Cost guide · Updated June 2026
How much does a bathroom renovation cost in West London?
The short answer: complete bathroom renovations start from around £8,000, and most of the projects we deliver across West London land between £10,000 and £20,000. In Kensington & Chelsea a realistic starting point is closer to £10,000–£12,000. Here is what those numbers buy, what moves them, and why two quotes for the same room can differ by thousands.
2026 price bands
What bathroom renovations cost in West London
Real bands from our quotes and current West London market rates — not national averages that fall apart inside the M25.
| Project type | Typical cost | What it covers |
|---|---|---|
| Compact bathroom, simple layout | £8,000 – £12,000 | A smaller room where the layout stays as it is — full strip-out, new sanitaryware, tiling and finishing. |
| Typical complete renovation | £12,000 – £18,000 | Where most of our West London projects land — a full rebuild with quality tiles and fittings, often with layout improvements. |
| Premium, heritage or large rooms | £18,000 – £30,000+ | Natural stone, cast-iron baths, made-to-measure joinery, listed-building considerations or large family bathrooms. |
| Wet rooms | £10,000 – £18,000 | Tanking, floor-forming and drainage make wet rooms start higher — from around £10,000. |
Every price is confirmed in a written quote after a free site visit. The bands reflect typical 2026 market rates in West London, where labour and logistics run well above the UK average.
What the price includes
One team, one price, the whole job
Our quotes cover the complete renovation — not a labour-only figure that grows once materials, permits and waste appear.
The honest part
What actually moves the price
Four factors explain almost every difference between an £8,000 bathroom and a £25,000 one.
Size and layout changes
Keeping the existing layout is the single biggest saving. Moving the soil stack typically adds £1,500–£3,000 before you buy a single tile, because drainage, falls and ventilation all have to be re-engineered.
The finish you choose
Porcelain versus natural stone, standard versus cast-iron baths, off-the-shelf versus made-to-measure joinery. Materials and fittings are where two identical rooms can end up £8,000 apart.
What the strip-out reveals
Most of West London is Victorian or Edwardian housing. Old pipe runs, tired electrics and floors that need reinforcing for a heavy bath are common finds — heritage extras typically add £2,000–£4,000 when they apply. We price the known risks after the site visit, not mid-build.
Borough logistics
Permits are a real cost that varies by borough: a skip licence is around £118 in Hounslow (Chiswick) and £143 in Kensington & Chelsea, where suspending a resident parking bay also costs from £72 per day and needs 10 working days' notice. We build this into the quote upfront.

Cost Questions, Answered
Complete bathroom renovations start from around £8,000, and most of the projects we deliver in West London land between £10,000 and £20,000. Compact rooms with a simple layout sit at £8,000–£12,000, a typical full renovation at £12,000–£18,000, and premium or heritage projects at £18,000–£30,000+. The exact figure is confirmed in a written quote after a site visit.
In the Royal Borough a realistic starting point is closer to £10,000–£12,000. Labour and logistics cost more — a parking bay suspension runs from £72 per day with 10 working days' notice, a skip licence is £143, and mansion blocks often require a licence to alter — and the housing stock leans towards finishes at the upper end of the range.
Yes, noticeably. If the bath, WC and basin stay roughly where they are, you avoid moving the soil stack — which alone typically adds £1,500–£3,000. A good renovation can still transform the room without moving a single waste pipe.
Wet rooms start from around £10,000 and most land between £10,000 and £18,000. The premium over a standard bathroom pays for tanking (waterproofing), forming the floor falls and drainage — work you cannot see in the finished room but cannot skip.
Usually because they price different things. A low quote often assumes the simplest materials, excludes permits and waste, and treats anything found at strip-out as an extra. Our written quote sets out the scope, the assumptions and what happens if the floor or pipework needs work — so the price you agree is the price you pay.
Most complete bathroom renovations take 2 to 4 weeks on site. Wet rooms tend to sit at the longer end because of tanking and floor-forming. Our recent projects in Chiswick, Acton and Northfields each took around 3 weeks.
