Bathroom Mirror & Shaving Cabinet Guide: Sizing, Lighting & Recessing

Choose mirrors, LED mirrors and shaving cabinets by size, storage and lighting needs.

The mirror wall is the visual centrepiece of your bathroom. Beyond reflection, it is your daily grooming workstation and one of your best opportunities to incorporate layered lighting and hidden storage. Here is how to choose the right style, size, and electrical configuration for your renovation.

1. Mirror Sizing Rules of Thumb

To create a balanced vanity wall, use these standard design guidelines:

  • Match or inset slightly: Your mirror should either match the exact width of your vanity or sit slightly narrower (inset by 50mm to 100mm on each side). A mirror wider than the vanity makes the room feel top-heavy.
  • Double vanity options: For 1500mm or 1800mm double vanities, you can either install one continuous wide mirror across the entire length, or two individual mirrors centered directly over each basin.
  • Eye-level positioning: Position the centre of the mirror roughly 1500mm–1600mm above finished floor level to accommodate family members comfortably.

2. Flat Mirror vs Shaving Cabinet: Storage vs Slimline

  • Plain or Framed Mirrors: Slimline, minimalist, and sits completely flat against the wall tiles. Ideal for powder rooms or bathrooms that already have generous vanity drawer storage.
  • Mirrored Shaving Cabinets: Combines a full-sized mirror front with multi-tier shelving behind. Perfect for keeping medicine, cosmetics, and toothbrushes hidden away from wet benchtops.
  • Recessed installation: Ask your builder to frame out a wall cavity so the shaving cabinet can be recessed flush with the tiles, giving you deep storage with the slim profile of a standard mirror.

3. Illuminated LED Mirrors: Warm Glow & Demister Pads

Modern LED mirrors elevate bathroom functionality with built-in grooming features:

  • Built-in demister pads: Heated element pads behind the glass prevent the mirror from fogging up after a hot shower.
  • Front-lit vs Back-lit: Front-lit LED mirrors provide bright, shadow-free illumination ideal for makeup and shaving. Back-lit mirrors cast a soft ambient glow across the tiles for night-time ambience.
  • IP44 Electrical Safety: Always ensure illuminated mirrors carry an IP44 moisture-resistance rating and are hardwired by a licensed electrician.
