- Water runs from the center area of the faucet, below the handle, but above the glass, forming a beautiful waterfall off the 7 1/8″ diameter glass spout. The spout is crystal-clear glass with a 1/2″ bevel. Pop-up drains as well as sink hole covers (deck plates) are sold separately in our store. One of these would be needed, for example, if you wanted to mount a single-hole faucet into countertop with three holes; you would use a cover to hide the extra two holes.
