MANSFIELD. The 1.28-gpf rimless Cascade toilet features jets positioned to create a swirling action that cleans the toilet as it empties the bowl. The unique design keeps the unit cleaner longer by eliminating the primary place that dirt and stains collect: under the rim. The Cascade is available in round front and elongated/ADA configurations. 877.850.3060. www.mansfieldplumbing.com.
