How much does a bathroom renovation cost in London in 2026?

A family bathroom renovated by a contractor in London costs about £21,100 to £27,400 including VAT in 2026, at a Standard finish. That is £15,000 to £18,000 of building work before VAT, £18,000 to £21,600 with it, from the bands our free estimate uses, plus £3,100 to £5,800 for the products, including VAT, from our free second fix calculator: the toilet, basin and vanity, bath and shower, taps, towel rail, tiles and tanking.

The building work strips the room out and rebuilds it in the same layout, tanked and tiled, fitting products you supply. Among typical London jobs priced on our estimator in September 2026, a family bathroom renewed in the same layout came to £16,000 to £16,500 before VAT, as our house refurbishment cost guide sets out. At Standard, the free estimate puts a wet room's building work at £15,000 to £17,000 and a cloakroom WC's at £6,000 to £7,000, also before VAT.

With the building work at Standard, a family bathroom comes to, including VAT:

• With Budget products: £19,400 to £24,500
• With Standard products: £21,100 to £27,400
• With Medium products: £23,900 to £32,100
• With High products: £28,500 to £43,900

Each total is the building work with VAT, plus the products. At the ends of the range, the free estimate's Essential finish with Budget products comes to £15,800 to £20,300, and its High finish with High products to £30,300 to £46,300. The two parts overlap a little, as the calculator counts tile adhesive, grout and a tanking kit that a builder's price may include, so the true total sits slightly lower. Every figure is an indicative benchmark, not a quote.

With only Bathrooms ticked, the calculator prices one bathroom with a bath: supply only, including VAT, before delivery, at UK suppliers' prices checked in September 2026, from best case to worst case.

• Budget, £1,400 to £2,900: a close coupled rimless toilet, a vanity unit with a ceramic basin, an acrylic bath with a screen, a bar valve shower and plain white ceramic tiles at £12 to £25 per m².
• Standard, £3,100 to £5,800: a wall hung toilet on a concealed frame, a branded 600 mm vanity, a Kaldewei steel bath, a hansgrohe or Grohe mixer and Spanish or Italian porcelain at £25 to £42 per m².
• Medium, £5,900 to £10,500: a Villeroy & Boch or Duravit rimless toilet on a concealed frame, a statement vanity, a concealed thermostatic shower and large format porcelain at £40 to £80 per m².
• High, £10,500 to £22,300: a designer wall hung toilet with a Geberit Sigma50 plate, a handmade or designer vanity, a heritage or architectural concealed shower, a solid brass or stainless towel rail and limestone, marble or handmade zellige at £70 to £160 per m².

Each buys 27 m² of tiles, for 24 m² of floor and walls plus 12% for cuts, with adhesive, grout, trims and a tanking kit. Neither tool asks the size of the room: a small bathroom needs fewer tiles, so its products cost a little less. A shower in place of the bath moves each range by £500 or less. Not in the figure: tile backer board and sealer, a level shower's drain and former, and the extract fan, priced with the electrics.

Quotes for the same London bathroom can be far apart, for reasons you can check:

• Who does it, and how: our figures are for a contractor stripping the room out and rebuilding it in the same layout. A fitter replacing the suite in the same layout, keeping the pipework, is a different job. Moving the layout is a bigger one, as the toilet has to reach the soil stack.
• The first fix behind the walls: a wall hung toilet hangs from a frame built into the wall, its cistern hidden behind it, and a concealed shower valve is set in the wall. Both go in at first fix, before the walls are boarded and tiled. The wet areas are tanked under the tiles, and a level walk in shower needs a linear drain and a former under the floor.
• Stone and large format tiles: large format porcelain costs £40 to £80 per m² and limestone, marble or zellige £70 to £160, against £12 to £25 for plain ceramic, and their adhesive, grout and trims up to £38 per m² against £5.50 to £9. The free estimate prices its High finish, for richer materials and more detail, a tenth above Standard.
• VAT: a VAT registered contractor adds 20% to the building work, so check each quote's basis.
• Where in London: our building figures are calibrated to inner west London. Prime central projects often price 8 to 25% above them, outer London commonly 10 to 20% below.
• Condition: anything found when the room is opened up, such as asbestos or a structural defect, is priced when it is found.

Not a family bathroom by a London contractor, on our figures. The least the free estimate gives for its building work is £12,000 before VAT, at its Essential finish, and with VAT and Budget products the room comes to £15,800 to £20,300.

