ᐅ How can I securely install IKEA Metod cabinets on uneven walls?

Hello everyone,

I am facing the challenge of securely mounting IKEA Metod kitchen cabinets on a noticeably uneven wall. The wall is neither fully flat nor consistently straight, which makes attaching the cabinets using the standard brackets difficult. It seems that the usual methods (directly screwing into the wall or using the supplied wall hangers) will hardly work or only work to a limited extent because the cabinets might not hang flush or could visibly wobble due to irregular fastening.

I have considered ways to compensate for the unevenness—such as using spacer blocks or special brackets—but I am unsure which approach is recommended for Metod cabinets and how to ensure both stability and a clean appearance.

Does anyone have experience, practical tips, or professional advice on this, especially when the wall is significantly uneven and not just slightly irregular? Are there special anchors, fasteners, or techniques I should be aware of?

Thanks in advance for your help!

I would recommend first marking the largest uneven spots with a spirit level and then placing appropriate shims or spacer blocks behind the cabinet brackets. This will create a flat mounting surface. Then secure everything to the wall using suitable anchors and screws. It is important that everything is firmly fixed; otherwise, the cabinet will wobble.

Interesting approach, but just for discussion: wouldn’t it be better to first level the wall mechanically, that is, to even out the irregularities with plaster or filler? Sure, it takes time, but it can provide much greater long-term stability.

Using shims can hide unevenness, but it increases the risk that pressure could build up on the cabinets due to different material stresses. Does anyone here have experience with lasting results without preparing the wall?

I would like to explain in detail the approach for dealing with uneven walls, especially when installing IKEA Metod cabinets.

First, measuring the wall accurately is essential: use a long spirit level or, even better, a straight edge, and don’t just check at isolated points but measure across the entire surface for any irregularities. Then, you can use leveling materials such as wooden shims or plastic wedges to compensate for the gaps between the brackets and the wall. It is advisable to mount the brackets so that they sit flush with the front of the cabinets, as otherwise, visual and mechanical problems may arise.

Second, the wall plugs and screws for mounting must be suitable for the wall material. For drywall, special metal or cavity anchors are necessary; for concrete or brick, traditional expansion plugs or chemical anchors are options. Using strong anchors combined with evenly distributing the load over multiple brackets greatly increases stability.

Third, the cabinets themselves must be securely connected. Beyond IKEA’s provided connectors, it is recommended to reinforce the connection between cabinets with angle brackets or connecting clips. This way, the load is spread over several points, and a single wall mounting does not have to bear the entire weight.

Finally, if the gap to the wall becomes too large, wide, thin spacer plates can be used and adjusted precisely to keep the back of the cabinet aligned.

I would be interested in more details: What type of wall material is it exactly? How large are the irregularities quantitatively?

Thanks kulau, good questions. The wall is made of fairly old brick, covered only with a thin layer of textured plaster – not a smooth finish, but rather rough and uneven. The irregularities measure up to 15mm (0.6 inches) both vertically and horizontally. These aren’t just small dents, but actual waves and slight bulges along the wall surface.

I have also seen the connecting brackets between cabinets, which definitely look more stable. My concern is more about the mounting itself – that despite compensating for the unevenness, the cabinet might still wobble or that the screws could loosen over time because of the wall’s texture.

15 mm (0.6 inches) is quite significant. Honestly, I wonder if you can really call it a secure fastening on such a wall without proper preparation beforehand. I often see people just improvising, and in the end, the entire construction is either unstable or needs constant readjustment – to me, that’s not a real solution.

My hypothesis: either you make the wall fairly flat (using filler or by installing drywall panels) or you skip that and build freestanding cabinet units with feet instead of wall mounting – this is often more stable and causes less hassle.

In my opinion, anyone who only uses shims here is just treating the symptoms, not the root cause.
