Average Bathroom Renovation Cost in Balham 2025
Bathroom renovation costs in Balham generally run from £5,000 to £12,000 for a typical project. The actual number depends on the scope and the materials you choose.
Labour rates in Balham and your bathroom’s size are big factors in what you’ll pay.
Typical Price Ranges by Renovation Type
A full bathroom renovation in Balham usually costs £8,000 to £11,000 for a standard spec with mid-range contractors. Basic jobs start closer to £5,000, while high-end projects can top £15,000.
Ensuite bathrooms land between £6,500 and £9,500. They’re smaller, so you use less material, but labour rates per square metre are similar.
WC-only renovations are the most affordable—expect to pay £3,000 to £4,000.
Your renovation budget splits into a few main chunks. Plumbed appliances take about 35%. Wall prep and finishes are around 21%. Flooring soaks up another 14%. The rest goes to decoration, electrics, fixtures, and those “preliminaries” that always seem to pop up.
Regional Costs and Pricing Trends
Balham’s in Greater London, so you’re looking at bathroom renovations that cost 6–8% more than the UK average.
A typical mid-benchmark contractor charges £10,000 to £11,200 for a standard bathroom here.
Some Balham projects get Inner London rates, which can push things up to £11,200 for similar work. Your postcode and where your contractor is based both matter.
South London contractors usually fall between the outer and inner London price points.
Labour costs in Balham are higher, reflecting the area’s competitive market. You’ll pay £1,650 to £1,900 per square metre for standard jobs. Premium contractors can charge more than £2,000 per square metre.
How Renovation Size Affects Overall Spend
Bathroom size really matters. A 6-square-metre bathroom runs £10,000 to £11,500, while a 4-square-metre space comes in at £8,000 to £9,500.
Per-square-metre pricing drops a bit as bathrooms get bigger. Small bathrooms cost £2,200 to £2,500 per square metre, but big ones go down to £1,700 to £1,900. Fixed costs like plumbing and electrics get spread out in larger spaces.
Your layout can make things tricky. Odd-shaped rooms or moving fixtures around will add labour hours. Shifting plumbing? That’s another £500 to £1,500.
Full Bathroom Renovation Cost Breakdown
A full bathroom renovation in Balham usually lands between £4,500 and £7,500, but luxury projects can go well over £14,000. You’re mainly paying for labour, materials and fixtures, plus extras like waste disposal and VAT.
Labour Charges and Professional Fees
Labour eats up about 40–50% of your total cost. Plumbers in Balham charge £40 to £60 per hour, and bathroom fitters want £320 to £480 per day.
Most full bathroom jobs take 5 to 10 days, so you’re looking at £1,600 to £4,800 for labour.
You’ll also need other trades. Electricians charge £45 to £60 an hour for things like new lighting or towel rails. Tilers are about £300 per day. Plasterers and decorators run £250 to £350 per day if you want fresh walls or paint.
Changing the layout or moving plumbing? That’s extra—rerouting pipework can bump labour up by 20–30%.
Materials, Fixtures, and Fittings
Materials and fixtures make up the other half of your bill. Your choices here have a huge impact.
A standard toilet is around £250. A basic sink comes in at £150. Bath installation averages £850. Showers cost £350 to £600 to fit.
Tiles are all over the place—£20 to £400+ per square metre. Budget tiles save money, but natural stone or designer ceramics can really add up.
Flooring ranges from £10 per square metre for vinyl to £80+ for high-end wood.
Don’t forget taps, shower heads, cabinets, mirrors, and lighting. Mid-range fittings usually total £800 to £1,500. Go for high-end or bespoke, and things like a walk-in shower (£200 to £2,000) or underfloor heating will push your materials budget up a lot.
Waste Disposal and VAT
Getting rid of your old bathroom suite costs £600 to £1,000. This covers disconnecting and disposing of your bath, toilet, sink, and shower.
