A lavabo is a device used to provide water for the washing of hands. It consists normally of a ewer or container of some kind to pour water, and a bowl to catch the water as it falls off the hands. In ecclesiastical usage it refers to both the basin in which the priest washes his hands and the ritual that surrounds this action in the Eucharist. In secular usage, it refers to a sink for washing hands; the room in which it is kept is the lavatory.
