How To Remove Your Glued Sink And Install A New One
Prepare The Kitchen Space
The first thing you want to do is clear off the countertop and empty out all the cabinets beneath the sink. You’ll also want to remove any items hanging on the walls or stored on shelves near the sink. Once the area is cleared, lay down a drop cloth or old towels to protect your floors from water damage.
Next, locate your shut-off valves for both hot and cold water and turn them clockwise to shut off the flow of water to your sink. If you don’t have shut-off valves, then you should shut off the main water supply line to your home. Once the water is turned off, open up your faucets to release any remaining water in the lines and allow them to drain.
Now would also be a good time to clear out any garbage disposals or dishwashers that are connected to your sink. You can do this by disconnecting the power supply and water lines. If you have a garbage disposal, there will likely be a ring located beneath it that you can unscrew with a wrench. For dishwashers, there should be screws along the side of the unit that you can remove.
With the area now prepped, you can move on to Step Two.
Remove Garbage Disposal And Dishwashers
Dishwashers are usually connected with a Phillips head screw. The garbage disposal might be held in place by one or two bolts. If your model has an electrical connection, be sure to unplug it as well. You will also need to disconnect the drainpipes from the sink before removing it.
Once all of these connections are severed, you should be able to lift the sink out of its hole. If it is still stuck, you can try gently prying it up with a putty knife or flathead screwdriver. Be careful not to damage the countertop as you do this. If the sink is still not coming loose, you may need to use a hairdryer or heat gun to loosen the adhesive. Be very careful when using this method, as too much heat can damage the countertop.
With the sink finally removed, you will be able to access the underside of the countertop and see how it is attached. In most cases, it will be held in place with screws or nails. Remove these fasteners and lift the countertop off of the base cabinets. You may need help from another person to do this, as countertops can be quite heavy. With the countertop removed, you should now have full access to the sink area and be able to proceed with your repair or replacement project.
Disconnect The Drain Line
This can be done by using a pair of pliers to loosen the fitting that secures the drain line to the sink. Remove all of the remaining water from the line using a plunger after placing it in position.
Then remove the P-trap. This is located under the sink and is what connects the drain line to the sewer line. Once these are loosened, you should be able to remove the P-trap without any issues.
The last thing you will need to do is disconnect the supply lines. These are the lines that connect the water supply to the sink. To do this, you will need to use a wrench to loosen the fittings that secure them in place. Once these are loosened, you should be able to remove the supply lines without any issues.
Drain The Excess Water
The next step is to eliminate the extra water from your sink. To do this, you should remove the plug that is located at the bottom of your sink. Once you have done this, you will need to place a bucket underneath the sink in order to catch any water that may drip out.
Then you should turn on the faucet and allow the water to drain out completely. Once the water has finished draining, you can then proceed to the next step.
Detach The Drain Pipe
The next thing you need to do is detach the drain pipe. To do this, simply unscrew the nut that is holding it in place. You may need to use a wrench or pliers to get it loose. Once you have removed the nut, you can pull the drain pipe away from the sink.
Now that you have removed the drain pipe, you should be able to see the P-trap.
With the P-trap removed, you should now be able to see the sink strainer. The sink strainer is a metal screen that covers the drain opening and prevents debris from going down the drain. To remove the sink strainer, simply unscrew it from the drainpipe.
Now that you have removed the sink strainer, you should be able to see the stopper. The stopper is a plug that fits into the drain opening and prevents water from going down the drain. To remove the stopper, simply pull it out of the drain opening.
With the stopper removed, you should now be able to see inside the drain opening. If there is any debris or buildup inside, use a plunger or plumbers snake to clear it out. Once you have cleared the drain opening, you are ready to move on to the next step.
Disconnect The Faucet
Remove the faucet by unscrewing it from the top of the sink. Use a wrench to loosen any nuts or bolts that are holding it in place. You may need to use a pair of pliers to remove the washers and O-rings.
Once the faucet is removed, use a putty knife to scrape off any old plumber’s putty that is sealing the hole where the faucet was mounted. Be sure to clean off any residue so that you have a clean surface to work with when you install the new faucet.
If you have a sprayer hose attached to your sink, disconnect it at this time as well. There should be a coupling nut that you can unscrew with your hands.
With the faucet and sprayer hose removed, you should now have access to the sink’s drain pipes. There are two main types of drains – those with a stopper and those without. If your sink has a stopper, you will need to remove it before you can proceed.
To remove a drain stopper, simply pull it up and out of the drain opening. You may need to twist it back and forth a bit to loosen it from the sealant that is holding it in place. Once it is loose, you can lift it out and set it aside.
If your sink does not have a stopper, you will need to remove the drain cover. This is usually a simple matter of unscrewing a few screws. Once the cover is off, you should be able to see the top of the drain assembly.
There may be a lever on top of the drain assembly that you need to flip in order to release the drain. Alternatively, there may be a screw that you need to remove. Consult your sink’s manual for specific instructions on how to do this.
With the drain released, you should now be able to lift out the entire assembly and set it aside. Be careful not to lose any small parts like washers or O-rings. These will need to be replaced when you reassemble the sink later.
Loosen The Sink Clips
Use a putty knife or screwdriver to loosen the sink clips that are holding the sink in place. You may need to use a little force to get them started, but be careful not to damage the sink. Once the clips are loosened, you should be able to pull the sink away from the countertop.
If your kitchen sink is glued down, you’ll need to take a few extra steps to remove it. This comprehensive guide will show you how to remove a kitchen sink that is glued down, step by step.
Removing Liquid Nails
The next step is to remove the liquid nails that are holding your sink in place. You can do this with a putty knife or a chisel. Just insert the tool under the lip of the sink and pry it up. Work your way around the entire perimeter of the sink until it is loose.
Once you have removed all of the liquid nails, you should be able to lift the sink off of the countertop. If it is still stuck, you can try using a heat gun to loosen the adhesive. Be careful not to overheat the plastic or damage your countertop.
Removing The Sink
The next step is to remove the sink. You will need to use a utility knife to cut through the sealant around the edge of the sink. Be very careful not to damage the countertop as you do this.

You may need to use a putty knife or other tool to remove any remaining caulk or glue from the edges of the sink. Be sure to clean up any messes inside the cabinet as well. Once everything is clean, you can reinstall your kitchen sink according to the manufacturer’s instructions. 
How To Fit A New Kitchen Sink
The most difficult task in installing a new kitchen sink is usually removing the old one, particularly if it is glued down.
Fitting a new sink is not as difficult as you might think, but there are a few things that you need to know before you start.
Firstly you need to do is to turn off the water supply to your kitchen. This is usually done at the mains stopcock. When the water has been shut off, you can begin to remove the old sink.
If your sink is glued down, then you should use a putty knife or similar tool to loosen the glue. Start at one end of the sink and work your way around until the entire sink is free. Once the sink is free, you can lift it out and dispose of it properly.
Now that the old sink is removed, you can start to fit the new one. The first thing that you need to do is to place the new sink in position and mark out where it needs to be cut. Most sinks come with a template that you can use to mark the correct position.
Once you have marked the position of the sink, you can start to cut it out. Make sure that you follow the manufacturer’s instructions.
If your new sink comes with a sealant, then you need to apply this around the edges of the sink before you fit it in place. This will help to create a watertight seal and prevent any leaks. Once the sealant is in place, you can fit the clips and secure your sink in place. 
Turn on the water supply and check for any leaks. If there are any leaks, then you will need to apply more sealant. Once the sink is secure and there are no leaks, you can start to use it.
