The Sinkpositive Tank Lid ($99) is a sink that sits on your toilet tank and routes water through its tap before using to refill your toilet after it's flushed. Yes, it cuts down on water usage by making the future toilet water do double duty, but it's still a little too close to the hopper for our comfort. If you're more enviro-friendly than us, you can also get a deluxe version for $119.
