The unique design of the Rêve® collection adds a sculptural element to the bathroom. With geometric lines and contemporary styling, this one-piece Rêve Comfort Height® toilet delivers a bold design along with substantial water savings. The dual-flush toilet activates with the press of a button, offering the choice of 0.8 or 1.6 gallons per flush. At the high-efficiency 0.8 gpf flush setting, you can save as much as 6,000 gallons of water annually over a traditional 1.6 gallon toilet.
