Bathroom Fitting Costs UK — Full Installation, Wet Room and En-Suite Pricing Guide (2026)

Bathroom fitting is one of the most complex domestic renovation jobs to price accurately. It involves multiple trades, variable material costs, and significant hidden risks — from pipework buried in walls to structural issues only visible when the old suite comes out. This guide breaks down what bathroom installations actually cost in the UK in 2026, how each element contributes to the total, and how bathroom fitters can structure quotes that win jobs and protect their margin.

Bathroom Fitting Costs at a Glance (2026)

All-in costs to the customer — covering labour, basic sanitaryware, tiling, and waste disposal — fall into these broad ranges depending on the scope of work:

Job typeTypical total cost
Standard refurb — like-for-like swap, same layout£2,000 – £5,000
Full renovation — new layout, tiling, electrics£5,000 – £12,000
Wet room conversion£4,000 – £10,000
En-suite from scratch£3,500 – £8,000
Downstairs toilet (cloakroom)£1,500 – £3,500

London and the South East typically add 25–40% to these figures. Jobs in Scotland, the North East, and parts of Wales often sit at or below the lower end. These ranges assume mid-range sanitaryware and ceramic tiles — premium suites, natural stone, and underfloor heating push costs significantly higher.

Cost Breakdown by Trade Element

A bathroom renovation draws on four distinct trades, each with its own daily rate and materials cost. Understanding how each element is priced is essential for building a quote that reflects the true cost of delivery.

Sanitaryware

The suite — bath or shower tray, toilet, basin, and taps — is the most visible element and the one where budget range is widest. Entry-level ceramic sets from the major builders' merchants run £300–£600 for a full suite. Mid-range branded sanitaryware (Roca, Ideal Standard, Duravit) sits at £600–£1,200. Designer suites — freestanding baths, wall-hung pans, concealed cisterns — push into the £1,500–£4,000+ bracket and beyond for Italian or German designer brands.

Shower enclosures and trays are additional: a standard 900mm square enclosure with tray runs £150–£500 supply only; a frameless walk-in panel in 8mm glass starts around £400 and can exceed £1,500 for premium models. These numbers are for supply only — fitting is priced within the labour element.

Tiling

Tiling is often underestimated in bathroom quotes. The cost of tiles themselves is only part of the picture:

Tile typeSupply + fit per m²
Budget ceramic (customer-supplied tiles)£20 – £35
Mid-range porcelain, supply and fit£35 – £50
Large-format or natural stone, supply and fit£50 – £80+

A standard bathroom with a tiled shower area and floor typically needs 15–25m² of tiles. Bathroom walls are not always tiled floor-to-ceiling — a half-tile or feature panel design reduces material quantity but increases cutting complexity, which affects labour time. Always quote tiling as a separate line based on actual m² measured on-site.

Plumbing Labour

A qualified plumber or bathroom fitter charges £200–£350 per day in 2026 depending on region and experience. A straightforward like-for-like bathroom swap takes two to three days of plumbing time. A full new layout — moving the soil stack, repositioning the bath, adding a shower — takes four to six days or more. Solo bathroom fitters managing the whole project from strip-out to completion will charge accordingly for their project management time.

Electrical Work

Any electrical work in a bathroom — extracting fans, shaver sockets, heated towel rails, downlights, underfloor heating thermostats — must be carried out or certified by a Part P competent person. Electrical day rates run £150–£300. Most bathroom jobs need half a day to a full day of electrician time for the basics; wet rooms and full renovations with multiple circuits need more. This work must be notified to building control unless carried out by a registered competent person scheme member such as NICEIC or NAPIT.

Flooring

Floor finishes in bathrooms run from £15 per m² (luxury vinyl tile, supply and fit) to £60+ per m² for large-format porcelain or natural stone with full bed and grout. Heated floors require a screed bed or a suitable substrate and add material cost — see the underfloor heating section below.

Budget vs Luxury Suite: What You Get and What It Costs

The difference between a budget and luxury bathroom installation is not just materials — it is specification, finish quality, and complexity of installation. Here is how the two ends of the market compare on a standard family bathroom:

ElementBudgetLuxury
Suite (bath, toilet, basin, taps)£350 – £600£1,500 – £4,000+
Tiles (20m²)£400 – £700£1,000 – £3,000+
Shower enclosure£150 – £300£600 – £2,000+
Vanity unit / storage£100 – £300£500 – £2,000+
Total materials + fit (approx)£2,000 – £3,500£7,000 – £15,000+

The labour cost does not scale linearly with suite cost — a luxury freestanding bath takes longer to fit than a standard pressed-steel model, and large-format tiles take more skill and time to lay than standard 300mm ceramics. Skilled bathroom fitters handling premium projects should price their labour accordingly.

