A bathroom mirror cabinet needs a fixing plan for the wall, its fully loaded weight and its opening doors. Choose the cabinet and mounting method first, then set a comfortable viewing position, locate hidden services and fit the specified brackets and securing points. An illuminated model also needs an appropriate power connection.
If your goal is a tidier basin, explore our bathroom storage ideas and mirror cabinet range. The right cabinet brings daily essentials within reach without crowding the worktop.
1. Choose surface or recessed mounting
Surface-mounted cabinets project from the wall. Recessed models need an opening and sufficient suitable wall depth. Do not cut a recess for a cabinet designed only for surface mounting, or use the front mirror dimensions as the cut-out size.
The 500 × 700 mm non-illuminated cabinet supports surface or recessed mounting. Its drawing specifies a 48 × 68 cm recess with at least 10 cm depth. Match the actual unit and installation drawing before cutting, and arrange any structural or services work first.
2. Compare depth and door clearance

50 × 70 cm frontlit Bluetooth cabinet — £269. Its 13 cm overall depth brings illuminated reflection and storage together. Allow clearance above the tap and to the side for the door.

80 × 70 cm dual-speaker cabinet — £369. The cabinet body is 12 cm deep and its shelves are 10 cm deep. The unequal doors need different opening clearances; do not assume two equal 40 cm panels.

50 × 66 cm walnut-effect cabinet — £169. Overall depth is 14 cm, including the 2 cm front section. The sensor light illuminates the cabinet interior; it is not mirror-face lighting. Battery lighting does not remove the need for secure wall fixings.

3. Set the height around actual use
Mark the cabinet outline with removable tape and check the reflection while standing at the basin. Include the shortest regular user, the tap height, shelf access and the opening door. A single floor-to-cabinet measurement cannot suit every bathroom.
Use a level and the model’s fixing template or actual bracket positions to mark the installation. If replacing an existing unit, read mirror-cabinet replacement planning rather than assuming the old holes match.
4. Assess the wall and hidden services
Establish whether the wall is masonry, plasterboard on framing or another construction, and check for pipes and cables before drilling. Select the fixing system for that wall and the loaded cabinet, not just its empty weight. A plasterboard plug is not automatically an adequate substitute for structural support.
Our heavy-mirror fixing guide explains the wall-assessment questions. If drilling is restricted, read the limits of no-drill cabinet mounting before buying; adhesive-only mounting is not a general alternative for a loaded cabinet.
5. Fit the specified hardware and secure the cabinet
Follow the supplied bracket, rail or fixing arrangement, including any lower securing points. Drill for the selected fixings using the appropriate method for the wall finish. Use a level before final tightening and protect the basin and floor from tools or dropped fittings.
Arrange enough help to lift and hold the cabinet safely. Seat it fully on the mounting system and engage every required retaining fixing. Do not leave it supported only on a temporary hook while fitting shelves or adjusting doors.
6. Complete power and final checks
Have a qualified electrician complete hardwired bathroom connections and assess the intended electrical location. A mains-powered cabinet, a battery-lit cabinet and an unlit cabinet have different requirements. Keep the manufacturer’s ventilation and access clearances.
Fit shelves and door fittings as instructed, check smooth opening and closing, and confirm the cabinet is secure before loading it. Keep within the stated shelf and storage limits. Clean the mirror with a soft cloth and compatible cleaner, then dry the edges.
Make the storage work for you
Place frequently used toiletries where you can reach them comfortably, leaving room to lift bottles out rather than filling every gap.

A well-positioned cabinet should make the morning routine easier, with the mirror, doors and shelves all comfortable to use.
