Everything You Need to Know About Floating Vanities was a popular post of ours last year. You all loved how we took this seemingly simple subject and unpacked all the little decisions behind it that really make a difference in your space. Which is why this time, we are focusing on detail that gets FAR less recognition than it deserves: your rectangular frameless led bathroom mirror.
Come on now — what type of bathroom mirror should I get? This is one of the most frequently asked questions when people begin designing (or re-designing) their bathroom. But honestly? That is the way most people do it but they are wrong. Why? Because they only care for aesthetics, when they should be focusing on scale, function, & how the mirror affects the feel + routine of the bathroom.
So let's break it all down. Whether it is dimensions, lighting, or a style pairing — we cover it all.
THE MIRROR: THE STATEMENT PIECE OF YOUR BATHROOM
Now, imagine your bathroom mirror — it is not something you look at every morning. This is the art — visually the focal point of the space; akin to your kitchen backsplash or your living room fireplace.
Your mirror plays a massive role whether you are designing a bright, energizing space to kick-start your day or a chill, spa-like retreat for winding down. Particularly if there is no frame and if it is LED-illuminated. Why? Since this mirror style is not competing against a large frame, or decor that doesn't match. It flows with the wall. It glows. It lends the elevated, built-in look to your bathroom that is clean, modern + high intention.
So the question becomes:
What energy do you wish to see reflected on you every morning?
STEP ONE: SCALE — HOW BIG DOES IT NEED TO BE?

Like you would never consider a dining table without having measured the room, you don't pick a mirror without understanding scale. Well, the first one definitely is one of the biggest mistakes we see with mirrors — picking a size that's too small! It really messes with the proportions + makes even the best of vanities look out-of-place.
So here is a summary to help you nail it:
Mirror Size (in) | Best For | Pairs Well With |
---|---|---|
20" x 28" | Small powder rooms | 18”–24” vanities |
24" x 36" | Guest bathrooms | 30”–36” vanities |
30" x 40" | Primary bathrooms | 36”–48” vanities |
36" x 48"+ | Double vanities or wide walls | 60”–72” vanities or full-wall styles |
My tip for the best mirror size is to do the mirror at about 70-80% of the width of your vanity. Vertical space is also something important to consider — a tall mirror can help a room with low ceilings feel larger, too.
WHY GO FRAMELESS?

Frameless mirrors are a design tactic not just a trend - This allows you to get rid of the visual "border" of the solution.
- Give it a fresher, more spacious appearance
- Allow your wall tile or paint color to breathe
- Smaller bathrooms can feel more spacious
- No struggling with finishes (no debating whether your brass faucet plays well with a chrome frame)
On top of that, frameless mirrors work perfectly with LED lighting, as there is no bulky edge to block or diffuse the glow.
LIT VS BACKLIT: LED STYLE CHOICE
With the word LED, you likely conjure up an illuminated mirror akin to something from a futuristic hotel. Edit: But it turns out — each type is has its own feel!
Style | Features | Vibe |
---|---|---|
Front-lit | Surface-mounted or edge-lit light strips | Functional, bright, practical |
Backlit | Light glows from behind the mirror | Ambient, moody, spa-inspired |
Dual-lit | Uses a combination of both front + back lighting for total versatility | High-end, luxury hotel level |
Not sure which to choose? Here's how we break it down:
- The makeup lovers or the skincare lovers? Go front-lit.
- Want that soft glow at night? Go backlit.
- Can't decide? Ace Decor also has dual-lit options as well. Because there are times when all is possible.
FEATURES THAT ARE SMART & MAKE YOUR LIFE SIMPLE

