We had our bathroom remodeled nearly two years ago. Everything was good until two weeks ago when we noticed the dry wall paint outside the bath tub was bubbling and pealing off. The condition worsened when a spot on the dry wall just an inch outside the top of the tub line softened and I was able to poke a hole through and water was coming out. We suspect that where the underside of the door track meets the surrounding tile was not sealed properly. As a result, water eventually escaped through the tile, and coming out of the wall.
When we remodeled the bathroom, the tub has a lip around all three sides, in front of which hardie-backer cement boards and tiles were installed. Contractor said, if there is water getting behind the tile, it will flow down to the tub and trapped by the lip. So it won't go behind the cement board. Since the under-edges of the surrounding tiles were all sealed with silicone, water now finds the way out underneath the shower door track. We asked the contractor. Their recommendation is that reseal all the edges inside the tub, making sure that no water can get behind the tiles, even to the lip. We are not sure if this is a permanent solution. Any advice?
p.s. I have a picture, but not sure how to save it in a size less than 19.6 kb. The website keeps rejecting my photo.
