Picking a faucet is not just about looks -- buy the wrong one and it either will not fit your sink at all, splashes water everywhere, or starts dripping within a year. We see all three mistakes regularly. The faucet has to match your hole count, mount type, and sink dimensions. The valve technology inside determines whether it drips. And the finish needs to hold up to daily use, not just look good in the showroom. Whether you are replacing a worn-out faucet or picking one for new construction, here is what actually matters.
