Industry Analysis



The average person flushes the toilet 5-6 times per day. They turn their faucets on and off approximately 6 times per day, with 4 of those being in the bathroom, and 2 in the kitchen. A household with children will flush 17 times per day, on average. They will turn their faucets on and off 19 times per day, with 13 of those being in the bathroom, and 6 in the kitchen.

Research Strategy

To process for obtaining toilet usage was straight forward. After locating the number of flushes each day for an individual, the average family size and household size was obtained. Then these numbers were multiplied to get the total number of flushes.
Obtaining data for faucets was also very straightforward. To estimate and triangulate these numbers in terms of kitchen and bathroom use, an assumption was made. Research states that bathroom faucets account for more water usage than in the kitchen. Therefore, the assumption was made that two-thirds of the water use was for the bathroom, and one-third was for kitchen use. An adjustment was made to the stated three minutes per use when using faucets after research was located that stated the majority of bathroom use, like face and hand washing, was around one minute. Brushing teeth, which is likely to happen less than hand washing, takes two minutes. Therefore, taking all of this into account, 1.5 minutes was used instead of 3 minutes.
Additional data that was located during the research process has also been shared below.

Household Data

  • The average American household consisted of 2.52 people in 2019.
  • The average American family consisted of 3.14 people in 2019.
  • There were 1.93 children per family in 2019.
  • 20% of households are married with children.
  • 27% of households are one person households.
  • 16.6% of families have children under the age of 3. 18.5% families have children between the age of 3 and 5. 32.1% of families have children between the ages of 6-11, and 32.5% of families have children between the ages of 32.5%. Considering that over 83% of families have children who would be using the faucets and toilet, the effect of having small children on the overall usage is most likely not significant.

Toilet Flusing Data

  • The average person, according to the Water Research Foundation, flushes 5 times per day. This number has remained constant, and has not changed since their 1999 report.
  • The average family uses 33.1 gallons per day to flush their toilet.
  • The average person uses 14.2 gallons per day to flush their toilet.
  • A toilet, on average, uses 2.6 gallons per flush.
  • These numbers are consistent with the average of 5 flushes per day, and indicate this number is slightly more than five flushes. (14.2/2.6=5.46). Therefore, we will use the average of 5-6 flushes per day.

FaucetData- Bathroom & Kitchen

  • The average person uses 11.1 gallons per day from their faucets (bathroom and kitchen combined). They run the faucet for 8 minutes per day, per person.
  • Having small children in the household results in less faucet usage than having older children and teens in the household.

Bathroom Faucet Data

  • Bathroom faucets are used more than kitchen faucets, and account for the most usage.
  • The average person runs their faucet 3 minutes per use in their bathroom.
  • The average flow per minute in a bathroom faucet is 1.5 gallons.
  • The majority of new homes have 2 bathrooms (60%). 4% have one bathroom, 27% had three, and 9% had four or more. The US Census only counts the number of rooms and bedrooms in existing house, not bathrooms. 2011 median surveys, according to the US Census, the majority of houses had two bathrooms.
  • Women are more likely to wash their hands after going to the bathroom when compared to men (61% and 40%).

Kitchen Faucet Data

  • The average person runs their kitchen faucet 3 minutes per use in their kitchen.
  • The average kitchen flow per minute in a kitchen faucet is 2.2 gallons.

Overall Usage Data

  • Usage is lowest during the night hours (11pm-5am).
  • It is highest during the morning hours of 5am-11am.
  • Moderate usages are noted from 11am-6pm.
  • High usage is noticed during the evening hours of 6pm-11pm.
  • Working outside the home affects usage data. Before the pandemic, approximately 10% of workers, worked from home. Since the pandemic, 51% of workers have transitioned to working at home, although those numbers are likely to decrease as the country deals with the pandemic.
