Assembling a Wardrobe — Assembly Instructions & Tips

The professional assembly of a wardrobe requires a systematic installation of the plinth, carcass, back panel, and doors to ensure long-term stability and precise gap alignment.

Whether dealing with a compact cupboard for the hallway or a room-filling model for the bedroom: the procedure during assembly always follows the same mechanical principles. A solid wardrobe carcass usually consists of melamine-faced chipboard or MDF, held together by specific connecting fittings. In this guide, you will learn how to structure the assembly, which tools are required, and how to avoid typical alignment mistakes.

Preparation and Checking the Scope of Delivery

Before beginning the actual assembly, thorough preparation is crucial. A large wardrobe is like an architectural puzzle – if the foundation is not precisely square, the top panel will jam in the end.

1. Sort packages: Open the boxes one by one. Always place sensitive components with decorative finishes (for example in concrete look, anthracite, or classic white wardrobe finishes) on a soft surface such as a carpet or the opened cardboard packaging to prevent scratches.
2. Check fittings: Empty all small parts into bowls. Separate wood screws, nails, wooden dowels, and cam lock connectors from one another.
3. Study the instructions: Check the manufacturer's specific manual for special features, especially for more complex constructions such as a corner wardrobe.

Required Tools for Wardrobe Assembly

To ensure a smooth process, you should prepare the following tools:

• Cordless screwdriver with matching bits (usually PZ or TX in sizes 20 or 25)
• Manual screwdriver for fine adjustments of the hinges
• Rubber mallet (for wooden dowels) and joiner's hammer (for the back panel)
• Spirit level (at least 60 cm long)
• Tape measure or folding rule
• Step ladder

Step-by-Step Assembly Instructions

The assembly time varies greatly depending on the model. A compact, 80 cm wide unit can often be assembled in one to two hours. A wardrobe 200 cm wide, which typically serves as a solution for two people, requires correspondingly more time and working area.

Step 1: Assemble the Plinth and Base Panel

Begin with the base structure. Connect the plinth fascias to the base panel. Wooden dowels and cam lock connectors are usually used here. Tap the dowels in gently using the rubber mallet. Ensure that the plinth sits completely flush. If the wardrobe has adjustable feet, screw them in now.

Step 2: Install Side Panels and Centre Partitions

Provided there is sufficient room space, the carcass is assembled lying down with the front facing downwards. Slot the left and right side panels onto the base panel and lock the connectors. For wider models from 120 cm onwards, the centre partition follows next. Tighten the screws hand-tight. Only use the cordless screwdriver with a moderate torque setting, otherwise the thread in the chipboard can strip.

Step 3: Attach the Top Panel

Place the top panel onto the standing panels. Guide the connecting bolts into the corresponding drill holes and tighten the cam lock connectors clockwise until the components pull together without gaps.

Step 4: Mount the Back Panel (Squaring Check)

The back panel is the most critical structural element of the wardrobe. It prevents the carcass from racking or collapsing. Before nailing or screwing the back panel in place, you must ensure the wardrobe is square. Measure diagonally with the tape measure from the top-left to the bottom-right corner and compare the value with the other diagonal (top-right to bottom-left). If both values are identical to the millimetre, the carcass is square. Now secure the back panel. A nail spacing of 10 cm to 15 cm is optimal.

Step 5: Stand the Wardrobe Up

This step strictly requires a second person. Carefully tilt the wardrobe upwards over the base panel. Pay attention to the ceiling height: the diagonal dimension of the side panel must be smaller than the room height, otherwise the wardrobe will strike the ceiling when being raised. Now align the standing wardrobe at its final position using the spirit level. Use small shims under the plinth if the floor is uneven.

Step 6: Install Internal Fittings

Now fit the wardrobe accessories. The side panels usually feature a row of holes in System 32 (drillings at a 32 mm pitch). Insert the shelf supports for the internal shelves at the desired height. Mount the brackets for the clothes rails and suspend them.

Step 7: Fit Doors and Hinges

The installation of the fronts differs depending on the door type:

• Hinged doors: Fasten the cruciform mounting plates inside the carcass and the hinges (usually a concealed cup hinge with a 35 mm cup drilling) into the doors. A full overlay is used when the door sits flush with the outer edge of the side panel. Mount the doors (often via a clip-on mechanism).
• Sliding doors: For a wardrobe with sliding doors, the top and bottom runner tracks must first be screwed to the carcass. Mount the running rollers onto the doors and hang the rear door into the roller guide first, followed by the front door.

Wall Fixing and Anti-Tip Protection

A wardrobe must always be secured to the wall. Especially with models featuring a shallow depth of 50 cm or an enormous height of 180 cm up to over 2 metres, there is an acute risk of tipping over when heavy doors are opened. Use suitable wall plugs and screws matched to the structure of your wall (concrete, brick, plasterboard) for wall mounting. The anti-tip bracket is usually screwed onto the top panel and anchored securely into the wall.

Common Pitfalls and Professional Tips

• Doors rubbing or hanging crooked: The concealed cup hinge can be adjusted in three dimensions. The front screw on the hinge arm adjusts the door to the left or right (gap alignment). The rear screw regulates the depth (distance to the carcass), and the mounting plate allows height adjustment.
• Drawers jamming: If your wardrobe features internal or external drawers, check the runners. A full-extension runner must be fitted exactly parallel. Measure the distance of the tracks to the front edge on both sides with millimetre precision.
• Solid wood moves: When assembling a solid wood wardrobe, leave at least 2 cm to 3 cm of clearance between the wardrobe and the wall to allow air circulation and prevent moisture build-up.

FAQ — Frequently Asked Questions about Wardrobe Assembly

How many people are needed for assembly? For small models, one person may suffice, but at the very latest when lifting the carcass upright and hanging large doors, two people are strictly necessary to avoid damage to materials and personal injury.

How do I level a wardrobe on an uneven floor? Use adjustable plinth feet if available. Alternatively, slide flat wooden or plastic packers under the load-bearing side panels until the spirit level indicates precise horizontal and vertical alignment. This is essential for the doors to close smoothly later.

Why do the doors have uneven gaps? An uneven gap is almost always caused by a carcass that is not plumb. First check the alignment of the entire unit with the spirit level. Once the carcass is level and plumb, readjust the gaps using the adjustment screws on the concealed cup hinge.

Can I also assemble a sliding door wardrobe lying flat? The carcass is assembled lying down, but the tracks and doors are only fitted once the wardrobe stands upright in its final position. Heavy doors would exert too much leverage on the tracks when lifting the unit.