• £5,000 buys the products for a Budget bathroom, £1,400 to £2,900 including VAT, or a Standard one at the lower end of its £3,100 to £5,800, before fitting.
• £10,000 covers a cloakroom WC fitted by a contractor with Budget products, £7,700 to £9,300 including VAT, or a family bathroom's products at Medium, £5,900 to £10,500 including VAT, in all but the worst case.

A fitter replacing the suite in the same layout is a different job, which our pricing does not cover. On these figures the building work is the most expensive part of a bathroom: about nine tenths of the total with Budget products, four fifths with Standard and half to two thirds with High.

On the free estimate a wet room is its own kind: a level floor, fully tanked, with a walk in shower. Its building work runs £15,000 to £17,000 before VAT at Standard, and converting a bathroom into one came to around £15,500 among our published typical jobs. A walk in shower on a tray, in a bathroom kept to its layout, is priced as a bathroom.

With a shower in place of the bath, the products come to, including VAT, £1,500 to £2,900 at Budget, £3,000 to £5,400 at Standard, £5,400 to £10,000 at Medium and £10,400 to £21,900 at High. With the building work at Standard, a wet room comes to £21,000 to £25,800 including VAT with Standard products, and £28,400 to £42,300 with High ones, before the linear drain and former, which the calculator does not price yet.

A cloakroom WC, a toilet and a basin often under the stairs, takes £6,000 to £7,000 of building work before VAT at Standard on the free estimate; a new one under the stairs came to around £6,000 among our published typical jobs. The calculator's pack is a compact toilet, a 400 to 500 mm basin or mini vanity, a mixer, a bottle trap and waste, a small mirror and a compact heated towel rail with valves, with 8 m² of tiling and no tanking kit.

With the building work at Standard, a cloakroom WC comes to, including VAT:

• With Budget products, £500 to £900: £7,700 to £9,300
• With Standard products, £1,200 to £2,200: £8,400 to £10,600
• With Medium products, £2,000 to £3,800: £9,200 to £12,200
• With High products, a guide price of £4,200 to £8,600: £11,400 to £17,000

• In a full refurbishment, the free estimate's £1,300 to £1,600 per m² of floor, before VAT at Standard, includes the kitchen and bathrooms, so their building work is not added on top; their products are. In the calculator's typical Victorian terrace, about 100 m² with one bathroom and a cloakroom WC, these come to £4,300 to £7,900 including VAT at Standard, over a fifth of its £18,500 to £35,400 of finishes for a full strip out. Our guides to renovating a Victorian terrace and a flat in London price the whole job, and the kitchen has its own.
• Renewed on their own, the same bathroom and cloakroom take £21,000 to £25,000 of building work before VAT, or £29,500 to £37,900 including VAT with Standard products.
• In a loft conversion, the en suite is priced as part of the loft, as it shapes the structure and the plumbing: see loft conversions with an en suite.

Whatever the job, choose the toilet and the shower before the first fix starts, as the frames, valves and drains are built to suit them. Our guide to the order of a renovation sets out when.

Each came inside a bigger job, so the time given is the whole job's:

• Eton Lane, Belsize Park: new bathrooms in a two bedroom, two bathroom flat, with upgraded wiring and plumbing, new floors and a redesigned kitchen, in three months.
• Ladbroke Grove, Notting Hill: a new top floor for the kitchen and living space and a full high specification refurbishment, with three bedrooms and two bathrooms on the floors below, in five months.
• Woodside, Wimbledon: two flats made into one house, with a loft conversion adding three bedrooms and two bathrooms, in 13 months.
• Ellerby Street, Fulham: the interior design and build of a 450 m² Victorian house, in six months.

As a guide, a bathroom on its own runs over a few weeks, and we confirm a programme in the proposal.

Both tools are free, in our Design Studio:

1. 01For the products, open the second fix calculator, choose the kind of home and when it was built, and set the bathrooms, with any cloakroom WCs under Adjust the details.
2. 02Under The work and the finish, tick Bathrooms only and choose a level. In your schedule, open Details on the Bathrooms row to choose a bath or a shower, and tap its level to see the other three.
3. 03For the building work, start the free estimate, add each bathroom, wet room or cloakroom WC and choose a finish. It asks where to send your range.

Add 20% VAT to the building work, then the products. A price for your own bathroom comes from a quotation once the room has been seen. To have one team design and build it, see our property refurbishments and design and build services.
