Small Bathroom? 9 Mirror Tricks to Make It Feel Twice the Size
Sam MallockContents
A mirror positioned to catch and reflect natural light, sized close to the full width of the wall rather than undersized, and finished without a heavy frame, does more to make a small bathroom feel bigger than almost any other single change. Beyond that, shape, height, lighting and a few smaller details compound the effect.
At a glance
- Position a mirror to catch natural light from a window wherever the layout allows.
- Don't under-size a mirror in a small room; close to full wall width generally works better than a smaller one.
- Frameless or slim-edged designs maximise genuine reflective surface area.
- Round mirrors soften hard-edged small bathrooms; backlit LED designs add depth as well as brightness.
- Keep the wall around the mirror uncluttered so its space-enhancing effect isn't undermined.
Small bathrooms and cloakrooms don't have to feel cramped. In most cases, the mirror is doing far less work than it could be, either through poor positioning, an undersized frame, or simply being treated as an afterthought rather than the single biggest space-enhancing feature in the room. Here are nine ways to fix that.
1. Position it to catch natural light
If your small bathroom has a window, the single most effective placement is a mirror on the wall facing it, so the mirror catches outdoor light and throws it back into the room. This genuinely adds a sense of depth and view that a windowless wall can't replicate, and it's worth prioritising over other placement considerations where the layout allows for it.
2. Go close to full wall width, not smaller
It's a common instinct to under-size a mirror in a small room, but a mirror close to the full width of the basin or available wall reflects considerably more light back into the space than an undersized one. A larger mirror, positioned correctly, tends to make a small bathroom feel bigger, not smaller.
3. Choose a frameless or slim-edged design
A heavy, thick frame reduces the actual reflective surface area and visually competes with the room around it. A frameless or slim-edged mirror maximises the amount of genuine reflection on the wall, which matters more in a small space than in a larger room where a statement frame has room to breathe.
4. Consider a round shape to soften hard lines
Small bathrooms tend to be full of hard edges: square tiles, straight vanity units, boxy storage. A round mirror breaks up that geometry and tricks the eye into reading the space as softer and, often, wider than it is. See our guide to round vs rectangular mirrors for more on when each shape suits a room.
5. Mount it at the right height, and consider going taller
Centring a mirror at roughly eye level, and choosing a slightly taller format where the wall allows, draws the eye upward and enhances the sense of vertical space. For guidance on matching mirror dimensions to your basin and wall, see our size guide.
6. Add backlit LED lighting for depth, not just brightness
A backlit mirror, like AURA's round HALO, throws a soft halo of light onto the wall behind it, which adds a sense of depth to a flat surface that a plain mirror can't achieve on its own. This is one of the few upgrades that improves both the room's lighting and its perceived size at the same time.
7. Use natural white light to enhance reflective surfaces
Cooler, natural-toned light around 4000K tends to enhance the reflective quality of tiles, glass and mirrors more effectively than warm amber tones, adding to the sense of brightness and openness. AURA's GLOW and HALO both include this setting alongside warmer and cooler alternatives.

8. Consider a mirrored cabinet to combine storage and reflection
If a small bathroom is genuinely short on storage, a mirrored cabinet does double duty: it keeps clutter off visible surfaces (clutter itself makes small rooms feel smaller) while still providing a large reflective surface. Where wall space is at a premium, this combined approach is often more practical than a plain mirror plus separate storage elsewhere. Our guide to LED mirror or mirror cabinet compares the two.
9. Keep the wall around it uncluttered
However well the mirror itself is chosen, its space-enhancing effect is undermined if the wall around it is crowded with shelves, bottles or fixtures. A clean run of wall either side of the mirror lets it do its job of reflecting light and space, rather than competing with visual clutter for attention.

Frequently Asked Questions
What is the best mirror shape for a small bathroom?
Round mirrors tend to soften the hard lines common in small, tiled bathrooms and can make the space feel less boxed-in, though a slim-edged rectangular mirror sized to the full width of a wider wall also works well.
Should a small bathroom mirror be large or small?
Larger, within reason. A mirror close to the full width of the basin or available wall reflects more light back into the room than an undersized one, which tends to make a small bathroom feel bigger rather than more cramped.
Does a backlit mirror help a small bathroom feel bigger?
Yes. A backlit mirror adds a halo of light to the wall behind it, giving a flat surface a sense of depth that a plain, unlit mirror doesn't provide, on top of its practical lighting benefit.
Where should I position a mirror in a small bathroom?
Facing a window, if there is one, is the single most effective position, since it reflects natural light and an outward view back into the room. Where no window is available, prioritise a wall where the mirror can be sized generously without obstruction.
