About This Product

At Kohler, we push flushing power and toilet design to the leading edge. KOHLER® Wellworth toilets have been an American benchmark for style, innovation, and performance since 1936. This Wellworth high-efficiency two-piece elongated toilet delivers significant water savings with a 1.28-gallon flush setting that saves up to 16,500 gallons per year, compared to an old 3.5-gallon toilet, without sacrificing performance.

Handsome toilet that uses very little water when flushing. Tank refilling is a bit louder than others.
