Yes, a vanity light can project in front of a mirror or extend beyond its sides. The useful test is whether the fitting lights your face comfortably, clears the mirror and any opening cabinet door, and looks balanced above the basin. There is no single overhang measurement that suits every bathroom.
Before choosing a fitting, decide which kind of overhang you mean. A wide light bar and a deep projecting shade create different problems, even when both are described as “overhanging the mirror”.
Width, projection and height: measure all three
On a small screen, swipe the table to compare all columns.
| Measurement | What to check | Why it matters |
|---|---|---|
| Width across the wall | Compare the fitting with the mirror, basin and usable wall width. | A wider fitting can work, but should look intentional rather than cramped against a side wall. |
| Projection from the wall | Measure to the front of the shade and the mirror or cabinet. | A projecting fitting can obstruct an opening cabinet door or dominate the reflection. |
| Height above the mirror | Allow the fitting its required clearance and check it from your standing position. | A bare lamp reflected at eye level can be uncomfortable even when the fitting looks well centred. |
Tape the mirror outline on the wall and mark the proposed fitting position. Stand where you brush your teeth or shave, rather than judging only from the doorway. With a mirror cabinet, include the full door-opening arc in your measurements.
Aim for comfortable face lighting
An overhead fitting can be attractive and practical, but its position may create shadows beneath the brow or chin. Side lighting or an illuminated mirror brings light from a different direction. A frontlit mirror is particularly useful when you want the light near the reflection without making room for two wall lights.
A backlit mirror adds a glow onto the wall behind it. That is a different effect from light directed towards your face. Combine the mirror with the room lighting and judge the result at the basin. For a closer comparison, read LED bathroom mirrors versus separate vanity lights.
Three illuminated alternatives to a projecting vanity light
40 × 50 cm frontlit mirror — £89. This is a useful starting point for a cloakroom or smaller vanity. Front lighting, three colour settings and anti-fog bring everyday convenience into a compact shape.
80 × 60 cm gold-framed frontlit mirror — £159. Choose this for a wider single vanity and a defined metallic edge. Dimming lets you soften the illumination as the room changes from morning routine to evening use.
140 × 70 cm extra-large dual-light mirror — £299. A generous reflection for a larger vanity, combining front lighting, backlighting, dimming and anti-fog. It offers a different route from hanging several fittings around a broad mirror.

Match the shape to the rest of the bathroom
A rectangular mirror makes it easy to align a light bar with the furniture below. A round mirror softens straight tile lines; round mirror lighting ideas show how that changes the wall composition. For a more sculptural look, irregular mirrors work best when the surrounding fittings leave their outline room to stand out.
Choose the light colour for the room and the task rather than treating one setting as universally correct. Warmer light creates a softer mood; a more neutral or cooler setting can be useful while getting ready. Dimming is a separate adjustment: it changes brightness, not colour tone.
Plan the installation before ordering
Measure the available width, fitting projection, cabinet clearance and supply position before the wall is finished. Use our LED bathroom mirror installation guide to prepare the layout. Have bathroom electrical installation work carried out by a registered electrician, as recommended by Electrical Safety First.
For a separate dressing-table setup
A bedroom vanity has different needs from a bathroom wall. Makeup mirrors with built-in lighting bring the light closer to a seated routine, while Hollywood mirrors create a bulb-framed focal point. Read what a Hollywood mirror offers or our wall-mounted makeup mirror installation guide when planning that space.
Vanity light placement questions
Must the light be narrower than the mirror?
No. A wider fitting can look balanced when it suits the basin and wall. Check its visual proportions and the light at your face, rather than following a fixed width rule.
Can a vanity light sit above a mirror cabinet?
Yes, with adequate clearance for the cabinet and its opening door, and a fitting suitable for the installation position. Measure the projection as well as the height.
