Laundry Room Inspiration

I'm re-doing our laundry room and I'm looking for an unusual or antique sink, preferably made of zinc, terra-cotta, copper, concrete, or soapstone. I know I could have one made, but it would be great to find an old one. I was at the Brimfield antique fair yesterday and walked for miles and miles wading through thousands of dealer's items, and remarkably didn't find anything I could  use. If anyone reading knows of anywhere to find anything like this, please let me know. Here are some lovely inspirations of what I'm thinking of for the room.

I love this one

I could also possibly go with a white porcelain farmhouse sink.
These are pretty easy to find, but it would be great to find a unique one as well,
if anyone has any suggestions.
