Bought a house recently with these with two Kraus Square Vessel 16" Ceramic Bathroom Sink in White w/ Pop-Up Drain in Satin Nickel installed. After several months of use we've come to the conclusion that these are horribly designed and only for looks not for use. Regardless of what flow you set the faucet to these splash on you and the surrounding surfaces and the the water draining from them is the LOUDEST I've ever heard out of a domestic sink. 

So if you want something that looks nice and is eye-catching but is incredibly impractical for daily or even occasional use then this is the sink for you - but if you actually plan on using your sink find something else.
