The family bathroom is where every parenting stress converges. It’s small, it’s damp, it needs to be safe for a two-year-old who thinks the loo brush is a microphone, and it usually gets renovated last because you keep telling yourself you’ll get to it after the summer. We spoke to four mums who did a full family-bathroom refresh over a long weekend in the last twelve months, and the pattern was consistent. B&Q’s DIY kits and off-peak weekday prices were the pick for anyone doing this without a plumber’s contract and a five-figure budget.
None of what follows is about a full strip-out replacement of soil pipes and floor joists. That’s a professional job. This is the realistic version, replacing tiles, taps, loo seat, vanity unit, splashbacks, lighting and paint over three days, with the sink and toilet staying where they are. Real budgets are £800 to £2,500 depending on how much you swap out. Real time is two to three days if two adults are working and the kids are staying at grandma’s.
Why B&Q wins for family bathrooms
B&Q’s advantage over Wickes and Homebase for family renovations is boring but real. Their DIY bathroom kits are packaged for people who aren’t tradesmen. A £329 vanity-and-tap bundle from B&Q comes with the vanity, the tap, the waste, and clear step-by-step instructions that assume you don’t own a torque wrench. Wickes will sell you the same components, often at similar prices, but they don’t bundle them the same way and their in-store staff push you towards their fitter service. Homebase has scaled back its bathroom range so much in the last two years that it’s rarely worth the trip.
Toddler safety is where B&Q genuinely pulls ahead. Their basic thermostatic mixer showers cap the maximum temperature at 38 degrees at the head, which matters when a curious three-year-old works out how to turn the tap. The Cooke & Lewis range, which is B&Q’s own brand, does anti-slip bath mats sized for shorter baths, soft-close loo seats that won’t trap little fingers, and low-splash tap designs that don’t send water halfway across a tiled floor. None of this is revolutionary. It’s just packaged and priced for parents rather than for design magazines.
Click and collect matters more than you’d think when you’re mid-renovation. B&Q’s collection turnaround is usually two to four hours for in-stock items, which means if you get halfway through Saturday morning and realise you need a different waste trap, you’re not losing the day. Wickes has similar systems but stock is less consistent in smaller stores. Screwfix, which is owned by B&Q’s parent group, is your best emergency friend for fittings and screws but doesn’t do full bathroom kits.
What “off-peak” prices actually mean
The bathroom trade runs on a cycle. Prices peak in April and May when everyone decides to redo their bathroom before summer, and again in September when the autumn nesting kicks in. Off-peak windows are late January to mid-February and mid-October to early November. B&Q’s own-brand ranges drop 20 to 30 percent in these windows. A £129 tap becomes £89. A £249 vanity becomes £179. If your renovation isn’t urgent, timing it to these windows saves a hundred or two on a small bathroom refresh.
The £800 refresh, done in a weekend
If your bath, sink and loo are in good shape and you just need to lift the room, £800 is enough for a proper refresh. Budget breakdown for a small family bathroom, roughly 5 square metres.
Wall paint suitable for bathrooms costs £22 to £28 for 2.5 litres of a moisture-resistant range like Dulux Easycare Bathroom or B&Q’s own Bathroom Plus. Two coats on the non-tiled walls takes half a Saturday. New taps for a basin and bath from the Cooke & Lewis range run £45 to £85 each. A soft-close loo seat is £29. A toddler-height step stool is £15. A vinyl floor click-tile that goes over your existing floor costs £110 to £180 for a small room and installs in three hours with no adhesive.
The remaining budget covers a mirror, LED bathroom light, a couple of new towel rails, and a small ventilation upgrade if the extractor fan is on its last legs. This is the version that changes the feel of the room without changing the plumbing. Real mums we spoke to said this refresh took two days with one adult working, or one long day with two.
The £1,500 to £2,500 renovation
Once you swap the vanity, retile a wall, and add new lighting, you’re in the middle bracket. This is where B&Q’s bundles start to pay off. Their Ashford or Perma vanity bundles at £329 to £479 include the vanity, tap, waste and mixer, and can be fitted by a competent DIYer in three to four hours. Retiling a single splashback wall in a small bathroom uses roughly one square metre of tiles at £25 to £45 depending on the range, plus £15 for adhesive and grout. If you’re keeping the existing tiles in reasonable shape, tile paint from Ronseal at £20 a tin covers a square metre of tiles and lets you change the colour without pulling anything off the wall.
New LED lighting from the B&Q Colours range starts at £29 for an IP44-rated ceiling light suitable for zone one bathroom use. Underfloor heating mats for a small bathroom, if you’re lifting the floor anyway, cost £180 to £280 for a 3 square metre kit that installs with a self-adhesive backing. The heating is a genuine notable shift with toddlers who otherwise hop about on cold tiles after bath time.
The toddler-safe checklist
Before you buy anything, work through this list. A thermostatic mixer bar shower cap at 38 degrees is non-negotiable if the kids will ever operate the shower alone. Soft-close loo seats prevent trapped fingers and are £15 to £30. A non-slip bath mat inside the tub, not just a rug outside, cuts the biggest slip-and-fall risk in the house. Rounded-corner vanity units are worth the extra £20 to £40 when a toddler is at head-bump height. Anti-scald tap covers are £8 to £12 and worth every penny for hot brass taps in a busy family bathroom. A door lock that can be unlocked from outside with a coin is essential, because a two-year-old will lock themselves in eventually.
