American Standard’s Studio dual-flush toilets offer users the choice between 1.6 gpf for solids or 1.1 gpf for liquids. The models — elongated and round front, both in the 16 1/2” Right Height rim configuration — use a concealed trapway styling. The two-button chrome actuator on top of the tank allows the choice of the appropriate flush. Using PowerWash Rim technology, these toilets can flush as much as 1,000 grams of solid waste. The EverClean antimicrobial surface inhibits the growth of stain and odor causing bacteria, mold and mildew.
