The downside of a single-handle faucet is that users can inadvertently mix in hot water when all they want is cold. The KWC Ava faucet has a fix for that. Instead of rotating this fixture’s lever all the way to the right to get “full cold,” the user lifts it up from the straight-ahead (6 o’clock) position, which is where it’s most likely to have been left by the previous user. For hot water you rotate the lever clockwise, as shown in the photo. The Ava has a chrome finish and retails for $650; a tall version costs $780. KWC America, 678/334-2121, kwcamerica.com.
