink hole, I wouldn't take it if it was free.

Assuming the dimensions/sink cut fit my project, I would probably pay up to $125, depending upon what granite it is.

This is the granite

A 7' x 4' piece of granite is not light. Need some strong backs to move that. Either ask the installers to take it (and maybe they give you a slight discount on a new slab) or see if local Habitat or similar salvage operator will take. This is not something that you can haul away in a pickup truck. Need to make a rack to fully support it for transport and the right heavy duty dolly sure helps. Best of luck though.

It will probably weigh 500-550 lbs if it's 1-1/4" thick. More if thicker.
