    You know those big jugs you find in office water coolers? Those bottles hold 5 gallons of water. That’s how much water some older toilets use with every flush—in fact, toilets manufactured before the 1980s use up to 6 gallons per flush (gpf).

    Hopefully, your own toilet isn’t quite that old—but even toilets manufactured through the early ’90s use up to 3.5 gpf. Congress passed federal legislation in 1992 that required all new toilets to use no more than 1.6 gpf, and today, some states require that toilets use an average of 1.28 gpf. The toilets that meet the 1.28 gpf standard earn the EPA’s WaterSense designation.

    Even with those standards in place, your toilet is still the biggest water-consuming product in your home, according to the EPA. But replacing your toilet with one that meets the WaterSense standards can help you save up to 13,000 gallons of water and more than $140 every year.

    But is 1.6—or 1.28—gallons enough water to do the job?

    “Many of the 1.28-gallon toilet models have excellent or very good performance for solid waste,” says John Banta, the Consumer Reports engineer who oversees toilet testing. “In our tests, many WaterSense models perform just as well as—if not better than—some higher-gallon toilets.”

    In our important solid-waste test, we attempt to flush a big load of plastic balls, sponges with screws inserted for realistic waste, and more. It’s an extreme test, but it gives us a great idea of what these toilets are capable of—and even some of the lowest-flow toilets can do a fantastic job.

    We also evaluate how well a toilet cleans its bowl. CR’s test engineers leave a measured paint swatch on the inside of the bowl to see whether the toilet is actually sending water all the way around the interior when it’s flushed. If a lot of the paint remains on the side of the bowl after one flush, then—you guessed it—the toilet isn’t so great at cleaning the inside of the bowl.

    Below, Consumer Reports members can read about five highly rated WaterSense toilets, listed in rank order. All cost $200 or less and use an average of 1.28 gallons per flush.