Walk-In Shower vs Bath: Cost and Space Considerations

One of the most common decisions in a bathroom renovation is whether to keep the bath or replace it with a walk-in shower. Both options have cost and practical implications:

  • Retaining a bath with over-bath shower: The cheapest option where a shower is needed. A thermostatic bar shower on the existing bath with a glass screen costs £300–£800 supply and fit. Tiling the bath surround adds £200–£500. Suitable for families who need the bath for young children.
  • Shower tray and enclosure replacing the bath: Frees up floor space in smaller bathrooms. Supply and fit of a 1200x800mm tray, waste, and frameless sliding enclosure typically costs £600–£1,500 before tiling the shower walls. Faster to fit than a wet room and requires no specialist waterproofing.
  • Walk-in wet room conversion: The most expensive shower option — see the wet room section below — but delivers the cleanest finish and greatest accessibility. A linear drain, full floor-to-ceiling tile, and frameless glass panel runs £4,000–£10,000 all-in depending on size and specification.
  • Freestanding bath with separate shower enclosure: The premium split option. Requires sufficient floor space (typically 5m² minimum usable area to feel comfortable). Materials alone for a quality freestanding bath and frameless shower enclosure start at £2,000–£4,000 before any labour or tiling.

From a resale perspective, most estate agents and property surveys suggest a bathroom with at least one bath is preferable for family homes — removing the only bath in a property can affect value. For en-suites and second bathrooms, shower-only is rarely a problem.

Wet Room Conversion Costs and Waterproofing

A wet room is a fully waterproofed, level-access shower room where the entire floor drains to a central or linear drain. The defining cost difference between a wet room and a conventional tiled shower is tanking — the waterproofing layer applied to walls and floor before tiling begins.

Tanking and waterproofing: Adds £300–£800 to the project cost depending on room size and method. Tanking boards (such as Wedi or Schluter Kerdi) are the fastest and most reliable method for first-floor bathrooms, where leaks into the floor below are a critical risk. Liquid applied systems (BAL Tanking Slurry, Mapei Mapelastic) are suitable for ground-floor rooms and solid concrete substrates. Never fit a wet room on a suspended timber floor without specialist advice — the deflection in timber joists causes tanking to crack over time.

Floor former or screed: A wet room floor needs a fall of approximately 1:80 to 1:40 towards the drain to prevent pooling. On concrete, this is achieved with a screed. On timber, a pre-formed wet room former (such as Wedi Fundo or Aqua Level-Fix) is the correct solution — these are tiled over and provide the fall built in. Former costs: £150–£400 supply depending on size.

All-in wet room costs by size:

Wet room sizeTypical all-in cost
Small (under 4m²)£4,000 – £6,000
Medium (4–7m²)£6,000 – £8,500
Large or full wet room conversion£8,500 – £10,000+

Underfloor Heating in Bathrooms

Electric underfloor heating (UFH) is the standard choice for bathrooms — wet (hydronic) systems are rarely cost-effective in a single room. Electric UFH uses a heating mat or cable laid under tiles, connected to a thermostat and controlled independently from the main heating system.

Cost to add electric UFH to a bathroom:

  • Heating mat supply (3–6m²): £80–£200
  • Thermostat (programmable with floor sensor): £60–£200
  • Electrician installation and Part P certification: £150–£400
  • Additional screed or adhesive bed where required: £100–£300

Total addition to project cost: £800–£2,500 depending on floor area, thermostat specification, and whether a dedicated circuit is required. Electric UFH in a bathroom is classified as a notifiable electrical installation — the work must be carried out by a competent person registered with NICEIC, NAPIT, or an equivalent scheme, or be inspected and certified by a building control body.

UFH is one of the more effective upsells in a bathroom renovation — it adds genuine comfort, is reasonable in cost, and is something many customers want but do not think to ask for. Quote it as an optional line on every bathroom project where tiles are being laid.

Ventilation Requirements and Building Regulations

Adequate ventilation in bathrooms is a Building Regulations requirement under Approved Document F. Any new bathroom or significant refurbishment that involves replacing or adding extract ventilation must meet the minimum extract rates:

  • Bathrooms (with or without WC): minimum 15 litres per second intermittent extract
  • Shower rooms and wet rooms: as above, with 15 l/s minimum
  • WC-only rooms: 6 l/s minimum

Where there is no external wall for a direct-duct fan, a continuous mechanical ventilation unit (such as a Nuaire Drimaster or Vent-Axia Lo-Carbon Sense) can extract through the ceiling into the roof void. These cost more to supply and install — budget £200–£500 for the unit plus electrician time.

A standard humidistat-controlled extract fan on an external wall costs £40–£120 supply, plus half a day of electrician time (£80–£150 labour). Always include extract ventilation as a standard line in bathroom quotes — skipping it leaves the customer with a building regulations non-compliance and you with potential liability.

