To frame a large wall mirror, choose a frame system compatible with the existing mirror, its mounting and the surrounding wall. A decorative border can make a plain mirror feel more finished, but it must not become the support for heavy glass unless the whole system is designed for that purpose.
Start by deciding whether you want to keep the current mirror or replace it with a ready-framed design. Keeping a sound mirror can preserve a size that already suits the room; replacement opens up different shapes, colours and lighting.
Check the mirror before choosing trim
- Measure the overall glass width and height, including any clips or visible brackets.
- Check for cracks, damaged edges and deterioration behind the glass.
- Confirm how the mirror is supported and how the proposed frame will fit around that system.
- Allow access to controls, sockets or nearby cupboard doors.
For an LED mirror, also preserve the designed light openings, ventilation and access points. Framing over a rear glow or touch-control area can remove the very features you enjoy. Contact the supplier before modifying an illuminated assembly rather than treating it as an ordinary sheet of glass.
Choose a suitable framing method
A purpose-made retrofit kit offers a different installation from building a new structural frame. Follow the chosen system’s measurements, materials and fixing instructions. For example, MirrorMate’s installation guidance applies to its own frame system; it is not a universal approval for any trim or double-sided tape.
If making a timber border, plan the joint style before cutting. Mitred corners are one option, but not every design uses four identical 45-degree cuts. Dry-fit the complete outline and check that it sits level without pressing on glass edges or interfering with existing supports.
Prepare, fit and allow the bond to develop
Prepare the surfaces as directed by the frame and adhesive instructions. Any adhesive must be compatible with the materials and application. Use the specified support during curing and allow the stated cure time; “finished in a few hours” is not a dependable rule for every product.
Do not remove the mirror’s original fixings because a decorative frame has been added. If the mirror needs to come down or its support needs changing, arrange suitable help for its weight and size. A large glass panel is not a one-person craft project.
Prefer a finished design instead?
54.5 × 85.5 cm black asymmetrical mirror — £79. A slim aluminium frame gives you a complete outlined shape without a separate framing project. Choose it when a softer silhouette would improve the wall.
80 × 60 cm gold frontlit mirror — £159. Combine the decorative border with adjustable illumination and anti-fog for a bathroom upgrade. Plan the electrical installation as part of replacing the old mirror.
80 cm frameless round bevelled mirror — £89. If you want a finished edge rather than a visible frame, the bevel adds detail without another material around the glass. This non-illuminated design uses the room’s existing lighting.

Match the finished outline to the room
Remember that an added frame can increase the overall footprint and reduce the visible reflection. Mark the complete new outline, including its depth, near taps, lights and cabinets. A contrasting black frame defines the wall; a warm metal finish can echo taps; a bevel keeps the palette simple.
