§ FAQ

What rough-in is required for the Memoirs Stately K-3817-0?

The K-3817-0 is specified for a 12-inch rough-in. Measure from the finished wall, not the baseboard, to the center of the closet bolts to confirm the plumbing matches. This is especially important with style-forward toilets like the Memoirs line, because appearance and tank fit can both suffer if the rough-in is off.

How capable is the AquaPiston flush on this Memoirs model?

The AquaPiston flush is designed to provide a strong gravity flush while using 1.28 gallons per flush, helping the toilet stay efficient without feeling underpowered. Water exits the tank through a canister-style valve that allows rapid flow into the bowl. For most households, that means dependable everyday waste removal with less water use than older 3.5 GPF or 1.6 GPF toilets.

Can I add an aftermarket seat to this toilet since one is not included?

Yes, and that is one of the practical benefits of this package. Because no seat is bundled, you can choose an aftermarket elongated seat with the exact features you want, such as slow-close hinges, quick release hardware, or a bidet seat if the bowl geometry allows it. It is still important to confirm fitment with the elongated bowl shape and Kohler mounting dimensions before purchasing.

What does Comfort Height change for daily use?

Comfort Height raises the seat position closer to typical chair height, which many adults find easier to use than a standard-height bowl. It can reduce strain when standing up and sitting down, making it appealing for older users or anyone planning for long-term accessibility. The tradeoff is that some children may find it less comfortable without a step stool.

Is this Memoirs toilet considered water efficient and WaterSense certified?

Yes. Its 1.28 GPF rating places it in the high-efficiency category and lowers water use relative to traditional higher-volume toilets. Under the rules you provided, all 1.28 GPF products in this set are marked WaterSense certified. That gives buyers a more efficient option without giving up a full elongated bowl and classic two-piece layout.
