This Cimarron toilet tank features innovative AquaPiston technology, a patented flush engine that delivers a fast, powerful, and virtually plug-free flush. 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. Pair this tank with the K-31588 bowl for a complete Cimarron K-31621 elongated toilet.


  • 1.28 gpf (4.8 lpf)
  • Left-hand Polished Chrome trip lever
  • Combines with the K-31588 bowl to create a complete K-31621 Cimarron elongated toilet
  • AquaPiston canister optimizes the flow out of the tank, harnessing gravity and the natural, powerful reducing cascade of water to increase the power and effectiveness of the flush
  • Easy-to-flush canister design requires less force to actuate than a 3" (76 mm) flapper, and has 90% less exposed seal material which resists conditions that cause wear, tear, shrinkage and swelling
