What I learned planning a large mirrored wardrobe for a small bedroom
Summary: A large mirrored wardrobe is mostly a door-weight, depth, and glare problem. The right answer depends on track quality, mirror thickness, usable hanging depth, and whether the wardrobe is cut for the room rather than forced into it.
The bedroom was 2.83 m wall to wall, the bed already ate 1.6 m of it, and the only place a wardrobe could go was a wonky alcove on the north side that measured 1.915 m one way and 1.892 m the other. I wanted mirrors on the doors because the room got no morning sun and I was tired of dressing in a cave. That's how I ended up spending three evenings reading about mirror substrates and float glass tolerances, which is not what I thought planning a large mirrored wardrobe would involve.
If you're in the same place, here's what's actually worth knowing before you buy or commission one.
A "large" mirrored wardrobe is usually 1.8 m or wider
The phrase doesn't have an industry definition, but if you look at what the UK fitted-furniture trade calls "large", it lands somewhere between 1.8 m and 2.4 m wide and around 2.1 to 2.4 m tall. Anything narrower reads as a single tall door. Anything wider usually means three or four panels.
That width matters because of how mirror glass behaves. A single piece of 4 mm float glass mirror at 60 cm wide is fine. At 90 cm wide, on a sliding door, it starts to flex when the door moves. You'll see the reflection wobble. Most decent fitted wardrobe makers put 6 mm mirror on anything wider than around 70 cm, and back it with a safety-grade vinyl film so that if it ever cracks it doesn't shower the carpet.
I didn't know any of this when I started. The first quote I got was for cheap 3 mm mirror on hinged MDF doors. I bought it. Three months in, the mirrors had started to get that orange-peel ripple you sometimes see in budget gym mirrors, because the MDF behind them had moved a fraction with the seasonal humidity. Lesson learned. Pay for the 6 mm or accept the wobble.
Sliding vs hinged is mostly a weight question
For mirrored doors specifically, sliding is usually the better call. The reason is weight.
A 60 cm by 2.2 m hinged door in 18 mm MDF with a 6 mm mirror glued to it weighs roughly 22 kg. The hinges have to take that load every time you open it, plus the swing torque, plus the slam if a kid pulls it shut. Cheap concealed hinges sag inside a year. Good ones (Blum or Hettich, the ones with built-in soft-close) cost about 12 to 18 euros each and you need at least three per door.
Sliding doors put all that weight on the bottom track and a guide at the top, no hinge stress at all. Track quality is the thing to ask about. A polished aluminium top-hung track with sealed bearings will run smoothly for ten years. A pressed-steel bottom track will start to grind in two.
The downside of sliding is depth. You lose roughly 6 cm of usable space inside because the doors have to overlap. So a 60 cm deep wardrobe carcass becomes a usable 54 cm. Hangers need 53 cm minimum to hang a shirt without pressing the cuffs against the back, so you're cutting it close. If your wall depth is fixed at 60 cm, hinged doors give you more breathing room inside.
I went sliding in the end because the alcove was already only 54 cm deep on the narrow side, and a hinged door swinging out would have hit the bed.
Glare is a real problem and nobody warns you about it
A wall of mirror facing a window will throw light into corners you didn't expect. I had a south-facing window 2.4 m from the wardrobe and for about forty minutes every afternoon, between roughly 14:30 and 15:10 in summer, the reflected sun pointed straight at the pillow.
You can solve this in three ways. Angle the wardrobe so the doors aren't perpendicular to the window (rarely possible in a small room). Use bronze-tinted mirror, which knocks back the brightness about 40% and gives a slightly warmer reflection. Or split the door so only some panels are mirrored and others are wood or fabric.
I went with bronze. It cost roughly 18% more than clear mirror per square metre and looks, in person, like the room is permanently in golden hour. I'm fine with it. My partner says it makes them look more tanned than they are.
How a bespoke mirrored wardrobe door is actually built
Most people picture a sheet of mirror stuck to a piece of MDF. The good ones are layered:
- 18 mm carcass-grade MDF or birch ply for the door blank
- A thin EVA foam pad on the back of the mirror so the glass doesn't sit hard against the panel
- 6 mm safety-backed mirror, cut about 5 mm short of the door edge on every side so the silvering can't chip
- An aluminium frame around the mirror, either flush or rebated, which protects the cut edges and stops anyone from running a fingernail along them and slicing themselves
Bespoke mirrored wardrobe doors made this way come in around 70 to 110 euros per square metre at trade prices in the EU, depending on the mirror grade and frame profile. A 60 cm by 2.2 m door is about 1.32 m squared, so 90 to 145 euros per door. For the four-door wardrobe I ended up with, that was roughly 460 euros just in doors.
Sizing for an awkward alcove
The wonky alcove I mentioned, 1.915 m by 1.892 m, is the part most off-the-shelf wardrobes can't handle. A standard fitted system comes in 50 cm, 75 cm or 1 m modules. None of those tile cleanly into 1.915 m.
The fix is to make one panel a non-standard width. In my case, I split the wardrobe as two 75 cm doors and one 41.5 cm filler, with the carcass cut to fit the actual alcove walls (which were 2.3 cm out of square top to bottom, because of course they were). The narrow filler held shoes and the iron. It looked deliberate.
If you're sizing up a wardrobe for an alcove that ends in awkward numbers like 1.892 m, that's the kind of thing knuslabs.com was built to solve.
