Water Usage Rates
The typical family uses about 70% of their water in the bathroom. This is partly because water is used at a faster “flow rate” in the bathroom than in any other area of the home. Toilets and showers have a flow rate of 5-7 gallons per minute; dishwashers and clothes washers use less than three gallons per minute.
- Toilet: 5 to 7 gallons per flush (Non low-flow toilet)
- Shower: 5 to 7 gallons per minute (Non low-flow shower)
- Bathtub: 36 to 60 gallons per bath
- Dishwasher: 10 to 25 gallons per cycle
