In our ever growing knowledge around water and conservation, knowing how much water does a shower use, is one of the things that will allow you to be a better global citizen. On average older style, showerheads can use anywhere between 15-20 litres per minute. So a 15-minute shower will use approximately 300 litres of water or over 100,000 litres of water per year per person.
The usage of water in a shower depends on your equipment
It is actually quite amazing when you realise how much water a shower can actually use, but the above figure is based on old inefficient shower heads and all new establishments have minimum efficiency ratings. A three-star showerhead will cut your water usage in half to around 9 litres of water per minute. That in effect would save around 50,000 litres of water per year per person.
The truth of the matter is that bathroom in general is an extremely water intensive room, especially the toilet. When you think about the clean drinking water that we flush down the toilet everyday, it seems kind of crazy. These are the privileges we do have living in such a great nation, but these are also the things we should consider when being good global citizens.

To figure this out we just double the amount you would use in 5 mins so the number would be around 200 litres of water.
How much do you use in 15 minutes?
If we keep following the rules from above a 15 minute shower will use approximately 300 litres of water.
