I went and picked up (free!) an incredibly heavy antique Nustone concrete sink with two tubs and fancy cast iron legs. Appears to have been manufactured 2/3/1925 which is the year the house it came out of was built. It's about 4'x2' and 14" deep and has a soap holder molded into the divider, as well as a screened portal between the two tubs. Had this exact same utility tub set in my parents' 1st home growing up. I'm going to use it as an outdoor utility sink.
