First of all, let me just say that we here at homeiq love Caroma, an Australian company that introduced American consumers to water-saving dual-flush toilets. But we’re not sure about one of their latest creations: the Profile Smart high-efficiency toilet that incorporates a sink into the lid of the toilet tank. As a water-saving design, the Water Sense certified unit is ingenious. A user washes his hands—hopefully!—and the water he uses drains into the tank to be used for the next flush. On top of that, the toilet uses 1.28 gallons of water for a full flush—as opposed to the standard 1.6 gallons per—and 0.8 gallons per flush for a half flush. We like the idea, but we dislike the design. It’s hard to really wash your hands because of the limited space, plus the sink is a little small. Hopefully, Caroma will improve the design in the years to come. www.caromausa.com.
