How To Remove A Kitchen Sink That Is Glued Down

Have you ever tried to remove a kitchen sink, only to find that it is glued down? It is a typical problem among homeowners, especially when moving into a new apartment with an already installed sink.

At first, it may seem impossible to remove the sink. However, by following the right steps, you’ll be able to complete the mission successfully.

The step-by-step guide below will show you how to remove a kitchen sink that is glued down and install a new one. 

The Tools You’ll Need to Remove a Kitchen Sink

With the few tools, removing a glued sink and replacing it with a new one is a quick and simple process.

 Here are some appropriate tools you’ll need for the removal process:

  • Adjustable wrenches
  • Screwdriver
  • Hammer
  • Small bucket
  • A putty knife
  • Pipe wrench
  • Old towel
  • Work gloves
  • Heat gun or hair dryer

It is a good idea to take a picture of the plumbing setup underneath the sink before removing the unit for you or your plumber in case something goes wrong. It is better to be prepared than calling for an emergency plumber to fix the damage.

How to Remove Your Glued Sink and Install a New One

By carefully following the steps below, you’ll remove the sink easily and efficiently.

Step 1: Prepare the Kitchen Space

Preparing the kitchen space is essential for the removal process. To properly prepare the area, turn off electricity, the water, and the gas (if applicable). You want to make sure your kitchen is safe to work in.

You will also need to remove heavy appliances and kitchenware that may get in the way. Don’t forget to remove all fittings and plumbing fixtures and put them elsewhere so you can use them later. Disconnect all knobs, tapware, and lighting fixtures from your kitchen.

You can also throw a cloth over the floor to avoid damaging or scratching it.

Step 2: Remove Garbage Disposal and Dishwashers

Once you are done cleaning and preparing the kitchen space, it is time to remove your garbage disposal and dishwasher. All you need to do is unplug the dishwasher and move it to the other side of the kitchen. The same goes for your garbage disposal.

If necessary, check the manufacturer’s manual when disconnecting garbage disposal and dishwashers to avoid any damage. The point of this re-organization is to make more space available around the sink so you can remove it carefully, without damaging anything on the sides.

Step 3: Disconnect the Drain Line

The next step is to disconnect the drain pipes. Use an adjustable wrench to turn off the drain pipe and supply lines.

Step 4: Drain the Excess Water

If there is water left in the pipes, drain them until there is nothing inside. Place a bucket under the sink to let the remaining water run. Once the drains are empty, remove the bucket.

Step 5: Detach the Drain Pipe

If you haven’t done this already, now is the perfect time. Make sure to detach the p-trap pipes below the sink. Remove any sink parts that may get in your way.

Step 6: Disconnect the Faucet

While the previous steps are essential for removing a sink that is glued down, this one is optional. Disconnecting the faucet is a recommendable step for removing undermount sinks from granite epoxy.

All you need to do is turn off the main valves and open the faucet to relieve pressure. Next, loosen the nuts and remove the tubes.

Step 7: Loosen the Sink Clips

Find the clips holding the sink, then loosen the screws using your screwdriver. Depending on the glue, the sink will also release and make the process easier when you remove it.

Take the utility knife and put it between the sink and the granite counter. If the sink is attached with liquid nails, you will have to use additional force when removing the old sink.

Step 8: Removing Liquid Nails

While removing dried liquid nails from a sink may seem impossible at first, there is one old trick you could try.

First, you will need to soften the construction adhesive or liquid nails. To do this, you will need a blow dryer. Once the glue starts melting, scrape it off using a putty knife. Wipe the surface to remove any remaining waste.

Step 9: Removing the Sink

Now that you’ve removed the liquid nails and the sink clips, it is about time to remove the sink.

First, remove the undermount sink epoxy if you have a glued undermount sink or any other type of sink you have. Next, remove the support from underneath the sink and lower the sink carefully.

Step 10: Clean Up

After successfully removing the glued sink, it is essential to clean the remaining glue and old adhesive off the countertop material, especially if you plan on adding a new one.

Clean up the waste and remove the unnecessary items to prepare your kitchen for sink installation.

How to Fit a New Kitchen Sink

Now that you know how to remove a glued down sink, you probably want to know how to fit a new one.

  • Attach the clips
  • Fit the taps and strainer
  • Add a sealant to the underside
  • Lower the sink into the cutout
  • Tighten the clips
  • Connect the water supply
  • Add sealant

To successfully fit a new sink, you will need:

  • Plumber’s putty
  • Silicone sealant
  • Screwdriver
  • Rubber hammer
  • Adjustable wrench

Attach the clips to the sink’s underside and fold them in the direction of the sink bowl. Take the old sink taps and slot them in the right holes, carefully following the manufacturer’s manual.

Take the drain strainer and add a ring of plumber’s putty around the sink’s underside. Secure it tightly. Lean the sink on the side and apply the rubber caps to the drain strainers’ bottom.

Carefully run silicon sealant around the sink’s entire edge. Add the sink into the countertop, ensuring it is the right fit.

Tighten the clips using a flathead screwdriver, locking your new sink into place.

Use the adjustable wrench to connect the water supply and turn on the lines. If you are sure everything is in place, run an additional sealant layer.
