It leaked from the get-go. The puddling occured first, in underneath
cargo bay door , on the inside upper portion of the slam-latch door, and dripped downward, wetting the cargo floor.
Then, it would puddle, like your pic, next to shower, on the bathroom floor.
No one could find source. Finally, close to warranty end, my dealer recaulked
area where shower meets walls & floor. A minor fix,it seems, but for now, it sealed the leak ! I'm still not sure EXACTLY what they did, but thats what they told us.
Good Luck...Being on the road w/out a shower, sucks !

I put painter's tape where baballo's dealer caulked where shower wall meets the shower pan to see if that was the source of the leak. It stopped the leak completely.
