americast is junk
all americast is , basically a cheap steel tub with an epoxy resin base .'
I dont like them, they have a tendency to lose their luster after only a few years. the americast kitchen sinks do wear out fast.
also if you drop something in the unit, you can chip the tub....
even cast iron will chip... but its more durable and it looks good after a long while.
acutally, I feel that the Sterling bath fixtures are as good as any for durability.
If you put concrete under one it feels like cast iron and it wont ever chip.
Short of takeing a claw hammer to it, it is literally indestructable.