You’ll probably need a skip—budget about £320 per week for a 6 to 8 yarder.
VAT is 20% on both labour and materials. On a £5,000 job before VAT, you’ll pay an extra £1,000, so your total is £6,000.
Some trades include waste disposal in their quotes, others don’t. Always check what’s included before signing anything.
Partial Renovations and Budget Upgrades
You don’t have to rip everything out to make your bathroom feel new. Targeted updates and smart refurbishments can refresh your space for £800 to £3,500 in Balham, depending on what you tackle.
Refurbishment Versus Replacement
Refurbishing what you have is way cheaper than replacing it all. You can resurface a bath for £300 to £500, instead of paying £850 for a new one.
Reglazing tiles costs £25 to £40 per square metre. Full retiling (including labour) is £200 to £400 per square metre.
Re-enamelling sanitaryware can add 10–15 years of life for about 30% of the cost of new. Swapping cabinet doors or painting them costs £150 to £400, while new units are £600 to £2,000.
Replacement makes sense when things are beyond repair or if you’re changing the layout. Swapping old toilets for modern dual-flush models saves water and might even get you a rebate.
Cost-Effective Upgrade Options
New taps make a big difference for £50 to £200 per set. Changing cabinet handles or towel rails costs just £30 to £100.
Better lighting helps too. LED downlights are £15 to £40 each, plus £45 to £60 per hour for an electrician. Mirrors with integrated lights cost £100 to £300.
Fresh grouting is only £150 to £250 and can make tiles look new. Painting with moisture-resistant paint costs £200 to £400, including labour.
A new shower screen runs £150 to £500, depending on what you pick.
These upgrades can really lift your bathroom without the chaos or cost of a total overhaul.
Key Cost Drivers in a Balham Bathroom Renovation
Your Balham bathroom renovation price depends on a few big factors. Layout changes, room size, and the quality of materials matter most.
Layout Changes and Plumbing Complexity
Moving toilets, sinks, or showers to new spots adds serious expense. Relocating plumbing usually costs £800 to £2,000, depending on how tricky it is. Keep fixtures where they are, and you’ll skip these costs.
Structural changes like taking out walls or making new doorways mean building control approval and specialist labour. These jobs can add £1,500 to £5,000 to your bill.
Older Balham homes sometimes need plumbing upgrades to meet current rules.
Want a bathroom in a new spot or converting a bedroom? You’ll need all-new waste pipes and water lines, starting at £3,000 before you even pick fixtures.
Impact of Bathroom Size
Room size drives up material and labour needs. Small bathrooms under 3 square metres cost about £1,500 to £2,000 per square metre for standard specs. Bigger bathrooms—over 6 square metres—may cost a bit less per square metre.
Tiling costs rise fast with bigger spaces. More tiles, more adhesive, more time.
Prepping floors and waterproofing also scale up with size.
Tiny bathrooms have their own headaches. Fitters might need special tools or extra time in tight quarters. Custom fixtures for small rooms can actually be more expensive.
Quality of Fixtures and Finishes
Your bathroom suite choice has a huge effect on your budget. Basic combos (toilet, basin, shower) cost £400 to £800. Mid-range brands run £1,000 to £2,500. Premium or designer pieces? £4,000 and up, easily.
Tiles are another big variable. Standard ceramic is £15 to £30 per square metre. Porcelain or natural stone jumps to £40 to £100. Designer tiles? £150+ per square metre.
Here’s a quick look at typical fixture prices:
- Taps: £50 (basic) to £400+ (premium)
- Shower enclosures: £200 to £1,500
- Vanity units: £150 to £2,000
- Heated towel rails: £80 to £600
Labour costs don’t change much with fixture quality, but complex premium products can take longer to install.
Popular Features and Their Cost Impact
Adding modern features definitely bumps up your Balham bathroom budget.
