Small amount of water slowly seeps out of the corner of my shower (red arrow), flow over the small mosaic tiled floor surface towards the center drain hole. My shower mud pan was constructed with a thick layer of plastic liner, where the edge rise ~12" above floor, similar to the picture I found online.
Last night I removed the shower faucet cover, turned off both the hot & cold service stops. I noticed a very tiny wetness around(under) the right service stop (confirmed by the paper at the blue arrow). This wetness is so little that it couldn't be the cause. Besides, all the water pipes behind the wall go thru the middle of studs, if they ever leaked the water would have stayed outside of the raised liner edge and would have damaged the ceiling of the downstairs which is not my case.
I noticed the seeped out water seems like having relatively higher concentration of calcium because it discolored the black grout of my shower floor.
I didn't use this shower in the past 10 days. Could it be condensation?
The curvy tiled shower wall is an exterior wall, exposed to the late afternoon sun. Outside temperature in the past 10 days was between 80~100F, I had AC set on at 80F. I'm puzzled why water appears inside the mud pan liner. Condensation?
