American Standard's Deep Soak drain - is this really necessary?
American Standard sells a "Deep Soak" overflow drain kit for bathtubs that increases the water depth by positioning the slots in the overflow drainplate near the top instead of at the bottom. It's fairly pricey, pushing $100, whereas generic tub overflow drain kits cost $25. Can't I accomplish the same thing simply by installing the overflow drain cover and gasket upside down? Or is there something I'm not thinking of that would cause a problem?
