I have a basement bathroom shower that leaks, but not during the time when someone is showering, only after. I see water leaking into the adjoining utility room about 15-20 minutes after the person showers. The water comes from under the drywall -- no evidence of soaking the drywall at all -- and it runs across and down the concrete flooring in utility room into the floor drain. The stream of water is about 2" wide. There is absolutely "no" evidence of leaking in the bathroom itself where the showering occurs. The bathroom floor is completely dry. This trail of water has been observed coming into the utility room for some months now! Can anyone solve this mystery? Frustrated and
