How to choose the best bathroom fitters in the UK (2026)
Nobody can hand you a credible national ranking of bathroom fitters — the trade is thousands of small local firms, and any “top ten” list is advertising. What you can do is judge a fitter properly: check the plumbing and electrical registrations, read an itemised quote carefully, and look at recent work. Bathrooms are unforgiving — a badly detailed shower tray leaks into the ceiling below — so this is a job where getting the choice right pays for itself.
- Fitting labour only: around £2,000–£4,000 for a standard bathroom
- Supply and fit: typically £4,500–£12,000
- Non-negotiable: Part P registered electrics and WaterSafe or APHC plumbing

What makes a bathroom fitter good
A bathroom brings together plumbing, electrics, tiling, waterproofing, ventilation, plastering and sometimes carpentry inside the smallest room in the house. The trade that dominates matters. Most bathroom fitters are plumbers who have specialised, which is usually the right background because the plumbing and the waterproofing are where expensive failures happen. Some are tilers who expanded, and produce beautiful finishes but subcontract the services. A few are general builders, which is the right call when you are also moving walls or converting a bedroom into an en suite.
The single most important technical skill is waterproofing detail — tanking behind tiles in a shower zone, getting falls right on a wet room floor, sealing where the tray meets the wall. It is invisible when finished, which is precisely why cheap quotes cut it. Ask any fitter how they will tank the shower area and listen to how specific the answer is.
Accreditations that matter for a bathroom
| Accreditation | Covers | Why it matters |
|---|---|---|
| TrustMark | Government-endorsed vetting | Firms are assessed on technical competence, trading practice and customer service |
| NICEIC or NAPIT | Electrical installation | Bathroom electrics are zoned and notifiable under Part P; a registered electrician can self-certify the work |
| WaterSafe | Plumbing to Water Regulations | An umbrella scheme covering approved plumbing contractors across the UK |
| APHC or CIPHE | Plumbing and heating competence | Trade bodies with membership criteria and codes of practice |
| Gas Safe | Boiler and gas work | Only needed if the job touches the boiler or gas supply — but legally required when it does |
Bathroom electrics are not ordinary electrics
Bathrooms are divided into zones, with rules on what fittings can go where, how they are protected and what earthing and bonding is required. This work is notifiable under Part P of the Building Regulations. Either a registered electrician self-certifies it, or you have to notify building control and pay for an inspection. Make sure the quote says which.
What a bathroom costs in 2026
As with kitchens, be clear whether you are pricing labour only (you buy the suite and tiles) or supply and fit. Here is a realistic 2026 UK picture.
| Job | Typical 2026 UK cost | Notes |
|---|---|---|
| Fitting only — standard bathroom | £2,000 – £4,000 | Like-for-like swap, services staying roughly in place |
| Fitting only — relocated suite | £3,500 – £6,000 | Moving the WC or bath means new waste runs |
| Supply and fit — budget | £4,500 – £7,000 | Entry-level suite, ceramic tiles, basic shower |
| Supply and fit — mid range | £7,000 – £12,000 | Quality suite, porcelain tiles, thermostatic shower, vanity unit |
| Supply and fit — high end | £12,000 – £25,000+ | Premium brassware, large-format or natural stone, bespoke joinery |
| Small en suite | £3,500 – £7,000 | Less material, but the same number of trades |
| Wet room conversion | £6,000 – £15,000 | Full tanking and floor falls push cost and skill requirements up |
Frequent extras: tiling labour at £45–£90 per square metre depending on tile size and pattern, moving a soil pipe at £500–£1,500, electric underfloor heating at £600–£1,500, a new extractor fan at £150–£400, and strip-out plus skip hire at £250–£500.
Comparing quotes like-for-like
Bathroom quotes are unusually easy to misread because so much of the cost is hidden behind the tiles. Send every fitter the same written brief, then check each quote covers:
- Strip-out and disposal — including the old suite and tiles, and skip hire
- Waterproofing — what tanking system, and over what area
- Tile allowance — a price per square metre for supply, and the labour rate separately
- Electrics — named registered electrician, and the certificate you will receive
- Ventilation — extractor specification and where it vents to
- Making good — plastering, ceiling, painting, flooring and door adjustments
- Payment stages and a written start date and duration
If one quote is dramatically lower, look first at the tanking and the tile allowance — that is nearly always where the difference hides. Our bathroom quotes form sends the same specification to several vetted fitters so the comparison is genuinely like-for-like.
Red flags
- No mention of tanking or waterproofing anywhere in the quote.
- “I’ll do the electrics myself” from a plumber with no Part P registration.
- Large cash deposit before any materials have been ordered.
- No extractor in the specification — ventilation is a Building Regulations requirement, not an upgrade.
- Tiling straight onto plasterboard in a shower area without a suitable backer board or tanking system.
- No public liability insurance — a leak into the room below is exactly the scenario it exists for.
Questions to ask before you book
- How will you waterproof the shower area, and what product will you use?
- Who is doing the electrics, and what is their registration number?
- What certificates do I receive at handover?
- How many working days on site, and will the same team be here throughout?
- Will I have a usable WC during the works?
- What workmanship guarantee do you offer, and is it insurance-backed?
How long a bathroom takes
A straightforward like-for-like refit generally runs seven to ten working days. Moving the suite, retiling floor to ceiling, or converting to a wet room pushes it to two to three weeks. The sequence matters: strip out, first-fix plumbing and electrics, plastering and boarding, tanking, tiling, second fix, then sealing and snagging. Tanking and adhesive need curing time, so a fitter who promises a full bathroom in four days is skipping something. If it is your only bathroom, agree up front how many days you will be without a working WC.
FAQs: choosing a bathroom fitter in the UK (2026)
How much does a bathroom fitter cost in 2026?
Fitting labour only is typically £2,000–£4,000 for a standard bathroom and £3,500–£6,000 if the suite is being relocated. A full supply-and-fit bathroom usually lands between £4,500 and £12,000, with high-end schemes and wet rooms running higher.
What accreditations should a bathroom fitter have?
TrustMark for overall vetting, NICEIC or NAPIT for the electrical work, and WaterSafe, APHC or CIPHE on the plumbing side. Gas Safe is needed only if the job touches the boiler or gas supply. Ask who holds each registration, because one person rarely holds them all.
How long does a bathroom installation take?
Around seven to ten working days for a like-for-like refit, and two to three weeks if you are moving the suite, retiling completely or converting to a wet room. Tanking and tile adhesive need curing time, so a much faster promise usually means a step is being skipped.
Do I need Building Regulations approval for a new bathroom?
Replacing a bathroom in the same place does not normally need a full application, but the electrical work is notifiable under Part P and must be certified, and adequate mechanical ventilation is required. Structural changes, a new bathroom in a previously non-bathroom room, or new drainage runs can bring wider requirements.
Do I need a separate plumber and electrician?
Effectively yes, though a good bathroom fitter arranges it for you. Most fitters are plumbers by trade and bring in a registered electrician for the notifiable work. What matters is that the quote names who is doing the electrics and states which certificate you will receive.
