## Abstract

A toilet protection device prevents the human waste contents of a portable toilet from spilling/splashing onto the toilet and/or the walls/floor of the portable toilet enclosure. The toilet protection device includes an expandable rubber seal enabling the toilet protection device to fit in most, if not all, portable toilets regardless of shape or size. Moreover, by using a disposable cover, there is minimal cleanup of toilet protection device.
