American Standard Colony Two-Piece 1.28 gpf/4.8 Lpf Standard Height Elongated 10-Inch Rough Toilet Less Seat - AMS-221CB104

That's exactly what it's built for. The Colony 221CB104 is a 10-inch rough-in bowl, meaning the closet flange centerline sits 10 inches off the finished wall. Most homes built after the 1950s use a 12-inch rough, so measure from the finished wall (not the baseboard) to the center of the flange bolts before ordering. If that measurement comes back at 12 inches, this is the wrong bowl and you want the 12-inch rough version of the Colony instead.

Three: White (221CB104.020), Bone (221CB104.021), and Linen (221CB104.222). The bowl caps and trip lever come color-matched to the china, so a Bone or Linen unit doesn't land with white hardware on it. If you're filling in on an older building where the existing fixtures are Bone or Linen, those suffixes are the ones to order against.

Elongated bowl. A round-front seat will not cover it, so specify an elongated seat when you buy. Elongated bowls also project further into the room than round, which matters in a tight powder room or a half bath where the door swing is close.

1.28 gallons per flush (4.8 liters), and it's WaterSense certified, which is the 20 percent reduction over the 1.6 gpf federal maximum. That matters on two fronts for a property manager: it meets the 1.28 gpf requirement in jurisdictions like California and Texas that have adopted it, and it's the spec most water utility rebate programs ask for.

Standard height. The rim sits at the traditional height, not the taller chair-height dimension. For an ADA-compliant unit in a commercial or accessible unit, standard height is not the one to spec, so look to a right-height or comfort-height Colony instead.

American Standard classifies the Colony 221CB104 as a residential fixture. It's a fine fit for single-family, condo, and multi-family dwelling units, which is where most property managers install it. For a high-traffic public restroom in a school, stadium, or office core, a flushometer bowl with a 1-1/2 inch top spud is the better call than a two-piece tank toilet.

Vitreous china, the standard glazed ceramic body for plumbing fixtures. The glaze is non-porous, so it takes a scrub and a bleach-based cleaner without staining, which is the reason it's the material of choice for turnover work in rental units. The Powerwash rim on the 221CB104 scrubs the bowl on each flush, which cuts down on the ring that forms in low-use units.

Yes, and that's a common use. The Colony family runs across White, Bone, and Linen on this model, so a portfolio can be standardized on one color and one part number. Ordering by the full MPN with the color suffix (221CB104.020 for White, .021 for Bone, .222 for Linen) is what keeps the deliveries consistent unit to unit. Seats are ordered separately, so add an elongated seat to each count.
