The Profile Smart with integrated rinse station from Caroma is a high efficiency dual flush toilet that averages just 0.9 gallons per flush. This clever system directs fresh water through the integrated faucet for hand washing. This water then drains into the tank for the next flush. The Profile Smart features 1.28 gallons per flush for solid waste and 0.8 gallons per flush for liquid/paper waste, WaterSense labeling, and the large trapway virtually eliminates blockages. The Profile Smart has two models: the Easy Height Elongated and Round Front Plus.
