We had a full bathroom renovation start while we were out of town. We just came home to discover that our contractor installed our toilet with the supply line leaking. The tile floor beneath the toilet was not yet grouted:
The kitchen is below this toilet/bathroom. The water leaked through an area of plaster ceiling roughly 3 feet by 3 feet, dislodging some paint and dripping into the kitchen:
(This is in the United States.)
I'm wondering: Is this ceiling damage superficial? Can it be remedied with a simple coat of paint, or does this need to be torn out and replaced? I'm interested in the community opinion so I don't have to rely only on what the contractor tells us.
