Shower 9.5 L/min, toilet 6 L/flush, laundry 50 L/load, dishwasher 12 L/load, hand washing 9 L/min, watering 15 L/min and other taps 6 L/min. These are planning values, not meter readings.

Reference points: EPA WaterSense showerhead and toilet guidance. Real fixtures, local pressure, leaks and outdoor climate can change the result.
