Abstract: There is disclosed a protective cover having a base member adapted to engage and mate with the peripheral lip of a sink whereby the opening and the edges thereof are covered and protected, the base member having a plurality of projections extending therefrom into the sink opening and adapted to engage the innerside surfaces of the sink to align the base member in the sink opening. An elongated rod is attached to the base member and extends into the sink opening, the rod having a resilient plug mounted thereon which is adapted to engage and seal the drain opening of the sink and to mechanically support the base member over the sink opening and in engagement with the peripheral lip of the sink.
