American Standard Colony3 1.28 gpf/4.8 Lpf 12-Inch Rough Lined Tank - AMS-4425A154

No. The 4425A154 is the tank only, part number 4425A154.020 in white. The bowl is sold separately, so you need to order a matching Colony3 12-inch rough-in bowl to make a complete toilet. The tank does ship with a color-matched right-hand trip lever already included.

1.28 gallons per flush (4.8 liters), which puts it in high-efficiency territory and it carries WaterSense certification. For property managers running water-conservation retrofits or working under a 1.28 gpf municipal requirement, this is the tank that meets it. It uses a 3-inch flush valve to move that smaller volume quickly.

The lining is an insulating layer inside the vitreous china that keeps the cold supply water from chilling the outside surface of the tank. In humid spaces, or any bathroom without good ventilation, an uninsulated tank sweats and drips onto the floor, which over time damages flooring and subfloor. The Colony3 4425A154 is fully lined specifically to stop that condensation. If you're replacing tanks in a gym, a coastal property, or a laundry-adjacent restroom, this is the version to spec.

Right hand. The trip lever ships installed on the right side and is color-matched to the white china. If your existing fleet of fixtures runs left-hand levers, this one won't match that orientation.

White only, ordered as 4425A154.020. The 020 suffix is American Standard's white code. For a property manager standardizing restrooms across a portfolio, white keeps the fleet consistent and makes replacement china easy to source later.

It's built as a builder-grade fixture, which is what most multi-family, spec-home, and light commercial restroom work calls for. Vitreous china wipes down easily and holds up to routine cleaning chemicals. For heavy traffic commercial applications, a flushometer setup is usually the better call than a gravity tank toilet.
