With a standard showerhead, around half a gallon more water will emerge each minute, so a 10-minute shower would use somewhere close to 25 gallons. *1 gallon = 4.54 litres.
Generally, taking a shower uses less water than a full bath. A standard showerhead flows at a rate of 2.5 gallons per minute . This means that a ten-minute shower only uses 25 gallons of water.
For instance, a typical shower uses about 10 gallons of hot water. So, if you have a 40-gallon hot water tank, you should be able to get four average-length showers out of your hot water tank. This also depends on how much hot water you use for other things.
With a large 5-gallon capacity, the Coghlan's comfortably provides over 4 minutes of continuous shower time.
With a low gpm head and full hot you should be able to get 20 min out of 50 gallons. Now you turn down the hot and add a little cold and you should get more time in a less hot shower. If you need more time you could turn up the water heater and use a less hot water to cold ratio. That would get you a few more minutes.
The average amount of warm water utilized to shower is 10 gallons. If a total of 5 people in your household shower in the morning, you should multiply 10 gallons by the total number of water usage sessions, which is 5.

In fact, heating the water to a pleasant showering temperature is at least twice as expensive as the cost of the water itself. Accordingly, water heating can quickly drive up utility bills and accounts for roughly 10-20 percent of an average household's energy bill.
