This outdated bathroom is getting fixed up, and I decided to do it myself, gaining experience and saving money. Taking out the sink and vanity was very difficult, so this instructable is to help any other do-it-yourself home improver's.
Step 1: You Will Need...
Tools you need...
-screw driver or electric dril
Tools you may want...
-Hammer and Chisel
Step 2: Shut Off Water
First, you need to shut off the water. This is important, unless you want your bathroom full of water. To shut off the water, there should be a knob (right tight = no water, left loose = water flowing). On most sinks there are two. Both need to be off.
Next, disconnect the hose from the shut off valve. It will be connected by a nut, a crescent wrench works well for this.
If the valve leaks it is probably time to replace it. Also. if one leaks, the other will most likely start to leak soon too, so it's best to replace both.
To replace the valve you first need find the main water valve that shuts off the water to your entire house. The second picture below shows my house's valve.
Now, all you have to do is unscrew the nut and take the old valve to your local hardware store to find a new one. Either you'll be able to tell or a hardware store employee will be able to tell you which one is correct. You'll also need to buy plumber's tape.
To install wrap the tape twice around the threads of the pipe and screw on the valve. Now, you can turn on your house's water.
Step 3: Disconnecting the Drain
To prevent a large puddle, place a bucket under the drain pipe.
Now, unscrew the nut at either end of the catch pipe.
There will a "drain assembly" that needs to be disassembled. There is a screw that needs to be loosened, and then the plug can be removed. (The second picture)
Step 4: Removing the Sink
First, cut away any caulk around the sink.
Then, remove the screws and brackets from under the sink. Be careful because the sink will fall through.
Step 5: Removing the Vanity
Start by unscrewing every screw in sight.
If the vanity doesn't fall apart, use a hammer or pry bar to tear it apart.
