LED Bathroom Mirror Buying Guide: Size, Light, Anti Fog

The right LED bathroom mirror starts with your vanity width. Pick a mirror a little narrower than the vanity (or one mirror per sink on a double), then decide how you want the light to come out of it, whether you need a defogger and dimmer, and whether it will be hardwired or plugged in. This guide walks through each choice and compares the LED mirrors we carry, using only the specs on our product pages.

LED bathroom mirror sizing: match it to the vanity

Our bathroom vanity sizes guide uses a simple starting point: a mirror a little narrower than the vanity, or one per sink on a double vanity.

Some quick examples using sizes we actually list:

  • 24 in vanity: an 18 or 20 in wide mirror, such as the 18×36 Blossom Stellar LED M4 or the 20×32 Blossom Binary LED M5.
  • 30 in vanity: a 24 in mirror, which most of the Blossom lines offer.
  • 36 in vanity: a 30 in mirror.
  • Double vanity: two mirrors, one centered over each sink.

Our Blossom listings give sizes as two numbers, such as 24×36. We read these as width by height in inches because the first number is the one that changes across sizes, but confirm before you order, since the listing does not say.

For height, Lamps Plus suggests in its guide to buying and hanging a mirror placing the mirror a few inches above the sink to avoid backsplash. If you also plan a light bar above the mirror, our bathroom vanity light size guide covers fixture width and mounting height, and our wall sconce height guide covers lights beside the mirror.

Backlit, front lit or frosted edge?

Where the light exits changes the look:

  • Backlit: LEDs behind the glass wash the wall with a soft halo. Good for ambiance, less direct on your face.
  • Front lit: light shines toward you through frosted bands or a frosted border. Better for shaving and makeup.
  • Both: some mirrors combine a frosted front band with a backlight.

Two of our Blossom lines name the frosted edge in the title: the Beta LED Mirror with Frosted Sides (LED M2) and the Orion Round LED Mirror with Frosted Side (LED M3). The ANZZI Ether cabinet lists a 40mm inside frosted panel. The other listings do not say where the light exits.

Lighted vanity mirror features worth checking

Color temperature and dimming

Warmer white feels relaxed; cooler white reads cleaner. Our vanity light guide lists the Kelvin and CRI ranges that lighting retailers recommend for bathrooms. A dimmer is worth having if the mirror is your main light at night. The ANZZI Ether lists a dimmer you control with its touch sensor.

Anti fog mirror defogger

A defogger is a heating pad behind the glass that keeps a patch of mirror clear after a shower. The ANZZI Ether 28 in. x 32 in. LED mirror cabinet lists a built in defogger. Our Blossom listings do not mention one, so confirm before you buy.

Touch controls and memory

Most LED mirrors use a touch sensor on the glass for on/off and dimming. Memory (the mirror returns to your last brightness or color) is a nice extra, but none of our current listings state it, so treat it as unconfirmed.

Damp ratings and IP codes

None of the listings below state an IP or damp rating, so ask for the spec sheet if the mirror will sit near a shower. Our vanity light guide covers damp and wet ratings.

Wiring: hardwired or plug in

LED mirrors are either hardwired to a junction box behind the mirror or plugged into an outlet. Hardwired has no visible cord; the ANZZI Ether lists a 1.6m hardwire connection. Plug in is simpler but needs a nearby outlet. Our Blossom listings do not state which type each model is.

Either way, a licensed electrician and your local code have the final word on bathroom wiring. We cover the details for lighted cabinets in our recessed vs surface mount medicine cabinet guide.

Shape and mounting orientation

Rectangles are the most flexible, and many can hang tall (portrait) or wide (landscape). Portrait suits a single sink and a taller view; landscape suits a wide vanity or a low ceiling. Confirm a mirror can rotate before you plan on it. Round and oval mirrors, like the Blossom Oval LED M6 (20×30 or 24×36) and the Orion Round (24 or 32 inch), soften a room with a lot of straight lines.

For hanging, the Lamps Plus guide lists a pencil, stud finder, level and screwdriver, and suggests a second person to help position the mirror. Use anchors rated for the weight; the ANZZI Ether lists 56.55 lbs.

LED mirror vs lighted medicine cabinet

A flat LED mirror is thinner and simpler to hang. A lighted medicine cabinet adds storage: the ANZZI Ether has double doors, an aluminum cabinet and tempered glass shelves, plus the defogger and dimmer. If your vanity already has plenty of drawers, a flat mirror keeps the wall clean.

H, and the Glossy White 84 in. double vanity with 36 in. LED mirrors ($2,091.99) includes mirrors at 36 in. W x 32 in. H. Both vanities arrive fully assembled, and the top is sold separately. Their listings do not describe the mirrors’ lighting features.

Frequently asked questions

What size LED bathroom mirror do I need?

Go a little narrower than the vanity: roughly 18 to 20 in for a 24 in vanity, 24 in for 30 in, 30 in for 36 in. On a double vanity, use one mirror per sink.

Is a lighted vanity mirror bright enough to replace a vanity light?

In a small powder room it can be, especially a front lit model. In a main bathroom, most people add a light bar or sconces.

Do I need an anti fog mirror?

If the mirror fogs after every shower, a defogger saves wiping. Check the listing: the ANZZI Ether states one, while our Blossom listings do not mention it.

Does an LED mirror need an electrician?

A plug in mirror only needs an outlet. A hardwired mirror connects to a junction box, and a licensed electrician and local code have the final word on that work.
