A drainage fixture for a sanitary device, such as a sink, lavatory, or bathtub having a drainage socket with a drain hole includes a drainage funnel and a stationary disk inserted into the drain hole of the sanitary device. A plunger, including a plunger head and a guide element, for closing the drain hole is positioned under the stationary disk so as to be movable between a closed and an open position. The drainage funnel has an upper rim portion forming a sealing collar for the plunger head in the closed position. The upper rim portion is recessed in the drain hole so as to provide space for a longitudinal movement of the plunger head between the closed and the open positions. The stationary disk is made of ceramic material of a color adapted to the color of the ceramic material of the sanitary device and has a diameter that is smaller than the diameter of the drain hole and at least as great as the greatest diameter of the upper rim portion of the drainage funnel so that an annular gap is formed between the stationary disk and the rim of the drain hole.
