This toilet tank combines water efficiency with the versatile style of the Cimarron collection. A 1.28-gallon flush provides significant water savings of up to 16,500 gallons per year, compared to a 3.5-gallon toilet, without sacrificing performance. This tank features innovative AquaPiston(R) technology, a patented flush engine that delivers a fast, powerful, and virtually plug-free flush. An insulating liner helps prevent condensation on the outside of the tank. Pair this tank with the K-4829 or K-4347 bowl for a unified look.

  • Left-hand Polished Chrome trip lever.
  • Insuliner tank liner minimizes condensation on the tank when exposed to high humidity.
  • Combines with the K-4347 or K-4829 bowl to create a complete K-3887 or K-3851 Cimarron toilet.
