Built in wardrobes, sized to a wall that isn't square

Summary: Built in wardrobes solve the gap between square furniture and rooms that are not square. Measure width, height, diagonals, floor slope, ceiling details, and door swing before comparing fitted wardrobes, PAX hacks, or cut-to-size panels.

The wall in our bedroom is 2.64 m at the floor and about 2.615 m at picture-rail height. Nothing is straight in a 1908 building, and the skirting is original, which means it's also not straight. I measured it three times because I didn't believe the first two readings.

That mismatch is the whole reason built in wardrobes exist. A free-standing wardrobe is built for an idealised wall: 90-degree corners, flat plaster, level floor. Real walls don't do that. So you either lose 8 to 12 cm of usable depth to a chunky off-the-shelf carcass, or you commit to fitted ones that hug the actual room.

What "built in" actually changes

A built in wardrobe takes the room as the back wall. No carcass back. No 18 mm panel and a 1 cm air gap behind it. You gain that depth as hanging space, which on a 60 cm carcass is the difference between a coat fitting on a hanger and a coat squashing against the door.

The other thing it changes is the top. Most freestanding units stop at 2 or 2.2 m and leave a dust trap above. A built in runs to the ceiling, which on our 2.615 m wall is 41.5 cm of extra storage that would otherwise live in cardboard boxes labelled "ski stuff".

The trade-off is honest. Built in means you can't take it with you. If you're renting and your landlord is a normal human, that's usually fine, but it's worth flagging.

What people actually pay

I looked at quotes for our wall (2.64 m wide, 2.615 m high, 60 cm deep) earlier this year. Rough numbers, all in euros, all for a two-bay setup with hanging on one side and shelves plus drawers on the other:

• Local carpenter, fully bespoke: 4,800 to 6,400. Six to ten weeks.
• Sharps-style branded fitted wardrobe company: 5,200 to 7,800. Their cheap range starts lower in marketing and ends higher in real life.
• IKEA Pax with filler panels and a scribed cornice: 1,400 to 2,100 in materials, plus a weekend or two of cursing.
• Pre-cut panels delivered, cam-lock assembly, no saw at home: about 2,200 to 2,900.

The middle option is where most fitted-wardrobe advertising lives. It's a real service and the people doing it are usually skilled. Most of the cost is install labour, not materials.

UK readers will recognise "fitted wardrobes" as the same thing under a different name. American readers usually call it a built-in closet. Same idea, different door.

Measuring without lying to yourself

Three rules I wish someone had told me before the first attempt.

First, measure both diagonals of the alcove, not just the width. If they don't match by more than 5 to 8 mm, the wall isn't parallel and you'll need scribed filler panels to hide the gap. This is normal in any building older than about 1980. Mine were off by 14 mm, which is a lot.

Second, take the floor level reading at four points, not one. Old floors slope. In our flat the bedroom drops 11 mm from the window wall to the door. A wardrobe built to the high side will sit on packers at the low side. Fine, as long as you've planned for it.

Third, measure the ceiling height in at least three places along the wall. Plaster sags. Joists move. The ceiling above our wardrobe is 2,615 at one end and a few millimetres higher in the middle. We sized to the lowest reading and let a 6 mm shadow gap run along the top.

If a built in wardrobe company shows up to quote and only takes one width, one height, one depth, that's a tell. They're going to absorb the slop with oversized scribes and a lot of caulk.

The bit nobody mentions: the ceiling

Most fitted wardrobe horror stories I've read on Reddit boil down to the ceiling. Cornice, picture rail, ducting, recessed lights. The wardrobe is sized to fit the wall but nobody noticed the cornice eats 3.5 cm at the top, or the loft hatch is right above where the doors will swing.

Walk along the wall with your phone before you commit to anything. Photo every 30 cm or so, including up. Note the cornice profile. Note where the ceiling rose sits. If there's a recessed downlight within 20 cm of the wall, that's a planning constraint, not a detail.

Sliding versus hinged doors

Sliding doors save 60 cm of swing room, which in a small bedroom is most of the floor between the bed and the wardrobe. They cost more, eat about 8 cm of internal depth for the track, and you can only ever see half the wardrobe at a time.

Hinged doors are cheaper, give you full access, and need clear floor space the width of the door. For a 60 cm door that's a lot in a 3 by 3.4 m room.

Rule of thumb I've landed on: if your bed is more than 70 cm clear of the wardrobe wall, hinged. If it's tighter, sliding. Mirrored sliders are a separate question and mostly an aesthetic one. Some people love them. I find them dazzling first thing in the morning, but that might just be me.

So what do you actually do

If your wall is straightforward (post-1990 build, square corners, flat ceiling), an IKEA Pax with filler panels probably gets you 80 percent of the way for a quarter of the price of bespoke. If your wall has any of the things mentioned above (sloping ceiling, alcove, picture rail, wonky floor), the maths shifts. The labour cost of making a freestanding solution fit usually exceeds the labour cost of just having it cut to size in the first place.

That second case (the wonky old wall, the awkward alcove, the 41.5 cm of unclaimed ceiling space) is the one knuslabs.com was built for: send the room a photo and the measurements, get back a panel layout that fits the actual wall, and build it without a saw.
