Bathroom Renovation Cost in West London: 2026 Price Guide
Most bathroom renovations in West London land between £6,000 and £12,000 in 2026. A small like for like refit starts around £4,500. A larger family bathroom with a new layout and a decent spec runs £12,000 to £18,000. The single biggest cost driver is not the tiles or the suite. It is whether the plumbing moves.
What a bathroom actually costs in West London
These are the ranges we quote across Hillingdon, Ealing, Hounslow and the surrounding areas. They include labour, materials and waste removal, and they assume a working bathroom at the end, not a shell.
| Type of job | What it covers | Typical range |
|---|---|---|
| Like for like refit, small bathroom | Same layout, new suite, new tiling, new flooring | £4,500 to £7,000 |
| Mid range family bathroom | Same layout, better spec, full re tile, new lighting and extraction | £7,000 to £12,000 |
| Bathroom with a layout change | Moving the WC, bath or basin, so new pipework and often a new soil connection | £10,000 to £16,000 |
| En suite, compact | Shower, WC, basin, usually squeezed into an existing room or loft | £4,000 to £8,000 |
| Wet room, level access | Tanking, former, drainage falls, full waterproofing | £7,000 to £13,000 |
| High spec family bathroom | Premium sanitaryware, stone or large format tiling, underfloor heating | £15,000 to £25,000 |
For comparison, the Federation of Master Builders puts a typical UK bathroom renovation lower than these figures. That gap is real and it is mostly London labour rates, parking and access, and the age of the housing stock around here.
Where the money actually goes
People assume the suite is the big number. It usually is not. On a mid range job the labour and the hidden trades take more than half the budget.
| Element | Share of a mid range job | Notes |
|---|---|---|
| Strip out and waste | 5 to 8 percent | Skip or grab hire, and getting it out of a terrace with no side access |
| Sanitaryware and brassware | 15 to 25 percent | The one line you control completely |
| Tiles, materials | 10 to 15 percent | Large format and natural stone cost more to buy and far more to fit |
| Tiling labour | 12 to 18 percent | Pattern, size and how square the room is all change this |
| Plumbing labour | 12 to 18 percent | Rises sharply the moment anything moves |
| Electrics and extraction | 6 to 10 percent | Zoned lighting, shaver point, a decent extractor that meets Part F |
| Waterproofing and screed | 5 to 8 percent | Skimped on more often than any other item |
| Plastering and making good | 6 to 10 percent | Ceilings and reveals after the old stuff comes out |
The thing that really moves the price: moving the pipework
Keeping the WC, bath and basin where they are is the difference between a straightforward week and a much bigger job. The WC is the worst offender. It needs a fall to the soil stack, so moving it can mean lifting floors, boxing in new runs, or in a flat, negotiating a route that does not cross a neighbour’s ceiling.
If you are considering a new layout, get the plumbing route agreed before you fall in love with a design. We have seen plenty of drawings that work beautifully on paper and cannot be drained.
You might not have to pay VAT at all
This is the part almost nobody mentions, and it is worth thousands.
If bathroom work is needed because of someone’s disability, and it is their own private home, the work can be zero rated for VAT. Not reduced. Zero. That covers adapting or extending a bathroom, washroom or lavatory where the changes are necessary for that person, and it can cover putting back space lost to make the adaptation work. Converting a bath to a level access wet room is the common example.
The rules are set out by HMRC, you sign an eligibility declaration, and you do not need to be registered disabled. On a £10,000 job that is £2,000 that never leaves your account. Ask any builder quoting you whether they handle zero rated work, because plenty simply add VAT to everything out of habit.
How long it takes
- Like for like refit: 7 to 10 working days.
- Layout change: 2 to 3 weeks, because first fix, tanking and screed all need drying time.
- Wet room: 2 to 3 weeks, and the tanking is not a stage you rush.
- Compact en suite: 5 to 8 working days if the services are already nearby.
The honest version: a bathroom is a small room with every trade in it. Plumber, electrician, tiler, plasterer and often a carpenter all need their turn, and several cannot overlap. That sequencing, not the size of the room, sets the timeline.
Where budgets slip
- Choosing the tile after the quote. Herringbone, large format and natural stone all take longer to fit. The tile changes the labour, not just the material.
- Finding out what is behind the old tiles. In 1930s West London stock that often means rotten timber, old lead runs or a wall that is nowhere near flat.
- Underfloor heating decided late. It affects floor build up, which affects the door, which affects the flooring.
- Extraction ignored. A weak fan grows mould that ruins a new bathroom in two winters.
- Waterproofing treated as optional. The cheapest line to cut and the most expensive to put right.

Do you need building control?
Usually not for a straight replacement. You do need it if you are adding a bathroom where there was not one, altering drainage, or doing structural work such as removing a wall. New electrics in a bathroom are notifiable either way, so the electrician must certify the work. Our guide to Building Regulations in West London explains what gets inspected and what the council charges.
If the bathroom is part of a bigger project, the loft conversion cost guide and the kitchen renovation cost guide use the same format.
