The Kohler Memoirs Stately ContinuousClean ST Two-Piece Elongated Toilet, 1.28 GPF (model K-33817), is a premium fixture that marries elegant design with advanced technology. Part of Kohler’s Memoirs collection, it offers water efficiency, automated cleaning, and timeless style, making it a compelling choice for discerning homeowners. In this expanded review, we’ll cover its description, key characteristics, pros and cons, practical tips, additional insights, and include user-inspired feedback crafted in my own words to reflect real-world experiences.
Description
The Memoirs Stately ContinuousClean ST is a two-piece toilet with a separate tank and bowl, designed for easy installation and a classic look. Its Stately aesthetic features sharp, architectural lines that elevate bathroom décor, available in white (with Biscuit, Dune, or other colors in variants). Made from vitreous china, it promises durability and a glossy finish that resists wear.
This model shines with its ContinuousClean ST system, which uses standard white cleaning tablets to release a cleaning solution with each 1.28 GPF flush, keeping the bowl fresh for up to six months per tablet. The AquaPiston canister flush technology enhances performance by delivering water from all angles, ensuring a powerful, clog-free clean. With an elongated bowl and Comfort Height (17–19 inches, ADA compliant), it prioritizes comfort and accessibility. The polished chrome left-hand trip lever adds a refined touch, though the seat is sold separately for customization.
