With its clean, simple design and efficient performance, this KOHLER® Highline one-piece toilet combines both style and function. An innovative 1.28-gallon flush setting provides significant water savings of up to 16,500 gallons per year, compared to an old 3.5-gallon one-piece elongated toilet, without sacrificing flushing power. The elongated Quiet-Close™ seat and chair-height ensure comfortable use.
