What this covers: fitting and plumbing in baths, basins, showers, toilets and bidets, swapping a suite, shower pressure problems, waste and traps, and leaks and sealing — the water side of a bathroom.
Not a bathroom-plumbing job? A single dripping or seized tap is Tap Repair & Installation; a faulty toilet on its own is Toilet Repairs; a blocked waste is Blocked Drains; water escaping out of sight is Leak Detection; and tiling, plastering or the electrics need a tiler or electrician (more below).
Renting or a council tenant? Bathroom repairs are your landlord’s responsibility; council tenants use the council repairs route. More in the FAQs.

Showers and water pressure — getting the right type
Most bathroom questions come down to the shower, and the right one depends on your water system:
- Mixer shower — blends existing hot and cold, so the flow is only as good as your system’s pressure.
- Electric shower — heats cold mains water on demand, so it works even when hot water or pressure is limited.
- Power shower — has a built-in pump, the usual answer for a low-pressure, gravity-fed system (a cold tank in the loft).
- Thermostatic valve — holds a steady temperature and stops scalding when someone runs a tap elsewhere.
A combi or unvented system usually gives good mains pressure and suits a mixer; an older gravity-fed system often needs a pump or an electric shower. Hard water is the other factor — Thames Water supplies the borough with hard water, and scale clogs shower heads and furs up valves over time.1 One boundary worth knowing: a plumber fits the shower, but wiring the circuit for an electric or power shower is notifiable electrical work under Part P of the Building Regulations — it must be properly certified, usually by a registered competent electrician, or through a third-party certifier or building control.2
Fitting and replacing a bathroom
The plumbing side of a refit is the supply and waste behind the fittings: running and connecting hot and cold, setting traps and falls so everything drains, fitting isolation valves so future repairs are quick, and sealing it all properly. New fittings have to meet the Water Supply (Water Fittings) Regulations 1999, which guard against contamination and backflow — and some, such as a bidet with an ascending spray or flexible hose, must be notified to Thames Water before installation.3 The trades sit either side of the plumber: tiling and plastering are a bathroom fitter’s, and the electrics fall under Part P — notifiable work that a registered competent electrician, a third-party certifier or building control must certify.2 Agree who’s doing what before the job starts, so nothing falls between them.
Leaks and the flat below
In flats and conversions, the bathroom is the room most likely to leak into the home underneath — and it often does so quietly. The usual culprits are failed sealant around a bath or shower tray, a loose waste connection, or an overflowing trap, and the first sign is frequently a stain on the ceiling below rather than anything you’d spot in your own bathroom. Re-sealing on a schedule and sound waste joints are cheap insurance; if water’s clearly escaping but you can’t see from where, that’s Leak Detection.
Find a verified bathroom plumber by district
The systems — and the snags — follow the housing.
West — Muswell Hill, Highgate, Crouch End, Hornsey, Fortis Green, Alexandra Park. Period homes often run gravity-fed systems off a loft tank, so bathroom pressure is low and a pump or power shower is frequently the fix; layouts are tight, soil pipes original, and hard-water scale heaviest.
Centre — Wood Green, Turnpike Lane, Bounds Green, Bowes Park, Noel Park. Flats and conversions, where an upstairs bathroom can leak into the home below before anyone notices — sealing and sound waste joints matter, and access shapes the job.
East — Tottenham, Bruce Grove, Seven Sisters, South Tottenham, West Green, St Ann’s. A dense mix of estates and conversions; council tenants use the council’s repairs route for bathroom repairs rather than a private plumber.5
North-east — Tottenham Hale, Northumberland Park, White Hart Lane, Broadwater Farm. New-build flats usually have combi or unvented systems with good mains pressure, suiting mixer and electric showers; fittings are often concealed or wall-hung, and access can run through a managing agent.
South edge — Harringay/Green Lanes, Finsbury Park, Manor House, Stroud Green. Boundary-sensitive, so confirm you’re in Haringey if you’ll need the council route; the older terraces here share the low-pressure, period-layout quirks.
What bathroom plumbing costs
| Bathroom job (plumbing) | Typical Haringey range (editorial estimate) |
|---|---|
| Fit or replace a basin and tap | £100 – £250 |
| Fit or replace a toilet | £150 – £350 |
| Supply and fit a mixer shower | £150 – £350 |
| Fit an electric shower (plumbing; wiring separate) | £200 – £450 |

| Reseal a bath or shower | £80 – £180 |
| Plumb in a full suite (plumbing only) | £600 – £1,500+ |
Editorial estimate only — broad indicative ranges to sense-check a quote, not regulated rates, not market data and not a published cost survey. These cover the plumbing only — tiling, plastering and electrics are separate trades. Layout changes and access move the figure most; always confirm what’s included first.
A local factor: all of Haringey is inside the London-wide Ultra Low Emission Zone,6 and controlled parking zones can affect where a plumber parks — worth a word when you book (the Congestion Charge doesn’t reach Haringey).
Frequently asked questions
Often a gravity-fed system with a loft tank, where there isn’t much pressure to start with — a pump or power shower usually fixes it.
