Pricing note: Bathroom renovation costs vary mainly by specification rather than region, though London labour rates add 15–25% compared to national averages. The biggest cost driver is usually sanitaryware and tile specification — a budget suite in a standard bathroom can cost as little as £3,000 all-in, while a bespoke premium renovation can exceed £15,000+.

Bathroom Fitters Who Do It Properly

A bathroom renovation involves plumbing, electrics, waterproofing, tiling and fitting — often in tight spaces, with strict Building Regulations requirements for ventilation, electrics and wet area waterproofing. A poorly fitted bathroom causes water damage, mould and expensive remedial work. Getting a qualified fitter matters.

BestBuilders connects you with APHC-qualified bathroom fitters who manage the full project: strip-out, first fix plumbing and electrics, boarding, tanking, tiling, suite installation, second fix and snagging. Whether you're refreshing a tired bathroom or installing a new en-suite from scratch, we match you with fitters who get the detail right.

Every fitter in our network is verified for insurance, qualifications and genuine customer reviews before they receive a single lead from us.

Cost Factors

What Affects the Cost of a Bathroom Renovation?

Bathroom renovation quotes can vary dramatically for the same room size. Here's what drives the difference.

🚿 Sanitaryware specification

The single biggest cost variable. A complete suite from a budget range (e.g. B&Q, Victorian Plumbing) starts from £500–£1,000. A premium branded suite (Duravit, Ideal Standard, Villeroy & Boch) can cost £3,000–£8,000+ for the suite alone. Always separate supply and installation in your quote requests.

🪟 Tiles and flooring

Tile cost ranges from £15/m² for basic ceramic to £150+/m² for large-format porcelain or natural stone. A standard bathroom uses 15–25m² of tiles. Underfloor heating adds £400–£1,200 for a bathroom. The difference between budget and premium tile choices alone can be £2,000+.

🔧 Services complexity

Moving the toilet, adding a bath where there was only a shower or relocating the soil pipe significantly increases costs. Like-for-like replacements are much cheaper than full reconfigurations. Electric shower changes are relatively quick; thermostatic mixer showers require more plumbing work.

💧 Wet room waterproofing

Wet rooms require specialist tanking of the entire floor and wet walls — typically adding £500–£1,500 over a standard shower enclosure installation. The tanking system must be done correctly; leaks caused by poor waterproofing can cause serious structural damage. Only use fitters with wet room experience.

🏗 En-suite creation

Creating a brand new en-suite from a bedroom space involves partitioning, structural checks for floor loading, new soil pipe runs and potentially a new ventilation stack. This is more complex than a like-for-like bathroom renovation and typically adds £2,000–£5,000 to the cost of the bathroom itself.

📍 Access and location

London labour rates run 15–25% above national averages. Upper-floor bathrooms with limited access, or flats with no goods lift, can add time and cost for material delivery. Always get local quotes — use our town-specific cost guide.

Customer Reviews

What Homeowners Say About Our Bathroom Fitters

★★★★★ 4.8 / 5
★★★★★

Three quotes for our family bathroom renovation within 24 hours. All fitters were clearly experienced — they noticed our existing tanking had failed and told us before they priced it. The one we chose did an outstanding job. Tiling is immaculate.

Sam B.
Leeds, Yorkshire
Standard Bathroom
★★★★★

We wanted a new en-suite created from part of a bedroom. BestBuilders matched us with a fitter who'd done dozens of these. Handled the partitioning, soil pipe run and full fit. Beautiful result — couldn't be happier with the space.

Karen A.
Altrincham, Manchester
En-Suite Bathroom
★★★★☆

Had a luxury wet room fitted — frameless glass, large-format porcelain and underfloor heating. The fitter BestBuilders found was a genuine wet room specialist. Tanking and drainage done perfectly. Worth every penny and the quotes were fair.

