How to assemble a bathroom wall cabinet

A bathroom wall cabinet is easy to build and harder to hang: it must hang level, on fixings strong enough for a cabinet full of bottles, away from pipes and cables in the wall. Build first, then mount it with a helper.

Tools needed

  • Cross-head screwdriver
  • Drill with masonry or tile bits
  • Spirit level
  • Pencil and tape measure
  • Cable and pipe detector

Parts to check first

Before you start, lay everything out on a soft surface (the flattened box works) and check it against the parts list in your manual.

  • Carcass panels and shelves
  • Door or mirror door with hinges
  • Hanging brackets or rail
  • Screws and wall plugs suited to your wall
  • Shelf pins or supports

Step by step

  1. Step 1: Build the carcass and fit the hinge plates and hanging brackets as your manual shows.

  2. Step 2: Choose the position and check the wall with a detector for cables and pipes, especially above and below sockets and taps.

  3. Step 3: Hold the cabinet in place with a helper, check it is level and mark the fixing holes.

  4. Step 4: Drill the holes: on tiles, start with a tile bit and no hammer action, and put masking tape on the tile to stop the bit slipping.

  5. Step 5: Insert wall plugs that suit your wall and hang the cabinet on its brackets or screws.

  6. Step 6: Hang the door and adjust the hinges so it closes evenly, then fit the shelves.

Common mistakes

  • Using the small plugs from the box in a plasterboard or hollow wall, where they will not hold.
  • Drilling tiles with hammer action on, which cracks them.
  • Hanging the cabinet where the door hits a light fitting or mirror.

Safety notes

  • Check for hidden cables and pipes before drilling.
  • Switch off the bathroom's power if you are drilling near electrical fittings, and keep water away from the drill.

This is general guidance for this type of product. Your product's own manual comes first: follow its order, fittings and torque values where they differ from this page.
