How much does a bathroom renovation cost in the UK?

The answer depends heavily on what you're starting with and what you want to achieve. A like-for-like replacement of an existing suite in a standard-sized bathroom (roughly 2m x 2m) typically costs £5,000–£8,000 including labour. Move plumbing, knock down walls, or upgrade to premium fixtures, and you're easily looking at £12,000–£18,000.

According to the Federation of Master Builders, the average UK bathroom installation costs around £6,500, though this figure masks significant regional variation. In London, expect to add 20–25% to these baseline figures. In Birmingham or Manchester, you'll generally find more competitive rates.

What factors affect bathroom renovation costs?

Size and layout changes

The most significant cost driver is whether you're working within the existing footprint or moving things around. Relocating a toilet involves moving soil pipes—potentially costing £800–£1,500 alone. Moving a bath or shower adds another £500–£1,000 in plumbing labour.

Small bathroom design ideas with shower solutions are particularly popular in UK homes where space is tight. A compact shower enclosure (700mm x 700mm) costs £200–£600 for the unit itself, whilst a larger walk-in design with frameless glass panels runs £800–£2,000.

Wet room vs walk-in shower pros cons

Wet rooms have become increasingly desirable, but they require specialist installation to meet Building Regulations waterproofing standards. The tanking (waterproofing) process adds £800–£1,500 to standard shower installation costs, and you'll need a properly formed floor gradient to a linear drain.

Wet room advantages:

• Completely level access (ideal for accessibility)
• Creates sense of space in small bathrooms
• Easier to clean without shower trays or doors
• Contemporary aesthetic appeal

Wet room disadvantages:

• Requires specialist installation skills
• More expensive initial investment (typically £1,500–£3,000 more than standard shower)
• Whole room gets wet during showering
• Potential for water damage if not installed correctly

Walk-in showers with low-profile trays offer a middle ground—easier to install than full wet rooms, but still providing that modern, open feel. These typically cost £1,200–£3,500 installed, depending on size and glass specification.

Labour costs

A qualified bathroom fitter in most UK regions charges £150–£250 per day, with London rates reaching £250–£350. Most bathroom installations require a team (fitter plus plumber and electrician) for 5–10 working days.

Expect to pay:

• Bathroom fitter/installer: £150–£300/day
• Plumber (Gas Safe registered if applicable): £180–£350/day
• Electrician (Part P certified): £150–£300/day
• Tiler: £150–£250/day
• Plasterer: £150–£200/day

Many bathroom specialists offer package rates that work out more economical than hiring individual trades. According to businesses in our browse all categories directory, full installation packages typically represent a 10–15% saving versus piecemeal hiring.

Materials and fixtures

Your choice of sanitaryware, tiles, and fittings dramatically affects the bottom line.

Item	Budget Range	Mid-Range	Premium
Toilet	£80–£150	£150–£400	£400–£1,200+
Basin & pedestal	£60–£120	£120–£350	£350–£1,000+
Bath (standard)	£150–£300	£300–£800	£800–£2,500+
Shower enclosure	£200–£500	£500–£1,200	£1,200–£3,500+
Shower valve	£80–£200	£200–£500	£500–£1,500+
Wall tiles (per m²)	£15–£30	£30–£60	£60–£150+
Floor tiles (per m²)	£20–£40	£40–£80	£80–£200+

Best bathroom tiles for small spaces

Tile selection affects both aesthetics and budget. For smaller bathrooms, we recommend:

• Large-format tiles (600mm x 300mm or bigger): Fewer grout lines create an illusion of more space. Expect to pay £30–£80/m² for decent quality porcelain.
• Light colours: White, cream, or pale grey reflect light and open up the room. Budget £20–£50/m².
• Vertical patterns: Running tiles vertically draws the eye upward, making ceilings feel higher.
• Gloss finishes: Reflective surfaces bounce light around, though they show water marks more readily than matt alternatives.

Victorian-style metro tiles remain popular and budget-friendly at £25–£45/m², whilst large-format marble-effect porcelain tiles typically cost £40–£90/m².

How much does a new bathroom cost UK: itemised breakdown

For a typical 2m x 2m bathroom with mid-range specification, here's what you'd expect to pay:

• Removal and disposal of old suite: £300–£500
• Making good walls/floor: £400–£800
• New toilet, basin, bath: £600–£1,500
• Shower enclosure and valve: £800–£1,800
• Tiling (walls and floor): £1,200–£2,500
• Plumbing labour: £800–£1,500
• Electrical work (lights, extractor, shaver point): £400–£800
• Fitting labour: £1,000–£2,000
• Finishing touches (accessories, sealant, paint): £200–£400

Total: £5,700–£11,800

These figures align with data from Checkatrade's 2024 bathroom cost survey, which found the average UK bathroom renovation costs £7,200.

Underfloor heating bathroom cost UK

Electric underfloor heating transforms a bathroom's comfort level, and it's surprisingly affordable when installed during renovation. For a standard 4m² bathroom floor:

• Electric mat system: £200–£400 for materials
• Installation: £300–£600
• Thermostat: £50–£150
• Running costs: Approximately £2–£4 per week during winter months

Total installation cost: £550–£1,150

Water-based systems (connected to your central heating) cost significantly more to install (£1,500–£3,000) but offer lower running costs if you're heating the room frequently. Electric systems make more sense for bathrooms since they heat up quickly and you're only warming a small area.

