Bathroom Fitting Cost UK — What to Charge for Bathroom Installation and How to Price the Job (2026)
Bathroom fitting is one of the most consistent revenue streams in domestic trade work. Unlike a boiler swap or a rewire, which are largely functional jobs, a bathroom renovation is a lifestyle purchase — clients are spending on something they use every day and they want it done properly. That means they will pay for quality, and day rates at the upper end of the range are entirely achievable if you present yourself well and quote correctly.
This guide covers 2026 labour rates for every bathroom type, how long jobs actually take, the full scope of a proper installation, tiling rates, waterproofing costs, and how to structure your quote so you win the right jobs at the right margin.
Bathroom Fitting Labour Rates UK (2026)
The figures below are labour only — sanitary ware, tiles, adhesive, waterproofing membranes, flooring, fixtures and fittings are all separate. Regional variation is significant: expect rates 20–30% higher in London and the South East compared with the Midlands or North.
| Bathroom Type | Labour Only | Typical Duration |
|---|---|---|
| Basic refresh — like-for-like suite swap | £600–£1,200 | 2–3 days |
| Mid-range full bathroom (new suite, tiling, flooring) | £1,500–£3,000 | 5–8 days |
| Premium renovation (wet room, underfloor heating, feature tiling) | £3,000–£6,000+ | 10–14 days |
| En-suite (smaller room, less tiling) | £800–£2,000 | 3–5 days |
| Cloakroom / downstairs WC | £400–£800 | 1–2 days |
Day rates for bathroom fitters in 2026 sit at £220–£350/day in most of England and Wales, rising to £350–£450/day in London and the South East or for fitters working on complex premium projects. A wet room specialist with tiling skills and a waterproofing certification can command the top end of that range. If you are a sole trader doing the full scope — plumbing, tiling, and first and second fix electrics — an effective rate of £300–£400/day is entirely realistic on a well-run job.
Full Scope of a Bathroom Installation
Clients routinely underestimate what goes into a bathroom renovation. A proper full-room fit involves multiple trades working in sequence. Here is every stage of a complete installation:
- Strip out — remove existing suite (WC, basin, bath or shower), disconnect plumbing and cap off supplies, remove existing tiles and floor covering, strip back to bare walls and floor substrate
- Floor preparation — check structural integrity, establish whether floor is solid (concrete) or timber (joists); level substrate with self-levelling compound; confirm deflection is within tile specification limits
- Waterproofing / tanking — apply tanking slurry or sheet membrane to walls and floor, particularly around shower enclosures and wet rooms; brush seal all pipe penetrations, corners and junctions; critical for any shower application
- First fix plumbing — run new supply pipework to WC, basin and bath or shower; position waste runs; fit bath tray or wet room former if applicable; install isolation valves; confirm soil pipe positions and falls
- Electrical first fix — install extractor fan wiring and fused spur, heated towel rail wiring (fused spur from local circuit or new radial), shaver socket, recessed lighting circuits; ensure all cables are in conduit or behind plasterboard before boarding
- Boarding or plastering — fit moisture-resistant plasterboard to stud walls; skim plaster to existing solid walls where needed; allow to cure before tiling (typically 2–4 weeks for plaster, 24 hours for board)
- Wall tiling — set out from centre lines, fix and grout wall tiles; cut around pipes, switches and accessories; apply flexible silicone to all internal corners and junctions with sanitary ware
- Floor tiling or floor covering — fix floor tiles on solid substrate using appropriate flexible adhesive; or lay LVT/sheet vinyl on timber floors; allow full cure time before grouting and fitting sanitary ware
- Sanitary ware installation (second fix plumbing) — hang WC, set bath on feet and secure, install basin and pedestal or vanity unit, fit shower enclosure or glass screen, connect all waste and supply connections, commission and pressure test
- Second fix electrical — fit extractor fan unit and commission, connect heated towel rail, install lighting, fit shaver socket and any additional accessories; test all circuits; issue relevant certificates
- Accessories, mirrors, and finishing — fit toilet roll holders, towel rails, shower screens, mirrors and any bespoke joinery such as vanity units or shaving recesses; seal around bath and basin with sanitary silicone
- Snagging — check all grout lines, silicone beads, drainage falls, flush mechanisms, water pressure at all outlets, extractor operation, towel rail heat; clean down fully and hand over
A like-for-like suite swap skips most of the structural and first fix stages — which is why it can be done in 2–3 days. A full renovation touching walls, floor, electrics and plumbing requires every stage above, and the sequence cannot be rushed without risking problems later.
