@boomerang,
that's a mighty expensive cow trough...
(one would have to have staff to clean it, methinks)
I play with old claw-foot tubs a bit, mostly as fishponds, but they are just old cast iron, and easily enough re-enameled by a professional.
(they are firken HEAVY...)
I wonder if powder coating would be a tough enough finish.
If so, that is rather inexpensive...
