Dual-flush Toilet Collection

American Standard has released the Studio and Boulevard dual-flush toilets. They use 1.6 gallons per flush for solids and 1.1 gallons per flush for liquids, which is 20 percent less water than standard models. The Studio models have an elongated round front and the Boulevard collection is a one-piece, elongated model. Both have a finish that inhibits the growth of stains, bacteria, mold and mildew.
