Shower Water Usage Calculator
Estimate how many liters of water your daily shower routine uses so you can plan conservation strategies or compare fixtures.
Actual water use depends on local pressure, plumbing design, and individual habits. Treat results as directional estimates.
Examples
- 7.6 L/min for 8 minutes ⇒ 60.8 liters
- 9.5 L/min for 5 minutes ⇒ 47.5 liters
- 12.0 L/min for 12 minutes ⇒ 144.0 liters
FAQ
What is a typical residential flow rate?
Standard fixtures in North America often deliver 9.5 to 12 liters per minute, while efficient models are 7.6 L/min or less.
How can I measure my shower's flow rate?
Fill a bucket with known volume for exactly 60 seconds using the showerhead. The liters collected equal your flow rate.
Does the calculator account for hot and cold water mix?
It totals all water volume regardless of temperature. To estimate hot-water demand, multiply by the percentage of hot water you use.
Can I compare shower vs. bath usage?
Yes—typical bathtubs hold 110 to 150 liters. Use this calculator to determine whether your showers consume more or less.
Additional Information
- Every liter saved in the shower can also reduce water-heating energy use, lowering utility costs.
- Low-flow showerheads rated at 6.6 L/min (1.75 gpm) can cut consumption by up to 30% without sacrificing comfort.
- Collect baseline data for several days to understand your household's average before committing to upgrades.
