Mansfield Plumbing has introduced Cascade, a rimless toilet that uses 1.28 gpf. As dirt and stains tend to collect under the rim, its elimination allows the toilet to stay clean longer. This is further helped by a series of holes at the top of the bowl that produce a swirling action when the trip lever is activated. The holes are visible and accessible for easy cleaning. Available in a round or elongated front model in white, Cascade is Water-Sense-certified.
