Before you start installing a new vanity, find one that suits your style and needs. There are essentially two options to choose from: free-standing vanities for small spaces and built-in vanities that can either be attached to a corner or on a wall mount to provide more counter space.

And you should also consider whether you want a vanity alone or one with a sink. Do you want a vanity with a single or double sink?

Clean and prepare the installation area, and then follow these steps to ensure a robust installation. Bathroom vanity tops often come with the manufacturer’s instructions on how to install the vanity correctly.

Mark the height of the vanity in three different places as well as the width. Be sure to choose the right height for comfortable use.

The next step is to locate the stitches on the wall using a stud finder so you can mark them within the outlined area you just completed above.

Most bathroom amenities are open backs that allow for easy installation. If yours has a closed-back, cut holes for plumbing. First, measure the distance from your contour on the wall to the plumbing pipes. Transfer the measurements you made to the vanity of the new bathroom and carefully cut the holes using a hole saw.

To make your installation easier, you can remove the vanity doors and drawers. Be sure to refer to the included instructions on how to remove and install them on the bathroom vanity.

Set the vanity in the bathroom while ensuring that it is well decorated with the marks you have made on the wall. Make sure the vanity is smooth from side to side and front to back. Use the adjustable feet on the bottom to make small adjustments. Alternatively, you can use shims to make the adjustments by pushing them under the base and cutting to fit an auxiliary knife.

Drill a pilot hole through the affordable bathroom vanity back into the wall pin. If you have tile walls, first use a piece of tile and then use a piece of wood for the stud. If you have holes that are not in line with your posts, be sure to use wall anchors. Then secure your vanity with the supplied screws. Now you have learned how to install a bathroom vanity.


If you are also installing a sink, it is time to add it to the vanity and connect the plumbing lines.

Install the faucet and drain on the sink before installing it on the bathroom vanity.

Add a thin bead of silicone adhesive to the edge opening of the sink in the vanity and be careful not to apply it to the vanity.

Get an extra hand to carefully set the sink to the bathroom vanity so you can make sure the plumbing system is well lined. Allow the adhesive to cure.

Then you can now reconnect the drain. Get a plumbing kit if your tailpipe is too short, or cut it if it is too long.

Reconnect your supply lines. It is a good idea to replace any old water supply valves and other fittings. The most important thing is to follow the correct steps when replacing valves on your brass or copper pipes.

Once you have installed the new valves, you can now turn on the water and let it run for a while to check for leaks. Then attach the supply lines to the new valves.

Apply the right type of bathroom bowl along the back edge of the sink, and clean up any excess.

Turn on the water on the sink faucet to check for leaks and make small adjustments if necessary.

Put on the bathroom vanity doors and drawers you removed to complete the process of how to install a bathroom vanity. And now your vanity with a utility sink is fully installed.
