The present invention provides a plumbing fixture fitting having a spray mode with improved spray performance. The fitting includes a spray face. The spray face includes nozzles. The nozzles are operable to deliver water from the spray face in the form of a spray. The spray includes streamlets. A velocity of the spray from each of the streamlets is greater than approximately two-hundred fifty inches per second at a flowing pressure of approximately sixty pounds per square inch. In exemplary embodiments, each of the streamlets has a substantially uniform width along an entire length of the streamlet, an average unbroken length of the streamlets is greater than approximately two inches at a flow rate of approximately thirty-seven thousandths gallons per minute, and a splash created from the spray is less than approximately twenty percent at approximately one and a half gallons per minute.
