We live in a mobile home (27 yrs. Old); it has fibergalss tubs. One of the tubs has cracked right around the bottom drain hole and water can now leak underneath the floorboards. A man tried applying a silicone sealer type product around the drain area which didn't hold.
My question is can a repair be made to the drain area (ie a wider drain hole) be installed instead of having to put in a whole new tub?
