I have a walk in shower/tub area. All tile. When the shower is used it is causing a ceiling tealk on first floor. The shower head is mounted on the wall, and you shower standing in the tub. When you take a bath it does not leak only when you use the shower. I am thinking it is the shower attachment? The tile is all well caulked. Could it be a water pipe within the walls?

Most shower/tubs share the same mixing valve but yours could be leaking at the diverter or higher up where the pipe turns to go out to the shower head. Remove the handle and the escutcheon plate (cover plate). Use a flash light to see if water drips inside the valve cubby hole behind the wall.

Chances are, you have a crack in the bottom of the tub. Your pipe from the valve to the spray head is not under pressure, the head makes it an "open pipe". When the tub is full, or someone is in it, their weight is evenly distributed. In a shower, all that weight is concentrated on the feet, much smaller area. That weight is opening the crack to let more water leak out. It probably leaks with the tub full some, but just not enough to notice.

One of the things I would check first is the point where the shower stream hits the wall. Over the years tile grout can shrink and allow water to seep past the grout and trickle down on the floor. Good luck and thanks for rating my reply, Tom

In addition: make sure your overlfow plate is well tighten and not loose or installed upside down...