Walk-in showers usually add £1,500–£3,500. Underfloor heating is £500–£1,200, depending on room size. Tiles can be anywhere from £15–£150 per square metre.
Walk-In Shower Installation
Walk-in showers in Balham cost £1,500 to £3,500, depending on size and finish.
Basic setups with standard glass and simple drainage are cheaper. Go for frameless glass, rainfall heads, and linear drains, and the price climbs.
That cost covers waterproofing, tray or wet room floor, screen fitting, and plumbing. If you’re converting from a bath, expect to pay more for drainage changes and floor levelling.
Screen quality makes a difference. Thicker glass (8–10mm) with chrome or brass fittings costs more but looks and lasts better. Budget screens use 6mm glass and basic seals that might not last as long.
Underfloor Heating Expenses
Underfloor heating in a typical Balham bathroom runs about £500-£1,200 for electric systems. This covers heating mats, a thermostat, and professional installation under your floor tiles.
Electric systems heat up fast and don’t need a connection to your central heating. They’re usually the best pick for bathrooms.
Water-based systems cost more—think £1,500-£2,500—but work better for bigger bathrooms or if you’re doing the whole house.
Installation adds an extra 1-2 days to your renovation. The fitter has to level the floor, lay insulation boards, position the heating mats, and wait for everything to dry before tiling.
Running costs stay low, usually about £1-£2 per week during winter.
Tile Choices: Porcelain, Ceramic, and Mosaic
Porcelain tiles in Balham cost £25-£80 per square metre. They’re tough and handle water really well.
Ceramic tiles are cheaper at £15-£40 per square metre, but they chip more easily if your bathroom sees a lot of action.
Mosaic tiles look fantastic on feature walls, but they’re pricier. Expect £40-£150 per square metre for good mosaics, and labour costs jump 30-50% because of all the cutting and grouting.
Large-format porcelain tiles (600x1200mm) give a modern vibe and fewer grout lines. They cost more per tile, but you cover more area and spend less time cleaning.
Your tile choice affects both what you pay upfront and how much time you’ll spend scrubbing later.
Budgeting, Planning, and Saving Strategies
A bathroom renovation in Balham usually falls between £8,000 and £11,000 for a standard job. Your choices—materials, labour, and the surprises that always pop up—decide the final bill.
Proper budgeting keeps things on track and helps you get the quality you want.
Setting a Realistic Renovation Budget
You’ll want to account for every part of the project, not just the obvious stuff. In 2025, a mid-range bathroom renovation in Greater London averages about £11,151 with a mid-level contractor.
That works out to around £1,858 per square metre.
Here’s a typical cost breakdown:
| Project Stage | Percentage of Total |
|---|---|
| Plumbed appliances | 35.3% |
| Wall preparation and finishes | 21.0% |
| Floor preparation and finishes | 14.0% |
| Decoration | 10.6% |
| Wired appliances | 7.2% |
Set aside an extra 10-15% of your budget for unexpected hiccups. That safety net helps when demolition or installation uncovers something ugly.
Managing Expectations and Hidden Costs
Hidden costs can sneak up fast. Structural issues like rotten floorboards, old plumbing, or poor ventilation often show up only after work kicks off.
Getting rid of your old suite, tiles, and waste usually adds £200-£400. Moving your toilet or adding new fixtures? You’ll need Building Regulations approval, and that’s another £150-£250.
VAT bumps up all labour and materials by 20% unless you qualify for a discount. If there’s water damage behind walls or under floors, you’ll need to fix it right away to prevent bigger headaches.
If you have just one bathroom, plan for temporary arrangements while work’s underway.
Working With Local Bathroom Fitters
Local bathroom fitters in Balham know the area and can often source materials faster than big national chains. Always ask for itemised quotes from at least three contractors so you’ve got a fair comparison.
Ask for references from recent jobs within 5 miles. Fitters familiar with Balham’s Victorian and Edwardian homes can spot common issues before they become problems.
