Are You Using Water-Saving Showerheads? Older, regular showerheads typically use between 15-20 litres of water per minute. A 10-minute shower would average between 150-200 litres per day, 1,050-1,400 litres per week, and 5,475-7,300 litres per year.
How many litres of water do you think an average shower uses? This depends on the length of the shower taken and the type of head on the shower. The average shower duration is approximately 7 minutes and the average shower volume is approximately 55 litres.
A full bath uses up to 80 litres of water whereas a five minute power shower uses about 75 litres. So, provided you don't take too long under the shower, water can still be saved. Remember to turn off the tap while you are actually brushing your teeth. A running tap uses 6 litres of water per minute.
An approximate calculation shows that we use between 8 and 15 litres of water per minute when showering. So,on average, for a five minute shower, we would use about 57.5 litres.
In the above chart, considering a 50-gallon bathtub for comparison with showers running at 2.5 gallons per minute, we found out that a 20-minute shower at full shower power consumes the same amount of water as a 50-gallon (190 liters) bath!
The shower
A water-efficient showerhead uses approximately 9 litres per minute.
If the flow rate is less than 10 litres per minute, you have low water pressure. A flow rate between 10 and 15 litres per minute is considered acceptable but can be improved. A flow rate that is above 15 litres per minute will be regarded as good.
If your home water outlets (i.e. taps and showers) can deliver over 15 litres of water per minute, this is considered good water pressure. Between 10 and 15 litres of water per minute is acceptable. Anything below this is considered poor.
Previous research by Energy Australia revealed 29 per cent of us hit the shower twice daily, while 9 per cent boasted three showers a day. Compare this to the shower-shy Chinese: 50 per cent claim to wash twice a week, while in Sweden less than 50 per cent of women bother with a daily wash. Squeaky clean?
The average 8-minute shower uses about 120 litres of water, whereas an average bath uses around 140 litres, depending on the depth filled. But installing an Oxijet water-saving shower head will reduce water consumption by at least 40%.
The standard door width in Australia is 820mm plus and architrave and wall space either side, so it's likely you'll want the room to be at least one metre wide. We always say to ensure a minimum of 900x900mm for an enclosed shower but a space of 1000x1000mm is preferable, if possible.
A 10-minute shower: 20 gallons. Average daily toilet flushes: 19 to 24 gallons. A washing machine load: 15 gallons.
A bath uses approximately 100L @ 40 degrees C. An average shower uses around 35L @ 40 degrees C (5 mins @ 7L per min)
The average shower lasts about eight minutes. Since the average showerhead has a water flow of 2.1 gallons per minute, each shower uses more than 16 gallons of water! Across the United States, we use more than one trillion gallons of water each year just for showering. Never fear!
Please remember that flow restrictors can be removed but it is illegal to remove them, so especially as licensed plumbers we aren't allowed to touch the restrictors.
For a standard house that's 20 litres per minute. This is measured at the front garden tap or your meter assembly.
Washing hands: 25.2 litres (12 times per day, on average) Brushing teeth: 5.6 litres (twice per day)
According to the U.S. Environmental Protection Agency (EPA), a full bathtub requires about 70 gallons of water, while taking a five-minute shower uses 10 to 25 gallons. You might argue that very few people fill the tub to the top, but a simple calculation shows that either way, baths use more water.
A Mira 8.5KW or 9.5 KW showers only require a maintained water pressure of 0.7 Bar and 8 litres per minute.
Each person uses an average of 100,000 litres of water per year, which works out to 274 litres per day. If you take this information and apply it to an average Australian family household of two adults and two children, that works out to more than 30,000 litres each month.
You can change your household daily hot water use results by adjusting your answers to previous questions. Medium equals between 64 and 95 litres used per person, per day. The average medium user uses 76 litres per person per day.
