Bathroom renovation cost in London
How much does a bathroom renovation really cost in London?
A London bathroom renovation typically costs between £3,900 and £21,700, depending on room size and finish level. Most homeowners land somewhere in the middle of that range — the two ends represent a standard-finish WC refit at one end and a large, premium-finish room with a full reconfiguration at the other.
Cost by room size and finish level
These ranges are Maycor's standard estimate bands, rounded to the nearest £100. They assume no major layout changes and easy access — the section below on what pushes the price up explains what moves a job toward the top of its range.
| Room size | Standard finish | Mid-range finish | Premium finish |
|---|---|---|---|
| WC / Cloakroomtoilet & basin only | £3,900 – £5,900 | £4,900 – £7,400 | £5,500 – £8,300 |
| Very small bathroom2–3 sqm | £5,400 – £8,200 | £6,800 – £10,300 | £7,600 – £11,500 |
| Small bathroom3–5 sqm | £5,800 – £9,100 | £7,300 – £11,400 | £8,100 – £12,700 |
| Medium bathroom5–8 sqm | £7,400 – £11,800 | £9,300 – £14,800 | £10,400 – £16,500 |
| Large bathroom8+ sqm | £9,600 – £15,500 | £12,000 – £19,400 | £13,400 – £21,700 |
Mid-range finish runs roughly 25% above standard, and premium roughly 40% above standard — better tiles, sanitaryware and fittings, not a different scope of work. For your exact range, based on your actual room and choices, use the estimate calculator.
What's included at these prices
A Maycor renovation is coordinated by one team from strip-out to finish: plumbing, electrics, waterproofing, tiling, decorating, fittings and waste removal. You are not managing separate trades or gaps between them.
What pushes the price up (or keeps it down)
Room size and finish level set the base range. Everything below is what moves a specific job within — or beyond — that range.
Access difficulty
Easy street-level access costs less to work with than a top-floor flat with no lift, narrow stairs, or restricted parking for skips and deliveries — every extra hour of carrying materials and waste in and out adds labour time.
How much the layout is changing
Keeping the bath, basin and toilet where they already are is the cheapest option. Moving any of them — even by a metre — means moving supply and waste pipework, which is where light, moderate and full-reconfiguration jobs start to separate in price.
Structural changes
Only relevant if a wall is coming down, a floor needs strengthening, or an opening is being altered. Most renovations need none of this, but period properties occasionally do.
What has to come out first
Nothing to remove, a partial strip-out, or a full remove-and-dispose of an old suite all take different amounts of time before the new room can even start going in.
Shower type
An exposed mixer over the bath is the simplest option. A concealed in-wall mixer with an overhead head costs more in labour to chase and box in. A walk-in wet room — full tanking, a pump if the fall to waste needs help — is the most involved and the biggest single jump in the suite.
Heating
A standard towel rail is the baseline. Underfloor heating and designer heated towel rails add both materials and installation labour.
Electrics scope
Ranges from minimal changes (reusing existing circuits) to a full rewire with new lighting, shaver sockets and extraction — the more that changes, the more first-fix and testing time it needs.
Tiling coverage and pattern
Tiling to the ceiling in wet zones costs more than a half-height splashback. Mosaics, herringbone, and large-format patterns take longer to set out and cut than a straightforward brick-bond layout in a standard size tile.
How the estimate becomes a fixed quote
The range above is there to keep the first conversation realistic. A fixed quote follows once the room and site conditions are checked — access, existing pipe runs, and any structural work confirmed in person rather than estimated from a calculator.
Frequently asked questions
Is the price range the final quote?
No — it's there to keep the first conversation realistic. A fixed quote follows a site visit, once room dimensions and access are confirmed.
Why is there such a wide range for the same room size?
The low end assumes a standard finish with no layout changes and easy access. The high end assumes premium fittings, a full reconfiguration, or a difficult-access property. Most jobs land somewhere between the two, not at either extreme.
