How to Install a Floor Outlet in Concrete

Last Updated on December 6, 2022

Concrete is stiff and unforgiving, making it arduous to make the needed hole for a power outlet. If you make a mistake, you could end up with an electric shock, or worse. And even if you get it right, the outlet might not work properly.

An Electrical outlet box is a convenient option for areas where you don’t want to have a bunch of cords trailing along the wall. There is a metal plate to protect the wiring and outlet, plus a cover to prevent dust from getting into the outlet when it is not in use.

You might be wondering how to install a floor outlet in concrete for your home or office. That’s why we’re here to give you a step-by-step guide. We will also discuss the advantages and disadvantages of floor outlets.

How to Install a Floor Outlet in Concrete in Few Steps?

Concrete floors are common in many homes and businesses. They are durable and easy to maintain, but they can be difficult to work with when it comes to adding new features such as an electrical outlet.

While installation might vary depending on the make and model of your outlet, these general steps should give you a good idea of the process:

Tools and Materials Needed:

  • Circuit tester
  • Drill
  • Hammer drill
  • Power trowel
  • Wire brush
  • Concrete screws
  • Outlet box
  • Cover plate

Step 01: Identify the Location for the Outlet

The first thing you need to do is identify where you want the outlet to go. Keep in mind that outlets should be placed at least 12 inches away from any water source, such as a sink, bathtub, or shower.

They should also be placed away from any sources of heat, such as a stove, fireplace, or radiator. Once you have chosen the location, mark it with a pencil so you know where to drill.

Step 02: Drill a Hole for the Outlet Box

Drilling a hole for a floor outlet is a straightforward process, but there are a few things to keep in mind.

First, the size of the hole will need to be slightly larger than the diameter of the outlet box. Second, the hole should be at least two inches deep to ensure that the electrical floor outlet will be flush with the floor. Finally, it is important to use a carbide-tipped drill bit to avoid damaging the concrete.

With these guidelines in mind, simply attach the drill bit to your drill and slowly begin drilling into the concrete. Once the hole has been drilled, use a wire brush to remove any loose debris.

Step 03: Cut a Hole for the Wires

The next step is to cut a hole. You’ll need a hammer drill with a concrete-cutting bit, and you’ll also need to rent a power trowel. Start by drilling a hole in the center of the area you wish to have an outlet.

Wires should be able to pass through the hole. Next, use the power trowel to smooth out the hole. Finally, insert the wires into the hole and secure them with cable clamps. Once the wires are in place, you can begin installing the floor outlet.

Step 04: Install the Box

After that, it is to install the box. First, insert the box into the hole you drilled in Step 2. Next, use screws to secure the box to the concrete. Be sure to use concrete screws, as regular wood screws will not be able to penetrate the concrete. Once the floor box is secure, you can begin attaching the outlet.

Step 05: Install the Outlet

The outlet installation process will vary depending on the type of outlet you are using. However, the basics are the same. First, connect the black wire to the brass screw and the white one to the silver screw.

Next, tighten the screws until they are snug. Be careful not to overtighten them, as this could damage the wires. Finally, connect the ground wire with the green screw. Then you can install the cover plate.

Step 06: Attach the Cover Plate

After the outlet box is properly mounted and wired, it’s time to attach the panel cover. Start by screwing the plate onto the receptacle box, then tighten it down with a Phillips screwdriver. Make sure it is flush with the surrounding floor, then use a power drill to screw it into place.

You can also use concrete screws to secure the cover plate. Once that plate is in place, your floor outlet is ready to use.

Step 07: Test the Outlet

Now that you have successfully installed your floor outlet, it is time to test it out. First, plug in a lamp or other device to the outlet to make sure that it is receiving power. Next, use a circuit tester to check the ground wire connection.

Finally, check that all switches in the circuit are energized to ensure that the outlet is connected properly. If everything is working correctly, you can now use the additional outlet.

These are the basic steps for putting in a concrete floor outlet. With a little bit of patience and attention to detail, you can easily add an extra outlet to any room in your home. And make sure to have all the tools you need with you and read all the instructions carefully before starting the project.

What are the Advantages of Using a Floor Outlet?

Metal floor outlets

Floor outlets not only provide an extra measure of convenience, but they can also be a safety hazard. If you have young children or pets, a floor outlet can be a potential choking hazard.

That’s why it’s important to use tamper-resistant outlets whenever possible. These outlets have special covers that prevent small objects from being inserted into the sockets.

Another advantage of using floor outlets is that they can help you save space. With so many electronic devices, you may find that having an electrical outlet on the floor frees up valuable counter space.

Finally, floor outlets can be used to hide unsightly cords. If you have a television or other device that you want to keep out of view, installing an outlet is a great way to keep the cords hidden and out of the way.

What Are the Disadvantages of Using a Floor Outlet?

While there are many advantages to using a floor outlet, there are also some disadvantages:

First, they can be a trip hazard. If you have a lot of people walking around your home, you may want to consider installing outlets at a higher level to avoid any potential accidents.

Second, floor outlets can be difficult to install. If you’re not familiar with electrical work, it’s best to hire a professional to install the outlet for you.

Floor outlets are also a bit more expensive than traditional outlets. But if you consider the convenience and safety they offer, they may be worth the extra cost.

Frequently Asked Questions

Not every home is the same, and that means not every outlet installation will be the same either. Here are some frequently asked questions about installing floor outlets:

1. Are Floor Electrical Outlets Safe?

Yes, but it’s important to make sure that they are covered when not in use in order to avoid any damage to the outlet itself or causing any electrical problems. In fact, properly covering the electrical outlet on your floor may even prevent a fire.

2. Can a Rug Go Over a Floor Outlet?

It is ok to cover it with a rug as long as the outlet is not being used. If you are going to use it, make sure that the rug is not in the way and that it does not cover the electrical outlet box. You should also never cover an outlet with any type of flooring that is permanent, such as wall-to-wall carpet.

3. Do Floor Outlets Need to Be GFCI?

NO. You don’t need floor outlets to be GFCI. But if they are in an area that is considered “wet or damp” (such as a bathroom, kitchen, or laundry room wall outlet), then they should be GFCI-protected. This is for your safety, as GFCIs help prevent electrical shocks.


Installing a floor outlet is a relatively easy project that can be completed in a few hours. Just make sure you have the right tools and materials, and take your time to ensure that the outlet is installed correctly. Once it’s in place, you’ll enjoy the convenience of adding an outlet to your room.

By following the guidelines provided in this article, you will make it easy for yourself. After that, you will have an outlet on your floor that is both safe and convenient to use. Hope this article will be helpful for you. Thank you for your time.
