Product Details

Kohler 3998-U-7

Wellworth toilets have been an American benchmark for style, innovation, and performance since 1936. This Wellworth high-efficiency 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 flush power. This model includes an insulated tank liner to help prevent condensation on the outside of the tank, and an elongated shape for extra comfort.
