Why the old vanity light falls short
Many older bathrooms have a single bar light over the mirror. It lights the top of your head and casts shadows under the eyes and chin, which is exactly the wrong light for shaving or makeup. The fix is light that reaches your face from the sides or from the mirror itself.
Three common vanity setups
Sconces on both sides of the mirror
Wall lights on each side, roughly at face height, give the most even light. They need wall space beside the mirror, which can be tight with a narrow vanity or a mirror that runs wall to wall.
A backlit or lighted mirror
A mirror with built-in lighting lights the face evenly and saves wall space. It needs a power connection planned behind the mirror. Our Ashburn project paired backlit mirrors with a double vanity.

This double vanity with backlit mirrors is from a Bathroom Brigade project in Ashburn, not Herndon.
An overhead fixture plus a ceiling light
If side lighting is not possible, a wider fixture over the mirror combined with a ceiling light closer to where you stand reduces shadows.
Mirror size and placement
- Center the mirror on the sink, not the wall, unless the sink is centered too.
- Plan the mirror height around the people who use it most, including shorter family members.
- With a double vanity, decide between one long mirror and two separate mirrors before placing the lights.
- A recessed medicine cabinet can serve as the mirror and the storage at once; check the wall for pipes and ducts first.
Light in the shower
A shower with a glass panel may borrow enough light from the room. A shower with a solid wall or curtain usually needs its own fixture, and it must be rated for a wet location. A lighted niche is a nice addition if it is planned with the electrical rough-in.
Light for small and windowless baths
Many Herndon townhouse and condo bathrooms are interior rooms with no window at all. In those, the ceiling light and the vanity light carry the whole room, so it is worth adding a second ceiling fixture or a light over the shower rather than relying on one fixture in the middle. A window that does exist should not be blocked by a mirror or tall cabinet; daylight is still the best light for seeing true color.
Light switches deserve a moment of planning too. Put the main switch at the door, consider a separate switch for the vanity lights, and place the fan switch where people will actually use it. A switch that is easy to reach is a fan that gets turned on.
Color and dimming
Choose lighting with a color that looks natural on skin. Many people prefer a neutral white at the vanity. A dimmer on the ceiling light or a separate low-level night light helps at night without waking everyone up.
Don't forget the fan
The exhaust fan is part of the electrical plan. The Virginia Residential Code requires bathroom exhaust to discharge outdoors, not into the attic (https://codes.iccsafe.org/content/VARC2021P1/chapter-15-exhaust-systems). A quiet fan that people actually turn on, possibly with a timer or humidity sensor, protects the new paint and grout. If the duct ends at a new exterior vent cap and your home is in Herndon's historic district, check whether that exterior change needs Town review.
Last, think about the mirror and lights together with any medicine cabinet doors: a cabinet that opens into a sconce, or a mirror that hides an outlet, is an easy mistake to avoid on paper.
Outlets and permits
Plan GFCI-protected outlets where people actually use hair tools, and consider whether a dedicated circuit makes sense. Moving fixtures and adding circuits is electrical work. Inside the Town of Herndon, electrical work needs its own permit separate from the building permit; outside town limits, Fairfax County issues it.

What is the best vanity lighting?▸
Light from both sides of the mirror at about face height, or a lighted mirror. Both reduce the shadows a single overhead bar creates.
Can you add a light in the shower?▸
Yes, with a fixture rated for wet locations, planned during the electrical rough-in.
Does a lighted mirror need special wiring?▸
It needs a power connection behind the mirror, which is planned during the remodel so no cord shows.
Why does my bathroom mirror fog so badly?▸
Usually a fan that is undersized, too loud to use or poorly ducted. Replacing it is a common part of a lighting and electrical update.
