Abstract: A system for containing the splashing produced when using a toilet plunger to unclog a flush toilet is comprised of a substantially flat stiff splash plate that covers the upper opening of a toilet bowl when the plate is rested on the toilet bowl rim. The plate is visually transparent and has a central aperture for a plunger handle to freely pass through. A gasket is interposed between the plate and the toilet bowl rim and is formed of an absorbent paper material that may be disposed of by flushing it down the toilet drain after use. A method of using the splash plate and the gasket utilizes the transparency of the splash plate and the disposability of the gasket. The splash plate may optionally have stiffness enhancing features including a contoured portion and a perimeter flange. A kit of equipment has a splash plate, a gasket and a reclosable envelope for holding the splash plate and gasket.
