Everything AND the Kitchen Sink
When the house was acquired I would have love'd to put the old kitchen sink "under glass" because it was like a piece of folk art. But that old issue of water damage had other ideas. One day I noticed the soap stone sink had sunk a bit in the back. After investigation I discovered that the support that held the soapstone sink in place had rotted out as a result of damage from a leaking pipe.
It was decided the rot was too bad and the sink had to come out. With little coaxing, the support gave way and the sink collapsed. No soapstone was damaged because I had bags of bubble wrap underneath to catch the piece.
Floor beneath turned out to have significant rot and water damage as well. No big surprise there. The floor looks solid but was completely rotted under that yellow paint.