Check if they’re members of professional bodies like the Federation of Master Builders or TrustMark. These accreditations mean they meet certain standards.
Discuss payment schedules before work starts. Most go with 25% upfront, 50% at the halfway mark, and the last 25% on completion. Don’t pay it all at once.
Frequently Asked Questions
Bathroom renovation costs in Balham usually range from £2,000 to £10,000, though luxury projects can go above £20,000. The final number depends on your bathroom’s size, the quality of your materials, local labour rates, and whether you’re making structural changes.

For 2025, expect to pay between £2,000 and £10,000 for a standard bathroom renovation in Balham. Most people spend around £6,000 for a full upgrade—new fixtures, tiling, plumbing, and lighting.
A small bathroom with basic fixtures and no major changes usually costs £1,500 to £5,000. Larger family bathrooms with mid-range materials and some layout tweaks will land at the higher end.
Labour rates in Balham are what you’d expect for London. Plumbers charge £40 to £80 an hour. Tilers ask for £200 to £350 a day.
How much should I budget for a high-end bathroom refurbishment in Balham?
A luxury bathroom in Balham? You’re looking at £8,000 to £20,000 or even more. That covers premium fixtures, designer tiles, underfloor heating, and top-notch finishes.
Costs shoot up if you want things like walk-in showers, freestanding tubs, or smart tech. Custom cabinets and bespoke designs add to the total.
Natural stone baths and specialist fixtures can push your spend well past £20,000. Wet rooms, with all the waterproofing and drainage work, usually cost between £3,500 and £12,000, depending on size and materials.
What are the essential factors that influence the price of a bathroom remodel?
The size of your bathroom is a big deal—bigger means more materials and more labour. That adds up fast.
Your choice of fixtures matters, too. Basic toilets might cost a couple hundred pounds, but high-end models can run into the thousands. Same for baths—acrylic is cheaper, cast iron or stone is pricey.
Labour costs in Balham reflect London’s higher cost of living. If your project needs major plumbing changes or structural work, expect to pay more than for a simple refresh.
Can I save on my bathroom renovation costs by doing some of the work myself?
You can definitely save by taking on some tasks yourself. Painting and decorating are pretty straightforward, and you could pocket £200 to £600 in savings.
Removing old fixtures and prepping the space before the pros arrive also cuts down on labour hours. Sourcing your own materials might help, but tradespeople often get better deals through their suppliers.
Leave plumbing and electrical work to the qualified professionals. DIY mistakes here can be costly—and dangerous. It’s usually cheaper to get it right the first time.
What are the current trends in bathroom design and how might they affect renovation costs?
Walk-in showers and wet rooms are still big in 2025. These need proper waterproofing and drainage, so installation costs run from £3,500 to £12,000, depending on what you want.
Underfloor heating is pretty much standard now. You’ll pay £100 to £130 per square metre to install, but it adds comfort and frees up wall space by ditching radiators.
Smart bathroom tech—digital showers, hands-free toilets—adds to the budget. These features are cool and convenient but come with a higher price tag.
Moisture-resistant materials and good ventilation (think extractor fans at £100 to £300) are still key for keeping mould away and air quality decent.
How do building regulations in Balham impact the budget for a bathroom renovation?
Internal bathroom renovations in Balham usually don’t need planning permission. Still, you have to follow building regulations, especially when it comes to electrical work, ventilation, and any structural changes.
All electrical work in a bathroom has to meet strict safety standards. It’s best to hire a qualified electrician who knows the ins and outs of bathroom installations.
You’ll also need to install proper ventilation. Extractor fans typically cost somewhere between £100 and £300, but they’re essential to prevent moisture damage.
If you’re moving or adding new plumbing, make sure the work sticks to water regulations. For bigger changes—like removing a wall or changing floor levels for a wet room—building control has to sign off.
These compliance costs aren’t really optional. If you skip them, you might end up with expensive problems down the line.