Waterproofing and Tanking: When to Include It and What It Costs
Waterproofing is non-negotiable in a wet room and strongly advisable around any shower enclosure. A failure here is a claim on your professional indemnity insurance and a very unhappy client whose ceiling below has been damaged. Price it in properly and explain it clearly.
| Scenario | Approach | Material Cost |
|---|---|---|
| Over-bath shower on solid walls | Tanking tape to joints; waterproof tile adhesive and grout | £30–£80 |
| Shower enclosure on plasterboard | Full tanking slurry or Wedi/Schluter board system behind tiles | £80–£200 |
| Full wet room | Continuous tanking membrane to all walls and floor; linear drain; fall in screed | £200–£500 |
For a fixed-price quote, always include waterproofing materials as a named line item. Clients appreciate the transparency and it prevents the conversation where they question why the job took longer than a basic swap. On a day rate, confirm in writing whether waterproofing materials are supplied by you or the client.
Wet rooms add complexity beyond tanking: the floor screed must be formed with a consistent fall to a linear or central drain (typically 1:60 to 1:80 fall), the drain must be correctly located relative to the shower head, and large format tiles on the floor need a suitable uncoupling membrane to manage movement. If you are pricing a wet room for the first time, allow extra time — a poorly graded floor or an incorrectly positioned drain is a significant remedial job.
Tiling Rates: How to Include or Exclude and What to Charge
Tiling is often the most contentious element of a bathroom quote. Some bathroom fitters tile everything themselves; others subcontract it. Either is fine — what matters is that your quote is explicit about what is and is not included, and that the rate you charge (or the sub rate you build in) reflects the actual complexity of the job.
| Tile Type / Complexity | Labour Rate (per m²) | Notes |
|---|---|---|
| Standard ceramic (up to 300×600mm) | £30–£50/m² | Straightforward grid lay; typical bathroom wall tile |
| Mid-range porcelain (600×600mm) | £40–£65/m² | Heavier to handle; more cuts; more waste; use large-format adhesive |
| Large format (600×1200mm+) | £60–£100/m² | Requires back-buttering, suction cups, two-person lift; substrate must be perfect |
| Feature / patterned / mosaic | £70–£120/m² | Complex set-out, high waste factor, slow; price by the day not the m² |
| Floor tile on screeded wet room | £60–£100/m² | Must maintain drainage fall; uncoupling membrane recommended; anti-slip spec required |
Always price adhesive and grout as separate material line items — they are not trivial. A standard 600×600mm floor tile job on a 6m² bathroom floor needs 20–25kg of flexible adhesive and 5–8kg of grout. That is a meaningful cost that should appear in the quote rather than being swallowed silently into your labour rate.
When subcontracting tiling, typical rates from specialist tilers run £150–£250/day. On a full bathroom with 20–25m² of tiles, budget 2–3 days of tiler time. Build this into your fixed price or present it as a transparent line item — either approach works as long as it is in writing.
What Bathroom Fitters Typically Subcontract
Even experienced bathroom fitters subcontract certain elements — either because they lack the qualification, or because it is more efficient to bring in a specialist:
- Plastering — most bathroom fitters do not plaster. After strip-out, damaged walls typically need skimming. Budget £150–£350 for a plasterer to make good a standard bathroom; more if full walls need fresh plaster. Factor this into your quote and either include it or list it as a separate trade the client must arrange.
- Specialist tiling in complex pattern rooms — intricate herringbone, book-matched porcelain, or marble with veining to align requires a specialist. Subbing this out and charging a coordination premium is better than attempting it and producing poor results on a high-spec project.
- Underfloor heating electrical connection (Part P) — electric underfloor heating mats require a new circuit from the consumer unit and must be notified to Building Control under Part P of the Building Regulations. If you are not a registered electrician, sub the connection and notification to a Part P competent person. The UFH mat itself you can install; the electrical connection must be done correctly.
- Structural alterations — if a client wants to move a wall to create an en-suite, or remove a chimney breast to gain space, a structural engineer's input and building regulations approval are required. This is outside your scope; advise the client to arrange it before the bathroom works begin.
When you subcontract, include the sub costs in your quote as named line items and present a single project price. This positions you as the project coordinator, which justifies a higher overall fee and reduces the chance of a client going directly to the subcontractor on the next job.
En-Suite Conversions: Pricing Bedroom-to-Bathroom Work
En-suite conversions — turning part of a bedroom into a new shower room — are increasingly popular and generate solid revenue. The labour involved is more complex than a standard bathroom replacement because you are creating a wet room from a dry space, which means new plumbing runs, new drainage, new electrical circuits, and full waterproofing from scratch.
Labour for a new en-suite conversion typically runs £1,200–£2,500 depending on the distance from existing soil stacks, the floor construction, and whether there is a ceiling height issue (common in loft bedrooms where the eaves slope). A conversion in a first-floor bedroom with a WC stack on the adjacent wall is straightforward; a conversion in a loft room with a long waste run and restricted headroom under the slope is a premium job at the top of that range.
