American Standard Cadet PRO 1.6 gpf/6.0 Lpf 12-Inch Rough Lined Tank - AMS-4188A054

The trim is part of the tank. It ships with a metal shank fill valve, a metal trip lever, and an oversized 3 inch flush valve. You will still need a supply line, tank-to-bowl bolts and gasket if your bowl kit does not include them, and of course the matching bowl, since this is a tank only.

1.6 gallons per flush (6.0 Lpf), which meets the standard low-consumption requirement. It carries a 1,000 gram MaP score at that volume, the top of the MaP scale, so the reduced volume is not costing you flush performance on heavier waste loads. That matters in multi-family and high-traffic residential where callbacks for double flushing eat the savings.

Only if your existing bowl is a Cadet PRO bowl set for a 12 inch rough. Tanks and bowls are matched sets, the bolt spacing, the tank-to-bowl gasket seat and the flush valve outlet all have to line up, so a tank from one series does not reliably drop onto a bowl from another. Check the model number stamped inside your existing tank or on the bowl against the Cadet PRO series before ordering this one.

A lined tank has an insulating liner inside the china to stop condensation forming on the outside when cold supply water meets warm humid room air. If you have had sweating tanks dripping onto the floor in bathrooms without good ventilation, or you are in a hot humid climate, the lined version is what you want. The Cadet PRO 4188A054 is the lined tank; an unlined tank of the same series will sweat under those conditions.

Three: White (4188A054.020), Bone (4188A054.021), and Linen (4188A054.222). If you are matching an existing bowl, order by the suffix rather than by eye, since Bone and Linen read close to each other in photos but are distinctly different china colors on the wall.

The tank measures 18.938 long, 10.375 wide and 16.125 high in inches. Work the 10.375 dimension against the wall for front-to-back projection of the tank body and the 16.125 for height above the bowl deck, and confirm any window sill, towel bar or shelf above the fixture clears the lid.

American Standard classifies the Cadet PRO 4188A054 as a residential fixture, and it is the trade exclusive version of the Cadet tank. Property managers use it heavily in apartments and single-family rentals for that reason, but if you are speccing for a school, stadium or similar high-abuse public restroom, you should be looking at a flushometer bowl rather than a tank type toilet.
