Do you have a laundry room you could use it in, as-is? I have a double drainboard cast iron double sink with metal cabinets in my laundry, next to the washing machine. I never dreamed I would use it for so many things, and can't imagine not having it. A smaller size like you have would be easier to work into a plan. Or maybe build a garden/potting shed and use it there? I can think of all kinds of uses. I don't think I'd separate the sink from the cabinet, though, to use it as an island. I think it belongs as a unit.