Comparison table
| Store | Budget kit (vanity + tap + waste) | Own-brand tile range price per sq m | Click and collect turnaround | Toddler-safe options |
|---|---|---|---|---|
| B&Q | £329 to £479 (Cooke & Lewis) | £22 to £45 | 2 to 4 hours | Strong, well signposted |
| Wickes | £299 to £499 | £20 to £48 | 4 to 24 hours | Moderate, less obvious |
| Homebase | £249 to £399 | £22 to £42 | 24 to 48 hours | Limited range |
| Screwfix | Fittings only, not full kits | Not stocked | 1 to 2 hours | Not applicable |
Where the other stores earn a look
Wickes is a fair second choice, and for anyone who lives closer to a Wickes than a B&Q, the range is honestly close. Their trade counter opens earlier, which matters on a Saturday morning. Homebase is where you go for the finishing touches, mirrors, storage baskets, small furniture, but their core bathroom range has shrunk. Screwfix is the emergency lifeline for that missing waste washer or the wrong-sized screw at 5pm on a Sunday.
Bathstore, which used to be the specialist option, no longer exists in most towns after the retail collapse a few years back. Its stock ended up dispersed through independent trade merchants, some of which are excellent but require you to know what you’re asking for. If you’re new to bathroom DIY, stick with the big four.
What actually fits with toddlers
The plans people share online usually assume adults using a bathroom the way adults do. Real family bathrooms have to survive bath toys spilling out of every corner, wet footprints on the floor, and a small child who wants to climb everything. Wall-mounted storage above the loo is your best friend. Low storage that a toddler can pull open should have magnetic soft-close doors, not conventional handles they’ll swing on. A recessed shelf inside the shower or bath, at adult chest height, keeps shampoo bottles out of small hands.
The bath itself is a design decision. A standard 1700mm bath is fine for a family, but if you have space consider a 1600mm shorter bath with a slightly deeper profile. Toddlers slip less in a shorter bath and adults can still soak. Corner baths are largely a waste of space in family bathrooms because the corner geometry means less floor space for wet children clambering out.
Ventilation and damp, the boring bit
The most-forgotten renovation upgrade is the extractor fan. A family bathroom with two showers a day and a bath at bedtime produces genuinely serious amounts of moisture. If your fan is a squeaky white plastic thing that came with the house, replace it while you’re doing everything else. A quiet DC-motor fan with a humidity sensor from Envirovent or Manrose costs £45 to £80, and stops mould from taking hold in the grout you just replaced. This is a fifteen-minute swap for an electrician or a well-briefed DIYer, and it’s cheaper if you do it while you already have the ceiling light down.

Frequently Asked Questions
Can I actually renovate a family bathroom in a weekend
For a refresh, yes. For a full strip-out replacement of the bath, sink and loo including plumbing, no. A realistic weekend project keeps the fixtures in place and changes taps, vanity, tiles, paint, lighting and flooring. Two adults working can complete this in two to three days.
Is B&Q genuinely cheaper than Wickes for bathroom DIY
On like-for-like items, prices are within a few pounds of each other. B&Q’s advantage is bundling, off-peak sale windows, and clearer instructions in the own-brand kits. If your local Wickes is closer, use Wickes. Don’t drive twenty miles for a fiver.
When are the best off-peak windows for buying bathroom kits
Late January to mid-February and mid-October to early November. Own-brand ranges typically drop 20 to 30 percent in these windows. Sign up for the B&Q emails a month before to catch the codes.
What’s the single most important toddler-safety upgrade
A thermostatic mixer that caps the water temperature at 38 degrees at the head. Scalding injuries are among the common toddler bathroom accidents, and this one fitting prevents almost all of them.
Do I need a professional plumber for any of this
For fixture replacement in the same location, using existing pipework, a competent DIYer can usually handle it. If you’re moving the position of the loo, sink or bath, or altering pipework in walls, use a Gas Safe plumber for anything gas and a qualified plumber for anything else. Building regulations apply to some works even for DIY.
How do I keep grout looking clean in a family bathroom
Use epoxy grout instead of standard cement-based grout if you’re retiling. It’s slightly more expensive at around £20 versus £12 for a tub, but it doesn’t stain and doesn’t need annual scrubbing. Seal the joints between the bath and the wall with a good silicone rather than a cheap one.
Is underfloor heating worth it for a family bathroom
Yes, if you’re lifting the floor anyway. The electric mat kits for small rooms are affordable and the difference in comfort for children stepping out of the bath is noticeable. Retrofitting later means lifting the new floor again, which is expensive.
What ventilation should I fit in a family bathroom
A DC-motor extractor fan with a humidity sensor. It runs quietly, only kicks in when moisture rises, and stops mould from establishing in grout and sealant. Manrose and Envirovent both do reliable options at £45 to £80.
