American Standard Colony3 Two-Piece 1.28 gpf/4.8 Lpf Chair-Height Elongated Toilet Less Seat - AMS-250AA104

Yes. The Colony3 two-piece elongated bowl is built for a standard 12-inch rough-in, measured from the finished wall to the center of the closet flange bolts. That is the most common rough-in in North American construction, so on a straight replacement of an existing 12-inch installation the footprint works without moving the drain.

The Colony3 has a 16-1/2 inch rim height, which American Standard calls chair height. That is the seated height buyers specify for easier sit-and-stand in senior housing, accessible units, and multi-family turns. Note the 16-1/2 inches is the rim of the china itself, before a seat is added, and the seat is not included with the toilet.

No seat. The 250AA104 ships as bowl and tank only, and the toilet seat, wax ring, and supply line are all sold separately. Order an elongated seat to match the bowl shape. For a property manager doing multiple units, that is three line items per toilet beyond the china itself, plus closet bolts if the old set is not reusable.

1.28 gallons per flush (4.8 liters), and the Colony3 meets WaterSense criteria. That is the high-efficiency threshold utilities and green building programs look for, and it satisfies the 1.28 gpf maximum required in states like California, Texas, Georgia, and Colorado for new toilet installations.

The trapway is 2 inches and fully glazed, which is the detail that matters more than the raw size. The glazing gives waste a slick path through the bend instead of a rough cast surface for it to catch on. Paired with the 3-inch flush valve, which dumps the tank faster than a standard 2-inch valve, you get a strong flush from a 1.28 gpf tank. That combination is why this is a common spec for apartment and multi-family turns.

Two-piece is the practical call for rental and MRO work, and the Colony3 is built for it. The tank and bowl ship and handle as separate pieces, so a damaged tank is replaced on its own rather than scrapping the whole fixture, and one person can carry each half up a stairwell. One-piece units have a smoother profile and fewer seams to clean but you replace the entire fixture for any crack. The Colony3 sits in American Standard's builder line, which is where the volume specs for apartments and light commercial live.

The full manufacturer part number is 250AA104.020. The .020 suffix is American Standard's code for white, which is the finish this Colony3 configuration is built in. Distributors quoting against a spec sheet should carry the complete number with the suffix, since the base 250AA104 alone does not pin the color.

An elongated bowl projects roughly two inches further from the wall than a round-front bowl, so in a powder room where the door swing or a facing vanity is already tight, that is the dimension to check before ordering. Measure from the finished wall out to whatever is in front of the toilet. If the clearance is marginal, a round-front bowl is the better fit; the Colony3 is elongated and will not shorten to suit.

No, a color-matched trip lever is included with the toilet. It ships in white to match the china, which is the only finish the 250AA104 is offered in.
