Our pick for a 48-inch vanity
The recommended VEVOR size fits this width with balanced margins on each side and includes front + backlit LEDs, anti-fog and three color temperatures.
If you keep a plain mirror
Add a vanity light about three-quarters of the mirror width. For this vanity, a matching VEVOR fixture is the right length.
Before you buy
- Measure the wall between obstacles, not just the vanity.
- Find the electrical box: hardwired mirrors need it behind the mirror area.
- Check that cabinet doors or a medicine cabinet won't collide with the mirror.
One mirror or a long horizontal?
For 48-inch single-sink vanities, a 36-40 inch wide mirror is the sweet spot. VEVOR's 36x48 hung horizontally (48 wide, 36 tall) matches the vanity width exactly, which some designers like for a built-in look; the 32x48 hung horizontally is the cheaper alternative.
Off-center sinks
Some 48-inch vanities have the sink offset to one side with counter space on the other. Center the mirror on the vanity, not the sink, so the wall looks balanced, unless the vanity is very asymmetric.
Lighting
A front-lit LED mirror is usually enough. If you use a separate fixture, a 6-light bar of about 40 inches fits a 48-inch vanity.
Mounting a large mirror
At this size, the mirror is heavy. Use studs for brackets where possible, and have a helper hold it while you connect the wiring.
