High Efficiency Toilets should be able to flush using at least 20% less water than is mandated by law and not need to be flushed more than once to do their job. They should require minimal cleaning with environmentally unfriendly detergents. They should flush quietly. They should be user friendly and comfortable. And they should be available in a wide variety of design styles that fit with the existing (or future) bathroom décor. These are the guiding principles that drive our design of high performance, High Efficiency TOTO toilets.
