Can you find asbestos in a toilet?

Only if someone puts it there! It is not a naturally occurring item in a toliet!

Depending on when the toilet room was built, asbestos might be found in the floor tile or glue holding the floor tile in place, in the wall board or spackling compound, in the textured plaster, in the glue securing the baseboard, or in the caulking compound used around the tub or window.