The Energy Saving Trust notes that electric underfloor heating is most cost-effective when used with a timer, heating the room 30 minutes before you need it rather than maintaining constant warmth.

How long does it take to fit a new bathroom?

A straightforward like-for-like replacement typically takes 5–7 working days. More complex renovations with structural changes, extensive tiling, or wet room installation can take 2–3 weeks.

Typical timeline:

Days 1–2: Strip out existing bathroom, first fix plumbing and electrics Days 3–4: Install new suite, fit shower enclosure, second fix plumbing Days 5–7: Tiling work Days 8–9: Grouting, sealing, finishing electrics Day 10: Final touches, clean, and handover

Be aware that discovering problems during strip-out (rotten floorboards, faulty wiring, hidden leaks) can add days to the schedule and hundreds of pounds to costs. Building in a 10–15% contingency for unexpected issues is sensible.

Do I need a wet room specialist?

Yes, absolutely. Wet room installation requires specific expertise in tanking (waterproofing) systems to meet Building Regulations Part C requirements. A standard bathroom fitter without wet room training shouldn't attempt this work.

Proper tanking involves:

• Waterproof membrane applied to floors and walls (typically 200mm up from floor level)
• Correctly formed floor gradient (minimum 1:80 fall)
• Appropriate drainage system
• Seal testing before tiling

Poor tanking leads to water damage, mould, and potentially catastrophic structural problems. The additional cost of a wet room specialist (typically £200–£400 more than standard installation) is money well spent. When browsing our search our company directory, specifically look for installers who highlight wet room certification.

Money-saving strategies for bathroom renovations

Do your own demolition

Removing the old bathroom yourself saves £300–£500. You'll need basic tools and a hired skip (£150–£250), but it's straightforward work that doesn't require special skills. Just ensure water is properly isolated before disconnecting plumbing.

Shop sales and clearance

Bathroom retailers like Wickes, B&Q, and Victoria Plum regularly run 30–50% off sales. End-of-line suites offer huge savings—we've seen £1,200 toilets reduced to £400 simply because they're discontinuing that colour.

Keep plumbing where it is

The single biggest cost saver is working within your existing layout. If the toilet, basin, and bath/shower locations work reasonably well, leave them there. You'll cut plumbing costs by 50–70%.

Consider a shower-only bathroom

Removing a bath and installing a large walk-in shower creates a more spacious feel and typically costs £500–£1,000 less than bath-plus-shower configurations. Unless you regularly take baths or have young children, it's worth considering.

Mix budget and premium items

Splurge on the elements you'll notice and use daily (shower valve, taps, tiles), but save money on hidden items like the toilet cistern or pedestal basin. Nobody will know your toilet cost £120 rather than £400, but they'll definitely notice a premium rainfall shower.

Get multiple quotes

Prices vary enormously between installers. We recommend getting at least three detailed quotes. If you're looking for trusted professionals, list your business on HouseJester if you're a bathroom specialist, or search our verified bathroom specialists if you're a homeowner.

Comparison: bathroom renovation options

Renovation Type	Cost Range	Duration	Best For	Considerations
Basic refresh	£2,000–£4,000	3–5 days	Rental properties, quick sale preparation	Paint, new suite, minimal tiling
Standard replacement	£4,000–£8,000	5–10 days	Most family homes, like-for-like upgrades	Same layout, mid-range fixtures
Full renovation	£8,000–£15,000	10–15 days	Reconfiguration, adding value	Layout changes, premium materials
Luxury installation	£15,000–£30,000+	15–20 days	High-end homes, maximum comfort	Designer fixtures, smart technology, bespoke elements

Regional price variations

Bathroom renovation costs vary significantly across the UK:

• London and South East: 20–25% above national average (£8,000–£10,000 for standard bathroom)
• South West: 10–15% above average
• Midlands and North: Closest to national average (£5,000–£7,000)
• Scotland, Wales, Northern Ireland: 5–10% below average
• Rural areas: Can be 10–15% higher due to travel costs and limited competition

These variations reflect both labour costs and material delivery charges. London plumbers charging £300+ per day aren't being greedy—they're dealing with higher business rates, congestion charges, and cost of living.

Building Regulations and compliance

Bathroom renovations must comply with several Building Regulations:

Part C (Site preparation and resistance to contaminants and moisture): Waterproofing requirements, particularly critical for wet rooms

Part L (Conservation of fuel and power): Extractor fan specifications, lighting efficiency

Part M (Access to and use of buildings): Relevant if adapting for accessibility

Part P (Electrical safety): All electrical work must be certified by a qualified electrician

Most bathroom installers handle Building Regulations compliance, but confirm this in writing before work begins. Electrical work must be certified—ask for your Part P compliance certificate on completion.

Final thoughts

Bathroom renovations represent one of the best value home improvements, typically returning 70–80% of costs in added property value according to Homebuilding & Renovating magazine. More importantly, you'll enjoy the space daily for years to come.

Planning thoroughly, getting detailed quotes, and choosing the right bathrooms specialist makes the difference between a smooth project and a stressful experience. Take time to research materials, visit showrooms, and speak to multiple installers before committing.

Your bathroom renovation UK project doesn't need to break the bank, but it does need proper planning and realistic budgeting. Factor in that 10–15% contingency, expect the unexpected, and you'll end up with a bathroom you'll love for years to come.
