Fitting basics and faucet
“fittings” is the technical term for all faucets, spouts, spigots, handles, tub fillers, and other hardware that move water to and away from a fixture. Lower spouts, whether straight or curved, offer an increased rush of water but less clearance, and so require deeper bowls. To avoid splashes, make sure the spout is log enough to overhang the rim of the basin and pour directly into the drain.
