A toilet overflow is not one category of water. Clean supply water from a running fill valve is Category 1. Water that left the bowl after a clog is at least Category 2, and often Category 3. We class it before we talk about saving the pad and carpet outside the bathroom.
On a slab, the overflow runs under the vanity, under the door, and along the hall. Vinyl in the bathroom can hide how far it went. We meter the hall, the closet, and the unit below in a stack. If the water mixed with waste, we switch to black-water sewage protocol for disposal and disinfection.
Drywall at the base of a bathroom is paper-faced gypsum sitting in a wet, warm room. The Miami mold growth timeline after standing water still applies. An overflow that sat overnight is already in that 24 to 48 hour window.
Do not use household fans in a Category 3 overflow. You will aerosolize it. Shut the supply at the angle stop, photograph the floor, and call (305) 390-4900.
Technician insight
If the water is outside the bathroom and you can smell it, treat it as Category 3 until proven otherwise. Saving a hall carpet is not worth spreading bowl water into the living room with a fan.
