After a vanity supply-line leak
A supply line under a bathroom vanity can run for days before anyone notices. The cabinet box, toe-kick, and the paper face of the drywall behind it stay wet long after the floor looks dry. A surface wipe of the cabinet front does not reach paper that has been wet. Paper-faced drywall and particleboard or MDF that stayed wet and is soft or crumbling usually come out. Hard, non-porous surfaces that can be cleaned stay. How dirty the water was, how long it sat, and what the material is made of decide remove versus clean — not a blanket rule to gut the bathroom. If water is still running, that is a water-damage job first — start with water damage restoration.
