American Standard Colony Two-Piece 1.6 gpf/6.0 Lpf Standard Height Elongated Toilet Less Seat - AMS-221CA004

Standard height. The Colony two-piece elongated bowl is a standard height fixture, which seats lower than the taller chair-height bowls builders often spec for accessibility. If you are matching existing standard height bowls across a building, this keeps the rim consistent. If a unit needs a taller seat for an aging resident, look at a right height or comfort height elongated bowl instead.

Two colors, both off-whites: Bone (MPN 221CA004.021) and Linen (221CA004.222). The bowl caps and trip lever are color matched to the bowl, so the visible trim follows whichever you pick. If you are patching into an existing washroom, order the color that matches the lavatory rather than guessing, since Bone and Linen do not read the same against a white tub or sink.

1.6 gallons per flush, 6.0 litres. That is the full federal maximum rather than a high-efficiency 1.28 gpf bowl, which matters two ways: it moves waste through older, flatter drain lines that were built for higher volume, and it will not qualify for utility rebate programs that require a HET fixture. On a straight like-for-like replacement of a 1.6 gpf bowl, consumption stays where it was.

Two-piece: tank and bowl ship and set separately, joined with a tank-to-bowl kit on site. That is the practical choice for upper-floor apartments and tight bathrooms, since one person can carry each half up a stairwell, and if a tank cracks you replace the tank instead of the whole fixture. A one-piece is a single cast unit, easier to wipe down at the seam but heavier and a full write-off if either half fails.

Residential duty. The Colony is a tank-type gravity bowl built for homes and multi-family units, not for a high-traffic commercial washroom where a flushometer bowl on a 1-inch supply is the usual spec. It is a fit for apartments, condos, and single-family turns. For a school, an airport, or a stadium restroom, a flush valve bowl is the right family to shop.

An elongated bowl runs roughly two inches longer front to back than a round front, so in a powder room where the bowl faces a door swing or a vanity it can be the difference between comfortable and cramped. The Colony 221CA004 is elongated only, so if the rough opening is tight, shop a round front Colony bowl instead. Where clearance is not the constraint, elongated is what most residents prefer and what standardizes best across a building.

It is a reasonable fleet fixture: one model, 12-inch rough-in, standard height, elongated, in two off-white colors, so every unit gets the same bowl and your maintenance tech stocks one trip lever and one seat size. The two things to settle before you commit the order are that every opening actually measures 12 inches to the flange centerline, and that you have a matching seat count, since the toilet ships less seat.

Vitreous china, the glazed ceramic used for nearly all tank-type fixtures. The glaze is non-porous, so it does not stain or absorb odor and it takes normal cleaners without dulling. The flush uses a PowerWash rim that pushes water around the bowl on every flush to scrub the surface, which is the part that matters in a rental where cleaning frequency is out of your hands.
