Kitchen ceiling repair from 2nd floor shower leak
I have a 3 story home with big bathroom on 2nd floor directly above 1st floor kitchen. The shower (separate from jacuzzi tub) must have a leak underneath it as we are unable to shower from pouring water through the ceiling into my kitchen sink and the ceiling looks as though it is about to fall through from water damage. So, needless to say, we have only been taking baths. I would like to know how to repair/replace the ceiling. I assume once I have the old ceiling down I will be able to see where the leaking is occurring to fix that before replacing the ceiling. Thank you. I really could use some help.
