How to Hang and Wire an LED Mirror
Part of our Mirrors & Lighting guides.
LED mirrors are heavy glass with electrical parts. Have two people for large sizes. Hardwiring should follow local code. Turn off the water (and power at the breaker for anything electrical) before starting, and follow the product manual where it differs from these general steps.

| Difficulty | Moderate |
| Tools | Stud finder, level, drill, wire nuts, voltage tester |
Step by step
- Plan height. Bottom 5-10 inches above the faucet; center near eye level.
- Find studs. Mark studs; use rated anchors elsewhere.
- Turn power off. At the breaker; confirm with a tester if hardwiring.
- Mount brackets. Level and screw the brackets/Z-clips.
- Connect wiring. Connect line, neutral and ground per the manual, or route the plug.
- Hang the mirror. Lift onto the brackets with a helper.
- Test. Restore power and test dimming, color and anti-fog.
Tips & common mistakes
- Large mirrors (36x60, 36x72) need two people.
- Leave enough wire slack to hold the mirror while connecting.
Hardwired or plug-in?
Hardwiring hides the cord and usually uses the junction box from the old vanity light; the mirror's wires connect inside the box and a cover plate goes over it. A plug-in mirror needs an outlet behind or near the mirror; some homeowners have an electrician add a recessed outlet behind it for a clean look.
Positioning the box
An old vanity light box usually sits above where the mirror will hang. Check the mirror's wire exit location and length: if the box is outside the mirror's footprint, you'll need a blank plate or to move the box. Plan this before you mount brackets.
Heavy mirrors
Large sizes are heavy and awkward. Use studs for at least one bracket screw on each side where possible, or heavy-duty anchors rated well above the mirror's weight. Two people should always lift and hang mirrors over 36 inches wide.
Setting it up after installation
- Set your preferred color temperature (many mirrors remember the last setting).
- Test the anti-fog after a hot shower; the pad needs a minute or so to clear the glass.
- Clean with a soft microfiber cloth and glass cleaner sprayed on the cloth, not directly on the mirror edges where electronics sit.
Frequently asked questions
Can I replace a vanity light with an LED mirror?
Yes, the light's junction box often powers the mirror; a blank cover plate may be needed.
Can I install an LED mirror without an electrician?
Plug-in mirrors are DIY-friendly; hardwiring should follow local code.
How do I hide the cord?
A recessed outlet behind the mirror hides plug-in cords.
What anchors should I use?
Studs where possible, otherwise heavy-duty anchors rated above the mirror's weight.
Can I mount an LED mirror on a tile backsplash?
Yes, drilling with a tile bit.
