DMAX154, take the round inspection plate off in the shower stall and make sure the screw on fittings are tight. I had a leak after a shower but could never find it. Tightened the fittings and it went away. BTW, the fittings hold the knob base to the shower wall. Pull on the knob base and see if it feels loose. Bob
