In January we noticed strange water-filled bubbles in the paint on the exterior of one corner of our house.

This corner is also where our shower is. However, there are no water pipes in the walls with the problem. (Shower head and faucets are on an interior wall.) The shower tile appears to be in good shape. The tile goes about 6 feet up. Above that, they used plaster (not drywall). We've had handymen, plumbers and roofers look at this problem, and nobody can figure out what it is. The roof seems to be in good shape with no obvious problems in the attic.

We even went so far as to drill a few small holes in the plaster above the tile to look inside the walls. The wood and plaster on the interior of the wall seemed to be dry. However, the inside part of the exterior wall was covered with beaded water, like consensation.

We live in Southern California, so this is not an overly wet climate.

If anyone has a clue as to what this may be, we'd appreciate the input. It's driving us crazy not figuring it out.

Thank you!

You don't mention the exterior surface material/construction....or the floor construction......but I suspect you have a failure of the shower pan or tile wall allowing moisture into the stud cavities......

My first guess would be that water from the shower is getting onto the floor and leaking into the floor or wicking into the wall. Second guess would be an air leak on the exterior. Humid air hits an A/C vent and condeses.
