Multitasking Toilet. The Profile Smart Toilet conserves space as well as water, says the manufacturer. Intake water runs through a top-mounted faucet (for hand-washing) before flowing down the sink drain to fill up the tank. Two models are available: the standard-sized Profile Smart 305 and — for universal design applications — the Profile Smart 270, with an elevated (17-inch-high) elongated seat. Both are sold in white only and offer dual-flush (1.28 or 0.8 gpf) capability. They cost $800. Caroma USA, 800/605-4218, caromausa.com
