Bathroom Installation in West Kensington, London
A new bathroom is a project with a start, a middle and an end, and the middle is where homeowners lose track of who is responsible for what. [The Trusted Plumber West Kensington](/) answers on 07460 069834, matches an independently owned partner company for the plumbing side of the job, and remains the one number that stays on it from the first quote to the last snag.
Published 2026 figures give a sense of scale. A fully fitted UK bathroom commonly costs £4,500 to £11,000, with £6,000 to £8,000 typical for mid-range work, and London runs higher. One London contractor's page puts standard specification at £8,000 to £12,000, which is best read as an upper marker. Plumbing labour alone is often quoted at £500 to £1,200, and a Greater London installer's day rate sits around £300 to £350.
In W14 the bathroom is usually inside a building that someone else also cares about. A Victorian terrace converted to flats shares a stack and floor joists with the flat below. A mansion block off Queen's Club Gardens may need the freeholder's written consent before pipework or the waste is moved. Some roads sit in the Barons Court, Queen's Club Gardens or Gunter Estate conservation areas, where external changes such as a new extractor or soil vent are restricted.
We do not sell tiles, suites or design, and we say so plainly. The partner company covers the plumbing, first-fix and second-fix, the connections to hot, cold and waste, and the water-tightness that decides whether the room lasts.
Ring with the room's size, the building type and what you want changed, and a written quote follows after a visit.

What We Do
Where the Plumbing Work Sits
A bathroom job breaks down into stages, and the plumbing comes in twice.
Strip-Out and First Fix
The old suite comes out, pipework is checked or replaced, and new hot, cold and waste runs go in before walls are boarded. In a Victorian conversion, the partner company checks the floor structure and stack position now, because moving a toilet far from its soil pipe affects the fall of the waste.
Second Fix and Connections
After tiling and decorating, taps, bath, basin, WC and shower are fitted and connected. Fittings carry WRAS approval and installation follows the Water Supply (Water Fittings) Regulations 1999 and BS EN 806. Isolating valves on each supply let you shut off a tap without losing the whole flat.
Showers, Pressure and Hot Water
Combi pressure, a tank-fed system and a mixer shower behave differently. The partner company tests flow before choosing a shower and, if an unvented cylinder is involved, follows Building Regulations Part G3. Hard Thames Water means descaling access matters on showerheads and thermostatic valves.
The Benefits
How We Keep a Bathroom Job Accountable
Projects drift when nobody owns the plan.
Quote From a Visit
The partner company looks at the room, access and floor first. The written quote names what is included, what is excluded and what happens if the floor needs repairs.
Stages, Not Surprises
Plumbing is split into first fix and second fix, with a payment point at each, agreed in writing. Money goes to the partner company, never to us.
One Number for Snags
A drip, a loose fitting or a thermostatic valve that runs warm gets reported to us, and we chase the partner company until it is dealt with.

Why Us
Bathrooms Across W14 and W6
The same room needs different plumbing in different buildings.
Converted Terraces
Waste from a first-floor flat must reach a shared stack without a poor fall. The partner company confirms this before ordering a suite, so the layout is practical, not just attractive.
Mansion Blocks
Fitzgeorge Avenue and Avonmore Road blocks often have rules about working hours, deliveries and shutting down communal water. Tell us about them early so the schedule holds.
Brook Green Townhouses
Victorian townhouses near Brook Green, many split into flats, have old lead-era pipework in places and tight stairs. The partner company plans delivery and pipe replacement before the strip-out.
If a bathroom problem is urgent, see emergency plumbing. If the boiler or radiators are part of the same refurbishment, boiler installation and toilet repair cover those sides. All services are listed on our services page.
What We Mean by Bathroom Installation
We coordinate the plumbing of a bathroom: supplies, waste, fittings, shower connections, heated towel rails and testing. The visible parts, such as tiles, units and decoration, belong to whoever is managing the refurbishment, and we say so at the outset.
The Order of Work
Plumbing happens twice. First fix puts pipes in before walls close, and second fix connects fittings after tiling. A pressure test between the two is the surest protection against a leak in a sealed wall, which is also where a missed leak costs most.
Planning for Flats and Old Buildings
Most W14 bathrooms are inside someone else's building. Floors are timber, stacks are shared and lifts or stairs limit what can be carried in. Planning delivery, bin removal and noise hours is part of the plumbing schedule, not an afterthought.
Access and Parking
Permit bays fill early on streets near North End Road, and Olympia event days affect Hammersmith Road. Tell us the access position when you book and we pass it on so the partner company can plan deliveries and unloading.
Wet Rooms, Waterproofing and Ventilation
Where Plumbing Ends and Waterproofing Begins
A shower tray waste, a bath overflow and a basin trap are plumbing. The membrane behind tiles and the sealant around a screen are waterproofing, and a failure there causes the damp patch on the ceiling below. We ask who is responsible for waterproofing when you book, so the plumbing quote does not quietly assume a task nobody has been given.
