  1. Purchase a drain kit and plumbers putty from your local hardware store. This is pretty much all that is necessary to install bathroom sink drain. Disconnect the pipe under the sink, from the sink drain. Use a monkey wrench or just a pair of pliers to loosen and remove the nut and gasket that keeps the sink drain in place.

  2. Remove old sink drain from sink. Before installing new drain, apply the plumbers putty around the sink opening (flange); this will help to set the drain and prevent leakage, then drop the sink drain in and put a little force on it to set it into the plumber’s putty, clean up excessive putty. You can allow the putty to strengthen a bit around the drain, but it’s not required.
