Toto Toilets Toto® Toilets

Low flow toilets save water, energy and the environment. In the late 90's 1.6 gallon-per-flush (GPF) legislation began passing in different states. Many manufacturers simply reduced the size of their tanks, resulting in poor performance & multiple flushes.

TOTO had already optimized their toilets, designing and developing low-volume flushing systems for decades. In fact, their rigorous flushing tests are more extensive than current industry standards which ensures outstanding one-flush performance and true water savings.
