I bought an old tin bathtub and it is 7" long. It is 18" deep at the head end and tapers to 12" at the foot. It has a drain at the foot end. It is very much shaped like half of an old time coffin. I am wondering when it could have been made and where. I cannot find anything except the history of enameled, claw-foot tubs on the internet. The tub is probably not worth much as I did not pay much for it! It is very interesting, though.
