My upstairs bathroom has short wall between a tub and a sink, with a door just beyond the edge of the tub. Over the last few months, the floor just outside the door has become increasingly discolored, but I haven't been able to determine the source of the presumed water leak.
I have looked at the valve stems and the diverter inside the wall, and I see no evidence of leaking around them. Likewise for the shower arm, and for everything I can see on the sink side, including peeking back through the pipe holes toward the tub.
At the base of the door frame, there is some wood that is soft to the touch, and it's pretty obvious that something fishy was going on before I bought the place nine years ago, but that still doesn't help me trace the root cause. The discoloration in the picture below between the tile and the marble threshold is new and truly puzzling to me. And I realize that water could be splashing out from the corner of shower, but I have reason to believe that's not what's happening here.
Can anyone suggest what might be causing this, or suggest what I might do to better diagnose the problem? This is the top level of the house, so there is no further plumbing above this.
