You can add lighting behind a round mirror using a compatible lighting system designed for a curved installation. For a bathroom, a purpose-built illuminated mirror is often the cleaner, simpler choice. It combines the mirror, lighting, controls and mounting arrangement instead of leaving you to adapt separate parts.
First decide what you want the light to do. A soft halo behind the glass looks inviting, but it does not direct light towards your face in the same way as a front illuminated border. That distinction matters more than how many LEDs fit around the circle.
Choose the effect before buying a lighting kit
- For a floating halo, plan lighting behind the mirror with enough space for the glow to reach the wall.
- For makeup and shaving, look for light towards the reflection or add suitable vanity task lighting.
- For both atmosphere and grooming, compare a mirror with front and rear illumination.
Our guide to lights behind a mirror explains the rear-lighting approach. If you are updating a dressing table rather than a bathroom wall, read what makes a Hollywood mirror different or browse Hollywood makeup mirrors for front-facing bulb designs.
What a round-mirror retrofit needs
Measure the mirror diameter and inspect the rear mounting space before choosing a system. LED tape does not bend freely in every direction: the manufacturer must allow the curve and mounting orientation you need. A strip that twists away from the backing will not produce an even halo or a tidy installation.
Use a matched strip, driver and control system, with a suitable mounting surface and cable route. Follow the supplied limits for bends, ventilation and any permitted cut points. Avoid improvising joins or covering the driver behind a sealed backing simply to hide it.
In a bathroom, the suitability of the complete installation matters. A water-resistance claim for the strip alone does not establish that its driver, joins, controls or position are suitable. Use a registered electrician for bathroom electrical installation work. A plug or extension lead is not a workaround for an unsuitable connection point.
Three ready-made round mirrors to compare
A purpose-built model gives the lighting a deliberate place in the design. These in-stock sizes offer three different reasons to upgrade.

60 cm dual-light round mirror — £128. Choose front and rear lighting when you want illumination towards the reflection as well as a glow around the wall. Dimming, three light colours and anti-fog bring useful everyday flexibility. See the round dual-light product details for other sizes.

80 cm round backlit mirror — £179. Pick this for a broad circular reflection and a softer wall glow. Three light colours, dimming, memory and anti-fog make it an attractive bathroom upgrade; keep supporting face lighting if detailed makeup is your priority.

80 cm round Bluetooth mirror — £199. Dual speakers bring music or podcasts to your morning routine, alongside illuminated glass and anti-fog. It is a more complete upgrade when you want audio as well as a new look.

Make the circle work with the rest of the room
Centre the mirror above the basin or furniture and leave space around taps, nearby shelves and wall lights. The halo needs visible wall around it to show its full effect. A highly textured or dark wall will give a different result from pale, smooth tiles, so judge the whole setting rather than copying a product photograph exactly.
For other rooms, our living-room mirror placement guide helps you decide what the glass should reflect. In the bathroom, round mirrors and complementary lighting explains how to combine the mirror with the room lighting.
Round mirror lighting questions
Will sticking lights behind a mirror make it good for makeup?
It creates a rear halo. For clearer face lighting, choose front illumination, a dual-light model or separate suitable vanity lights.
Can I add a demister with the same lighting strip?
No. Anti-fog heating is a separate function. Choose a mirror with an integrated demister if a clearer post-shower reflection is part of the upgrade.
