The 1.28-gallon-per-flush Sydney Smart 305 round-front toilet can save the average U.S. household up to 5,242 gallons per year compared with a standard low-flow toilet, claims manufacturer Caroma.

The toilet, which carries the EPA’s WaterSense label, has dual flush buttons, located on top of the tank, in lieu of the typical lever. You push one button to eliminate liquids and paper, the other to flush solids. Despite its miserly water consumption, the toilet is designed to be clog-proof according to the manufacturer, thanks to a trapway that is nearly twice as wide as the industry average.

The Sydney Smart, $349 in white (also available in biscuit), is backed by a two-year warranty and is sold at bath showrooms and plumbing-supply dealers.—Kimberly Janeway
