Install a backlit bathroom mirror by planning its position, wall support and power connection before the glass is mounted. Have a qualified electrician handle the electrical work. The practical preparation is choosing the right size, marking the intended outline and making sure the rear lighting has the space specified for that model.
A well-positioned backlit mirror gives a soft glow around the glass and a clean focal point above the basin. That effect depends on the whole installation: the wall finish, mirror spacing and surrounding lights all matter.
Start with the finished look
Measure the clear wall width and height, including taps, shelves, cabinet doors and wall lights. Mark the mirror outline at its actual size and check the reflection from the positions where it will be used. Keep the halo visible rather than crowding the mirror between projecting fittings.
Backlighting creates atmosphere around the mirror. For close shaving or make-up, combine it with suitable task lighting, or choose a design with front illumination too. Explore the backlit LED mirror collection to compare both the shape and lighting arrangement.
Three sizes and shapes to plan around
60 × 80 cm backlit mirror — £139. A generous portrait reflection with adjustable lighting and anti-fog. Measure its full footprint before locating the mounting points.
50 × 80 cm long oval mirror — £99. A narrower, curved outline for a tall basin wall. Its rear glow adds softness alongside straight tile and furniture lines.
50 × 70 cm irregular backlit mirror — £139. A more expressive silhouette for a feature wall. Allow space around the complete outline, not just the middle of the glass.

Confirm the wall and mounting arrangement
The fixings must suit the wall structure and the mirror’s actual weight. Plasterboard, masonry and tiled finishes need different planning. Locate hidden services before drilling and transfer the supplied mounting positions accurately. Do not substitute adhesive or a picture hook for the specified mounting system.
Arrange help to lift the glass and engage the brackets securely. Keep the model’s intended rear clearance: pressing a backlit mirror tightly against the wall can interfere with its mounting and lighting arrangement. Our guide to installing a large bathroom mirror covers the extra preparation needed for a broad panel. Compare large LED wall mirrors before committing to the mounting points.
Agree the electrical connection before fitting
Our bathroom mirrors can use a suitable socket supply or a direct hardwired connection, matched to the product and bathroom location. Ask the electrician to assess the proposed position, circuit protection, cable route and switching. A nearby shaver socket or ordinary outlet is not automatically suitable.
Electrical Safety First’s bathroom guidance explains why location and electrical protection matter. The electrician should safely isolate and verify the supply, complete the connection to the product instructions and carry out the appropriate checks. Do not strip and join wires by copying a generic colour diagram, and do not energise an unfinished installation to see whether it lights up.
Read our LED bathroom mirror connection guide for the information to prepare before the appointment. This keeps the work focused on the actual mirror and room rather than assumptions about an existing cable.
Check the controls at handover
Once the installation is complete, check normal operation with the installer: light colours, dimming, demister and any memory or display functions included on your model. Confirm how the wall switch interacts with the mirror controls.
A Bluetooth bathroom mirror does not necessarily need extra house wiring for its speakers. Pairing a phone is a separate setup step, explained in our Bluetooth connection guide. Use the model instructions for both power and pairing.
Keep the new finish looking good
Clean the glass with a soft cloth and a compatible cleaner applied to the cloth. Dry splashes at the edges, keep ventilation working and avoid spraying controls or electrical openings. With the position and lighting chosen well, the mirror becomes an easy, welcoming part of the daily routine.
