ᐅ How can KALLAX units be combined without visible gaps?

Good morning everyone,

I am currently facing the challenge of connecting several KALLAX units from IKEA in such a way that no visible gaps appear between them. The goal is to achieve as seamless a look as possible, especially when arranging the units side by side or stacked to create a uniform surface.

I’m interested in what options exist to join these cabinets without visible seams—are there special connectors, assembly techniques, or craftsmanship tips that can make this possible?

I have already seen the standard IKEA connection elements, but these often leave narrow gaps visible. I have also considered offsetting the back panels or adding cover strips, but I’m unsure how effective these methods are.

I would really appreciate practical advice or recommendations, especially from those who have experience with such assemblies. Thanks in advance!

The simplest method is to use a wooden batten as a spacer between the modules, which hides any joints. Alternatively, you can connect the modules with clamps or brackets.

I have achieved better results by connecting the modules at the front edge with a self-made wooden panel. This creates a uniform surface.

Hello Lilotra,

your question is very well formulated and shows that you have already considered the common solutions.

The visible gaps between KALLAX units are often due to slight tolerances in manufacturing as well as the simple plug-in system. To completely eliminate these gaps, there are basically two approaches:

1. Mechanical: A secure connection can be made using additional connecting strips or brackets mounted inside or on the frame. The problem is that the units themselves vary slightly in size, so very precise work is required when assembling and connecting them.

2. Visual: Apply faceplates or a surrounding trim that extends beyond the front edges of the units. Such trim effectively hides small gaps and creates a uniform appearance.

My tip: If you value a seamless look, you should choose a T- or L-shaped connection profile made of wood, cut exactly to size. Then connect the units with these profiles and screw them from the inside. This way, you avoid visible gaps without damaging the structure of the units.

Thank you for the detailed advice! By "surrounding trim," do you mean something like an MDF strip that I would attach to the front of the modules? Wouldn’t that be rather complicated and somewhat compromise the sleek design?

Also, I’m interested to know if anyone has experience with whether attaching the modules using internal brackets is stable enough when the modules are placed several meters (yards) side by side.

The edge gap between KALLAX modules is usually around 2-4 mm (0.08-0.16 inches). This occurs due to slight variations in the dimensions of the individual modules.

That is true; it changes the appearance, but it provides a professional solution if you want a seamless front. Alternatively, you can try connecting the modules internally with so-called flat dowels (wooden dowels) or self-adhesive metal connectors, which are somewhat more stable than simple corner brackets.

It is important to work with a long level to ensure perfect alignment. If you only use corner brackets, slight misalignments can occur with several modules, and stability may suffer, especially when stacking higher.