Also, not your middle aged grandmother mirror. These days, LED bathroom mirrors come fully loaded with features that will even enhance your day-to-day life. Here are few of our top picks of Ace Decor that we completely love.
- Hands-Free Control — Touch or Motion Sensors
- Anti-fog Technology — bye bye glass wiping during shower time
- Selectable Brightness — Set the mood or kick it into task lighting
- Integrated Clocks Or Temperature Gauges — yes, really
- Eco-efficiency — uses a fraction of the power of overhead lighting
Let's just say … once you use one, there's no turning back.
INSTALLATION ADVICE: THE UNWRITTEN RULES
We know that installation can feel like the scary part. But it doesn't have to be. Here's what we recommend:
DO:
- If you are having your home hardwired, hire a licensed electrician
- Use studs or heavy-duty anchors — LED mirrors are heavier than standard mirrors
- Measure twice, hang once
- Leave at least 1.5 inches between mirror + faucet
- Ensure that your outlet is properly positioned — preferably behind the mirror
DON'T:
- Just place on uneven tile (it will sink over time)
- Hang a small mirror above a double vanity (size matters!)
- Flaunt cords or junction boxes — destroys the entire seamless situation
STYLING INSPIRATION: MATCH MADE IN HEAVEN
Now that you have your mirror basics, let's discuss the further styling — as a mirror should complement the rest of your space, not compete with it.
Spa-inspired bathroom?
Choose a backlit mirror and complement with a floating wood vanity, matte black fixtures and soft gray tiles.
Minimalist + modern?
Opt for a frameless mirror with front-lit LED, a simple wall-mounted faucet and high-gloss white or navy cabinetry.
Luxury hotel look?
Choose an illuminated mirror, a marble countertop, gold or brushed nickel fixtures and large-format tile.
Compact powder room?
Use a small-scale rectangular mirror to reflect added light, pair it with a bold wallpaper or a moody paint color, and let it shine.
DOUBLE VANITY? NO PROBLEM.

Double vanities offer flexibility — and we love that. Here are two great strategies for the layout:
- One large mirror (60”–72”): Feels generous, continuous and luxe. Ideal for couples or shared bathrooms.
- Two individual mirrors (24”–40” each): Provides symmetry + a more intimate vibe. Bonus? You can tailor the lighting levels left and right.
Either way, be sure the mirrors are perfectly aligned with the sinks — misalignment is a sure ticket to visual chaos.
FAMILY-FRIENDLY FEATURES
Got kids? Pets? A partner who always, somehow, splatters toothpaste everywhere?
We hear you — and this is what to watch for:
- Tempered glass (will not shatter easily)
- Fingerprint-resistant coatings
- Sealed from water creep into LED panels
- Rounded corners for safety
- Easy to clean, low-maintenance finishes that wipe down in seconds
At Ace Decor, we believe design should not be at the cost of durability. You deserve both.

FAQS

1. Can I set up a rectangular frameless LED mirror in a room without natural light?
Yes — in fact, that's one of the best places to use one. LED mirrors are practically made for low-light bathrooms. Because they emit constant, directional light that resembles daylight (without the glare), they're perfect for a windowless powder room or an interior bathroom with poor lighting. If you don't get natural light in your space at all, go for mirrors with adjustable color temperature — so you can toggle between bright, energizing cool tones in the morning and softer warm tones in the night. It's the closest thing there is to bringing the sun inside.
2. What if the LED lighting is not functional? Is it fixable, or does it need replacing?
We hear this one a lot — and it's a good question. The short answer is yes — most LED components are readily repairable or replaceable, but the process is model-specific. At Ace Decor, every one of our mirrors is built for serviceability. Rectangular LED Mirrors need most of the time modular lighting strips and driver systems which can be easily accessed and replaced by a licensed electrician if required. Bonus? LED lights are rated for more than 50,000 hours — so for most households that's decades of daily use before anything needs to be addressed. That being said, always check your warranty and do reach out to your installer or our team should you ever encounter an issue.
3. Tile or Backsplash On Walls: Can I Put a Rectangular LED over It? Will it sit flush?
A good one, and one many people fail to ask until install day whoops! The answer is yes — but you're going to want to plan ahead. If you're installing your mirror above tile or a thick backsplash, ensure that the wall behind it is flush and that whatever detail sticks out there (like pencil trim, grout lines or outlets) doesn't obstruct the back panel. Frameless LED mirrors typically sit 0.75”–1.5” from the wall, so they will usually float over tile for a seamless experience — but for a super flush, built-in look, we recommend waterproofing under the tile prior to installation, pre-measuring where to position anchor points on the wall to leave room for both the mirror hardware + wall depth. Our team can walk you through this — trust us, it's worth the additional planning.
