Key Features of the KOHLER Memoirs Toilet

Material and Design

This two-piece toilet is made of vitreous china that makes it durable and easy to clean. It has an elongated bowl for enhanced comfort as well as a comfort height that makes sitting and standing easier, even for tall people, the elderly, and the handicapped.

This ADA (American with Disabilities Act)-compliant toilet’s clear and detailed lines enhance its design. The canister is durable with rounded edges for easy cleaning. It has an effective seal, too, that reduces the possibility of leakages. The seal is durable because it’s never exposed to the tank water.

Flushing Technology

The Memoirs toilet uses the Class Five flushing technology (the bulk flushing system), a powerful system that uses less amount of water yet works efficiently and effectively with each flush.

It has a large flush valve, which paves the way for complete and quick disposal of solid wastes. To maintain the cleanliness of the toilet, the bowl releases the water from all sides. Its large trapway is 2 1/8 inches to allow for quick passage of waste with less tendency to clog.

Water Consumption

This toilet, like any other KOHLER toilets, is a water saver. It only uses 1.28 GPF (gallons of water per flush), way less than the standard 1.6 GPF. The reduced amount of water per flush is reflected on your lower utility bills and has earned it an EPA (Environmental Protection Agency) WaterSense certification.

Despite the low water consumption, you only need to flush once as it uses an AquaPiston Flush Technology. The Memoirs toilet is eco-friendly because you preserve the most vital resource in the world, water.

To further save water, move your lever halfway for a half-flush when flushing liquid wastes.

Overall Quality

The toilet is made using stainless material and vitreous enamel coating for the perfect finishing. It comes in 6 other colors aside from the usual white. It also has an AquaPiston conventional valve to aid its flush instead of the regular flippers. Its comfort height makes it a comfortable toilet to use even for tall people, the elderly, and the handicapped.

With the high pressure and low volume of water, the toilet only needs to be flushed once. Its price is above average, yes, but the quality and design of this KOHLER toilet make it worth the price.

There are many things we like about this toilet. Yet, there are some negative aspects of this toilet. Here are some of them:


  • It has a traditional and elegant design which will suit most bathrooms.
  • It has a sturdy construction, which makes it durable.
  • Its major benefit is being a water saver. You will save money from reduced water bills while also helping to conserve water.
  • Its power flush makes it easy to clean and maintain. There is a reduced need for maintenance because clogging is uncommon.
  • It has a comfortable height that may be used by people of all ages. Sitting and standing are easy with this toilet.
  • Its elongated bowl further enhances the user’s comfort, and the canister is leak-proof because it is seal protected.
  • Its Class Five flushing technology is one of a kind. Together with the AquaPiston canister, the toilet has a very powerful flush. Aside from just flushing wastes, the power flushing also cleanses the bowl.
  • It has a standard left-hand lever that works with a single flush. It can even be pushed halfway to produce a half-flush for liquid wastes. This lever makes it easy to use, even for children.


  • You have to buy the seat and supply line because they not included in the package. This increases the total cost of the toilet.
  • The toilet flapper is weak and mostly lasts less than a year.
  • Some customers complain that it flushes louder than standard toilets. This is a result of the AquaPiston cistern pressure.
  • Some people complain that it doesn’t flush well. Always ensure your cistern water level is reached and then give it a nice single power flush.
