A splash guard assembly for removable attachment to a split-ring toilet seat elevator or split-ring toilet seat includes a base splash guard adapted to fit within the gap of the seat or elevator and a raised splash guard adapted to slip over the base splash guard to extend the working height of the splash guard assembly. The splash guards can be used together or separately and independently to accommodate a wide variety of toilet bowls as well as split-ring and solid-ring toilet seats and seat elevators.