Common Questions

Bathroom Renovation FAQs

A straightforward like-for-like bathroom renovation typically takes 5–10 working days. A more complex project — moving the layout, creating a new en-suite or installing a wet room — can take 2–3 weeks. Lead times for sanitaryware and tile delivery can extend the overall programme if you're ordering bespoke or long-lead items. Your fitter will confirm the programme before work starts and advise on any items to order in advance.
No — a standard bathroom renovation does not require planning permission. Building Regulations do apply to certain elements: electrical work in bathrooms must comply with Part P (and be certified by a registered electrician), and any work involving gas requires a Gas Safe registered engineer. If you're creating a new en-suite by partitioning a bedroom, you may need to notify building control, particularly if structural changes are involved.
Both work well. Supplying your own sanitaryware gives you full control over the specification and often reduces cost, since you're not paying a fitter's markup on goods. A supply-and-fit service can be more convenient and means the fitter takes responsibility for the suite fitting correctly. For premium or bespoke sanitaryware, many homeowners buy directly from specialist bathroom showrooms and hire a fitter separately — this is a common and cost-effective approach. Tell your matched fitters which approach you prefer.
A wet room is a fully waterproofed (tanked) shower room where the shower area has no enclosure or tray — water drains through a floor-level drain. Wet rooms suit larger bathrooms and are particularly popular as accessible bathrooms for older adults. For smaller rooms, a good shower enclosure is often more practical and less expensive. The critical requirement for a wet room is specialist waterproofing: the floor and walls must be properly tanked to prevent leaks — always use a fitter with proven wet room experience.
The Association of Plumbing & Heating Contractors (APHC) is the UK's leading trade body for plumbing and heating professionals. APHC-registered members have been vetted for competence, hold relevant qualifications and carry appropriate insurance. For bathroom renovation, where the quality of plumbing work directly affects water safety and the risk of leaks, APHC registration is a meaningful quality indicator. All bathroom fitters in the BestBuilders network are verified for APHC membership or equivalent qualification.
No — once the strip-out begins, the bathroom will be out of use until work is complete. If you only have one bathroom, this is an important consideration. Most fitters will work continuously to minimise the downtime. For a 7-day project, you'll typically have the toilet reinstalled and functional by day 4–5, with the shower or bath following shortly after. If you have only one bathroom and no other facilities, discuss the sequencing with your fitter before work starts — some will prioritise restoring WC access quickly.
Full bathroom renovation (£3,000–£20,000) replaces an existing bathroom with new bath, shower, basin, toilet, tiling and lighting. En-suite (£3,000–£18,000) is a smaller adjacent bathroom typically off the master bedroom — same scope, less floor area. Wet room (£4,000–£30,000) eliminates the shower tray and tanks the whole floor — premium fitting requiring full waterproofing, level-access drainage and skilled installation. Wet rooms cost 40-60% more than equivalent en-suites.
A standard bathroom renovation takes 5–10 working days on site once materials are delivered. Add 2–6 weeks lead time for special-order sanitaryware or imported tiles. Wet rooms take 2-3 days longer due to tanking and drainage work. If you're moving plumbing locations, expect an extra 1-2 days. Most homeowners are without their main bathroom for the full duration — a secondary bathroom or temporary shower arrangement is essential during renovation.
Like-for-like replacements (bath, basin, toilet in original positions) don't need plumbing changes — saves £800–£2,500. Moving plumbing adds 1-3 days and £800-£3,500 depending on distance and floor type (concrete floors cost more than timber). Common moves: rotating the toilet, swapping bath for shower, adding a second basin. Soil-stack and waste-pipe positions are the hardest to change — try to design around existing positions where possible.
No for like-for-like renovations within the existing footprint. You DO need Building Regulations approval for new electrical circuits (Part P), any structural alterations, and changes to drainage. If you're converting a bedroom or other room into a bathroom, planning permission isn't needed but ventilation and waste connection compliance is. Listed buildings may require Listed Building Consent. Your installer will advise during the design phase.
Yes — bathrooms are classed as "special locations" under UK Building Regs Part P. Any new circuits, electric showers, extractor fans, or new lighting positions must be installed by a Part-P qualified electrician and certified to Building Control. Self-certification routes (NICEIC, NAPIT, ELECSA) avoid the cost of a separate council inspection. All metal pipework and fixtures within "zones" must be earth-bonded. Your bathroom fitter will sub-contract Part-P work if not qualified directly.
Yes — a quality bathroom renovation typically adds 3–5% to property value, with en-suite additions adding 4-6%. Adding a SECOND bathroom (from a 1-bath to 2-bath home) is highest-ROI: 10-20% value uplift in markets where 2+ baths are standard for the home type. Spending beyond £15-£20k on a single bathroom rarely recoups full cost on sale — match spec to neighbourhood comparables. Wet rooms appeal to specific buyers (accessibility, modern aesthetic) but narrow your potential buyer pool.
UK Building Regs Part F requires mechanical extraction of at least 15 litres/second in bathrooms and 30 l/s in wet rooms. Window ventilation alone is not sufficient. Options: basic extractor fan (£60-£200 fitted) with humidistat or timer; centralised MVHR (mechanical ventilation with heat recovery, £1,500-£4,000 for whole house) — best for wet rooms and modern airtight builds. Poor ventilation causes mould, peeling paint and damaged grout — don't skimp here.
Separate warranties apply: Sanitaryware (bath, basin, toilet) — manufacturer 10-25 years; Brassware (taps, showers) — typically 5-10 years; Tiles & grout — workmanship warranty 1-2 years; Installation — your fitter's 12-month guarantee covering leaks, fixings, snagging. Wet rooms typically include a separate waterproofing warranty on the tanking system (10-25 years from the manufacturer if installed by an approved contractor). Keep all paperwork — claims require proof of qualified installation.
