|A Faucet, and I Don't Have Large Hands|
It's funny, once I started thinking about this, sink design that is, it has become more interesting. My preference is a hot and cold knob, with clearance between the spout and bowl. Simple, effective. How many times on the single knob designs do you play with it to make sure hot is still on the left and cold on the right? Half the time hot and cold sides aren't even labeled? What about those shower designs were you just rotate the knob? You don't get to choose between temperature and flow rate! Why hotels put those in is beyond me.
A hot knob and a cold knob, it's old, but it works. Sometimes we don't have to reinvent the wheel.
