Okay, we're nuts for fancy plumbing, but this is getting just crazy. Forget filling up the sink with water — this Abisko Washbasin from Eumar is more water flume than sink. Turn on the faucet, and the water flows all the way down its undulating shape, ending up draining through a strategically placed grate.
As you'll see in the gallery below, there's also a version that turns the mini-river you create into a waterfall. We'd like to see something in between, turning your wastewater into whitewater rapids. No pricing info was available, but this is cool enough to sacrifice a bit of money down the drain.
