Powerful Water Miser

Kohler’s water-conserving single-flush Highline 1.0-gpf toilet combines the force of gravity with a precision-engineered tank, bowl, and trapway to create a powerful siphon during the flush while still conserving water. It exceeds the requirements for MaP Premium, the most stringent industry standard for high-performance toilets. Kohler says that the Highline will remove more than 2 pounds of waste per flush—four times that needed by the average person. List price for the model shown is $390. kohler.com
