Cost to convert a box room into a walk-in wardrobe

Question

We want to turn the small bedroom next to the master into a dressing room with built-in rails and shelving. How much does this kind of fit-out typically cost?

Gareth · Answer

Hi you would be looking about 850 to complete a dressing room

Daniel · Answer

Hi the price depends a lot on the existing condition of the room and the amount of carpentry required but as a guide I would say between £800 to £3500 it’s always worth having a free quotation

Converting a small box room into a walk-in closet in the UK typically costs between £1,500 and £5,000, depending on whether you choose a DIY modular system or a fully bespoke professional installation.

Below is a breakdown of the typical costs for a standard 2026 conversion:

1. Project Tiers

• Budget (DIY): £800 – £2,000
Using "off-the-shelf" modular systems (like IKEA PAX or B&Q Atomia). This includes basic shelving, hanging rails, and perhaps a fresh coat of paint. You save significantly on labor but spend more time on assembly.

• Mid-Range (Professional): £2,000 – £5,000
Involves hiring a local joiner or using a "made-to-measure" service. This usually includes custom-sized units that fit the room's exact dimensions, including sloped ceilings or awkward corners, often using MDF or high-quality laminate.

• Premium (Bespoke): £6,000 – £12,000+
Full-service luxury installation from national brands (e.g., Sharps, Hammonds). This includes high-end finishes, integrated LED lighting, soft-close drawers, island units, and professional design/installation.

2. Cost Breakdown of Key Elements
Component Estimated Cost (UK) Notes 
Wardrobe Units £500 – £800 per linear metre Bespoke joinery/fitted wardrobes. 
Flooring £200 – £500 Based on a typical box room (4–6 sqm) for mid-range laminate or carpet. 
Lighting £150 – £400 Adding spotlights or LED strip lighting inside units. 
Decorating £200 – £400 Repainting walls and ceiling before units are fitted. 
Labor (Carpenter) £200 – £400 per day Rates are higher in London and the South East.

3. Value Impact

Converting a box room can add value if it is an "extra" room (e.g., a 4th bedroom in a 3-bed house). However, if you are removing the only spare bedroom in a small 2-bedroom home, it could potentially decrease the property's market value by reducing its "bedroom count." It is often recommended to use modular systems that can be removed if you decide to sell the house later.

Are you planning to keep any existing features like the original radiator or window, or will this be a complete "strip-back" renovation?

Hi There : Generally if standard refit : About £3000 with flat pack type installation. If custom work/infills etc about £600 and full bespoke could reach over £15k

Kal · Answer

Turning a spare bedroom into a dressing room can vary quite a bit depending on the level of joinery and finish you want. For a more straightforward fit-out using modular systems, shelving, hanging rails, and basic storage, you would usually be looking somewhere around £2,000–£5,000. For a more bespoke setup with made-to-measure cabinetry, integrated lighting, feature finishes, soft-close drawers, and higher-end materials, costs can easily reach £8,000–£15,000+. The final price normally comes down to how custom the joinery is, the amount of storage being built, electrical work, and the quality of finishes and fittings throughout.

The cost can vary quite a lot depending on the size of the room, the type of wardrobes/shelving you want, the finishes, lighting, and whether any electrical or plastering work is required.

For something like this, I would normally recommend a site visit first so I can properly assess the space and discuss the layout and design options with you. After that, I can provide you with a free no-obligation quotation.
