An insulating liner helps prevent condensation on the outside of the tank. Pair this tank with the K-4309 bowl for a complete toilet. 1.28 gallons per flush (gpf). Standard left-hand Polished Chrome trip lever included. Insuliner® tank liner minimizes condensation on the tank when exposed to high humidity. Supply line not included. Combines with the K-4309 bowl to create a complete K-3609-U Cimarron toilet. Coordinates with other products in the Cimarron collection. DryLock™ System saves installation time and helps prevent water leakage.
