This is an antique sink. It has rust in it from where it was stored. It has no cast iron, nor a metal "core." A little CLR (lime, calcium & rust) remover will certainly clean it up good.
It would be excellent for a store, garage, mud space, bathroom, utility room or basement.
Measurements are 18" front to back - 191/2" throughout & 8" deep. It comes with water supply lines, drain piping & the faucet.
Don't hesitate to ask questions.
