No matter what type of sink you purchase, the drain and water-supply connections are generally installed in the same way. Hand-tighten a female adapter onto the drain stub-out at the wall. Slide slip nuts onto the drain arm and the sink's tailpiece. Fit a P-trap in place and tighten the slip nuts by hand. Connect flexible water-supply tubes onto the faucet's tailpieces, and route them to the shut-off valves. Tighten coupling nuts with an adjustable wrench. Remove the faucet aerator, turn on the water, check for leaks at the shutoff valves, and then turn on the faucet to check for leaks in the drain assembly. Replace the aerator.
