I am adding a new bathroom and I want a drop in soaker tub(not a whirlpool). Toto has a cast-acrylic tub and I wanted to see if anyone had an experience with their tubs. I know they make good toilets but can't find much info on their cast-acrylic tubs. The other options I am exploring would be a Kohler Acrylic or American Standard Acrylic Fiberglass reinforced. Don't think I want a cast iron with porcelin because afraid it would get chipped. Any help will be appreciated.
