Water & Bathroom


Money down the toilet bowl (Clipping path)


– About 25% of most Americans’ daily indoor water use is in the bathroom. If you can reduce your use here, it’ll go a long way towards reducing your water use overall!

– Toilets are by far the main source of water use in the home, accounting for nearly 30 percent of an average home’s indoor water consumption

– Showering is one of the leading ways we use water in the home, accounting for nearly 17 percent of residential indoor water use

– If your toilet was manufactured before 1995, consider an upgrade to a new WaterSense-labeled fixture; it could save you up to 10,000 gallons per year!

– A typical showerhead flows at 2.5 gallons per minute or less. The average shower in the United States consumes 17 gallons and lasts just over 8 minutes.

– Leaking or running toilets in a single-family home can waste as much as 500 gallons of water per day!

Water–Efficient Shower

In an average home, showers are typically the third largest water use, after toilets and clothes washers. The average American shower uses 17.2 gallons and lasts for 8.2 minutes at average flow rate of 2.1 gallons per minute.

Showering is one of the leading ways we use water in the home, accounting for nearly 17 percent of residential indoor water use – for the average family, that adds up to nearly 40 gallons per day.

The average family could save 2,900 gallons per year by installing “WaterSense” labeled showerheads. Since these water savings will reduce demands on water heaters, they will also save energy. In fact, the average family could save more than 370 kilowatt hours of electricity annually, enough to power a house for 13 days.

By replacing an older, inefficient showerhead with a “WaterSense” labeled model, the average family can save the amount of water that it takes to wash 70 loads of laundry and conserve enough energy to power a home for 13 days every year!


Duration- The duration of the shower has a direct effect on water usage. A 20-minute shower will use twice as much water as a 10-minute shower taken at the same flow rate.  A shower timer might be a helpful tool in reducing the length of your showers

Flow Rate- Before 1980, many showerheads exceeded 5 gpm. Current national energy policy act standards mandate that all showerheads manufactured in the U.S. have a maximum flow rate of 2.5 gpm.  Showerheads are also currently available at flow rates of 0.75 gpm, 1 gpm, 1.5 gpm, 1.75 gpm, and 2 gpm.

Shower Water Saving Tips:

– Pay attention to the length of time spent in the shower. Try taking a shorter shower of around 5 minutes.

– If you shower is equipped with an on-off switch use it while you are soaping and shampooing.

Toilet Therapy

Toilet flushing is the single highest use of indoor water in the average home, so it also presents a prime opportunity for water conservation. With the average person flushing five times a day, toilets make up about 30% of overall household water consumption.

In a home with older toilets, an average flush uses about 3.6 gallons, and the daily use is 18.8 gallons per person per day. In a home with ultra-low-flow (ULF) toilets, with an average flush volume of 1.6 gallons the daily use is 9.1 gallons per person per day.

A family of four using an older toilet will use approximately 26,000 gallons per year in toilet flushes, while a family with a ULF toilet will use approximately 11,000 gallons per year in toilet flushes, achieving a savings of 15,000 gallons per year.

Traditional Toilets – Toilets made from the early 1980s to 1992 typically used 3.5 gallons per flush or more. Toilets made prior to 1980 typically used 5.0 to 7.0 or high gallons per flush. The oldest toilets can use more than 8 gallons per flush!

Ultra Low Flush Toilets (ULF) – An Ultra-Low Flush toilet flushes at a maximum of 1.6 gallons (6 liters) per flush. Federal law currently mandates that all toilets manufactured in the U.S. must use an average of 1.6 gallons (6 liters) per flush or less. This law was enacted in 1992 and put into place in 1994 in an effort to improve water efficiency nationwide and coordinate various state standards.

High Efficiency Toilets (HET) – An HET is a toilet that flushes at maximum of 1.3 gallons (5 liters) per flush. There are more than 1,100 models of HET toilet on the market today. New fixture models have been introduced and the performance of HETs has improved dramatically. Today, HETs outperform their ULFT (1.6 gpf/6 liters) predecessors as well as the 3.5 gpf (13.2 liters) toilets that were installed in the 1980s

Dual-Flush Toilets (DFT) – Dual-Flush toilets are a type of HET with a full flush and a half flush capability. The average flush volume of a modern dual flush toilet is 1.1 gallons (4 liters) or less. If your home has a dual flush toilet try to use the low volume flush mode as much as possible. Experiment to see just how much waste the “low flush” setting can handle.

Flush Type:

Single flush toilets have only one fixed flush volume.

Dual flush toilets have two flush volume settings, a full flush for solids, and a reduced flush for liquids.

Flush Mechanism:

Gravity-flush systems use the weight of the water stored in the toilet tank and the force of gravity when this water is released to generate flushing pressure.

Pressure-assisted flush systems use a pressurized vessel within the toilet tank to store and then force water into the bowl to generate flushing pressure.

Bathroom Water Savings Tips

– Replace your regular showerheads with low-flow showerheads. Save up to 230 gallons a week

– Keep your showers down to five minutes or less using a low-flow showerhead. Save up to 75 gallons a week per person

– Turn the water off while lathering-up in the shower. Then turn the water back on to quickly rinse. Save up to 75 gallons a week per person

– Take shallow baths, no more than 3 inches of water. Save up to 100 gallons a week per person

– Replace your older model toilets with new ultra-low-flush models. Save up to 350 gallons a week

– Check your toilets for leaks. Drop a dye tablet or a teaspoon of food coloring (avoid red) in the tank. If color appears in the bowl after 15 minutes, you probably need to replace the “flapper” valve. Save up to 100 gallons a week for each toilet repaired

– Never let the water run while brushing your teeth or shaving. Save up to 35 gallons a week per person
WaterSense Labeled Toilets- The WaterSense label is used on toilets that are certified by independent laboratory testing to meet rigorous criteria for both performance and efficiency. Only toilets that complete the third-party certification process can earn the WaterSense label.
