<p>The invention provides an attachment for fitting over the overflow opening (14) in a bath, washbasin or sink, for hygenic purposes. The attachment comprises an open-topped container (20) having an outlet communicating with the overflow opening, and a baffle (36) in the container which is so arranged, that a water trap is provided in the container. Hence, the water trap acts to seal the overflow passage from the interior of the room in which the bath, basin or sink is fitted. The invention also provides a reversible back sealer (44) for the attachment, which enables the attachment to be used with either a vertical wall or with a concave wall.</p> |
