How to install a floating vanity

Important: you’ll need 1 or 2 persons for help, depending on the size and weight of the vanity. Remember: safety first, don’t try to lift something if it’s too heavy.

For this article, let’s assume you don’t do any renovation, the wall area, tiling and the essential plumbing is ready to use (there is hot and cold water access and also pipe for the drain water).

Tools and preparations

The floating vanity is, most of the time, a simple cabinet with a strong back panel that can be directly mounted to the wall. The following list will serve as a guide to perform the mounting without any problem:

  • The back panel should have pre-drilled mounting holes or hanging hardware, or if not, you should drill the holes for yourself, or mount hanging hardware onto it.

  • Use at least four points to attach the vanity to the wall - or even more, depending on the size and weight of the vanity.

  • Use strong screws that go into the wall minimum 3” deep.

  • Always use wall plugs according to your wall type (brick, concrete, drywall, etc.)

  • Use the right drill bit according to your wall type - if there is tiling on the wall, you will need to use special ceramics or glass drill bit to go across the hard surface.

Is it possible to install a floating vanity on drywall?

In the US, there are many houses with drywalls. However, that should not hold you back from having a floating vanity. It is recommended to mount it directly to the studs, this way it will provide a better support for the weight of the vanity. Not sure where the studs are? You can use a stud finder detector.

If the studs are not conveniently positioned or you cannot identify their location, you can still use drywall anchors for a stable mounting.

The steps for installing the floating vanity

In this guide, we show you how to install a mybettershelf floating bathroom vanity. The guide may work for most other wall-mounted vanities as well.

  1. Remove the drawer from the cabinet. This way, you can reduce the weight of the cabinet for easier mounting, and also you can access the mounting points on the back panel.

  2. Check the mounting points on the back of the cabinet. Measure your wall and mark these points on the wall surface.

  3. Drill the holes. Make sure there is no water pipe and electrics in the wall where you drill the holes. When you have the holes, insert the wall plugs.

  4. Have the cabinet held to the wall so you can drive in the screws. Start with the upper screws - when those are ready, those may be able to hold the cabinet and you can continue with the rest of the screws.

  5. Make sure all the screws are secure and fastened.

  6. Put the sink on top of the vanity. Optionally you can glue it onto the surface.

  7. Install the plumbing (hot and cold water access) and connect the sink with the drain tube.

  8. Put the drawers back and make sure it is well positioned on the soft-close slides. The U-shape drawer gives space for the tubes internally.

Frequently asked questions

How hard is it to install a floating vanity?

A floating vanity installation is a manageable DIY project if you have basic drilling skills and the right tools. The most important steps are marking the mounting points accurately, using the correct wall plugs for your wall type, and having a second person to help lift and hold the cabinet in place during mounting. The plumbing connection is the only step that may require a professional if you are not comfortable working with water pipes.

Can I install a floating vanity on drywall?

Yes — installing a floating vanity on drywall is possible. The best approach is to mount it directly into the wall studs, which provide the strongest support. If the studs are not conveniently positioned, high-quality drywall anchors rated for the weight of your vanity are a reliable alternative. Use a stud finder to locate the studs before drilling.

Can I install a floating vanity on a tile wall?

Yes — but it requires a special ceramic or glass drill bit to go through the tile surface without cracking it. Drill slowly and at low speed, ideally with a piece of tape over the drilling point to prevent the bit from slipping. Once through the tile, switch to a regular masonry or concrete bit for the wall behind. The rest of the installation process is the same as on any other wall type.

Do I need a plumber to install a floating vanity?

Not necessarily — if you are comfortable with basic plumbing, connecting the hot and cold water supply and the drain tube is straightforward. If you are not experienced with plumbing work, it is recommended to have a professional handle the water connections, while you manage the cabinet mounting yourself.

How high should a floating vanity be mounted?

The standard height for a floating vanity is 80–85 cm (31–33 inches) from the floor to the top surface of the vanity, not including the sink. This is the most ergonomically comfortable height for most adults. One of the key advantages of a wall-mounted vanity is that this height can be adjusted to suit your exact needs — taller users may prefer 85–90 cm, while a lower height works better in children's bathrooms.

What tools do I need to install a floating vanity?

The essential tools are: a drill with masonry and (if needed) ceramic drill bits, a screwdriver, a spirit level, a pencil for marking, and a stud finder if you have drywall. Wall plugs appropriate for your wall type and strong screws (minimum 3 inches / 7.5 cm long) are also required.
