How to Remove Your Old Bathroom Vanity
Step 1 – Turn Off the Water Supply
Close the fixture shutoff valves. These can normally be found under the sink inside the vanity. If your vanity has no shutoff valves or if they’re malfunctioning, turn the water off at your home’s main water supply. Once that’s done, you need to open the tap to release any pressure and drain the water.
Step 2 – Disconnect the Water Supply Lines
Place a bucket under the water supply tubes so it catches the water left in the lines. Use your spanner to loosen the compression nut and slip the supply tube off of the valve. Take this chance to inspect your shutoff valve and make sure it’s not leaking. If it is, you may need to replace it.
Step 3 – Remove the Drain Trap
Place your bucket under the P-trap to catch any water. Loosen the two outermost slip nuts with multigrip pliers or with your hands if the P-trap is plastic. Remove the P-trap and dump the water inside into the bucket. Finally, seal the pipe leading into the wall with a rag to block off the sewer gas.
Step 4 – Remove the Mirror (Optional)
Unless you plan to replace the mirror, you can leave it in place. However, if it isn’t attached to the wall and instead rests on the countertop or backsplash, it’s best to remove it as it might break while you’re removing the cabinet.
Step 5 – Cut the Sealant
Before removing the old vanity, you must first cut the caulk along the edges where the countertop and cabinet meet the wall. Afterwards, gently tug the vanity countertop free from the wall.
Step 6 – Remove the Countertop
Vanity countertops are either held in place with brackets or glue. If it’s held with brackets, unscrew them. If it’s glued to the cabinet, you can use a hammer and chisel. Try to do so from the inside if you plan to reuse the sink or vanity.
You can then remove the countertop. Be careful not to damage the walls as you do, and move the countertop, sink, and tap out of the bathroom to free up space.
Step 7 – Remove the Cabinet
If your vanity cabinet has trim, you first need to remove those. They are usually fastened with screws. The cabinet might also be anchored to the floor with screws or nails.
Remove all screws with a drill or screwdriver, and remove nails with a flat pry bar. When prying nails, lever the pry bar against a wood block to prevent damage to the wall and floor. Finally, pull the cabinet away from the wall. Be careful not to damage the valves as you do so.
Step 8 – Cleanup
Remove any remaining sealant with a putty knife or scraper. Patch and paint the wall and floor if needed (for example, if your new vanity is smaller and wouldn’t cover damaged paint). You’re now ready to install your new vanity. Make sure any waterproofing has not been damaged or penetrated. Failure to do so may cause water seepage in to your wall causing structural damage. Consult a professional waterproofer if you have any concerns.
How to Install Your New Bathroom Vanity
Step 1 – Set the Vanity
Locate the wall studs within the area you plan to install your vanity. Use a stud finder and mark their centers. Measure the height of the vanity cabinet and mark this height on the back wall and sidewall, if applicable. Ensure your line is straight with a level.
Set the cabinet into position and make sure it’s level with the line you drew. You can also slip shims under the cabinet to level it. With the cabinet in place, drive cabinet screws through the mounting strip and into the wall studs of the back wall. If there is a sidewall, fastening the cabinet to that wall comes later.
Step 2 – Sidewall Installation (if Applicable)
Fill any gaps between the sidewall and cabinet with a filler strip. Use a profile gauge or carpenter’s compass to draw the gap’s profile onto a wood strip and cut it out. Adjust the wood strip as necessary, sand and finish it, and attach it by driving screws through the inside edge of the cabinet. If the filler strip is thin, you glue it into place instead of using epoxy.
Fastening the cabinet to the sidewall is optional, but it’s best done to further secure the cabinet. Cut 2 blocks about 3 mm shorter than the gap between the cabinet and sidewall. Place these blocks in the gap and secure them by wedging in wood shims. These will support the cabinet while you’re driving screws in.
Finally, drive a plasterboard screw through the cabinet and into the wall stud.
Step 3 – Install the Vanity Top
Place construction adhesive onto the cabinet’s top corners and carefully place the countertop onto it. If the sink is separate, install that first. Your vanity may also come with a separate backsplash. Once you’ve installed the countertop, apply construction adhesive to the back of the backsplash in a wave pattern and press it against the wall.
Step 4 – Connect the Water Supply Lines
Simply follow the manufacturer’s instructions for installing the tap and drain fittings and connecting the sink drain to the drain trap and branch drain.
Step 5 – Caulk the Edges
Apply caulk where the countertop and the backsplash, if applicable, meet the wall. Let it cure for 24 hours.
Step 6 – Cleanup
You’re done! Just clean your bathroom up, and you’re ready to enjoy your new bathroom vanity.
