ᐅ How do I install Ikea Pax wardrobes in rooms with sloped ceilings?

Honestly, I find the whole idea of installing Pax wardrobes in sloped ceilings somewhat makeshift. Sure, IKEA offers great systems, but their modularity is mainly designed for standard rooms. Why not opt for custom-made furniture tailored to the slope right from the start?

I mean, anyone who doesn’t want to be slowed down by limitations and modifications quickly falls for so-called quick fixes that end up costing a lot in time, effort with grinders, paint, and nerves – only to realize later that compromises had to be made.

I would argue that anyone who values maximum space utilization in sloped ceilings should consider CNC-milled lightweight construction elements. The whole "cutting down and forcing" Pax approach, to me, is a makeshift solution for those who don’t want to invest much craftsmanship time in the project.

Of course, custom solutions are always ideal, but they tend to be significantly more expensive and time-consuming.

For many, PAX offers a good balance of flexibility, cost, and availability. With careful planning, it is definitely possible to achieve a neat fit using PAX systems. Here are some helpful tips:

- Make use of the adjustable heights of the PAX systems, which come in three standard heights.
- Experiment with the 3D planning tools that IKEA provides to virtually map the slope and simulate adjustments.
- Use different types of doors—for example, sliding doors instead of hinged doors when the slope interferes with the door opening.

I understand the argument of a "makeshift solution," but there are definitely cases where good results can be achieved with minimal effort. Compromises are often necessary, but they are not always a reason to reject the system outright.

I’m interested to know whether the roof slope in your project runs continuously along one wall or if there are corners with different angles.

This is crucial for planning. With a uniform slope, simple adjustments using trims and custom-cut doors are usually sufficient, but with more complex angles, adjustable tracks for cabinet doors might be necessary to compensate for gaps.

It’s also important whether the slope inclines inward or outward—that is, whether you leave a lot of space behind the cabinet or not. In tight spaces, it can sometimes be helpful to build the PAX frames without a back panel and use the slope itself as the back to accommodate height differences.

It sounds more complicated than it is, but initial plans with precise measurements are extremely helpful for advice.

Thank you for asking, that is really important. The roof slope extends almost continuously and evenly along one wall, without any angle changes – so a clean 45-degree surface. The length of the slope is about 4.5 meters (15 feet).

The room depth is 3.5 meters (11.5 feet), and the opposite wall is vertical with a height of about 2.5 meters (8 feet). I plan to build the cabinet along the sloped wall; the floor is level, so there are no steps or height differences.

I could theoretically leave out the cabinet’s back panel if it remains stable enough. Creating sections with different depths is also an option, which I like.

How can I scale or modularly configure the PAX frames to better fit common roof slope dimensions?

The PAX system can be excellently configured in modules of 50, 75, and 100 cm (20, 30, and 40 inches) in width. For sloped ceilings, I recommend using smaller modules (50 or 75 cm), which can be individually adjusted in depth and height.

My approach:

- Plan the modules so that the deepest ones (58 cm / 23 inches) are placed in the tallest areas.
- Position shallower modules (35 cm / 14 inches) or even lowboard-style units in the sloped sections.
- Module height can be precisely adjusted by removing the top crossbars or trimming the side panels to the millimeter.
- Use panels above the cabinets to visually frame the sloped ceiling and close small gaps.

Also, make sure to carefully mark and cut the doors with a table saw; safety and precision are important here to achieve clean finishes.

I recommend creating a sketch or even a 3D model of the room before purchasing, noting the exact measurements of the slope step by step. This will help you select the optimal PAX modules.
