As a designer or specifier, how do I know what toilet fixture will perform? What type of fixture does my client or customer need? Finally, what toilet should I specify? All questions asked by the design professional as the plans and specifications are developed. (Or, at least, they should be asked!)
Whether for a home, business or institutional building, toilet fixtures can be the one item that either annoys contractors (call-backs) and facilities managers (maintenance requests) or gives total peace of mind by functioning to everyone’s satisfaction.
Nearly everyone in North America has likely experienced some degree of dissatisfaction with some toilet fixtures of early 1990s. Clogging, double-flushing, and generally poor flush performance characterized some of the very early 1.6-gallon/6.0-Litre fixtures . . . and that “reputation” seems to still remain with some consumers.
In direct response to these issues of the 1990s, the water utility industry took a groundbreaking step in 2002 by first stating: “We can no longer encourage our customers to replace their old water wasting toilets with new ultra-low-flush toilets, nor should we be subsidizing (with rebates) product that doesn’t work satisfactorily!” 22 organizations in the water utility industry stepped forward and funded the development of a more rigorous test protocol, which ultimately became known as Maximum Performance (MaP) testing.
Designers and specifiers have the opportunity to review (free-of-charge!) the performance of 4,351 DIFFERENT TANK-TYPE toilet fixture models, all of which have been tested at independent laboratories. In addition, 573 different MaP-tested flushometer combinations for commercial applications are listed.

NEW!! 38 different toilet models designed for children and juveniles.
Designing or equipping a day care center? A preschool, kindergarten, or primary facility and need 'child-sized' water closets? This listing includes both gravity-fed, tank-type toilets as well as bowls for flushometer applications. Bowl heights range from 10 inches (254mm) to 14 inches (356mm). (Note that adult-sized conventional height bowls and ADA-classified bowls generally range from 15 to 17 inches, or 380mm to 430mm) Go here to download the listing
Since its development and release in 2003, MaP has been a major driving force in the improvement of toilet flush performance in North America. In 2003, the average MaP score of all tested toilets was about 336 grams (12 ounces), while by 2017, the average score had more than doubled to 882 grams (about 31 ounces)! The competitive pressure to improve fixture performance from the unacceptable levels of the early 1990s, together with MaP as a vehicle to measure performance, resulted in many hundreds of very high-performance 21st century models, for which the manufacturers must be given great credit!

Remember, though, MaP is a VOLUNTARY testing program. Manufacturers may choose to participate, but are under no compulsion to do so. Therefore, not all toilet models found in the marketplace (at the wholesalers, distributors, retail outlets, plumbing supply houses) will have been MaP tested. But, since 2003, over 5,500 different toilet models have been tested, about 5,000 of which are reported in the several public databases (tank-type and flushometer valve) on this website!
