I.Tools and materials needed before installation
Before you begin, please prepare the following tools and materials:
- Core Equipment: New bathroom vanity (with or without countertop), faucet and drain pipe
- Tools: Screwdriver, electric drill, adjustable wrench, pliers, utility knife, hole saw
- Measurement and Positioning: Level, measuring tape, pencil, wall detector
- Installation Supplies: Grout and grout gun, washers, cabinet screws and expansion bolts, plumbing tape and putty
- Safety Equipment and Cleaning Tools: Gloves, safety goggles, mask, bucket and rags
II: Installation steps
1：Turn off the water supply and remove the old cabinet.
①：First, turn off the water supply. Locate the angle valve under the sink and turn it clockwise to close it. Then turn on the faucet to release any remaining water pressure in the pipes.
②：Place a bucket under the sink and use pliers to loosen the nut on the P-trap, disconnecting it from the drain pipe. Then use an adjustable wrench to remove the hot and cold water supply pipes.
③：Next, remove the old cabinet: Use a utility knife to cut the grout where the backsplash meets the wall. Unscrew the screws securing the cabinet.
Carefully pull the cabinet out from the wall. If the countertop is integrated with the cabinet, you may need to remove the countertop first.
④：After removing the old cabinet, check the walls and floor for damage. If necessary, repair any holes or cracks before proceeding to the next step.
2: Plan the space and mark the locations on the wall.
① Measure the installation area to ensure the width, depth, and height of the new bathroom vanity fit the space. If you choose a small bathroom vanity with a sink, even more precise measurements are needed to ensure sufficient room for movement.

Standard countertop height is typically 80cm - 85cm. For wall-mounted vanities, it's recommended to adjust the height according to the height of family members.
② Use a wall detector to locate the wall columns within the installation area and clearly mark them with a pencil. This is a crucial location for fixing the cabinet later. Temporarily place the new cabinet in the designated position, check the dimensions and alignment, and lightly draw the cabinet's outline on the wall as a reference.
③If there are no pre-drilled pipe holes on the back of the cabinet, measure the distance from the ground to the hot and cold water pipes and the drain pipe, mark these dimensions on the back of the cabinet, and then use a hole saw to make the holes.
3：Place and Level the Cabinet
① Place the cabinet in the designated position, aligning it with the markings on the wall. Use a level to check that the cabinet is level front to back and side to side.
② If it is not level, insert shims under the cabinet to adjust it until it is perfectly level. This step is crucial, as it affects the subsequent countertop installation and cabinet door alignment.
4. Secure the cabinet to the wall (vanity installation)
After leveling the cabinet, secure it to the wall post. Drill holes in the back panel of the cabinet corresponding to the wall post positions, then screw in the holes to secure it.
If there is a mounting strip on the back of the cabinet, use that position for securing. Avoid using only expansion bolts to fix it to the drywall; only by securing it to the wall post can you ensure stability and prevent it from tipping over.
5: Install faucets and sinks
It will be easier to install the faucet and drain assembly before installing the countertop.
Please follow the instructions:
- Insert the faucet into the hole in the sink or countertop.
- Secure it from below using washers and nuts.
- Apply plumber's putty to the edge of the drain outlet and press the drain assembly in.
- Tighten the retaining nut from below, wiping away any excess putty.
If you are installing a double sink bathroom vanity, please repeat these steps to install two faucets and ensure that the hot and cold water pipes are laid out properly.
If the sink and countertop are separate units, please install the sink on the countertop first, and then place the whole unit on the cabinet.
6: Install the countertop
Apply a thin, even layer of silicone adhesive to the top edge of the cabinet. Carefully place the countertop in place, ensuring it is centered and level.
Press the countertop firmly and wipe away any excess adhesive with a damp cloth.
If the countertop has a backsplash, apply silicone to the back and press it firmly against the wall, also applying silicone sealant to the seam between the backsplash and the countertop.
7: Connect the water pipe
Reconnect the water supply and drain pipes: Wrap plumber's tape around the threaded joints to ensure a seal.
Connect the water supply pipe to the faucet, tightening it by hand first, then gently securing it with a wrench.
Install the P-trap and connect it to the drain pipe inside the wall.
Turn on the water supply and check all connections for leaks. Let the water run for a few minutes and observe carefully.
8: Install doors, drawers, and hardware.
Install cabinet doors and drawers according to the instructions, and finally install handles or knobs. If necessary, adjust the door hinges to ensure smooth opening and closing.
III: Part Three: Final Finishing and Cleaning
Apply a ring of grout to the seams between the cabinets and the walls and floor, then smooth it out with your fingers or a tool to create a neat and aesthetically pleasing finish.
Wipe down the countertops, sink, and cabinet surfaces, and admire your newly created bathroom space!
