Installing a bathroom vanity can be a daunting task, but it is often one of the best investments you can make. This article will walk you through installing your vanity between two walls and against the baseboard. 

Follow the 6 Steps to know How to Install Bathroom Vanity Against Baseboard 

You Will Need:

  1. Stud finder,
  2. Drill with 5/8″ masonry bit,
  3. Hammer or Mallet (if necessary),,
  4. Tape measure or straight edge measuring at least 12″,
  5. Pencil and ruler
  6. Level Instrument (water level)
  7. Screw and Screwdriver
  8. Adhesive/Glue

Step 1: Prepare The Space

Be sure that you have enough room to work. That means that you should keep the vanity at least one foot away from all walls and cabinets or whatever else may be in the way. How far away you need to go depends on how much space is required to swing a hammer. Most hardware stores sell special hangers for this kind of installation.

Step 2: Install The Vanity 

You’ll need to hold the vanity in place while you start this step, so you might want to use hangers or clamps for this job. Mark holes along the wall where studs are located using a stud finder. Drill 5/8-inch holes into the marked locations and insert anchors if necessary.

Step 3: Level It Up

Use a level to make sure your vanity is even and secure it in place with lag screws. How you go about doing this depends on the type of anchors, hangers, or clamps that you’re using.

Step 4: Fasten the Vanity’s Bottom to Studs

How you do this is different depending on which fasteners are being used. Follow the directions that come with your fasteners, but the goal is to attach the bottom of the vanity to wall studs through pilot holes or pre-drilled slots into this wood piece.

Step 5: Fill Gaps Between Vanity and Floor

If there’s a gap below your bathroom vanity, you’ll need to fill it with something. The best material for this kind of job is wood filler. If gaps are more than 1/8-inch wide, you might need to install blocking or a strip of thick wood instead.

Once the cabinet is installed correctly, caulk the gap between the wall and your bathroom cabinet with high-quality matching caulking. How long this takes depends on how large of a gap there is. If you have enough space, it might be easier to replace part of the wall first before doing this step. Spread caulking over an area slightly larger than your gap and smooth it down using a putty knife as soon as possible after applying to avoid wrinkles or lumps.

Step 6: Caulk Around Sinks, Tubs and Other Fixtures Last

It’s best to wait a few days before caulking around bathroom sinks, tubs, and other fixtures so that the caulk has enough time to set. It will help avoid future problems with mold or mildew. Use a damp cloth to clean up any caulk that gets on tile, porcelain, or other surfaces.

Once everything is caulked and dried, give the vanity a final once-over with a soft cloth to remove any dust or debris. You’re now ready to start using your new bathroom vanity!

Optional: Cut Out Baseboard For Vanity

You can cut the baseboard when you don’t want space between the wall and the vanity. Getting it done is not difficult.

To begin with, you’ll need to measure the vanity. Mark that size on the baseboard. After that, cut the baseboard.

There are usually two types of baseboard, wooden and Cement Plaster baseboard. If it is wood, you can cut it with Reciprocating Saw or Normal Chiseling / Hand Cutting.

If it is a cement plaster baseboard, the vibrating blade of the oscillating tool should break it. It will never be perfect, so the baseboard must be removed, plastered and painted after it breaks.

Should A Bathroom Vanity Be Against A Wall?

The bathroom vanity should be against a wall to give it stability. It may wobble or even fall over if it is not against a wall. This is also convenient for plumbing purposes, as the wall will hide any water lines or drainage pipes.

Where to Put a Bathroom Vanity?

The bathroom vanity should be placed against a wall. It can be placed next to the toilet or in another bathroom area, but it should be against a wall.

It ultimately depends on the layout of your bathroom and the size of your vanity. If you have a small bathroom, it may make more sense to put the vanity against a wall to save space. However, if you have a larger bathroom, you may consider putting the vanity in the middle of the room for a more open feel.

How Do You Fill the Gap Between Floor and Vanity?

To fill the gap between the bathroom vanity and the floor, use small pieces of molding; they can be painted to match the color of the vanity. If the vanity is against a wall, there is no need to fill the gap; it may look better if there is a small gap between the vanity and the wall.


You can fill the gap with silicone caulk if the gap is relatively narrow. If the gap is wider, you should include a backer rod to help support the caulk.

Is It Expensive to Replace a Bathroom Vanity?

It is not expensive to replace a bathroom vanity, but the cost may depend on the purchased type of vanity. A basic vanity can be found for around $100, while more elaborate and luxurious vanities can cost more. However, in general, replacing a bathroom vanity is not an inexpensive project.

How Long Do Bathroom Vanities Last?

Bathroom vanities can last for many (15-20) years if they are correctly taken care of. However, the finish may start to wear off over time or the vanity may become damaged. In these cases, it is necessary to replace the vanity.
