PURPOSE: To reserve urine splattered to a urine dripping stone during urination in recesses to prevent the urine from flowing down to a floor which is to be used always cleanly by forming the plate-like urine dripping stone laid on the toilet room floor below a urinal and provided with recesses for reserving the urine on the upper surface.

CONSTITUTION: A toilet room 1 has a piping unit 2 consisting of a frame 3, counter 4, front face plate 5, water supply pipe 6, drain pipe 7 or the like disposed therein and urinals 8... for a man mounted to the front surface plate 5 of the piping unit 2. Urine dripping stones 10... provided on the upper surface of a plate-like body with a plurality of recesses are disposed below these urinals 8 and on a floor 9. Thus, the urine splattered to the stone 10 during urination is reserved in the recess so that the toilet room 1 can be kept cleanly by cleaning only the urine dripping stone 10. Also, at least 3-4 of the recesses of the urine dripping stone 10 are shaped to receive leg members of the other urine dripping stone 10 so that the urine dripping stones 10 can be safely stacked on each other.
