NO,,,I meant the backsplash area of the kitchen cabinet side. Measure it out ,height and all and see where it comes on kitchen side. some sort of access is always GOOD. What kind of countertop do you have? . If all else fails take a ice pick and try sticking it thru from faucet side and see where it comes out,depending on whats on kitchen side. or a small wire that is easy to fill hole. If its a one piece tub shower you HAVE to come from back side to fix it,,,unless you wanna replace whole tub shower combo. Hope its easier than is sounds.
