North Seattle plumbing / guide 24
A stain or drip below a bathroom can follow supply, drainage, enclosure, overflow, fixture, or water traveling from another point. The outline alone cannot choose among them.

Recent rain or freezing weather may be relevant in an exterior area, but bathroom-use timing deserves its own column. Keep both observations until inspection connects them.
Record the first ceiling change relative to showering, tub filling, draining, flushing, sink use, and periods of no water use above.
Stay away from sagging material, wet lights, fans, switches, and wiring. Do not cut the ceiling or run a deliberate overflow test.
What to observe now
Keep the notes factual. A visible clue can direct an inspection without proving what is hidden.
Measure from two walls and note height, edge, drips, or surface movement.
Write whether the change follows spray use and ordinary enclosure position.
Separate filling below the overflow from the later drain-down period.
Record flush, fill, faucet, and basin-emptying events independently.
Arrange entry above without opening the ceiling or accusing an occupant.
