Enhance your bathroom space with this redesigned KOHLER Highline two-piece elongated toilet. With our most powerful flush built into one of our most popular toilet designs, the upgraded Highline toilet combines trusted performance with top-of-the-line features to enhance luxury and efficiency. At the heart of this toilet's clean and simple aesthetic is Revolution 360 technology, an advanced flushing system that uses a powerful swirling motion to thoroughly rinse the bowl. A 1.0 Gal. flush reduces water use by more than 35% over 1.6 Gal. toilets, offering a water savings of more than 4,500 Gal. of water per toilet, per year. Weighing less than previous Highline models, this toilet is easier to handle and install. Color: Black. Material: Vitreous China.
