The Kohler Memoirs Stately K-6428-0 is a premium one-piece compact elongated toilet that combines classic architectural styling with a more space-conscious footprint. Its skirted trapway gives the base a cleaner built-in look and simplifies exterior cleaning, while the 1.28 GPF AquaPiston flush is designed for efficient everyday performance. Because the seat is not included, buyers can pair it with a preferred elongated seat style or upgrade.
What rough-in is required for the Memoirs Stately K-6428-0?
The K-6428-0 is designed for a standard 12-inch rough-in. Measure from the finished wall to the center of the floor bolts before ordering so the one-piece body aligns correctly with your drain location. That check matters even more with skirted toilets because the concealed sides leave less tolerance for rough-in mismatch.
How does the AquaPiston flush perform on this compact elongated model?
The AquaPiston system uses a canister-style flush valve to move water quickly from the tank into the bowl while staying at 1.28 gallons per flush. In practice, that gives this toilet a more forceful gravity flush than many older flapper-based designs. It is positioned as a high-efficiency residential toilet that still aims for solid day-to-day bulk waste performance.
What type of seat fits this toilet if one is not included?
This toilet uses a compact elongated bowl, so seat fit should be confirmed carefully rather than assuming a generic elongated seat will always match perfectly. Kohler and some aftermarket brands offer elongated seats that may work well depending on the bowl shape and mounting layout. If you want features like slow-close hinges or bidet functionality, checking the manufacturer's compatibility guidance first is the safest approach.
What does Comfort Height mean on the K-6428-0?
Comfort Height places the seating position closer to standard chair height than a traditional toilet. Many adults find that easier to use because it reduces the amount of bending required when sitting down or standing up. It is especially appealing for aging-in-place plans, although some children may prefer a lower bowl height.
Is this toilet considered water efficient and WaterSense certified?
Yes. At 1.28 GPF, the K-6428-0 uses less water than older 1.6 GPF and 3.5 GPF toilets while remaining a full-size everyday residential fixture. Under the rules for this dataset, 1.28 GPF toilets are marked WaterSense certified. That makes this model a premium-style option with efficient water use built in.
