ᐅ How do I install Ikea Metod wall cabinets on uneven walls?

Hello everyone, I am currently facing the challenge of installing Ikea Metod wall cabinets on a wall that is unfortunately not completely flat. More precisely, I can feel slight unevenness and small protrusions on one side, which makes precise alignment of the cabinets difficult. My question is: What techniques and installation methods would you recommend to ensure the Metod wall cabinets hang securely and straight, even if the wall is uneven?

I would be interested in tips regarding:
- Methods to compensate for irregularities in the wall itself or at the mounting points
- Use of the same or different fasteners and hardware
- Adjustments to the cabinets, such as using shims or spacers

I want to avoid the cabinets hanging crooked or being poorly aligned afterwards. Thanks in advance for your experience and advice!

Hey nuloman, great that you’re asking such detailed questions! 😊 I had a similar issue with Metod cabinets at my home. The first important step is to measure any unevenness very precisely – take your time using a spirit level and measuring tape!

My top tip: definitely use washers or narrow wooden shims as spacers behind the mounting points. This way, you can easily compensate for small irregularities and align the cabinets straight against the wall.

And very important: don’t just use standard wall plugs; choose ones with longer and stronger holding power, especially if the wall surface isn’t perfectly smooth. This is really crucial for safety!

You’ve got this! Just proceed step by step and check everything again with the spirit level at the end!

That may be true, but honestly – why bother trying to even out the irregularities? Ikea actually has a rather straightforward approach with Metod: shouldn’t we first question whether the entire system is designed for such uneven walls at all?

In my opinion, the system is meant for smooth walls, and if you rely too much on workarounds, you risk everything sitting under tension, which can lead to sagging over time or even damage.

In my view, it’s better to properly level the wall or at least install a flat mounting strip afterward, rather than fiddling with wooden blocks or spacers. This will save a lot of trouble in the long run.

Good morning! I would like to add a few technical details to the discussion, as installing Ikea Metod wall cabinets on uneven walls is often a challenge.

First, regarding the wall issue: Deviations of more than 5 mm per meter (0.2 inches per 3.3 feet) can complicate the installation. The process should be done in several steps:

- First, thoroughly check the wall. A long straightedge can be used to measure the irregularities accurately.
- If the wall is significantly uneven, a mounting rail made of wood or metal can be used. The mounting rail is fixed to the wall with sufficiently strong anchors and creates a level surface for the cabinets to rest on.
- The wall cabinets are then attached directly to the mounting rail, which is positioned behind the cabinet back panel, allowing the cabinets to be leveled with a spirit level.
- Alternatively, spacers (usually plastic or wood) can be placed behind the mounting screws to compensate for smaller unevenness.

It is important to choose the correct anchors depending on the wall material (e.g., concrete, drywall/plasterboard, brick) and select suitable anchors and screws accordingly.

Additionally, it is advisable to align the cabinets before final installation and before attaching the front doors, as this makes any necessary adjustments easier.

Could you please indicate approximately how uneven your wall is and what material it is made of? That would help provide better advice.

Could you maybe also mention approximately how large the surface irregularities are and what material your wall consists of?

Thanks, lorena, good question. My wall is an older brick masonry, plastered, but partly uneven – about 7 to 10 mm (0.3 to 0.4 inches) deviation over one meter (3.3 feet). I would describe the unevenness as wavy, and there are also slight plaster offsets.

I do tend to follow your suggestion to use a mounting rail, since I want to avoid dealing with crooked cabinets later on. However, it is still unclear how stable the wall really is for screws in its aged condition.

Are there any special considerations for anchors or screws that are specifically recommended for these kinds of older brick walls?

Also, I would be interested to know if anyone has experience with combining a mounting rail plus spacers for fine adjustments.

In your situation with an uneven, older brick wall, I recommend the following approach:

- Use a solid wood mounting batten, for example spruce, at least 40 mm (1.6 inches) wide and 18 mm (0.7 inches) thick.
- Drill a sufficient number of appropriate anchors for fastening the batten, such as hammer-in anchors or chemical anchors, as these provide better hold in porous bricks.
- The spacing between anchors should not exceed 50 cm (20 inches).
- Install the batten so that it is perfectly level using a spirit level or laser level.
- To compensate for minor unevenness, thin wooden shims or plastic spacers can be placed between the cabinet and the batten during cabinet installation.
- When mounting the cabinets to the batten, be sure to observe the load limits and use screws according to the cabinet manufacturer’s instructions.

The combination of a mounting batten plus spacers is well-proven in practice and allows for precisely adjusted and secure hanging, especially on older walls with irregular surfaces.
