A perfect union of practicality and aesthetics, the KOHLER Reach Curv toilet features a modern design with an extended skirted trapway for a cleaner more connected design. Two top-mount buttons offer the choice of 0.8 or 1.28 gallons per flush. At the lower 0.8 flush setting, this dual-flush high-efficiency one-piece elongated toilet can save as much as 6,000 gallons of water annually over a traditional 1.6 gallon toilet.
