Add Floor Outlets
Floor outlets solve the age-old problem of powering lamps and electronics on furniture that floats in the center of the room. Without them, you're stuck running extension cords across the floor or pushing sofas against walls. A few strategically placed floor outlets give you complete freedom in furniture layout.

Where to Place Floor Outlets
Map your furniture layout first
Floor outlets only work if they land under or right next to a piece of furniture. Place one under the end table position next to a floating sofa for lamps. Place another near the center of a seating arrangement for a floor lamp. Use painter's tape on the subfloor to mark furniture footprints before committing.
Consider future flexibility
Furniture arrangements change. Place floor outlets at logical intersection points that work with multiple layouts. Common placements include the center of the room, 3 feet in front of the fireplace (for side tables flanking a sofa), and near window walls where a desk or reading chair might go.
Account for the subfloor construction
Floor outlets are easiest to install over a basement or crawl space where wire can be routed from below. Slab-on-grade construction requires cutting a channel in the concrete, which is more invasive and expensive. Over a basement, the electrician drills through the subfloor and runs Romex through the joists below.
Floor Box Types
- Flush-mount brass cover ($30-$80): The most popular option. A round or rectangular brass plate sits flush with the finished floor. The hinged lid flips open to access the outlets. Available in brass, nickel, and dark bronze to match your hardware.
- Pop-up floor outlet ($50-$150): Sits below the floor surface when not in use and pops up when you press or twist the cover. Provides a completely flat surface when closed. Ideal for areas with foot traffic.
- Recessed floor box with cover plate ($40-$100): A deeper box that accommodates standard duplex outlets plus data ports. The screw-down cover plate provides a watertight seal when closed. Best for high-end hardwood floors.
- Multi-service floor box ($80-$200): Combines power outlets with USB charging ports, HDMI pass-through, or Cat6 ethernet. Perfect next to a media console or home office area in the living room.
Installation Considerations
- Waterproof covers required: NEC code requires floor outlets in finished living spaces to have listed covers that are either waterproof or intended for dry locations, depending on the floor type.
- Flush with finished floor: The box and cover must sit perfectly flush with the finished flooring surface. Install the box during the subfloor phase and adjust the height after the finish flooring is installed.
- Coordinate with the flooring installer: The flooring crew needs to know exact box locations so they can cut precise openings around each outlet. Poor coordination results in visible gaps or a cover that won't sit flat.
- Dedicated circuit recommended: If you plan to power a media center or space heater from a floor outlet, run a dedicated 20-amp circuit to avoid tripping breakers.
Pro Tips
- •Install during the subfloor phase: Floor outlets are easy and cheap to add before the finish floor goes down. Retrofitting them into an existing hardwood or tile floor costs 3-5x more and risks damaging the finished surface.
- •Two is usually enough: Most living rooms benefit from 1-2 floor outlets. Over-installing creates tripping hazards and unnecessary cover plates in visible areas. Place them where they'll be hidden under furniture.
- •Match the cover to your floor finish: Brass covers work with warm-toned wood. Nickel or dark bronze covers pair with gray or dark floors. A matching cover becomes nearly invisible once furniture is in place.
