How many gallons of water do we use in the shower?
There’s not much more relaxing than a nice long shower, but you might the using more water than you realize. How much water you use when you shower depends on a couple factors, the most obvious being the length of time you are showering. Another major factor is water pressure. While high-pressure showers feel great, they also use more water.
When factoring the average water pressure with an average shower length of 10 minutes, we can estimate that most people use about 33 gallons of water when they shower. Assuming you shower once a day, at 33 gallons per shower you would use enough water to fill up an average swimming pool each month! That’s a lot of water!
To more accurately calculate how much water you use when showering, take an old milk gallon and cut off the top just enough to fit your shower head. Turn your shower head on and time how long it takes to fill up the gallon. Then take 60 and divide it by how many seconds it took. The number you get is how many gallons /minute you use. For example, if it took 15 seconds to fill it up: 60 / 15 seconds = 4 gallons per minute.
