Ok, the old tub is out and the bathroom is empty. We're leaning toward an Americast tub (available in the same size as the old tub, lightweight, and about $220 at the local store) for about $20 more we could get the cast iron tub (same size, a lot heavier). Since this is the masterbath on the second floor and we're installing the tub ourselves, my husband is adamant about the Americast tub. Now, we're not looking for anything especially fancy, but that cast iron tub sure seems to have durability going for it. Anyone have an opinion about Americast vs. cast iron?
