American Standard H2Optimum Two-Piece 1.1 gpf/4.2 Lpf Standard Height Elongated Toilet Less Seat - AMS-288CA114

No seat is included. The H2Optimum two-piece elongated toilet ships less seat, so you need to order an elongated seat separately. A chrome trip lever and two color matched bolt caps are supplied with it, so those are not extra line items on the order.

1.1 gallons per flush (4.2 litres), and it meets EPA WaterSense criteria. That is well under the 1.6 gpf federal maximum, which is why it turns up on water conservation retrofits and utility rebate specs. The low volume is carried by a siphon action bowl with a direct-fed jet rather than a reduced trapway.

Standard height. The bowl rim sits at conventional seat height, not the raised ADA-style height. If you are replacing fixtures in a unit where residents have asked for an easier sit, or you are working to accessibility requirements, you want a right height / comfort height bowl instead, not this one.

Elongated bowl. An elongated bowl projects roughly two inches further from the wall than a round front, so before you swap one in, check the clearance from the front of the bowl to the door swing, the vanity, or the opposite wall of a small water closet. In tight half-baths and older apartment bathrooms that two inches is what turns a straight replacement into a returned fixture. The rough-in at the flange is unaffected.

Three things are not in the box: an elongated toilet seat, a wax ring or waxless seal, and a supply line with a stop. Closet bolts, the trip lever, and the bolt caps come with the fixture. It ships as a two-piece, so tank-to-bowl hardware is included as well and you assemble on site, which is also what makes it easier to carry up stairs than a one-piece.

Worth thinking about before you commit. The H2Optimum uses a direct-fed jet into a siphon action bowl to move waste on 1.1 gallons, which handles the bowl itself. What it cannot do is compensate for a long, flat, or partially blocked building drain that was sized around 3.5 or 5 gallon flushes. On short runs with proper fall it is a straight swap; on a long horizontal run in an older building, low-flow conversions are where drain carry complaints come from.

American Standard classifies the H2Optimum 288CA114 as a residential fixture. It suits apartments, multi-family units, and light-duty applications in hospitality or assisted living. For a heavy-traffic public restroom, a flushometer bowl with a manual or sensor flush valve is the usual specification instead, since it has no tank to vandalize and no fill valve to service.

EverClean is an antimicrobial surface fired into the china. It inhibits the growth of stain and odor causing bacteria, mold and mildew on the glazed surface, which keeps the bowl looking clean longer between services. It is not a disinfectant and it does not sanitize the fixture, so your cleaning schedule stays the same. For a property manager running turns across many units, the practical value is fewer stain complaints, not less labor.

The PowerWash rim directs flush water around the bowl to scrub it on every flush, rather than just dribbling water down the sides from rim holes. Paired with the EverClean glaze it is what keeps a 1.1 gallon flush from leaving a ring. In high-traffic restrooms that is the difference between a fixture that looks serviced and one that does not.

White only, part number 288CA114.020. The supplied bolt caps are color matched, so the trim finishes out in white as well. If you are standardizing fixtures across a building, that keeps this consistent with the standard white china already on most openings.

The sanitary bar is a raised ledge across the back of the bowl that closes off the gap between bowl and tank, so waste and cleaning residue cannot collect in a seam you cannot reach. It is a detail that matters in healthcare, assisted living, and any facility where the restroom gets inspected. On a two-piece toilet it removes the worst of the cleaning penalty against a one-piece.

Vitreous china, the standard for commercial and residential fixture china. It is a fired, non-porous glazed body, so it does not absorb water, stain, or hold odor, and it takes chemical cleaners without dulling. The EverClean antimicrobial treatment is part of that fired surface rather than a coating applied afterwards.
