ᐅ How do I properly install Ikea Pax wardrobes on a sloped ceiling?

First, saw the side panels to fit the slope. Attach the back wall in several sections. Doors can be shortened or left open at the top if needed. Always secure screws into the wall.

Thanks for the quick responses so far!

@zarlu: I understand the point about custom-made furniture, but unfortunately the budget is tight and Pax otherwise offers enough storage space. Custom furniture obviously looks better aesthetically, but functionality comes first here.

@sarlo, @letar: Your advice regarding the backs and wall mountings is very helpful. Do you think it’s possible to use regular chipboard panels as individual elements for the back, as long as they are securely fixed?

How does this affect the stability compared to the original Pax back panel?

Thanks also for the tip about the bevel gauge; I’ll make sure to get one.

Are there any other tips on what to particularly watch out for when attaching to the wall, especially if the wall isn’t perfectly vertical but slightly angled?

Yes, that works well. Make sure the thickness is sufficient (at least 8 mm (0.3 inches)) and that fastening is straightforward (screws or brackets). In terms of stability, it’s comparable because the back wall in Pax mainly serves to stiffen the structure.

In that case, it is important to choose anchors and screws that reach the load-bearing structure. For angled wall surfaces, adjustable brackets or special mounting brackets can help to properly align the cabinet.

When in doubt, it’s better to use longer screws and adjust the distance to the cabinet with washers.

It is interesting that almost everyone here assumes that the Pax wardrobe should be used as a standard module despite the sloped ceiling.

Why not opt for a custom-made solution instead? Ikea’s assembly instructions are designed for right angles – it simply can’t be optimal.

This is a key point. Trying to adapt a system intended for regular rooms to fit a sloped ceiling inevitably leads to compromises.

Using particleboard as a back panel replaces the original, but it lacks the original connection system and precise fit – which can quickly affect the overall appearance and stability.

Therefore, it is important to carefully weigh whether to prioritize flexibility at any cost or to lean toward a tailor-made solution that is more sustainable and structurally secure, even if it requires more effort.

Good point, theo63. I agree to some extent but want to approach this with a certain pragmatism for now. My main question regarding installation on a sloped ceiling is whether you have any specific tips or experience on how to best adapt the original Pax components (straight parts: side panels, back panel, doors) to the sloped roof shape without compromising stability.

How do you properly redirect the back panel when it is installed in sections? Are longer screws in the corners sufficient, or is it better to use additional brackets and braces?

Also, does anyone have recommendations on how to shorten or modify the doors so that they still function properly?

The back panel sections must lie flush and be secured at the joints with brackets or metal connectors. This creates a stable surface unit that ties the side walls together.

Longer screws alone are rarely enough. Use special mounting brackets at critical points to distribute the loads.

Doors can be shortened using a router or jigsaw. Be sure to also adjust or reposition the hinges and guide rails accordingly. Alternatively, sliding doors offer more flexibility for height adjustments.
