Before You Begin to Remove a Bathroom Vanity


Rarely, a bathroom vanity may be fixed into the floor or put before other fixtures, making it difficult or impossible to remove the cabinet without damage. In certain situations, cutting the cabinet into portions to remove it can be necessary. This task is made easy with a reciprocating saw equipped with a demolition blade. When this is required, it is preferable to cut the vanity cabinet into parts after separating the sink and countertop from the vanity.


While working, keep an eye on the state of the supply lines, p-trap, shut-off valves, and other plumbing that services the sink and drain. Now, while the vanity is gone, could be a good opportunity to replace these pieces, as they can lose their effectiveness with time. In the meantime, you will need the following items (tools and materials) to get started on removing a bathroom vanity:




  • Bucket

  • Adjustable wrench

  • Channel-lock pliers

  • Rag

  • Screw gun

  • Utility knife

  • Flat pry bar

How To Remove Bathroom Vanity


Step 1 of How to Remove a Bathroom Vanity: Shut off the Water Supply


As the first step of "How to remove a bathroom vanity", it's preferable to take the vanity doors off of their hinges since the cabinet will be removed otherwise. This will allow you to have easier access to the plumbing and lighten the cabinet when you remove it from the bathroom. Cut off the water flow to the faucet's hot and cold taps. Closing the fixture shutdown valves, which link the hot and cold supply tubes to the branch line stub-outs under the sink, is often how to accomplish this. To close the valves, turn each one completely clockwise.


You will need to locate the shutoff valve for the main water supply in your house and turn off the water there if the shutoff valves on your vanity faucet are broken or malfunctioning. After turning off the water, completely open the faucet to allow the water to run out and relieve any pressure.

Step 2: Disconnect the Water Supply Tubes


Working on one tube at a time, disconnect the water supply tubes that connect the shutoff valves to the faucet. In order to collect water from the line, place a bucket beneath the shutoff valve. Using an adjustable wrench, loosen the compression nut (or hose connector) on the supply tube and turn it counterclockwise to remove the threaded nipple. Remove the supply tube by sliding it off the valve. There will be a tiny copper compression ring or sleeve on the tube behind the compression nut when there is a compression connection, which is typical with copper or brass supply tubes.

Check for leaks by attentively inspecting the shutoff valve. You will need to repair the fixture cutoff valve and turn off the water supply to the house at the main shutoff valve if water leaks through the valve even after it has been turned off.


Replacing the sink and faucet might also be an excellent opportunity to replace the flexible supply tubing and fixture shutoff valves. When installing a new vanity and sink, it's usually better to avoid reusing old parts because they have a limited lifespan and could need to be replaced soon anyhow.


You may wonder, "How to remove vanity with water lines in bottom?" In this case, you should examine the bottom of the vanity. Take a look at the size of the holes cut in the vanity to accommodate the waste pipe and the water supply lines. If the holes are large enough to accommodate the pipes and the valves, no action is needed. If the holes are too small to accommodate the valves, use the basin wrench to detach the valves. Place a plumbing cap over each of the supply lines to keep debris out of the pipes as you work.

Step 3 of How to Remove a Bathroom Vanity: Remove the Drain Trap


To collect any standing water that may leak out when the trap is disconnected, place a bucket beneath the P-trap assembly beneath the sink. The trap assembly consists of three parts: an elbow-shaped straight trap arm that connects to the branch drain pipe in the wall; a U-shaped trap bend; and a straight tailpiece portion that is attached to the drain pipe that extends down from the sink.

Loosen the two outermost slip nuts, one at the wall end of the trap arm and one on the sink tailpiece, to remove the P-trap. You might be able to manually loosen the bolts on plastic pipes. If not, use channel-lock pliers. To loosen the nuts, rotate them counterclockwise. Remove the trap assembly with caution after sliding the nuts away from the threaded ends of the pipes. Fill the bucket with the water that is in the P-trap. To fully seal off the exposed pipe going into the wall, insert a rag inside of it. This stops the room from being filled with sewer gas.

Step 4: Remove the Wall Mirror


If you'd like, take the vanity mirror off. Since it's easy to shatter the mirror when removing the cabinet, this is an excellent option when the mirror is resting on the backsplash or vanity countertop. If the mirror is affixed to the wall with adhesive, it is advisable to keep it there unless you want to replace it.

Step 5 of How to Remove a Bathroom Vanity: Cut the Caulk Joints

Step 6: Remove the Vanity Top


Here you will see how to remove the bathroom vanity top without damage. Take out the vanity countertop; you can normally leave the faucet in place and remove it later if you'd like. If the countertop unit is attached to the vanity cabinet by clips or brackets, check underneath the vanity top. If so, take these brackets off by unscrewing them. Raise the countertop's front edge. Here we will see how to remove a vanity top that is glued down. A vanity might be glued to the cabinet edges if it doesn't come off of the cabinet. The countertop can be pried up, or you can choose to leave it in place and remove the complete cabinet (next step).


Take care not to scratch the wall surfaces when you pull the countertop up from the cabinet and away from the wall. To make room for the vanity cabinet to move about, it's essential to remove the countertop, sink, and faucet completely from the bathroom.


It's crucial to remember that even if you cut off the water to the entire house, you're not done until you've covered the exposed pipes. These are active pipes that are linked to the rest of your home's plumbing system. The house would practically flood if you switched on the water again without the caps. Any hardware store in your area carries pipe caps. To see how to remove a bathroom vanity top and backsplash, follow these steps:

Step 7 of How to Remove a Bathroom Vanity: Remove the Vanity Cabinet


If any trim is present where the cabinet meets the walls, remove it. To find out how and where a cabinet is attached to the wall, look inside; most are secured with a few screws that are inserted into wall studs and through a mounting strip. Additionally, it's conceivable that the cabinet will be fastened to the floor using screws or nails inserted through the nailing blocks located at the bottom. Using a drill or screwdriver, remove every screw.


If the cabinet is nailed to the wall, use a flat pry bar to gently pry it off. Position a wooden block in between the pry bar and the wall, then press the lever against it. To avoid breaking the wall, this is crucial. Take the cabinet out from behind the wall. Take care when moving the cabinet so as not to damage (or switch on) any plumbing valves that fit through holes in the rear panel.

Step 8: Complete the Project


Using a putty knife or scraper, remove any leftover caulk from the wall and clean it up. Before putting in the new vanity, make plans to patch and paint the wall and/or floor if necessary if the new cabinet is shorter or smaller than the previous one.


Please note that you can remove the vanity and call this step of the project finished if you are able to turn off the water at the vanity. Congratulations! If your new vanity will be built in the same location and you don't want to bother with removing the valves: You don't need to add any unnecessary complexity to your life.


You can demo your vanity instead of dismantling the plumbing system. Cut into the vanity right next to the plumbing with a multi-tool until the cabinet is readily removed. Conversely, if your plumbing was close to the vanity and you intend to relocate your plumbing or replace your valves. You can remove the shutdown valves and water supply tubes after removing your vanity top. To remove the vanity, we also had to see off the curved portion of the white pipe.
