American Standard Colony 1.28 gpf/4.8 Lpf 10-Inch Rough Tank - AMS-4192B104

Tank only. The 4192B104 is the vitreous china tank half of a two piece Colony toilet, and it ships with a color matched trip lever. You order the matching Colony 10 inch rough bowl separately, plus a wax ring and closet bolts for the floor set. Buy the tank alone when you're replacing a cracked lid-to-floor tank and the bowl is sound.

Only pair this tank with a Colony bowl designed for it. A 1.28 gpf tank moves 20 percent less water than a 1.6 gpf tank, and an older bowl engineered around the larger volume can be sluggish or need a second flush. The 9 x 8 inch water surface and 2 inch flush valve are matched to the current Colony bowl, so replace the tank as part of that pairing rather than dropping it on whatever bowl is on the floor.

Three: White (4192B104.020), Bone (4192B104.021), and Linen (4192B104.222). The trip lever ships color matched to the tank, so a Bone tank arrives with a Bone lever. Match the suffix on your existing bowl, since American Standard uses the same color suffixes across the Colony line and a White tank on a Linen bowl is an obvious mismatch.

The tank measures 18.375 x 14.313 x 8.25 inches. In a tight powder room or a commercial stall, check the 18.375 inch figure against the clear width you have and the 14.313 inch figure against anything above the tank, a window sill, a towel bar, or a vanity return that would block the lid coming off for service.

The Colony 4192B104 is a residential grade tank. It suits apartments, condos, single family rental units, and hospitality guest baths. For high traffic public restrooms, a school, an airport, or a stadium, spec a flushometer bowl with a manual or sensor flush valve instead of a tank type toilet, since the tank refill cycle limits how fast back-to-back flushes can run.
