I didn’t set out to repaint my daughter’s bedroom at half-term. The plan was a soft reset: swap the duvet cover, maybe add a bit of storage, and have a cup of tea. What actually happened was that I noticed the scuff marks along her headboard wall, counted seven Barbie-head dents, and realised a soft reset wasn’t enough. So we drove to B&Q on the Saturday morning of half-term with a kid who was simultaneously excited and furious, and came home with everything we needed for £142.68 and a Sunday to do it.
B&Q DIY is the winner here, and I’ll say why upfront: the entire ecosystem (paint range, timber yard, storage aisle, hire tools you don’t own) sits under one shed with weekend opening hours, and the staff actually know the stock. The Valspar paint-mixing counter made the whole job feasible for a weekend turnaround. I’ve since done my son’s bedroom under the same model and the formula holds. Here’s the plan, the price, and the small things that went wrong.
Why B&Q DIY Is the Right One-Stop for a Kids’ Bedroom
B&Q DIY is the winner for a half-term bedroom refresh for three reasons that only become obvious when you try to buy the same components across different retailers. The paint-mixing counter at B&Q will match any colour from a swatch or a sample card and have 2.5L of Valspar ready in roughly 20 minutes, which is the pacing you need when you’ve got a Saturday morning and a kid losing patience by minute 40. Dulux ranges are available alongside. Prices on 2.5L mixed are around £29 to £35.
The timber yard will cut shelf pine to size for free with a 48 hour turnaround or while-you-wait on quieter weekends. Standard pine shelf planks (18mm, 240mm wide) run around £14 per metre, pre-primed MDF alternatives at £11. The storage aisle (I’ll come back to the specific products) is deep enough that you’ll find whatever system works for your room shape without resorting to Amazon.
The marketing says B&Q is “where DIY starts”. In practice it’s a 2-hour trip that would be 3 trips to different retailers otherwise, and the time saving is what makes the project a weekend job rather than a half-term job.
Weekend Timing
Saturday 9am to 10:30am for the shop, 11am to 5pm for prep and first coat, Sunday morning for second coat, Sunday afternoon to fit shelves and storage, Sunday evening to put the room back. That’s the pace that leaves Monday for the kids to actually enjoy the new room before school.
The Paint Decision: Valspar Durable Matt Over Standard Emulsion
The paint choice matters more in a kids’ bedroom than in an adult room because the walls are going to meet felt tips, muddy hands and the back of a chair pushed too hard. We used Valspar Premium Blend Durable Matt, mixed to a soft sage (“Vintage Hemp” was the swatch name), at £33.50 for 2.5L, which covered one feature wall and part of a second with one coat.
The marketing says Valspar is “wipe clean”. In practice it genuinely does wipe clean (I tested with a biro mark I made myself as a check), but you need to clean within 48 hours. Dried-in marks don’t come out as easily. The matt finish hides small wall imperfections, which matters because we weren’t filling and sanding Barbie-head dents on a weekend timetable.
The alternative we considered was Dulux Easycare Washable Matt at a similar price point. The two are close in performance in my experience, and the deciding factor was the Valspar colour range being wider for sage and dusty blue tones. Dulux has more coral and yellow range.
Rollers, Brushes and Edge Taping
A 4-inch mini roller plus a 2-inch angled brush is the kit for one wall. We used the B&Q own-brand medium pile roller at £7.80 for a pack of two, and FrogTape delicate surface tape at £8 for the edges. Delicate surface tape matters, standard masking tape pulled off a small patch of existing wall paint when we removed it on the test corner.
Floating Shelves: 3 Shelves at 60cm Each for £28
The storage reset was built around three floating shelves on the wall above the bed. Pine (planed timber) at B&Q runs about £12.50 for a 1.2m length, and the staff cut it into three 60cm shelves. Floating shelf brackets (concealed, taking 25mm into the wall) ran £5.80 per pair. Total shelf cost: £28.10 all in, including a small tin of satinwood for the ends.
The marketing says floating shelves are “a 20-minute install”. In practice if you’re drilling into plasterboard with heavy-duty fixings for a child’s room, add 20 minutes for finding studs, 15 minutes if you need a stud detector, and allow extra time for the inevitable “slightly wonky” discovery that’ll have you redoing the right-hand shelf.
Load capacity on a 60cm plasterboard-fixed floating shelf is around 4kg to 5kg if correctly fixed. That’s enough for books, soft toys and a nightlight, not enough for a heavy ceramic lamp. Fix into stud if you can find one, which doubles capacity.
Why Not IKEA Lack?
IKEA Lack floating shelves at £12.50 are cheaper, but the 30cm depth is less practical than 24cm pine, and the white laminate shows marks worse than painted timber. The build-your-own route from B&Q timber yard came in similar in price, with better aesthetics and better load capacity.
Storage Boxes and the Underbed Reset
Underbed storage was the hidden win. Three B&Q “Form Mixxit” clear plastic boxes with lids (34L capacity, around £8 each) slid under the bed perfectly, labelled on the end with chalk marker so the labels can change as the room’s needs change. Three boxes at £24 total, replacing a chaos of loose Barbies, Lego, and dress-up fabric that previously lived in a wicker basket overflowing by the wardrobe.
The marketing says the boxes are “clear for easy identification”. In practice the clear plastic matters more than I expected. My daughter can see what’s in each from the end before pulling it out, which has reduced the “I can’t find my X” morning dramas by about half.
A soft fabric cube in the corner (Dunelm sale, £12) took the dress-up fabric that didn’t fit in the hard boxes. Total storage spend: £36 including the Dunelm cube.
Decor Finishing: Posters, Hooks and a Rug Edit
Posters were the inherited bit (I didn’t buy new). The three wall hooks on the back of the door (B&Q own brand, £4.50 for three) took school hoodies, a swim bag and the dressing gown that previously lived on the floor. The existing rug stayed, washed in the machine on wool-cycle at 30 degrees, which cost nothing and transformed the room’s smell more than any air freshener.
Total decor spend new: £4.50.

Frequently Asked Questions
How much paint do I need for a single bedroom wall
A 2.5L tin covers roughly 30 square metres with one coat on a smooth wall. Standard kids’ bedroom wall is 6 to 8 square metres, so one tin does one wall two coats with leftover for touch-ups.
Is Valspar Durable Matt really wipe clean
Yes, within 48 hours. After that marks can set. Standard emulsion isn’t comparable for the price difference.
Can I fit floating shelves into plasterboard alone
Yes with heavy-duty plasterboard fixings, rated to around 4kg to 5kg per bracket. Fix into a stud where possible for heavier loads.
What’s the quickest storage upgrade for a child’s room
Three clear lidded boxes under the bed, labelled by category. Transforms morning finding time and takes 15 minutes to set up.
Does B&Q timber yard cost extra for cutting
Standard straight cuts are free, up to a limit per visit. Complex angle cuts have a small charge, typically £1 to £2 per cut.
Can I do this project with a toddler helping
Yes with a lot of planning. Paint rollers plus toddlers equals mess, but handing them clean rollers to “pretend paint” on cardboard offcuts keeps them busy for 20 minute stretches.
What about VOCs in paint for a child’s room
Valspar Premium Blend and Dulux Easycare are both low-VOC. Ventilate well for 24 hours after painting regardless, and don’t let kids sleep in the room on paint day.
Is this doable without a car
Harder. B&Q offers delivery on larger orders at £5 to £10 depending on area, and online click-and-collect saves the trip itself. Timber lengths over 1.5m need a car or a van hire slot.
