American Standard Colony3 Two-Piece 1.28 gpf/4.8 Lpf Standard Height Elongated Toilet Less Seat - AMS-250CA104

No seat is included. The Colony3 250CA104 ships as bowl and tank only, so you order the elongated seat separately. The wax ring and the supply line are also not in the box. What does come with it is a color-matched trip lever, so you are not chasing a lever finish on top of everything else. For a full install plan on a white bowl: elongated seat, wax ring or waxless gasket, closet bolts, and a supply riser.

It meets WaterSense criteria and flushes at 1.28 gpf / 4.8 Lpf. That is the number to put on a submittal where the spec or a local water ordinance calls for a high efficiency toilet rather than a 1.6 gpf fixture, and it is what qualifies the fixture under most utility rebate programs that reference WaterSense.

Standard height. The Colony3 250CA104 sits at the traditional bowl height, not the taller chair-height rim. If you are outfitting units where residents need an easier sit-to-stand, or you are chasing an ADA-referenced seat height, a standard height bowl is not the one to spec. For a mixed property, a lot of managers standardize the accessible units on a right height model and use standard height everywhere else.

The rough-in is the same 12 inches, so the flange and supply do not move, but an elongated bowl projects roughly two inches further into the room than a round front. In a tight powder room or a unit where the bowl faces a swinging door or a vanity toe kick, measure the clear floor space in front of the flange before you commit. The waste connection is identical; it is only the front of the bowl that changes.

Two things carry the flush here: a 3-inch flush valve, which dumps the tank faster than a conventional 2-inch valve, and a fully glazed 2-inch trapway that gives waste a slick path out. The wider valve is what lets a 1.28 gpf fixture move a full bowl of water quickly. For high-turnover rentals and multi-family, the glazed trapway is the part that matters most, since bare china in the trap is where buildup starts.

Builder grade. American Standard positions the Colony family as its volume line, which is why it turns up in apartment turns, spec homes, and MRO replacement work rather than in a designer bathroom package. Plain two-piece styling, no skirted trapway, no concealed trip lever. If you are standardizing a portfolio on one repeatable bowl, that plainness is the point.
