I wanted to hang a cast iron sink on the wall of our laundry room, but our contractor says the wall can't support the weight, and that we need a freestanding sink. I like this Kohler sink, but it's been discontinued. Anyone have any ideas for alternatives? The sink doesn't have to be cast iron, but I didn't want something too utilitarian since guests will be walking by the laundry room in order to use the guest bathroom. Thanks!
