How to Install a Floating Vanity in 4 Steps


A floating vanity is a great way to add storage without taking up too much space in a small bathroom. This functional addition is stylish and offers an opportunity to customize the look and feel of your bath by choosing the height of the vanity cabinet.

When installing a floating vanity cabinet, we recommend consulting a professional if you are unfamiliar with installing bathroom fixtures.

Steps for Installing a Floating Vanity

Step 1. Mark the Vanity Placement

To get started with the process of installing a floating vanity, first outline the location on the wall where your vanity will sit.

Be sure to subtract the thickness of the countertop from the finished height of the vanity and draw a level line at that dimension from the floor.

Step 2. Locate and Mark Wall Studs

Locate and mark the location of the wall studs to which you will fasten your vanity. You can find studs by listening for a solid sound as you knock on the wall or by using a stud finder.

Mark where you locate the studs using a pencil. As you make your marks, make sure you’ve accounted for the height of the vanity from the floor.

Note: If the studs in your bathroom do not line up to the mounting location for your vanity, wood blocking can be installed between the studs using standard 2 x 4s.

Step 3. Mount and Level the Vanity

Make sure you have another person available to help you mount and secure the floating vanity. Use a few buckets and pieces of wood to raise the vanity to the right spot on the wall, where you previously made pencil markings.

Thread the mounting brackets supplied with your vanity. Drill pilot holes and mount the vanity into place by drilling deck screws into the wall studs. Double-check that everything is lined up and level for a clean and stylish finish. Place a few items inside the vanity to ensure it is secure and holds up well.

Note: Deck screws are the materials that will come with your floating vanity cabinet when purchased from Signature Hardware.

Step 4. Attach Doors, Drawers, and Hardware

Once the vanity is securely attached to the wall, finish the installation by attaching any drawers or doors, if not already attached. Use a screwdriver to adjust the position of the vanity doors as needed. Insert any drawers and install handles or knobs to finish the look.

Finish the Look

Once your floating vanity is secured to the wall, finish the project by installing the sink or new vanity top. Work with a plumber if you do not have general knowledge of plumbing to avoid any water issues in your bathroom.

Common Questions About Floating Vanity Installation

How much weight can a floating vanity hold?

The weight a floating vanity can hold depends on a few different factors:

  • Vanity size

  • Mounting hardware and technique

  • Quality of installation

  • Vanity construction

To ensure your vanity can handle the weight of your daily essentials do some research on the vanity itself, consider the weight of your essentials, and utilize toggle bolts or drywall anchors built to handle a specific weight capacity.

How far off the floor should a floating vanity be?

While floating vanities can be installed at any height, the typical distance is about 28” to 36” from the floor to the top of the countertop.

Are floating vanities a good idea?

A wall-mounted vanity opens the flow of a small bathroom, creating a minimalist feel. It’s the perfect choice to complete your home's modern or contemporary look.

The extra floor space below a wall-hung vanity can make the bathroom appear larger and because you can easily customize the height, you can create more room underneath to tuck baskets, a bathroom scale, or a child’s step stool underneath. This lends an airy feel to nearly any bathroom, but the benefits go beyond aesthetics.
