American Standard | Dual Flush Retrofit Compatibility

American Standard currently offers over 100 different toilet models and has produced many hundreds more over the years, all with varying tank dimensions and hardware standards.  Most of the higher profile tank models can be retrofitted with a dual flush kit, but some of the compact models may not have enough space or height inside the tank.

In determining whether a dual flush kit will fit a given model and which kit to select, the  overall tank dimensions, drain size and cutout for the flush handle or push button actuator need to be measured.

See our DIY Install tab for much more detail on toilet types, kit selection and dual flush kit installation.
