Step 1
First step is to remove the old sink. To do this you must turn the water supply off. Some sinks have shut off valves under the sink if you do not have shut off valves then you must turn the water off to the whole house. Once water is shut of proceed to remove the water supply hoses to the hot and cold water inlets of the faucet. There are different types of connections to the faucet, it may be a "thumb nut" or "wing nut", these are hand tightened and easy to remove. Or yours can be the traditional "flair nut", to remove this type of nut you will need an adjustable crescent wrench or a special pipe wrench for sinks, but more times than not a small crescent wrench is sufficient. After placing the inlet hoses to the side now remove the drain line from the sink, Channel lock pliers will most often remove this, You only need to remove the top nut connecting the "tail pipe" to the sink and the tail pipe itself. Now your sink may have anchors, these are screws underneath the sink around the area of the sink that holds the sink tight against the counter top. remove or loosen the screws and lift the sink up and out of the way. With a tape measure, measure the cut opening in the counter top. You will need to replace the sink with another the same dimensions unless you buy a larger sink and re-cut the opening to the correct dimensions. Now go buy the sink and faucet you like. But before you do so, go back to the water inlet hoses and take a look at the gaskets, do they look old and worn? It may be a good idea to go ahead and replace them now. If it has a removable rubber gasket take one with you because they come in different sizes. If they are not removable the replace the hose itself with the same type hose, again take one with you because there are several different types.

Step 2
Resetting the sink; First if no cutting to the counter top is needed then place plumbers tape around the area of the counter top the sink will set on. The plumbers putty will keep the sink in place and provide a "seal" around the sink. Now before you put your sink in the hole place your new faucet in place and tighten only the nut that holds the faucet to the sink, then place your drain fitting in the hole in the sink for your drain, some drain fixtures come with a gasket to place between the sink and the drain fixture. If no gasket is provided then again place plumbers putty around the opening in the sink where the drain fixture goes to provide a water tight seal. Press your drain fixture into the hole firmly and tighten the nut below the sink to keep the drain in place. Now that your faucet and drain are connected to the sink place sink into opening in counter top. Hopefully your sink came with new anchors, if not go back to the pluming store and by some, four will do. Or perhaps your sink is not equipped to handle anchors, if not that's ok the putty around the counter top opening will keep the sink in place. Your sink is secure.

Step 3
Now it's time to replace and reset the plumbing hard ware. Start with the water supply, did you change the gasket or hoses? tighten the supply hoses to the faucet, do not over tighten as it could strip the threads out even break the faucet connection. Now replace the tail pipe and secure the tail pipe to the drain, Your done, all that is left is to turn water back on and check for leaks.
