Transforming a standard wardrobe into a seamless built-in can revolutionise small-space storage. Many homeowners are discovering that modular systems offer surprising capacity—sometimes rivalling traditional walk-in closets. Take, for example, a clever setup using three 39″ and one 19″ unit, achieving an impressive 136″ of linear storage in a compact bedroom.
This approach isn’t just about saving space; it’s about living large while downsizing. By customising off-the-shelf units, you can match—or even surpass—the functionality of pricier built-ins. One family found their new arrangement provided the same storage as their previous 48 sq ft walk-in, proving that smart design trumps square footage.
The secret lies in strategic adjustments: precise trimming, seamless gap-filling, and a fresh coat of paint. With these tweaks, a basic wardrobe blends effortlessly into your room’s architecture. Best of all? This solution costs a fraction of custom cabinetry while offering equal versatility.
Key Takeaways

Introduction to the IKEA Built-In Wardrobe Hack
Many UK homeowners struggle with cluttered bedrooms due to inefficient storage solutions. Freestanding dressers and bulky cabinets often eat into precious space without offering enough room for clothes, shoes, or accessories. The result? A constant battle against mess and frustration.
Enter the Pax wardrobe system—a flexible middle ground between temporary furniture and expensive renovations. Unlike traditional setups, these modular units adapt to your room’s dimensions, creating floor-to-ceiling storage without demolition work. One family, Young House Love, used Pax to replicate their 48 sq ft walk-in closet along a single bedroom wall—all while downsizing their home.
What makes this approach stand out? Time efficiency. A project like this can be completed over four afternoons, turning chaos into order quickly. Plus, with customisable finishes and trims, the units blend seamlessly with your existing décor, looking like they’ve always belonged.

For those tired of makeshift solutions, the Pax system offers a smarter way to organise. It’s not just about storing more—it’s about living better in smaller spaces.
Why Choose an IKEA Pax Wardrobe for Your Built-In Project
Homeowners seeking smart storage often face a dilemma: custom solutions break the bank, while freestanding units waste space. The Pax system bridges this gap, offering tailored functionality without the bespoke price tag.
Affordability vs. Custom Solutions
Laura Gummerman’s renovation revealed stark savings: her Pax setup cost 75% less than traditional cabinetry. Similarly, Young House Love’s project totalled £1,200–£1,800—compared to £5,000+ for custom builds.
“We replicated our walk-in closet’s capacity along one wall, saving thousands and gaining flexibility.”
Key advantages:
- 70% cheaper than bespoke joinery
- Mix 13″ and 23″ depths in one installation
- 93″ height fits standard UK ceilings (2.4m)
Flexibility in Design and Configuration
The modular system adapts to evolving needs. Over 100 configurations are possible with IKEA’s online planner—ideal for awkward alcoves or sloping ceilings.
Proven durability adds value: real-world cases show Pax units lasting 15+ years with minimal wear. It’s a practical way to maximise space without compromising on style or longevity.
Tools and Materials You’ll Need
The right tools transform a basic storage unit into a polished, custom-looking feature. Whether you’re a seasoned DIYer or a first-timer, having everything on hand streamlines the process. Here’s what to gather before starting.
Essential Tools: Miter Saw, Nail Gun, and More
Precision is key for seamless results. A miter saw (£150+) ensures clean cuts for trim and moulding. Pair it with a nail gun (£80–£120) to secure pieces firmly—no shaky brackets here.
Other must-haves:
- Caulk gun (£10) for gap-filling
- Level to keep everything aligned
- Respirator (for Zinsser BIN shellac primer)
Materials: Trim, Paint, and Filler Boards
Trim bridges gaps between units and walls. Use 1×3″ backer boards for support and quarter-round moulding for refined edges. Painter’s caulk hides seams beautifully.
For paint, Laura Gummerman matched her walls with Behr’s *Melting Icicles*, while Young House Love opted for Sherwin-Williams *Pure White*. Water-based eggshell works best on laminate surfaces.
