Shower Water Footprint Calculator

Estimate yearly water from showers.

Shower length

Flow rate (L/min)

Showers per week

Yearly water 26,208

Yearly water 26.208

Formula: annual = minutes × flow × showers/week × 52

Step-by-step with your numbers:

1. Values used:

2. Shower length = 8

3. Flow rate = 9 L/min

4. Showers per week = 7

6. Yearly water = 26,208

7. Yearly water = 26.208

Did we solve your problem today?

Estimate the water your showers use in a year.

The math behind it

annual water = minutes × flow rate × showers per week × 52.

8 min, 9 L/min, 7/week → ~26,208 L/year.

Save water?

A low-flow head (≈6 L/min) and shorter showers cut this a lot.
