With its clean, simple design and efficient performance, this KOHLER® Highline tall two-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 two-piece round-front toilet, without sacrificing flushing power. The round-front bowl perfectly complements smaller bathroom spaces, while the tall height offers additional comfort.
