The present invention is directed to a microflush urinal that includes a piece of chinaware in fluid communication with a pre-existing water supply and a waste removal conduit. A valve means in electrical communication with each of a sensor means and a fluid manifold effects delivery of incoming fluid to a water delivery means. The water delivery means is desirably a nozzle means selected from one of a plurality of fluidic nozzles that delivers pressurized water through an ingress defined in a rear wall of the chinaware. The nozzle desirably oscillates water for full coverage of the urinal's rear and side walls. A tarp portion that aesthetically obstructs the ingress assumes a generally scalloped shape to optimize the water distribution along the urinal's rear and side walls. At least one trough is integrated into one or more urinal sidewalls to guide water from the nozzle toward the waste removal conduit.
