Shower and Bath

You use how much water in the tub?

In London, the majority (34%) of a person’s daily water consumption is used for bathing. Of the water used, almost half is heated.

Heating water for bathing requires a lot of energy - in fact, 25% of the energy consumed in your home.

 You can lower your water and energy use, and save money, by: Water Sense Logo

  • Reducing your shower time
  • Installing a high efficiency showerhead - save up to 65 L of water each shower
  • Make sure the high efficiency showerhead has a WaterSense Label


Showers - Did you know?


  • A five minute shower with a standard showerhead uses 100 L of water    
  • The same length of shower with an ultra low-flow showerhead uses only 35 L of water

Drip, drop - it wastes a lot


  • 60 drops per minute wastes 727L of water per month
  • 90 drops per minute wastes 1174L of water per month
  • 120 drops per minute wastes 1623L of water per month

Wasting this much water makes your water bill skyrocket, and puts a strain on the wastewater system.


Small things you can do to make a big difference in your bill:


  • Install a water efficient (ultra low-flow) showerhead ensuring they are WaterSense Labelled
  • Take a five minute shower instead of a ten minute one.    
  • Take a shower instead of a bath. To see the difference, plug the bathtub drain while you shower to see how much water is used vs. your typical bath.   
  • If only a bath is possible, try reducing the amount of water you use in the bathtub by 5 cm (2 inches). It is best to not fill the tub more than 1/3 full.         
  • Plug the drain first, before you run bath water. Don't wait for the right temperature before starting to fill.         
  • Make sure your water thermostat isn't set too high. Extremely hot water that needs to be cooled down before you get in is a waste of water and energy.         
  • Repair leaky faucets by replacing washers.         
  • Always turn off your taps tightly so they do not drip.       
  • Insulate household water pipes so hot water will be delivered to your faucet in a shorter amount of time.

Think, before it goes down the sink

It 's important to become more aware of the water that goes down your bathroom sink. Letting the water run while you do other things - like brushing your teeth, brushing your hair, gargling mouthwash - is a waste of water and your money.


Did you know?


  •   Faucet aerators and water-flow reducers use up to 50% less water than would normally flow down your sink.


Small things you can do to make a big difference in your bill:


  • Turn off the water tap while brushing your teeth.  Fill a cup up with water for rinsing after   brushing.     
  • Turn off the water while shaving and washing your face.  Fill the bottom of the sink with a few inches of water to rinse your razor or wash your face with.        
  • When you're washing your hands, don't let the water run while you lather.        
  • Check every faucet for leaks.  Investing in an inexpensive washer can help you save hundreds of litres of water. This will also result in bigger savings on your water bill.        
  • Retrofit all of your household faucets with an aerator and a water-flow restrictor.