Boxing in services
In an en-suite conversion, supply and waste pipes often need to be routed from elsewhere in the building. This usually means boxing in pipework with timber battens and plasterboard. Allow for this in your material and labour estimate — a 3m pipe box adds half a day and around £50–£100 in materials.
Ceiling height in loft rooms
In a loft conversion, the usable height under the ridge is often only 2.0–2.1m, and drops sharply toward the eaves. A shower enclosure needs a minimum of 2.0m clear height above the tray. Check this on site — a glass enclosure cannot be installed where headroom is insufficient, and the client needs to know before they buy the suite.
Floor construction in upper floors
Timber floors in upper bedrooms are rarely stiff enough for standard floor tiles without additional strengthening. Either fit 18mm ply over the joists before tiling, use an uncoupling membrane such as Ditra, or specify LVT instead of ceramic. Establish the floor specification before quoting — it affects both materials and time.
How to Quote a Bathroom Job Properly
Bathroom quotes go wrong when they are priced from a phone call or a rough description rather than a proper site visit. Here is the correct process:
1. Always visit the site
No exceptions. The bathroom that looks like a simple swap on the phone might have a soil stack running through the middle of the room, a flat roof with no void for waste runs, or an existing shower position that cannot be moved without major structural alteration. You cannot price any of this remotely.
2. Check existing waste positions before demolition
Confirm exactly where the WC soil connection exits — through the floor or through the wall. Confirm the bath and basin waste runs and where they connect to the stack. If the client wants the WC to move across the room, you need to know whether that is possible without lifting the floor screed or boarding — that changes the price significantly.
3. Confirm bath and shower positions before demolition
Get the exact position of the bath or shower tray agreed and confirmed in writing before you start work. Moving a bath that was 'just being swapped in the same position' by 200mm to improve the layout is a legitimate change, but it needs to be instructed and priced as a variation before work starts, not absorbed into your labour at the end.
4. Check floor construction
Establish whether the floor is solid concrete or suspended timber. This determines what tiles can go on it, whether deflection is an issue, and how waste runs can be modified. A concrete floor with a capped floor gully in the wrong position is a breaking-out job; a timber floor with a flexible waste run is straightforward. Price accordingly.
5. Check water pressure
Low mains pressure rules out certain shower valves and thermostatic cartridges. Check the static and dynamic pressure at the cold mains stopcock before specifying a shower. If the client has their heart set on a rain head shower and the pressure is below 1 bar, they need a pump — that is an additional cost and an additional trade element. Surface this on the survey, not after the shower valve is ordered.
Payment Structure and Terms for Bathroom Installations
The standard payment structure for a bathroom installation is straightforward and widely accepted by clients:
50% deposit on signing
Covers materials — sanitary ware, tiles, adhesive, waterproofing, plumbing fittings, electrical materials. On a mid-range bathroom this deposit typically runs £800–£1,500. Do not start work without it. If a client will not pay a deposit, that is a strong signal about payment behaviour on final invoice.
50% on practical completion
Due when the bathroom is fully functional and handed over. Do a walkround with the client, note any snag items and agree a timeframe to fix them — typically 5–10 working days. Do not tie final payment to minor snagging items; agree to return to fix them after payment is received.
On larger premium renovations (£4,000+ labour), a three-stage payment is reasonable: 33% deposit, 33% at first fix completion (before tiling begins), 34% on handover. This reduces your working capital exposure on a two-week job with significant materials costs.
Always issue a written quote before starting work. It should specify what is included, what is excluded (especially plastering if subcontracted separately), the payment schedule, and your approximate programme. This is not bureaucracy — it is protection for both parties and it sets a professional tone that commands confidence.
Track Which Marketing Brings in Your Bathroom Renovation Enquiries
Bathroom jobs are high-value leads. A full bathroom renovation at £1,500–£3,000 labour — or a wet room at £4,000–£6,000+ — is some of the best-margin domestic work available. The difference between landing two bathroom renovations a month and one is material.
Most bathroom fitters spend money on Checkatrade listings, Google ads, Facebook ads, and van signage simultaneously — and have no idea which channel is actually delivering their best enquiries. Not just the most enquiries, but the right enquiries: full bathroom renovations with realistic budgets, not requests to fix a dripping tap or re-seat a toilet.
Trade2Base tracks every enquiry back to its source — every call, every form, every WhatsApp message — so you can see exactly which channel is generating bathroom renovation enquiries versus small plumbing call-outs. When you know that Google Local Services Ads is delivering £2,000-average-value bathroom enquiries and Checkatrade is sending you £150 one-off jobs, you know exactly where to put next month's marketing budget.
