Abstract: A collapsible splash guard is provided that is relatively permanently secured to the lower surface of a toilet seat. The splash guard includes a base plate shaped and sized to substantially conform with the shape and size of the toilet bowl rim, a pleated, substantially U-shaped splash shield, and attachment members for attaching a first portion of the splash shield to the base plate. The splash guard also includes pivotal securing members for pivotally securing a second portion of the splash shield to the base plate and members for hingedly attaching the splash guard to the lower face of the toilet seat. The attachment members can either permanently or removable attach the first portion of the splash guard to the base plate. The splash guard can further include a flange which extends downwardly from an inner edge of the base plate such that the attachment members either permanently or removably attach the first portion of the splash shield to an inner face of the flange.