Extractor Fans and Soil Vents
Bathrooms need ventilation, and in many W14 flats the extractor and soil vent exit the building on an external wall. In a conservation area, that outlet may be restricted, and the choice of position can change the layout. Check early, because a late discovery is expensive.
Heated Towel Rails
A towel rail fed from the central heating works only while the heating is on. An electric rail works all year, but it is an electrician's job to connect. The partner company explains which applies and what it will, and will not, fit.
Snagging and Handover
At handover, run every tap, flush every toilet and fill the bath and shower while someone checks underneath. Any drip or slow drain gets reported to us the same day, and we chase the partner company so it is dealt with while the job is still fresh.
Before You Ring
Have the room's rough size to hand, the floor you are on, whether the building is a house, converted terrace or mansion block, and a photo of the existing pipework if you can take one. Tell us if the lease requires consent. With that, the first conversation moves quickly to booking a visit rather than collecting basics.
Frequently Asked Questions
How much does a bathroom installation cost in West Kensington?
Published 2026 figures put a fully fitted UK bathroom at about £4,500 to £11,000, with £6,000 to £8,000 typical for mid-range work and London generally higher. One London contractor puts standard specification at £8,000 to £12,000. These are market ranges, not our prices, and the partner company quotes in writing after seeing the room.
Do you supply tiles and suites?
No. We coordinate the plumbing side through an independently owned partner company: pipework, waste, connections and testing. You choose and buy the suite and tiles, or arrange them through whoever is doing the wider refurbishment. The partner company will tell you what it needs to know about fittings before it orders anything. Tell us early if the supplier is delivering fittings, because the plumbing visit should be timed around what has actually arrived.
Do I need permission to alter a bathroom in a mansion block?
Often yes. Leaseholders usually need the freeholder's or managing agent's written consent before moving pipework, waste or extractor outlets, and many blocks restrict working hours and require notice before water is shut off. Check your lease before booking. The partner company can supply a written description of the work to support your request. Allow time for the answer, since managing agents can take a while to reply and a date set too early may have to move.
Will conservation area rules affect a bathroom?
Inside the room, rarely. Outside, they can matter for extractor terminals, soil vent pipes and visible pipework, particularly in Barons Court, Queen's Club Gardens and the Gunter Estate. The partner company asks the council before fixing an external outlet. See our Barons Court page for the local picture. Olympia and Kensington can sit under a different council from the Hammersmith and Fulham side, so confirm the borough per address first.
Can the toilet be moved?
Sometimes. The waste has to keep a workable fall to the soil stack, so moving a toilet a long way across a floor may need a raised platform or a different pipe route. In a converted terrace the stack may sit on a shared wall. The partner company checks this before the layout is agreed.
What standards does the plumbing follow?
Supply pipework follows BS EN 806 and the Water Supply (Water Fittings) Regulations 1999, with WRAS-approved fittings. Waste follows Building Regulations Part H, and hot water arrangements follow Part G, including G3 for unvented cylinders. Ask for the details in the written quote and for a pressure test before the walls are closed. A pressure test record, kept with your quote and receipts, is useful evidence if a joint is ever questioned.
How long does a bathroom installation take?
A straightforward replacement in the same layout may take a week or so overall, though plumbing is only part of that. Moving fittings, replacing joists or waiting for tiling can add time. The partner company gives its plumbing schedule in the written quote, and we do not promise start times we cannot back. A week is only a rough guide, and a larger room or a hidden problem under the floor will stretch it, so allow slack.
How do payments work on a bathroom job?
The partner company that does the plumbing quotes, invoices and takes payment directly, in stages agreed in writing. We handle no invoices or payments. Avoid paying the whole price upfront for work not yet started, and keep every receipt, quote and test record in one place for later. Keep a copy of every stage payment and what it covered, which makes snagging conversations straightforward later.
What happens if there is a leak after the bathroom is finished?
Ring us on 07460 069834 straight away. We pass the problem to the partner company that fitted the room and chase it. Turn off the isolating valve for the fitting concerned, or the stopcock if you cannot find it. Our leak detection and repair page covers hidden leaks. Photographs of the leak and the location help the partner company, and your managing agent will want them too.
Can you convert a bath to a walk-in shower?
Yes, and it is one of the commonest changes. The partner company handles the shower valve, tray waste and water supply, and you or your builder arrange waterproofing and screens. A tray needs a waste with the right fall, so floor height and the stack position are checked first. A pressure check decides whether a pump is needed.
Does hard water affect new bathroom fittings?
Yes. Thames Water's supply is hard, 266 mg/l in its 2025 City-zone report, so limescale marks taps, clogs showerheads and shortens the life of thermostatic cartridges. Choosing fittings with removable filters or easy-descale heads helps. A water treatment device can also be quoted if you want one. Easy-descale showerheads and accessible filters are worth asking about at the quote stage, when the cost is small.
How soon can the first visit happen?
We cannot promise a day, but the line is open at every hour and we match the partner company that can visit soonest in W14 and suits a bathroom project. It sends its name by text first. If the matter is a leak rather than a refit, see emergency plumbing. Give us the postcode and say whether it is a refit or a repair, and the match follows quickly.