Accreditations: APHC, NICEIC, and Gas Safe

Bathroom installation involves work that is regulated across multiple trades. As a bathroom fitter coordinating a full project, understanding which accreditations apply — and whether you need to bring in sub-trades — is essential:

  • APHC (Association of Plumbing and Heating Contractors): The trade body for plumbing and heating contractors. APHC membership signals professional standing to domestic customers and is relevant when the bathroom involves hot water cylinder work, new pipework runs, or boiler connections. Not a legal requirement, but a strong credibility signal.
  • Gas Safe Register: Required if the bathroom project involves moving or working on the boiler — for example, relocating the boiler from an airing cupboard to make space for the new bathroom layout. Only Gas Safe registered engineers may work on gas appliances. If your project touches the boiler, subcontract this element to a registered engineer.
  • NICEIC or NAPIT: Required for notifiable electrical work in the bathroom — underfloor heating, additional circuits, extract fan installation on a new circuit. A bathroom fitter who is not electrically qualified must use a registered electrician for this element. NICEIC and NAPIT registered contractors self-certify their work without requiring a separate building control inspection.

Managing Multiple Trades: Who Does What and When

A full bathroom renovation typically involves four trades. Getting the sequencing right is the difference between a smooth five-day project and a stop-start two-week disaster:

PhaseTradeTypical days
Strip-out and first fix plumbingPlumber / bathroom fitter1 – 2 days
First fix electrics (fan, lights, UFH cable)Electrician0.5 – 1 day
Wall board, tanking, and prepBathroom fitter / plasterer1 day
Tiling — walls and floorTiler2 – 3 days
Second fix plumbing — fit sanitarywarePlumber / bathroom fitter1 – 2 days
Second fix electrics, testing, certificationElectrician0.5 day
Carpentry (door frame, boxing, shelving)Carpenter0.5 – 1 day

Total for a standard 1-bed or 2-bed family bathroom: 5–10 working days. Wet rooms and full renovations involving a new layout sit at the higher end. Someone needs to coordinate this sequence — that is the bathroom fitter's role when taking on a project as principal contractor. If you are acting as the coordinator, price your project management time explicitly: 10–15% of the total contract value is a defensible project management fee for coordinating multiple trades.

Supply-Only vs Supply-and-Fit

Some customers want to source their own sanitaryware, tiles, and fittings — either because they have found specific items they want, or because they believe it saves money. As a bathroom fitter, this has real implications for your pricing and liability:

  • Customer-supplied sanitaryware: You lose the margin on the goods — typically 20–30% above trade cost. You must compensate by pricing labour at the full rate without any materials discount. More importantly, you take on zero warranty risk for a product that may arrive damaged, be the wrong size, or not fit the space as planned. Always insist on a right-to-refuse clause in your quote: if the supplied goods are unsuitable on arrival, you can quote to source replacements without penalty.
  • Customer-supplied tiles: Tiles bought online without a site measure frequently arrive short — customers do not account for cutting waste (typically 10–15% extra). If you run out of tiles mid-job and the batch is discontinued, the job stalls. Charge a contingency for delayed restarts — or specify that you will source the tiles as part of your quote.
  • Full supply-and-fit: The cleanest arrangement. You control the quality, the lead times, and the spec. Your markup on materials is legitimate profit. Any defect or delivery issue is within your control to resolve. Offer supply-and-fit as your standard proposal; offer a labour-only variant with an explicit premium (labour rates go up, not down, when you are not supplying) to discourage it.

Quoting Guide for Bathroom Fitters

A professional bathroom quote should be itemised by trade element, not presented as a single lump sum. Customers comparing multiple quotes cannot evaluate a single figure — an itemised quote demonstrates competence and makes price comparison meaningless because the scope is explicit.

A complete bathroom quote should include:

  • Strip-out and waste disposal (separately itemised)
  • Sanitaryware — named products with model numbers and finishes
  • Plumbing labour — first fix and second fix separately
  • Tiling — m² quoted with named tile ranges or allowances
  • Electrical works — itemised by circuit/fitting
  • Waterproofing/tanking where applicable
  • Floor finish — type, m², supply and fit or labour only
  • Carpentry — door trims, boxing, shelving
  • Ventilation extract fan — supply and fit
  • Waste and drainage connections
  • Sundry materials and fixings allowance
  • Project management (where coordinating sub-trades)
  • Underfloor heating (as an optional additional line)

List exclusions explicitly: if the quote does not include plastering, painting and decorating, or structural works to the floor substrate, say so. Scope creep on bathroom jobs — the moment you open a wall and find rotted joists — is one of the most common sources of unpaid additional work in the trade. Include a variation clause in your quote: any additional works identified on-site will be quoted separately before being carried out.

Require a deposit before ordering sanitaryware or tiles — typically 25–30% of contract value. Materials on a bathroom job represent a significant outlay before any labour is charged, and a customer who changes their mind after the bath is ordered leaves you holding the cost.
