American Standard H2Optimum Two-Piece 1.1 gpf/4.2 Lpf Standard Height Round Front Toilet Less Seat - AMS-288DA114

No seat is included. The H2Optimum 288DA114 ships less seat, so you need to order a round front seat separately. A chrome trip lever and two color matched bolt caps are supplied with the bowl and tank, so those are the only trim pieces you don't have to source.

The H2Optimum 288DA114 is a round front bowl, which projects less from the wall than an elongated bowl. Swapping an elongated toilet for this one leaves you extra clearance, not less, so it works in tight half baths and narrow stalls where an elongated bowl crowds the door. Going the other direction (round to elongated) is where you run out of room. This is a standard height two-piece, so seat height matches a conventional bowl rather than a comfort height one.

1.1 gallons per flush (4.2 liters), and it meets EPA WaterSense criteria. That is well under the 1.6 gpf federal maximum and below the common 1.28 gpf high-efficiency figure, which is what makes it a candidate for water rebate programs and for retrofit programs in multi-family where flush volume drives the payback.

The H2Optimum bowl is MaP PREMIUM listed, which is the highest MaP performance tier and the number specifiers look at when they are nervous about a low-volume flush. It uses a siphon action bowl with a direct-fed jet and a PowerWash rim that scrubs the bowl on each flush. For property managers replacing older 1.6 or 3.5 gallon fixtures across a building, that MaP listing is the evidence that the 1.1 gpf volume is not a callback waiting to happen.

It is classified residential. For apartments, condos, single family rentals and the residential side of mixed-use it is the right call. If you are speccing for a high-traffic public restroom, a school, or a stadium, look at a flushometer bowl with a commercial-duty rating instead of a residential tank type toilet.

EverClean is an antimicrobial treatment fired into the china surface that inhibits growth of stain and odor causing bacteria, mold and mildew on the surface itself. It cuts how fast the bowl stains between cleanings, which is why it shows up in rental turnovers and low-frequency-service buildings. It does not sanitize the water and it is not a substitute for routine cleaning.

Two-piece: tank and bowl ship separately and bolt together on site. That matters on stair carries and elevator jobs where a one-piece unit is heavy and awkward for one person, and it means a cracked tank later is a tank replacement rather than a whole fixture. The bowl carries a sanitary bar, and the china is vitreous, so it takes standard bowl-to-tank and closet bolt hardware handling.
