### Tools and Materials You’ll Need
* Adjustable wrench

* Garbage disposal (optional)
* Dishwasher hose (optional)

### Step-by-Step Instructions
**1. Turn off the water supply.**
The first step is to turn off the water supply to your kitchen sink. This is typically done by turning off the valves located under the sink. If you don’t know where the valves are, you can consult your home’s plumbing diagram.
**2. Disconnect the old sink.**
Once the water supply is turned off, you can begin disconnecting the old sink. Start by disconnecting the water supply lines from the faucet. Then, use a basin wrench to loosen the nuts that hold the sink in place. Once the nuts are loose, you can remove the sink from the countertop.
**3. Clean the countertop.**
Before installing the new sink, it’s important to clean the countertop. This will help to ensure that the new sink is properly sealed and will not leak. Use a damp cloth to wipe down the countertop and remove any dirt or debris.
**4. Apply plumber’s putty.**
Plumber’s putty is a type of sealant that is used to create a watertight seal between the sink and the countertop. Apply a bead of plumber’s putty around the rim of the sink.
**5. Set the sink in place.**
Once the plumber’s putty is in place, you can set the sink in place on the countertop. Press down on the sink to create a seal between the putty and the countertop.
**6. Tighten the nuts.**
Once the sink is in place, you can tighten the nuts that hold it in place. Use a basin wrench to tighten the nuts until they are snug. Do not overtighten the nuts, as this could damage the sink or the countertop.
**7. Connect the water supply lines.**
Once the sink is secured in place, you can connect the water supply lines to the faucet. Use Teflon tape to wrap the threads of the water supply lines before connecting them to the faucet. This will help to create a watertight seal.
**8. Connect the drainpipe.**
If you are installing a new drainpipe, you will need to connect it to the sink. Use a hacksaw to cut the drainpipe to the desired length. Then, apply a bead of plumber’s putty to the end of the drainpipe and insert it into the drain hole in the sink.
**9. Connect the garbage disposal (optional).**
If you are installing a garbage disposal, you will need to connect it to the sink. Follow the manufacturer’s instructions for connecting the garbage disposal.
**10. Connect the dishwasher hose (optional).**
If you are installing a dishwasher, you will need to connect the dishwasher hose to the sink. Follow the manufacturer’s instructions for connecting the dishwasher hose.
**11. Turn on the water supply.**
Once all of the plumbing connections have been made, you can turn on the water supply to the sink. Check for leaks around the sink and the plumbing connections. If there are any leaks, tighten the connections or apply more plumber’s putty.
