Shower leak out sides of bath and hall
Our shower stall sits on a concrete slab, typical of 40 yr. old Hawaii houses. It is tiled. I have just noticed that the grout on the bath and hallway tile looks wet. The shower sits between. It is coming from the plumbing wall. The inside base has been caulked and I can't find any cracks. A friend told me these stalls are lined with some kind of felt paper that has probably cracked at the base. Is there a quick fix since we will be moving in a year and don't want to replace the entire shower.
