How to assemble a wardrobe with sliding doors
A sliding-door wardrobe is the biggest flat-pack job in most homes. It is built lying down and stood up at the end, so space and a helper matter as much as tools. The doors only run smoothly if the carcass is square and the tracks are level.

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: top, bottom, sides and dividers
- Back panels and joining strips
- Top and bottom door tracks
- Sliding doors with wheels and guides
- Shelves, hanging rails, cam locks, dowels and anti-tip fitting
Step by step
Step 1: Measure the ceiling height: the wardrobe must be tipped up from lying on its back, and its diagonal must fit under the ceiling.
Step 2: Build the carcass lying on its back on a soft surface, fitting the sides and dividers to the base and top with dowels and cam locks.
Step 3: Measure the diagonals of the back and push the carcass square, then fix the back panels, with any joining strips, along every edge.
Step 4: With two people, lift the wardrobe upright by walking it up from the top end, then slide it into place.
Step 5: Level the carcass with the adjustable feet or packers, checking both across and front to back with a spirit level.
Step 6: Screw the top and bottom door tracks in place, making sure they are parallel and fully level.
Step 7: Fit the rear door first: lift it into the top track, then lower it into the bottom track. Then fit the front door.
Step 8: Adjust the door wheels so the doors hang straight and meet the sides evenly, then fit the shelves and hanging rails.
Step 9: Fix the wardrobe to the wall with the anti-tip fitting.
Common mistakes
- Building the wardrobe upright, which makes it almost impossible to square.
- Forgetting to measure the ceiling, so the wardrobe cannot be tipped up.
- Levelling the doors by adjusting the wheels when the real problem is a carcass that is not level.
Safety notes
- Lifting a large wardrobe upright takes two people; lift with your legs and keep your back straight.
- Mirror doors are heavy and fragile: carry them upright with two people and wear gloves.
- Always fix the wardrobe to the wall.
