Thanks guys. I know I need electrical there. It's a pretty big island. As much as I'd just rather not deal with it, I know we'd end up hating that big of an island with no electrical.

We're not doing a sink as we don't really need another sink, the island will only be 42" from the current sink and we never do prepwork on the other side of the kitchen (it's got a desk)

Is there a way to know (other than the stamp in the garage) if I've got a post tension slab?