Pro tip: Repurpose Komplement shelves as filler boards to save costs. Sand wood filler smoothly before painting for a flawless finish.
Planning Your IKEA Built-In Wardrobe Layout
A well-planned storage solution starts with precise measurements and smart sizing. Whether you’re working with an alcove or a full wall, getting the dimensions right ensures a seamless fit. Avoid guesswork—use a laser level for multi-unit alignment and account for skirting boards or cornices.
Measuring Your Space Accurately
Begin by measuring the wall space where the units will sit. Note these critical gaps:
- 3mm clearance for doors to open smoothly
- 20mm expansion gaps near plasterboard walls
For linear storage, subtract 15mm per joint. Example: Three 60cm units provide 178.5cm of storage (180cm minus 1.5cm).
Choosing the Right Unit Sizes
Mix depths (13cm or 23cm) to suit your needs. Bifold doors require at least 60cm clearance on either side. Here’s a quick guide to weight limits:
| Unit Depth | Max Shelf Weight |
|---|---|
| 38cm | 20kg |
| 58cm | 30kg |
Pro tip: Use filler boards to bridge uneven walls. This simple way to align units creates a custom look without costly adjustments.
Step 1: Assembling and Securing Your IKEA Pax Wardrobe
Proper assembly transforms flat-pack furniture into a long-lasting storage solution. Begin by laying out all parts in a clear workspace—this avoids confusion mid-process. Follow the manufacturer’s instructions meticulously, but note a few key adjustments for built-in projects.
Follow the Assembly Instructions with Care
Skip the plinth if you’re building on a raised platform, as Laura Gummerman did. Her 2×4 timber base, secured with 3″ construction screws, added stability and levelled uneven floors. Assemble units upright to prevent warping—lying them down can distort the frame.
For larger configurations, reinforce the box structure with extra brackets. The modular system allows for mixing depths, but remember: 58cm-deep units need floor support every 80cm to handle heavier loads.
Anchor Firmly to the Wall
Safety is non-negotiable. Use Fischer DuoPower 8x40mm wall plugs for solid masonry, or toggle bolts for plasterboard. Young House Love’s anti-tip brackets ensured their closet stayed put, even in a busy household.
Here’s a quick guide to weight limits:
| Unit Depth | Max Shelf Weight |
|---|---|
| 38cm | 20kg |
| 58cm | 30kg |
Pro tip: Leave 3mm clearance on either side for sliding closet doors to glide smoothly. A level and shims help adjust for wonky walls.
Step 2: Creating a Built-In Look with Trim and Moulding
The difference between off-the-shelf and built-in lies in the finishing touches. Strategic use of trim bridges gaps, while moulding adds architectural harmony. These details make modular units appear as permanent fixtures.
Adding Backer Pieces for Support
Young House Love’s 1×3″ backer board technique creates a stable foundation. Fix 19mm plywood strips with 50mm nails for firm support against walls. This method works particularly well for uneven surfaces.
For wavy walls, Laura’s scribing method ensures perfect alignment:
- Use a compass to trace wall contours onto the backer board
- Cut along the marked line with a jigsaw
- Test fit before final installation
Installing Crown Moulding and Baseboards
Crown moulding completes the built-in illusion by hiding ceiling gaps. Standard UK cornices typically require 52° angle cuts. For minor imperfections, 6mm quarter-round trim provides a clean solution.
Consider these material options:
- Budget-friendly: Primed MDF at £12/m
- Premium choice: Hardwood at £35/m
Secure moulding with finish nails for discreet fastening. A bead of painter’s caulk along the edges ensures seamless integration with your walls. The result? A polished look that appears custom-designed for your space.
Step 3: Filling Gaps and Seams for a Seamless Finish
What separates amateur work from expert craftsmanship? Seamless joints. Even the best-assembled units need careful gap treatment to achieve that custom look. This stage transforms visible seams into invisible transitions.
