About 33 to 49 L per person per day, depending on the efficiency of the shower head.
Explanation:
In 2012, the American Water Works Association determined that the average shower head in use has a flow rate of 2.2 gallons per minute (8.3 L/min).
In the same study, they determined that the average household with efficient shower heads used 8.8 gal (33 L) per person per day, but 13 gal (49 L) per person per day if they had less efficient showers.
