With its clean, simple design and efficient performance, this KOHLER® Highline water-conserving 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 chair-height ensures comfortable use.
Couldn't be happier with this toilet. The black finish is stunning, and it performs flawlessly. Kohler quality never disappoints, and it really elevates the look of the bathroom.. Debbie. Beacon, NY. Sat Oct 24 2026
