Choosing a toilet may seem straightforward, but for plumbing professionals, contractors, builders, distributors, and specifiers, the right choice involves much more than appearance. As one of the most frequently used fixtures in any residential or commercial space, a toilet needs to deliver reliable flushing, efficient water use, proper fit, and long-term performance — and be easy to install, maintain, and support throughout its service life.
Start With Flush Performance
A powerful, reliable flush is one of the most important factors when selecting a toilet — but the best flush isn't necessarily the one that uses the most water. Performance depends on how the entire system works together: bowl geometry, trapway design, flush valve, water delivery, and gravity- or pressure-assist technology. Independent measurements, such as MaP testing, help compare performance by measuring how much solid waste a toilet can remove in a single flush.
Quantum® 1.28
Combines pressure-assist flushing with 1.28 gallons per flush and a 1,000-gram MaP rating — built for demanding, high-use applications.
Summit® 1.6
Also achieves a 1,000-gram MaP rating, giving contractors a dependable, proven option outside the high-efficiency category.
Maverick®
An ultra-high-efficiency toilet that uses 40% less water than conventional models, at 1.0 gallons per flush.
Finding a toilet with the best flush is ultimately about matching proven performance to the application — not simply choosing the highest number or the strongest marketing claim.
Balance Performance with Water Efficiency
Strong flushing performance and water efficiency do not have to compete. Well-engineered high-efficiency toilets can use 1.28 gpf while still providing dependable waste removal — Mansfield's Alto® 1.28, for example, combines 1.28 gpf water consumption with flushing technology built to keep performance consistent. For builders and specifiers, efficiency can also matter when meeting project requirements, plumbing codes, or sustainability goals.
The objective isn't simply to use less water — it's to achieve the necessary performance with less water.
Choose the Right Bowl Shape, Height, and Rough-In
Even a high-performing toilet needs to be the right fit for the application. Professionals should weigh:
Bowl Shape
Round-front bowls can work well in compact spaces, while elongated bowls provide additional seating area.
Height
Standard-height, Smart Height, and ADA-height options accommodate different comfort and accessibility requirements.
Rough-In
Confirming the distance from the finished wall to the center of the drain helps prevent installation issues and costly exchanges.
Application
Residential, multifamily, hospitality, institutional, and high-use commercial spaces can have very different performance requirements.
The best toilets to purchase are therefore not necessarily the same for every project.
Look Beyond What You Can See
Many of the details that determine toilet reliability are not immediately visible. For professionals, a reliable toilet can mean:
- Easier installation
- Consistent flushing
- Fewer leaks and callbacks
- Easier maintenance
- Better access to replacement components
Initial cost matters — but so does what happens after installation.
Consider the Manufacturer and Supplier
Searching for the best toilet brands can yield plenty of rankings, but professionals should look beyond brand recognition.
The Manufacturer
A strong manufacturer should provide documented performance, multiple configurations, technical specifications, installation information, replacement parts, and consistent product support.
It should also offer a proven track record built over decades in the market, such as Mansfield’s experience serving the U.S. plumbing market since 1929.
The Supplier
Supplier relationships are equally important. Established toilet suppliers can help contractors, wholesalers, and project teams source the right products and receive support.
Availability also matters. For professionals searching for toilets in stock, a reliable supply can make the difference between keeping a project on schedule and facing unnecessary delays.
Look for Manufacturing Expertise and Market Knowledge
Searches for reliable plumbing manufacturers show that buyers and project teams still consider deep market expertise critical. Rather than focusing solely on where a product is produced, industry professionals prioritize manufacturers who truly understand local standards, installation requirements, and supply chain demands.
Mansfield brings decades of experience in the American market, serving its specific needs since 1929. That legacy is backed by Corona, an organization with 145 years of industry experience, delivering robust production capabilities, dependable supply chains, and high-quality products built for long-term performance.
So, What Makes the Best Toilet?
When determining the best toilets to purchase, professionals should consider the complete picture:
The toilet with the strongest marketing claim isn't automatically the toilet with the best flush for every project. The right toilet is the one engineered to perform reliably where it will actually be used.
Frequently Asked Questions
What determines a toilet's flush performance?
Flush performance depends on how the whole system works together — bowl geometry, trapway design, flush valve, water delivery, and gravity- or pressure-assist technology — rather than water volume alone. Independent MaP testing measures how much solid waste a toilet can remove in a single flush, which is one useful way to compare models.
Does a high-efficiency toilet flush as well as a standard one?
It can. Mansfield's Alto® 1.28 combines 1.28 gpf water consumption with flushing technology built to keep performance dependable, and ultra-high-efficiency models like the Maverick use about 40% less water at 1.0 gpf without giving up flush strength.
What is toilet rough-in and why does it matter?
Rough-in is the distance from the finished wall to the center of the drain. Confirming it before installation — along with bowl shape, height, and the space's application — helps prevent installation issues and costly exchanges.
