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 1-gallon bucket in less than 20 seconds, replace the showerhead with a WaterSense® labeled model.
2. Shorten your shower by a minute or 2 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 4.
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 2 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. 1 drip every second adds up to 5 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.
