Réservoir Cimarron 1,28 GPF K-4166-G9

Good quality. Had to purchase the tank separate from the bowl, but all worked out and works great! Very happy with new Kohler toilet and tank! Flushes great and uses very little water, I think we can put our plunger in the garbage!

It’s exactly what we needed to replace our cracked tank of the same make and model. P

We had purchased from Kohlers the no touch tank, which we had issues with. So we purchased this tank to replace the other one and it fit on easily.

I had originally ordered the larger size tank, which is what I wanted. However, Wayfair cancelled it without letting me know the reason. When I called, they told me it was because I live in California and the water regulations here didn't allow me to get the larger tank. However, I am very happy with the product itself. It has a strong flush and there haven't been any issues at all with the flushing. The only reason I didn't give it 5 stars is because I wasn't informed on the description it could not be ordered for California (or if it was there, it wasn't obvious).
