Leaking Shower Symptoms

Please note the curb is swelled and the facing is wet. The curb is constructed of 2’ x 4’s stacked one on top of the other with the pan pulled over the top. This exposes to water, approximately half inch of wood on the top next to the door jam. Also the pan is nailed to the wood curb. When the nail heads rust away, a hole is left in the pan for the water to seep thru, wetting the wood curb and causing the swelling that causes the wall to bow and the tile fall off.

 

 

 

 

 

 

 

 

 

 

 

 

Notice the black band around the floor…

That used to be drywall.

 

 

 

 

 

 

Notice the rotted wood at the door jam…this is caused by that gap of the pan we mentioned before.

 

 

 

 

 

 

 

 

 

Notice the pan is exposed against the floor where the drywall used to be.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The standard rule in new construction is to install the pan flat or pitched down to the corners because of failure to pre-float or somehow raise those corners. Then to make bad matters worse, the drywall is installed all the way down to the shower floor on the inside of the shower pan. Thus the wicking begins as soon as the floor absorbs enough water…generally about 1 to 2 years after installation and use begins. The drywall begins to rot and disintegrate. This is sometimes discovered while cleaning the wall and the wall caves in. In tub situations, it is usually the soap dish that goes first. Molds and mildew are growing rapidly. In the absence of pre-floating the floor in a shower situation, the rough in pipe is a virtual freeway for termites to gain access to your inside walls thru the gap left where the rough in pipe comes up thru the slab.
