How to Build an IKEA PAX Wardrobe Without Damaging the Wall

I get called out for IKEA PAX wardrobe builds about once a month, and it’s usually because the wall anchor brackets won’t reach a stud. PAX is engineered for European houses where studs sit at 625 mm centres in 16 mm Gyprock. Aussie homes have studs at 450 or 600 mm centres in 10 mm plasterboard, and the PAX bracket holes don’t always line up. The instructions don’t mention this.

The good news: there’s a workaround that doesn’t involve butchering the cabinet or living with a wardrobe that’s only secured by gravity and good intentions. PAX is a 1,200 mm wide cabinet with 235 mm of vertical bracket adjustment — there’s almost always a stud you can hit if you know where to look. And if there genuinely isn’t, the right toggle anchor for 10 mm plasterboard handles 60+ kg, which beats the official IKEA lateral-load rating anyway.

The Aussie-specific bit: 16 mm European drywall (German Knauf, Swedish Norgips) is twice as strong as Aussie 10 mm Gyprock or USG. The PAX wall anchor relies partly on plasterboard pull-out resistance. With our thinner board, you must hit a stud or use a proper toggle bolt — Hangman, Toggler, or Snaptoggle, all stocked at Bunnings or Total Tools — not the foam plastic “wall plug” supplied in the IKEA bag.

What you’ll need

An IKEA PAX cabinet (any size, instructions assumed)
A stud finder (Bosch Truvo or GMS 120 — $80–150) — magnet finders don’t work on metal-stud walls
Snaptoggle 10 mm plasterboard anchors (pack of 4, $18 at Bunnings) — backup if no stud reachable
30 mm or 40 mm wood screws #8 (for stud fixings) — better than the supplied IKEA screws
A drill with 6 mm and 12 mm bits
A 1.2 m spirit level
A pencil
An Allen key set (the IKEA one is fine but a real one with a handle is faster)
2 hours of patience and a podcast

Step 1: Build the cabinet flat on the floor

Don’t try to build PAX vertical — it’s 2,360 mm tall and you’ll snap a side panel. Lay it flat. Follow the IKEA instructions for the carcass build — top, bottom, sides, back panel hammered into the rebate. Don’t fit the doors yet, doors go on last after the cabinet is anchored.

The hardboard back panel is the bit that holds PAX square. If you skip the back-panel pin nails and try to stand the cabinet up first, the whole carcass will rack and the doors won’t sit straight. Pin every back-panel nail.

Step 2: Mark the stud line on the wall before you stand the cabinet

This is the bit IKEA doesn’t tell you. Before you lift the cabinet upright, run the stud finder along the wall at 2,000 mm height (where the PAX wall bracket will land). Mark every stud you find with pencil — usually 3–4 across the 1,200 mm cabinet width.

For metal-stud walls (most modern apartments and some 2000s+ homes), use an electronic stud finder, not a magnet finder. Bosch Truvo handles both timber and metal studs.

Step 3: Stand the cabinet up — two people

PAX flatpack-built is around 60 kg. Two people, one each end, walk it up. Position 50 mm from the wall — leave room to fit the wall bracket behind.

Step 4: Locate the supplied wall bracket

PAX ships with a metal wall anchor bracket — an L-shaped piece that screws to the inside top of the cabinet (on a track that lets it slide left-right) and to the wall via a single screw point. Find it in the hardware bag.

The cabinet-side of the bracket attaches first. Slide it into the channel on the inside top of the cabinet, position roughly above where you marked your stud, snug it up.

Step 5: Mark the wall through the bracket hole

With the cabinet positioned where you want it (use the spirit level to confirm vertical), reach inside and mark the wall through the bracket hole with a sharp pencil. Pull the cabinet 200 mm forward to give yourself room to drill.

PAX bracket: hit a stud if possible, Snaptoggle if not — never the IKEA wall plug

Step 6: Decide — stud hit or toggle?

Look at your pencil mark vs the stud lines you marked in Step 2. Is your pencil mark within 30 mm of a stud? If yes, slide the bracket along its cabinet-side channel until it lines up exactly with the stud, re-mark, drill and screw direct.

If the bracket can’t reach a stud no matter how you slide it, use a Snaptoggle. Don’t use the supplied IKEA wall plug — it’s designed for 16 mm European drywall and pulls out of 10 mm Aussie Gyprock under any lateral load.

Step 7: Stud fix — drill 3 mm pilot, drive 40 mm wood screw

Pilot hole 3 mm into the stud. Drive a 40 mm #8 wood screw through the bracket into the stud. Don’t use the IKEA-supplied screw if you’ve got the choice — the supplied screw is a coarse-thread chipboard screw that binds in timber studs.

Step 8: Toggle fix (if no stud) — 12 mm hole, Snaptoggle

Drill a 12 mm hole through the plasterboard. Push the Snaptoggle through, pull the metal toggle bar tight against the back of the plasterboard, snap off the plastic legs, then drive the toggle’s machine screw through the bracket and into the toggle.

One Snaptoggle holds 73 kg in 10 mm plasterboard — more than enough for the lateral tip-over load PAX exerts. Two Snaptoggles (use both bracket hole positions if your bracket has two) is bulletproof.

Step 9: Push cabinet back, anchor screw home

Slide cabinet back to the wall. Reach inside, snug the anchor screw fully tight. The cabinet should now resist a firm pull-out at the top — give it a tug to confirm.

Step 10: Hang the doors and adjust

Doors hang on the bottom hinge first, then click the top hinge in. PAX hinges are Blum-equivalent with three-way adjustment screws — left/right, up/down, in/out. Use a torch and adjust each door so the gap to the next door is even (3 mm is the IKEA spec).

If your floor isn’t level (most aren’t), level the cabinet first using the adjustable feet underneath, then hang the doors. Hanging doors on an out-of-level cabinet means you’ll be re-adjusting hinges forever.

The Mick rule

Hit a stud if you can, Snaptoggle if you can’t, never trust the IKEA-supplied wall plug on Aussie 10 mm Gyprock. The PAX cabinet itself is fine — it’s the wall fixing that ruins them. A toppled PAX full of clothes is 80+ kg coming down on a person; the lateral anchor isn’t optional and it’s not negotiable. Ten extra minutes to do the anchor right is the difference between a wardrobe that lasts 20 years and a coronial inquest.
