We are remodeling our bathroom. I want to replace our steel tub with a cast iron bath tub. The specs of both tubs are approx 180 vs 300 lbs. Are their any consrtuction issues that arise, due to the add'l weight, whether wall or floor, when placing a cast iron tub into the same area as the steel tub is located? 32 x 60 inch tub.
