You'll need electrical on that island, but you would need that anyway, so what's one more circuit added? And you will need to have the whole engineered so as to be firmly fastened together with the proper support for the overhang and firmly fastened to the floor. The "island" you've described is a huge safety hazard if done incorrectly. It all has to be engineered as well as designed. It would be very easy to tip over and crack someone's skull otherwise.

Thanks GreenDesigns. I am hoping maybe I can just buy a wine chiller in Lowes or do you have a suggestions as to wear to buy one? Hopefully my contractor knows what he is doing with the island as didn't seem to think we would have any problem with it - never mentionded tipping over which would definitely not be good as it will be heavy.
He is putting electrical outlets on the island now. I will ask about the wine chiller. thanks so much for reply.