Using Caulk and Wood Filler
Laura Gummerman’s project demonstrated how strategic filling elevates results. For cracks under 5mm, she used UniBond Anti-Crack Caulk—its flexible formula prevents future cracking. Larger gaps require the “V” groove method:
- Cut a shallow groove along the seam
- Press in Everbuild One Strike filler with a putty knife
- Feather edges before drying
Avoid silicone-based products—they repel paint and create headaches later. For screw holes, wood filler dries faster (30 mins vs 4 hours) and sands smoothly.
Sanding for a Smooth Surface
Young House Love achieved their Sherwin-Williams Pure White finish through meticulous sanding. Their protocol:
- Start with 120-grit paper for rough shaping
- Progress to 220-grit for polishing
- Vacuum dust between coats
This creates the perfect base for paint adhesion. Remember: a flawless finish hides all imperfections, making your work look professionally installed.
Step 4: Painting Your IKEA Wardrobe to Match Your Room
The final transformation from flat-pack to custom storage happens with the perfect coat of paint. This stage blends your new storage seamlessly into the room’s architecture. Laura Gummerman’s Behr Melting Icicles proved how colour matching creates visual harmony.
Choosing the Right Paint for Laminate Surfaces
Laminate requires special preparation for paint adhesion. Zinsser BIN shellac-based primer creates the ideal base, bonding to slick surfaces where water-based primers fail. Young House Love’s project showed this preparation lasts years without peeling.
Consider these professional choices:
- Water-based eggshell for easy cleaning (2-hour recoats)
- Oil-based alternatives for durability (16-hour drying)
- NCS colour codes for perfect IKEA white matches
Tips for a Professional-Looking Finish
Application method affects results dramatically. An HVLP spray system achieves 95% smoothness compared to 80% with brushes. For touch-ups, automotive pens blend scratches invisibly.
“Our spray gun technique eliminated brush marks completely, giving a factory-finished look.”
Maintain your finish with microfibre dusting and occasional wax polish. This preserves the custom look for years, proving smart preparation pays off long-term.
Customising Your Built-In Wardrobe Further
The true magic happens when personal details transform practical storage into a design statement. While the basic structure provides functionality, thoughtful additions create that custom look distinguishing professional installations from DIY projects.
Crafting Bespoke Drawer Fronts
Replace standard panels with 18mm MDF fronts for a seamless appearance. Maintain a precise 2mm reveal between drawers using spacer blocks during installation. This technique achieves that tailored look found in high-end furniture.
Consider these hardware options:
- 96mm brass pulls (Emtek’s satin finish works beautifully)
- Leather-wrapped handles for tactile luxury
- Flush-mounted touch catches for minimalist designs
Illuminating Your Storage Space
Strategic lighting transforms dark corners into display-worthy areas. Compare these popular solutions:
| Option | Cost | Installation |
|---|---|---|
| 12V LED strips | £35/m | Requires wiring |
| Battery puck lights | £12 each | Self-adhesive |
For back panels, grasscloth wallpaper adds texture while disguising wiring. As one designer noted:
“Routed puck lights behind frosted acrylic create museum-quality display lighting without visible fixtures.”
Velvet-lined drawers and leather-wrapped rods complete the luxe look. These custom touches prove that modular systems can rival bespoke designs when attention meets creativity.
Conclusion: Enjoy Your Custom Built-In Wardrobe
Your new storage solution proves that downsizing doesn’t mean sacrificing space. Like Young House Love discovered, smart design can match—or even exceed—traditional walk-in capacity. The result? A closet that looks like it was always part of your house.
Keep your system in top shape with simple care. Lubricate hinges yearly and check drawer alignment. Use dividers to maximise space efficiently. These small steps maintain that polished look for years.
Beyond daily use, this project adds value. Built-ins can boost property appeal by 3-5%. Future changes are easy too—reconfigure shelves or doors as needs evolve.
Most importantly, you’ve achieved professional results at a fraction of bespoke costs. Now enjoy a clutter-free home with storage that works as hard as you do.
