A splash guard designed to protect the gap between the back of a sink and the adjoining wall or mirror. The guard has an upper edge and a lower edge. There upper edge is attached to the mirror, preferably through the use of suction cups. The lower edge is provided with a bendable bar which a user can bend—using hand strength—into any desired shape. The bendable bar is bent into a shape which conforms the lower edge of the guard to the posterior sink geometry. The lower edge is then placed immediately behind the posterior sink geometry.
