The bathroom mirror is the surface you look at most in your home, usually twice a day, usually in a hurry. It is also the piece people spend the least time choosing. Most bathrooms end up with whatever rectangle came with the vanity.
Choosing well comes down to five decisions: how wide, what shape, whether it lights up, where it hangs, and how you will look after it. This guide takes them in that order.
1. Size it to the vanity, not the wall
Start with the sink below the mirror, not the wall behind it. A mirror that lines up with the vanity looks planned. A mirror that ignores it looks like it was hung wherever the screws happened to go.
A reliable rule of thumb:
- Keep the mirror a few inches narrower than the vanity top on each side. The counter should frame the mirror, not the other way around.
- For a double sink, pick one wide mirror or two matching ones. One wide mirror makes a small bathroom feel larger. Two mirrors suit a larger room where each person has their own station.
- Measure the clear height between the top of the backsplash or faucet and anything above it: a cabinet, a light fixture, the ceiling. That number limits the mirror's height more often than the wall does.
If you are between two sizes, go for the larger one. In a bathroom a mirror that is slightly too big almost always looks better than one that is slightly too small, because the reflection carries on the lines of the room.
Every mirror we make comes in several standard sizes. If none of them fits your vanity, we can make one to your measurements.
2. Pick a shape
Rectangles line up with tiles and cabinets. They are the safe choice in a bathroom full of straight edges, and for the same reason they tend to disappear.
Round and oval mirrors soften a room built from right angles. They work well over a single sink and when a room has one strong feature, such as a patterned tile or a freestanding tub, that you want to keep in focus.
Organic and asymmetrical shapes do the most with the least. An irregular outline breaks up the grid of tiles and gives the eye somewhere to rest. We wrote more about why curves work in Organic Shapes in Home Design. In a small bathroom, an organic mirror that runs taller than it is wide draws the eye upward and makes the ceiling feel higher.
Proportion matters as much as outline. A wide, close-to-square shape such as Soho covers a double sink without a second mirror. A compact shape such as TS is made for vanities where space is short. A narrow, tall shape such as Sym suits a single sink or the gap between a sink and a window.
3. Framed, frameless or backlit
Framed mirrors bring color and material into the room. A black frame sharpens a pale bathroom. Brass or gold warms up gray stone. Our wood frame bathroom mirrors have the glass recessed into a lacquered frame, and the surfaces that sit against the wall are varnished, so no bare board is exposed. A framed mirror in a bathroom asks for a little more care: wipe the frame dry rather than leaving splashes on it.
Frameless mirrors let the shape do the work. The polished glass edge is the outline, and the mirror sits flush against the wall. Kiev is a good example: glass and nothing else. Frameless pieces suit minimal bathrooms and rooms where a frame would compete with the tiles. See all our frameless mirrors.
Backlit LED mirrors put the light behind the glass, running along the whole edge, so it comes from the mirror itself rather than from a fixture above your head. That gives you even light on your face with fewer shadows under the eyes and chin, which is why backlit mirrors have become the default over the vanity. Browse our LED bathroom mirrors.
4. LED light: warm or cool
If you choose a backlit mirror, you also choose the color of its light. Ours come in warm white or cool white, chosen when you order.
- Warm white is closer to morning sunlight. It is kinder to skin, and it is what most people want in a bathroom they also use to unwind at night.
- Cool white is crisper and brighter-looking. Some people prefer it for a sharp, clinical check in the morning, such as shaving or contact lenses, and it suits very modern bathrooms with white and gray finishes.
If you are unsure, choose warm. We explain the reasoning, room by room, in Warm vs. Cool LED Mirror Light, Explained. If you are still deciding whether you need a lit mirror at all, read LED Mirror vs. Regular Mirror.
Plan the power before you order. Backlit pieces such as Soho and TS come with a plug-in cord and an in-line switch on the cable, and run on 110–220V. There is no hard-wiring into the mirror itself, but a bathroom is a wet room, and the outlet you plug into matters. Bathroom outlets should be GFCI outlets, placed away from the splash zone around the sink and shower. Before you order, check local code and your existing wiring, and use a licensed electrician if you need a new outlet or are not sure what you have. Once the outlet is sorted, plan how the cord will run: hiding it behind the vanity or in a paintable cord cover keeps the wall clean.
5. Mounting height and placement
There is no single correct height, but two common guidelines cover most bathrooms:
- The bottom edge of the mirror should sit a few inches above the faucet or backsplash, far enough to leave room to splash without marking the glass.
- The center of the mirror should fall close to the average eye level of the people using it. In a shared bathroom, set it for the taller person. Shorter people can still see themselves; taller people cannot duck under a mirror hung too low.
For a double vanity with two mirrors, center each mirror over its own sink, not over the halves of the counter. With a single wide mirror, center it on the vanity, even if the sinks are not symmetrical.
Check the wall before you drill. Every mirror we make ships with its mounting hardware. Some pieces also leave you a choice: Sym, for example, can hang four ways. Whatever you choose, make sure the wall can carry the mirror's weight, and use the right anchors for drywall.
6. Moisture and care
Bathrooms are hard on mirrors because of steam, splashes and cleaning products. A few habits keep a mirror looking new:
- Spray glass cleaner onto the cloth, never directly onto the mirror. Liquid that runs to the edge can get behind the glass or into a frame.
- Use a lint-free cloth, and avoid ammonia-based cleaners, alcohol, solvents and abrasive pads.
- Keep the room ventilated. An exhaust fan or an open window after a shower does more for a mirror's lifespan than any product.
- On framed mirrors, wipe the frame dry. For marks, use a barely damp cloth and dry the surface right away.
7. Five mistakes we see most often
Buying for the wall instead of the sink. A mirror sized to fill the wall ends up wider than the vanity and looks as if it is floating off to one side. Measure the counter first, then the wall.
Hanging it too high. Mirrors are often hung at picture height, with the center at the eye level of someone standing across the room. Over a sink you stand close and look slightly down, so the mirror needs to come lower than you might think.
Ignoring the light above it. A ceiling light directly over the mirror throws shadows down the face, whatever mirror you choose. If you keep an overhead light, a backlit mirror or lights on either side of the mirror balance it out.
Mixing too many shapes. An organic mirror, an oval sink, round wall lights and a curved vanity in one small room start to compete. Let one or two pieces carry the curves and keep the rest simple.
Forgetting the doors. Check that a door, a medicine cabinet or a shower door does not swing into the mirror's edge. In a tight bathroom a few inches of clearance is the difference between a mirror that fits and one that gets chipped.
8. When to go custom
Standard sizes fit most bathrooms, but not every wall. An alcove, a sloping ceiling or an unusually wide vanity may need a mirror made to measure. Because every mirror we make is produced after you order it, in our own workshop in Türkiye, a different size is not a special request. It is how we work. Standard sizes take 8–17 business days from order to delivery. Custom sizes and new designs take 2–5 weeks. Tell us what you need.
Quick checklist
- Measure the vanity width and the clear height above the faucet.
- Keep the mirror a few inches narrower than the vanity.
- Pick a shape that works with your tile and fixtures, not against them.
- Decide on framed, frameless or backlit.
- If backlit, choose warm or cool light and check that you have a suitable GFCI outlet nearby.
- Mark the mounting height for the tallest regular user before drilling.
