How can I save water in the bathroom?
Baths and showers
It’s easy to save water when bathing by remembering:
- On average baths use more water than showers.
- Check the temperature as you fill so you don’t need to add water at the end.
- Power showers use almost twice as much water as gravity-fed showers.
- Keeping showers to four minutes or less will ensure you don’t let excessive water run to waste. To help you keep track use a showertimer.
- Fix an aerating showerhead.
4 minutes in a gravity-fed shower uses about 35 litres of water
4 minutes in a power shower uses about 70 litres
A full bath uses around 80 litres of water
Flushing the toilet
Around a quarter of the water we use in the home is used to flush the toilet. How much water your toilet uses will depend on the size of the cistern.
- Most modern toilets have a dual flush toilet cistern and these are water efficient.
- If your toilet is older, you can reduce the amount of water used by fitting a Hippo or Save-a-Flush device. These are simple devices which reduce the capacity of the toilet cistern therefore using less water for each flush. You can request a free Hippo or Save-a-flush device here.
- When replacing a toilet look for low flush or dual flush models.
Leaky loos are one of the most common causes of unexpectedly high water use but aren’t easy to spot as the water just dribbles away down the pan, so they often go unnoticed.
A single leaky loo can waste up to 400 litres of water a day – the equivalent of five full bathtubs.
How to spot a leaky loo
If you can hear water flowing when the toilet has not been flushed, or if you can see a constant trickle at the back of the toilet pan, you may have a leaky loo.
- Wait until 30 minutes after the last flush then wipe the back of the pan dry with toilet tissue.
- Place a new, dry sheet of toilet tissue across the back of the pan. Leave it in place for up to three hours without using the toilet. (This may be best to do overnight.)
- If the paper is wet or torn in the morning, you have a leaky loo.
If you do have a leak and need a plumber you can find an approved plumber here.
- Remember to turn off the tap while brushing. This could save up to six litres of water a minute.
- Using a glass to hold a small amount of water for rinsing your mouth will also help save water.
Fix dripping taps
A dripping tap can waste enough water in a day to fill a bath.
- Replace tap washers when they become worn.
Washing and shaving
- Remembering to put the plug in your wash basin can save around two litres of water each time you wash or have a shave.
