Chamber pot

A chamber pot (also a jordan, a jerry, a guzunder, a po (possibly from French: pot de chambre), a piss pot, a potty, or a thunder pot) is a bowl-shaped container with a handle, and often a lid, kept in the bedroom under a bed or in the cabinet of a nightstand and generally used as a toilet at night. In Victorian times, some chamber pots would be built into a cabinet with a closeable cover.
