Read our Reviews

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 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-4309 bowl for a complete toilet.
