Check our these tips for simple ways to save water in your bathroom.


Showers make up almost 25% of total household water use, so are a great place to save water in the bathroom:

  • Cutting your shower time by just 2 minutes can result in a water saving of up to 30%. Try using a shower timer or your favourite 4 minute song to time your showers.
  • By swapping to water efficient showerheads, households can save up to 20,000L of water per year. Look for the stars on the WELS label the more stars, the more water you will save. Be sure look at the flow rate (litres per minute) as this can vary substantially.
  • Don't waste the cold water as you wait for it to heat – collect it in a bucket and use it to water your pot plans and garden. You could be catching as much as 10L for every minute you are waiting for the water to heat up.


Toilets contribute to about 20% of indoor water use.

  • Upgrading your single flush toilet to a dual flush system can save up to 80L of water per day.
  • When replacing your toilet choose WELS 4 star models which use 3L for a half flush and 4.5L for a full flush. Be sure to replace both the pan and the cistern. Contact a Waterwise Plumber to install your new toilet.

Water efficient fittings

Go for WELS 6 rated taps in the bathroom or install flow controlled aerators, they are easy to fit yourself if your taps are threaded at the spout, or call a Waterwise Plumber for help.

Running taps

Turn off the tap while brushing your teeth to save up to 10L per minute. 

Leaks and drips

  • Each year the equivalent of around 700 million buckets of water is lost through residential leaks in Perth alone.
  • Leaking taps waste up to 10,000L per year! Fixing a dripping tap is easy, but if you need you can call a Waterwise Plumber to help you.
  • A constant trickle into the toilet bowl wastes around 9,000 litres a year. To check for this type of leak, simply place a sheet of toilet paper under the rim in the back of the bowl (do this half an hour after the last flush when the bowl should be dry). If the paper soaks up water, you have a leaking cistern and need to call a Waterwise Plumber to fix it.
