How can I save water in the bathroom?

Here are 20 tips to reduce water use in your bathroom.

1. If your shower fills a one-gallon bucket in less than 20 seconds, replace the showerhead with a WaterSense® labeled model.
2. Shorten your shower by a minute or two and you’ll save up to 150 gallons per month.
3. Time your shower to keep it under 5 minutes. You’ll save up to 1,000 gallons per month.
4. Toilet leaks can be silent! Be sure to test your toilet for leaks at least once a year.
   Put food coloring in your toilet tank. If it seeps into the bowl without flushing, there’s a leak. Fix it and start saving gallons.
5. When running a bath, plug the bathtub before turning on the water. Adjust the temperature as the tub fills.
6. Upgrade older toilets with water-saving WaterSense® labeled models.
7. If your toilet flapper doesn’t close properly after flushing, replace it.
8. Use a WaterSense® labeled showerhead. They’re inexpensive, easy to install, and can save you up to 750 gallons a month.
9. Turn off the water while you brush your teeth and save up to 4 gallons a minute. That’s up to 200 gallons a week for a family of four.
10. If your toilet was installed before 1992, purchasing a WaterSense® labeled toilet can reduce the amount of water used for each flush.
11. Consider buying a dual-flush toilet. It has two flush options: a half-flush for liquid waste and a full-flush for solid waste.
12. Plug the sink instead of running the water to rinse your razor and save up to 300 gallons a month.
13. Turn off the water while washing your hair and save up to 150 gallons a month.
14. When washing your hands, turn the water off while you lather.
15. Take 5-minute showers instead of baths. A full bathtub requires up to 70 gallons of water.
16. Install water-saving aerators on all your faucets.
17. Drop tissues in the trash instead of flushing them and save water every time.
18. Look for WaterSense® labeled toilets, sink faucets, urinals and showerheads.
19. One drip every second adds up to five gallons per day! Check your faucets and showerheads for leaks.
20. While you wait for hot water, collect the running water and use it to water plants.
