ᐅ IKEA BESTA DIY – How to Build a Custom Wall Unit Using Multiple Modules

Hello everyone,

I am currently planning to build a custom wall unit using several IKEA Besta modules. I want to combine different module sizes as flexibly as possible to optimize storage and open spaces for my room. It is important to me that the construction remains stable, especially when connecting different elements such as open shelves, doors, and drawers. I am also interested in recommendations for mounting the unit to the wall, as well as suitable surface treatments and design options so that the wall unit doesn’t look too industrial but blends harmoniously into the living room.

What experiences do you have with DIY assembly of BESTA wall units? How do you plan the combination of modules, which details should I pay special attention to, and do you have any tips regarding tools or a sensible order of assembly? I would really appreciate concrete advice and, if possible, suggestions for practical materials or tricks you have used yourself.

Hello Pugumu,

When connecting different BESTA modules, it is crucial to first accurately measure your wall and the furniture. To ensure your wall unit is stable, I recommend not just placing the modules side by side but securing them with appropriate connectors (e.g., brackets from a hardware store or IKEA-specific fasteners).

For wall mounting, make sure to fix heavy cabinets firmly with sturdy wall anchors and screws, as the weight—especially when drawers and doors are full—can pose a risk to the furniture. Ensure the wall behind has sufficient load-bearing capacity (e.g., not just plain drywall without reinforcement).

For surface finishing, combining the original IKEA finishes with wood fronts or veneers can create a cozier feel. Alternatively, you can add furniture legs to slightly lift the unit off the floor.

Tools: A cordless screwdriver with the right bits, a spirit level, and a protractor will make assembly much easier.

Recommended order: First assemble each module individually, then join them together, and finally attach the entire unit to the wall.

If you need more details about the assembly, feel free to ask.

Hello Pugumu,

I would like to go a bit deeper into the topic, as the modular design of the IKEA BESTA furniture actually requires some planning considerations to create a custom, durable wall unit.

First, about the planning:
- Create a to-scale sketch of your living room including all relevant measurements (room width, height, windows, doors).
- Note the exact dimensions of the individual BESTA modules you want to use (height, width, depth).

Regarding assembly:
- The individual modules are generally stable on their own, but the overall stability and firmness depend heavily on the type of connection and fastening used.
- I recommend using special connectors between the modules, which IKEA or hardware stores offer (e.g., cam locks, brackets) to prevent lateral shifting.

Several important points:
- Wall anchoring is mandatory for larger wall units: use suitable anchors (e.g., metal expansion anchors) depending on your wall type, especially on drywall with special plasterboard anchors.
- Consider reinforcing the back panels as needed, since the thin hardboard panels are not necessarily designed for high loads.
- When combining modules with doors and drawers, make sure the doors can open smoothly without obstruction after installation.

Design:
- The original BESTA colors are usually white or black-brown. For a more personalized look, you can use painted or foil-coated fronts.
- A very effective DIY solution is to install LED strips inside or behind the units to add accent lighting.

Do you already have a concrete plan or sketch? Which modules are you considering? That way, I could tailor my response more closely to your situation.

Hello Pugumu,

You raised some very good points, so I’d like to add a few tips, especially regarding the DIY aspect and the design of your wall unit.

- Planning: It’s worth not only designing the modules to be flat but also varying their depth. For example, combine open shelves with closed compartments to create visual interest.

- Stability: In my experience, using perforated panels and small steel profiles helps distribute weight more effectively. If you connect more than three modules flush together, it can be useful to cut suitable metal reinforcements at the hardware store.

- Assembly tip: First fully assemble each individual module, then connect them and check for levelness. For wall mounting, in addition to screws, I use a silicone sealant to maintain a slight gap from the wall and reduce the risk of moisture.

- Appearance: If you want a wood finish, it’s best to spray or roll on a thin layer of clear varnish over waxed surfaces for durability.

- Tools: Besides a cordless screwdriver, I also recommend painter’s tape for positioning before drilling.

I’m happy to assist with selecting the right modules if you describe your specific needs (storage, display, etc.) in more detail.

Hey Pugumu!

I’m really impressed with the BESTA wall units you’ve creatively put together—it looks like a lot of fun! 🙂

I think the key is to be bold with combinations: for example, I’ve mixed different heights and widths to make the wall feel dynamic.

I also use a variety of fronts, like flaps, doors, and open shelves, so it doesn’t look too monotonous. And LEDs are fantastic for creating a cozy atmosphere.

It’s also important to measure everything very carefully and build step by step—better to measure twice than to deal with crooked shelves later.

So be confident and get started! You’ll definitely manage, and your wall unit will surely be a real eye-catcher! 🙂
