A drain structure connecting a sink with a waste line. The entire drain structure is outside the horizontally projected extent of the sink so as to optimize the capacity of the sink. A vertically extending screen extending upwardly from the bottom of the sink is substantially coplanar with one sidewall of the sink so as to enhance drainage. A vertically extending tubular valve member outside of the confines of the sink is used to open and close the drain line and is actuatable from above the sink top. Said valve member acts as an indicator of whether the drain is open or closed and also provides an overflow. The valve member may be readily removed for cleaning or replacement.
