Bathroom Fitting Cost in London (2026 Guide)
Updated October 2026 · 7 min read
Bathroom fitting is one of the most trade-intensive projects in a London home. A full renovation typically involves a plumber, a tiler, and — for any electrical work — a registered electrician, in addition to the main bathroom fitter. Getting the sequencing right and making sure all trades are priced into the same contract is where most bathroom projects go wrong.
This guide covers what bathroom fitting costs in London in 2026: typical ranges by project type, why London costs run higher than the national average, what is and is not included in most quotes, and the legal requirements around electrical work that every homeowner should understand before starting work.
Bathroom fitting costs in London (2026)
The figures below are typical UK cost ranges. London rates generally run 25–40% above the national average, so London projects will typically sit at the upper end or above these ranges. Costs cover labour only; sanitaryware, tiles, and fixtures are additional.

Refurb versus full renovation — what is the difference?
A bathroom refurb replaces fittings like-for-like: the bath, toilet, and basin stay in the same positions; existing soil pipe and waste locations are reused; and walls are tiled over the existing layout. This is the cheapest option because it avoids any structural or plumbing rerouting work.
A full renovation changes the layout — moving the bath to a different wall, replacing a bath with a walk-in shower, converting to a wet room, or changing where the toilet sits. All of these involve moving the soil stack or waste runs, which requires a plumber, additional time, and potentially access to floors or walls. The cost difference between a refurb and a layout change can be significant; clarify which type you are pricing before comparing quotes.
The electrical requirement you must know
Most electrical work in bathrooms — new circuits, new points and work near the bath or shower — is notifiable under Part P. The simplest way to comply is to use a registered electrician, who self-certifies the work.
It applies to adding a shaver socket, moving a light fitting, fitting a heated towel rail with a fused spur, or wiring an electric shower. Work done by an unregistered person is potentially unsafe, will need separate Building Control sign-off, and will be flagged as non-compliant when you sell the property.
When getting a bathroom quote, always ask whether an electrician is included and, if so, whether they are Part P registered. If your fitter is handling the electrical work themselves without mentioning certification, ask to see their registration before work starts.
Budget for electrical work as a separate line in the quote. For a standard bathroom refurb, electrical work is typically a small proportion of the overall cost — but it needs to be done by the right person and cannot be skipped.
What affects the cost of bathroom fitting in London
1. Whether the layout stays the same
Keeping the soil stack, waste, and supply connections in their existing positions is the single biggest cost saving available in a bathroom project. Moving the toilet to a different wall, for example, involves rerouting the soil pipe — which may require access to the floor, walls, or the space below (in a flat or terrace, this can mean involving your neighbours). If the budget is the primary concern, work with the existing layout.
2. Waterproofing specification
All wet areas in a bathroom need to be properly waterproofed before tiling. The quality of the waterproofing system — paint-on versus tanking membrane — significantly affects both the upfront cost and the long-term durability. A paint-on product costs much less; a Schlüter Kerdi or Mapei Mapelastic membrane system is used in commercial wet rooms and carries a significantly lower failure rate. If a fitter does not mention waterproofing in the quote, ask about it.
3. Tile format and coverage
Tile size, format, and the proportion of the room being tiled all affect fitting time. Standard 300×300mm or 600×300mm tiles are fast to lay. Large-format 900×600mm or 1200×600mm tiles require a flatter substrate, more adhesive, and greater precision — each one takes longer to set and align. A fully tiled room costs more to tile than a half-height tile scheme with painted plaster above.
4. Premium fittings and concealed systems
Concealed cisterns, wall-hung pans, frameless shower enclosures, and underfloor heating all add fitting complexity beyond a standard bathroom. Wall-hung WCs require a support frame built into the wall, which needs structural consideration. Underfloor heating requires the correct floor build-up and a separate electrical connection. These are all worthwhile choices, but they should be priced explicitly — not assumed to be included in a standard bathroom fitting quote.
5. Access in London properties
Bathroom projects in London flats, Georgian townhouses, and properties without direct vehicle access all carry additional cost. Skip hire in central London boroughs is expensive; carrying materials up four flights of stairs without a lift adds time. Parking permits, congestion charges, and restricted delivery windows all affect logistics. A good fitter will factor these in at the survey stage rather than presenting them as extras after the job starts.
How to keep bathroom fitting costs down
- Keep plumbing in the same positions. Avoid moving the toilet, bath, or basin to a new wall. The cost of rerouting soil pipes and waste runs adds significantly to a bathroom project, and it is the easiest saving to make at the planning stage.
- Use standard tile formats. 300×300mm or 600×300mm tiles are the fastest formats to lay. Large-format tiles look impressive but cost more to fit, require a flatter substrate, and break more easily on delivery — all of which adds cost.
- Supply your own sanitaryware from a trade supplier. Bathroom trade showrooms and online trade accounts offer significantly better prices than retail. Check the fitter is willing to work with your choice and ask to see the technical specification before ordering.
- Agree the electrical scope at survey stage. Finding out mid-project that an additional electrician visit is needed — or that the existing fused spur needs upgrading — adds cost and delay. A good fitter will identify all electrical requirements at the survey and include them in the written quote.
- Choose a surface-mounted cistern over a concealed one. A concealed cistern requires a frame built into the wall and additional tiling work. A surface-mounted cistern is faster to install and easier to service. If the aesthetic is less important than the budget, it is a meaningful saving.
Frequently asked questions
How long does a bathroom renovation take in London?
A standard family bathroom is typically out of full use for 5–7 working days. An en-suite or cloakroom may take less. A full renovation involving a new layout, moving the soil stack, or fitting a wet room will take longer. Your fitter should give you a day-by-day programme before work starts so you can plan around it.
Why does bathroom fitting cost more in London?
Labour rates in London run higher than the national average — typically 25–40% above. Beyond wages, London adds cost through parking restrictions and van access issues, skip hire charges (expensive in many boroughs), waste removal from flats, and the difficulty of delivering bulky materials such as baths and shower enclosures to upper floors without a lift.
Do I legally need a registered electrician for bathroom electrical work?
Most electrical work in bathrooms — new circuits, new points and work near the bath or shower — is notifiable under Part P. The simplest way to comply is to use a registered electrician, who self-certifies the work. Work done by an unregistered person is potentially unsafe, will need separate Building Control sign-off, and is likely to be flagged as non-compliant at the point of sale.
Can I supply my own sanitaryware to reduce the cost?
Yes — most fitters will work with sanitaryware you have purchased. You will need to supply the full technical specification before the survey so the fitter can plan waste routing, supply connections, and any structural requirements. Make sure the fitter reviews the spec before quoting; some products are significantly harder to install than others, and the fitting cost should reflect this.
What is the difference between a bathroom refurb and a full renovation?
A refurb replaces like-for-like: same layout, same positions for the bath, toilet, and basin. A renovation changes the layout — moving the soil stack, plumbing, or wall positions. Refurbs are significantly cheaper because no structural or plumbing rerouting is required. The cost difference between a refurb and a full renovation can be substantial; always clarify which type you are pricing before comparing quotes.
