Shut off the water supply to the bathroom sink. If you cannot find a shutoff valve on each of the water feed pipes under the sink, then you will need to shut off the water to the entire house. The shutoff valve for the house can be found on the feed pipe in the basement just as it leads to the bathroom sink, or it is located near the water meter on the pipe that comes in from the city water supply.
Remove the flexible feed pipes that run from the water source in the wall up to the faucet in the sink. There will be connections at each end of each pipe that you should be able to turn by hand. If you cannot turn them by hand, then use a pair of locking grips to turn the connections.
Reach under the faucet assembly and remove the large nuts that are holding the assembly in place from under the sink. These nuts are normally found threaded around the base of each faucet. If they do not move by hand, then use a plumber's wrench to turn them. Detach the drain lift lever from the drain stop where they meet under the sink.
Remove the faucet assembly.
Remove the p-trap assembly that connects the drain to the wall. To do this, unscrew the connections at each end of the pipe. If these connections cannot be moved by hand, then use a plumber's wrench to move them.
Check to see if there is any caulk between the sink and the vanity counter top. If there is caulk, then run a utility knife along the caulk to cut it and free the sink from the counter.
Remove the sink from the vanity.
