American Standard Boulevard One-Piece 1.28 gpf/4.8 Lpf Chair Height Right-Hand Trip Lever Elongated Toilet With Seat - AMS-2891813

The bowl has a 16-1/2 inch (419 mm) rim height, which American Standard calls Chair Height and lists for accessible applications. That is rim height before the seat, so the finished seat height lands slightly higher. It is the comfort-height range most property managers and senior housing specs ask for over a standard 14 to 15 inch bowl.

It flushes at 1.28 gpf (4.8 Lpf), 20 percent less than a 1.6 gallon fixture, and meets EPA WaterSense criteria. That is the qualification most municipal and utility water-conservation programs reference, and it satisfies jurisdictions that mandate high-efficiency toilets on new work.

The seat is included. It ships with a slow-close seat and cover with a concealed seat ring and an easy lift-off feature for cleaning, plus two color-matched bolt hole covers. No separate seat purchase and no extra trim to source.

Right-hand trip lever. Worth checking against the layout, because in a tight water closet with the fixture set close to a side wall or vanity, a right-hand lever can end up buried. American Standard builds left-hand trip lever versions of Boulevard bowls under separate model numbers.

A one-piece has no tank-to-bowl joint, so there is no tank gasket or tank bolts to weep, and the outside is a continuous surface with no seam to trap grime, which is why maintenance crews favor them. The tradeoff: a one-piece is heavier to set and, if the china cracks, you replace the whole fixture rather than just a tank. Two-piece bowls are easier for a single installer to handle up stairs.

The bowl uses a 2 inch (51 mm) fully glazed, smooth-sided concealed trapway fed by a 3 inch (76 mm) flush valve. The large valve dumps the tank fast for a strong siphon, and the PowerWash rim directs water around the bowl on every flush to scrub it. Concealed trapway also means no external casting ribs to wipe around.

This Boulevard model is elongated, which adds roughly two inches of bowl projection over a round front and is the standard for commercial and accessible restrooms. In a powder room or a stall where the door swing or the clear floor space is tight, measure the projection from the wall before committing; a round front is the fallback when you cannot give up the depth.

EverClean is an antimicrobial surface fired into the china that inhibits the growth of stain- and odor-causing bacteria, mold and mildew on the glazed surface. It slows staining between cleanings in high-traffic restrooms, but it is not a sanitizer and does not remove the need for routine cleaning.
