Toilets That Save Water: How to Cut Your Water Use This Summer (and Why Your Bathroom Is the First Place to Start)
We’re in the middle of summer and higher water bills are here, too.Between longer showers, garden hoses running at full blast, and the kids filling up the inflatable pool every other day, water use spikes across most American households between June and August, but here's something a lot of homeowners don't realize: the biggest water hog in your home isn't outside. It's inside and it's your bathroom. If you've been looking for practical, lasting ways to save water this summer, the toilet is the single most impactful place to start. In this post, we'll break down why, what the EPA recommends, and how the right toilet choice can make a real difference for your water bill and for the planet.
Why Bathrooms Use the Most Water at Home
According to the U.S. Environmental Protection Agency (EPA), the average American family uses more than **300 gallons of water per day at home. A significant portion of that happens in the bathroom and toilets alone account for nearly 30% of all indoor water use, making them the single largest consumer of water inside any residence.
Let that sink in for a moment. Nearly a third of every gallon that runs through your home goes down the toilet.
Older toilets, particularly those manufactured before 1994, can use anywhere from 3.5 to 7 gallons per flush (GPF). Even standard modern toilets sit at around 1.6 GPF. Multiply that by the number of flushes in a day, across a full household, and the numbers add up fast.
Quick math:A family of four using an older 3.5 GPF toilet flushes roughly 15–20 times per day. That's 52–70 gallons just from flushing — every single day.

What the EPA Says About Water-Efficient Toilets
The EPA's WaterSense program sets clear standards for water efficiency. A WaterSense-certified toilet must use 1.28 gallons per flush or less — that's at least 20% less water than the federal standard of 1.6 GPF — while still delivering a high-performance flush.
According to the EPA, if every U.S. home replaced its older, inefficient toilets with WaterSense-labeled models, we would collectively save:
- More than 360 billion gallons of water per year
- $5.3 billion in water and wastewater bills annually
These aren't abstract numbers. They reflect real savings — on your utility bill, in your community's water infrastructure, and in the broader environment. The EPA's WaterSense program makes it easy to identify certified products: just look for the WaterSense label.

Summer Is the Right Time to Make the Switch
Summer puts extra pressure on municipal water systems. Heat increases evaporation, landscaping demands go up, and communities often face drought warnings across many regions of the country. Making water-smart upgrades during summer months, rather than waiting, means you're contributing to conservation exactly when it matters most.
Beyond the environmental angle, there's a practical one: summer is often prime home improvement season. More people are renovating, remodeling, or adding new bathrooms to their homes. If you're already thinking about a bathroom project, this is the ideal moment to choose fixtures that work with you, not against your water budget.

And yes — it's EPA WaterSense certified, using just 1.28 GPF. You get the efficiency without sacrificing the flush performance you need.

Practical Tips: Save More Water This Summer, Starting Today
Upgrading your toilet is one of the highest-impact moves you can make, but it's not the only one. Here are a few additional ways to reduce bathroom water use this season:
- Check for leaks. A running toilet can waste up to 200 gallons per day. Drop a few drops of food coloring in the tank — if color appears in the bowl without flushing, you've got a leak.
- Shorten showers by 2 minutes. A standard showerhead uses 2.1 GPM. Two minutes less = over 4 gallons saved per shower.
- Turn off the faucet while brushing. Leaving it running wastes about 4 gallons per brush session.
- Upgrade to WaterSense fixtures across the board. Faucets, showerheads, and toilets all have WaterSense-certified options that reduce use without reducing comfort.
- Consider a bathroom addition instead of a remodel. With macerating toilet systems like the Sanicompact, you can add a water-efficient bathroom without the mess and cost of traditional plumbing work — a smarter investment any time of year.
The Bottom Line
Your bathroom is the largest water user in your home and your toilet is the biggest culprit within it. This summer, as temperatures rise and conservation becomes more urgent, it's worth asking: is your toilet working with you or against you?
The EPA's WaterSense program has made it simple to identify efficient options. And with solutions like the SFA Saniflo Sanicompact, going green doesn't mean sacrificing flexibility, performance, or style. It means making a smarter choice — one that saves water, money, and opens up new possibilities for where and how you design your living space.
Small changes add up. Start where the water use is highest. Start in the bathroom.
