I have a 2 story home with big bathroom on 2nd floor directly above 1st floor kitchen. The shower must have a leak underneath it as we are unable to shower from pouring water through the ceiling into my kitchen. We have only been taking baths. I would like to know how to repair. The house is about 23 years old. I owned it the last 15 years. Only a few changes have been made. The ceiling is dry wall. Thank you.
