§ FAQ

What rough-in does the Cimarron K-3619-0 need?

The K-3619-0 is designed for a 12-inch rough-in. Measure from the finished wall to the center of the closet bolts before ordering so the one-piece base and concealed trapway line up properly. That is a quick check that can prevent a difficult install.

How does the AquaPiston flush perform on this one-piece Cimarron?

AquaPiston uses a canister-style flush valve that helps release water quickly into the bowl for a strong gravity flush. At 1.28 gallons per flush, this toilet is meant to reduce water use without feeling like a low-performance economy model. For most homes, it should be viewed as an efficient full-time primary-bathroom toilet.

Does the included seat limit compatibility or upgrades?

The toilet includes a Quiet-Close seat, so it is ready to use without adding another purchase. If you want a different seat later, you can still check for compatible elongated replacements depending on the features you want. The included seat mainly adds convenience and soft-close functionality out of the box.

What is the advantage of Comfort Height on this toilet?

Comfort Height gives the toilet a more chair-like seating position than a standard-height bowl. Many adults prefer that because it can be easier on the knees and hips during daily use. It is often a good fit for primary bathrooms, guest bathrooms used by older adults, and homes thinking ahead about accessibility.

Is the K-3619-0 considered water efficient?

Yes. Its 1.28 GPF rating cuts water use relative to older 1.6 GPF and higher-volume toilets. Under the rules for this dataset, all 1.28 GPF toilets are marked WaterSense certified. That means this one-piece Cimarron combines premium construction with efficient water use.
