American Standard Colony Two-Piece 1.28 gpf/4.8 Lpf Standard Height Round Front 10-Inch Rough Toilet Less Seat - AMS-221DB104

Yes, the Colony 221DB104 is built specifically for a 10-inch rough-in, meaning the closet flange centerline sits 10 inches off the finished wall. If your waste line measures the standard 12 inches, this is the wrong bowl and you want the 12-inch rough-in version of the Colony instead. Measure wall to the center of the flange bolts before ordering, not to the baseboard.

Standard height. The Colony 221DB104 sits at the traditional bowl height, which is lower than the chair-height or comfort-height bowls that ADA guidance points to for accessible stalls. For apartment turns and residential bathrooms that is usually what you want. If you are specifying for accessibility, you need a right-height model, not this one.

Beyond the bowl and tank you need a round front seat, which is not included, plus the usual set-out parts: a wax ring or waxless seal, closet bolts, and a supply line to the fill valve. The bowl caps and trip lever come color-matched in the box, so those are not add-ons. If the old flange is corroded or sits below the finished floor, add a repair flange or spacer while you have the fixture up.

Two: Bone (221DB104.021) and Linen (221DB104.222). Both are the same 10-inch rough-in, round front, 1.28 gpf bowl, so the choice is purely matching the china to the rest of the washroom. If you are replacing one fixture in a room of older American Standard china, hold a cap or the tank lid against a sample before you commit, since Bone and Linen read close in photos and apart in daylight.

1.28 gallons per flush (4.8 liters), and it is WaterSense certified, which puts it about 20 percent below the 1.6 gpf federal baseline. That matters on two fronts: it qualifies where a local code or a utility rebate program requires a WaterSense fixture, and across a building of fixtures the per-flush difference adds up on the water bill. The PowerWash rim directs the flush around the bowl so the reduced volume still scours.

That is exactly what the round front bowl is for. A round front projects less into the room than an elongated bowl, which is why it is the usual pick for powder rooms, closet-sized baths and tight apartment layouts. Pair that with the 10-inch rough-in and the 221DB104 suits older or shallow bathroom footprints where a 12-inch rough elongated bowl would crowd the door swing.

For the units with a 10-inch rough, yes, and that is the value of keeping this model on the shelf. The Colony family runs the same bowl style across rough-in dimensions, so you can spec Colony throughout and just change the rough-in per unit while the look, the trip lever and the cap color stay consistent. Order the 221DB104 only for the 10-inch openings; putting it on a 12-inch waste line leaves a two-inch gap behind the tank.

Two-piece: the tank bolts to the bowl on site. For a property manager or a contractor doing turns that is usually the easier fixture to handle, since the two halves carry up a stairwell separately and a cracked tank can be replaced without pulling the whole bowl. A one-piece has fewer seams to clean but goes in as one heavy unit.
