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. Pair this tank with the K-5309 bowl for a complete Cimarron skirted toilet.

Best Price!

Would Recommend

Exactly as described and arrived in perfect condition! It had the black canister and flush valve in it, too; I didn't expect that!

Was this Review Helpful ?

Well packed in the box. No cracks or issues.

Would Recommend

It came well packed and without cracks. I bought this tank from the competition 3 times, and 3 times I had to return it because it was broken. At Lowe’s it only took one time to buy it.

Whooshing sound when flushing

Would Not Recommend

Not a quiet toilet. When you flush, it makes this whoosh sound that can be heard two rooms away. Not sure which Kohler part is really responsible for the noise (tank, flush mechanism, bottom) so maybe the tank is ok.
