How many gallons of water does that average shower use?

Answer 1

It mainly depends upon the showerhead.

The original generation of showerheads typically dispensed 3.5 to 5.0 gallons per minute (gpm) which would be between 13 and 19 liters.

The first generation of water-saving showerheads dispensed about 2.2 to 2.5 gpm, which would be roughly 9 liters. In the USA, federal law requires new showerheads to have a rate of 2.5 gpm or less.

The newest generation of low-flow showerheads use new engineering technology to achieve rates as low as 1.5 gpm, which is less than 6 liters.

There is a huge possible range. It depends on the water pressure and the type of shower head being used.

Answer 2

I depends on what type of shower head you have. Most newer water saving shower head have a flow of 2 gallons per minute.
Federal regulations mandate new shower heads flow less than 2.5 gallons per minute with a line feed pressure of 80 pounds per square inch. Although actual consumption varies with water pressure at the shower head inlet and the exact flow rate of the shower head, a reasonable average for a 5 minute shower using a low-flow head would be 7-8 gallons of water. This is because most homes have far less than 80psi line pressure, the typical pressure being around 50psi. Older high-flow or unrestricted shower heads in systems with more typical 50psi water mains pressure can flow over 4 gallons per minute. A 5 minute shower would use 20 gallons of water with an older unrestricted shower head, although it could be more.

Answer 3

I have two answers depending on whether Flow restrictor has been removed or not:

1. If flow restrictor is still in the shower head, it uses 2.5 GPM(Gallons per minute). So a 20 min shower = 20X2.5 = 50 Gallons (= about 25 G of hot and cold water)

2. If flow restrictor has been removed, it uses about 6- 7 GPM of water = 20X6 = about 120Gallons Minimum

Hope this helps!!

Answer 4

Approximately 2 gallons of water per minute, according to usgs.gov.

Answer 5

A single shower head flowing at 2.2 GPM (Gallons Per Minute) would use approximately 33 gallons in 15 minutes.

Answer 6

I'd estimate 25 gallons.

Answer 7

About 25 gallons.
