American Standard H2Option Two-Piece Dual Flush 1.28 gpf/4.8 Lpf and 0.92 gpf/3.5 Lpf Standard Height Round Front Toilet With Liner Less Seat - AMS-2889518

No seat. The H2Option 2889518 is sold less seat, so you order a round front seat separately to finish the install. It's a two-piece toilet, so the tank and bowl ship together with the flush valve and the chrome plated top mounted push button actuator already part of the package.

Round front. That's the shorter of the two bowl shapes and it's what you want in a tight half bath or a apartment bathroom where the bowl projection into the room matters. If the existing fixture is elongated, swapping to this round front bowl will leave you with a shorter bowl than what came out.

Two flush volumes off one push button actuator: 0.92 gpf (3.5 Lpf) for liquid waste and 1.28 gpf (4.8 Lpf) for solids. The button sits on top of the tank, chrome plated, so a tenant picks the volume at the moment of use rather than the fixture running one fixed volume every time.

It's listed as meeting EPA WaterSense and MaP PREMIUM criteria as an Ultra-High Efficiency Toilet, which is the pairing most municipal and utility water conservation programs ask for. For a property manager doing a multi-unit retrofit, that's the documentation line to submit: UHET, WaterSense, MaP PREMIUM, 1.28 gpf full flush.

Standard height. The bowl rim sits lower than a chair height or comfort height fixture, so if you're matching an ADA or right height installation elsewhere in the building this is not the one to order. Standard height is the traditional residential rim height and is what most older bathrooms already have.

It's an insulating liner inside the tank. Cold supply water in an uninsulated china tank makes the outside sweat in humid conditions, and that condensation drips onto the floor and rots subfloor or stains ceilings below. The lined tank version is what you spec for bathrooms without good ventilation, coastal and southern climates, or any unit where a wet floor turns into a callback.

The bowl uses siphon jet flush action with a PowerWash rim, and the fixture carries a MaP PREMIUM rating, which is the bulk removal test buyers use to judge whether a low volume toilet actually clears. The 0.92 gpf setting is the reduced flush for liquids; the full 1.28 gpf is the solids flush. On a long horizontal run or an old building drain with sag, use the full flush button as the working volume and treat 0.92 as the bonus.

Beyond the toilet itself you'll need a round front seat, since none is included. Standard rough-in consumables apply too: a wax or waxless closet gasket, closet bolts, and a supply riser to the fill valve. The tank, bowl, flush valve and push button actuator all come with the fixture.

A dual flush like the H2Option gives you 0.92 gpf on the light flush and 1.28 gpf on the full flush, so the water savings depend on tenants using the button correctly. Where users are transient or won't be trained, a single flush 1.28 gpf fixture delivers the same full volume every time with one fewer moving part in the tank. Where you control occupancy and want the lowest metered water bill, the dual flush is the one that gets you below 1.28 on average.

EverClean is a surface treatment fired into the china that inhibits the growth of stain and odor causing bacteria, mold and mildew on the glaze. It's included on the 2889518. It doesn't change your cleaning routine, it just slows how fast the bowl discolors between cleanings, which is the argument for it in high traffic restrooms and rental turnovers.
