Bathroom Installation Cost UK 2026

A complete bathroom installation covers stripping out the old suite, supplying and fitting all new components, plumbing connections, tiling, flooring, and making good. Costs vary enormously depending on the size of the room, the quality of fixtures chosen, and where you live.

Here are typical total project costs (labour plus mid-range fixtures) for 2026:

Bathroom Type	UK Average	London Premium
Small bathroom suite (basic refresh)	£2,500–£4,500	£3,500–£6,500
Standard family bathroom (full refit)	£4,500–£8,000	£6,500–£12,000
Large or luxury bathroom	£8,000–£15,000+	£12,000–£20,000+
En-suite (small)	£3,000–£6,000	£4,500–£9,000
En-suite (standard)	£4,500–£8,500	£6,500–£12,000

These figures include labour and mid-range fixtures but exclude any structural changes (moving walls, altering window positions), specialist ventilation work, or underfloor heating. Supply-only costs (fixtures purchased by you separately) will reduce the labour element but not always by as much as you'd expect.

Understanding the cost of each element helps you see where money goes and where you might save. Typical UK supply-and-fit prices for 2026:

Component	Budget	Mid-range	Premium
Bath (supply and fit)	£400–£700	£700–£1,500	£1,500–£4,000+
Shower enclosure and tray	£600–£1,000	£1,000–£2,500	£2,500–£6,000+
Walk-in / wet room shower	£1,500–£3,000	£3,000–£6,000	£6,000–£12,000+
Toilet (close-coupled)	£200–£400	£400–£800	£800–£2,000+
Basin and pedestal / vanity unit	£200–£400	£400–£900	£900–£3,000+
Tiling (per m²)	£40–£60	£60–£100	£100–£200+
Flooring (vinyl or tile, per m²)	£25–£50	£50–£100	£100–£200+
Heated towel rail	£100–£200	£200–£500	£500–£1,500+

Labour costs for a bathroom installer or plumber fitting these components typically runs at £180–£300 per day depending on region. A full bathroom installation usually takes 5–10 working days depending on scope and complexity.

A comprehensive bathroom installation quote should cover:

• Strip-out: Removing existing bath, basin, toilet, and tiles. Some installers charge this separately as a day rate.
• Plumbing: Connecting new fixtures to existing hot and cold supply pipes and waste connections. Relocating waste or supply pipes costs extra.
• Electrical: Bathroom lighting, shaver sockets, and extractor fans must be installed by a Part P certified electrician — this may or may not be included in the quote.
• Tiling: Many bathroom fitters offer tiling as part of the package, but some subcontract it or leave it to you. Clarify this upfront.
• Flooring: Similarly, bathroom flooring may or may not be included.
• Waste disposal: Removing the old suite and building waste. Some quote this separately.
• Making good: Patching any walls or plasterwork disturbed during installation.

What is rarely included in a standard bathroom installation quote:

• Structural changes (removing walls, adding windows)
• Underfloor heating installation
• Replacing or upgrading pipework outside the bathroom (e.g., to improve pressure)
• Painting or decorating
• Any work uncovered once the walls are opened up (e.g., rotten joists, hidden leaks)

Several variables can shift the cost of your bathroom installation significantly:

Location

Labour rates in London are 30–50% higher than the national average. In rural areas, travel charges can add to costs if you're away from a major centre.

Existing pipework condition

If your existing supply and waste pipes are in good condition and in the right positions, a new bathroom can be fitted relatively straightforwardly. If pipes are corroded, incorrectly positioned, or need rerouting to accommodate a new layout, costs rise quickly.

Room size and access

A compact en-suite is faster to tile and fit than a large family bathroom. Access also matters: a top-floor bathroom with no lift access for materials, or a basement conversion requiring new drainage, adds time and cost.

Moving the layout

Keeping existing fixtures in approximately the same positions is significantly cheaper than moving them. Relocating a toilet, for instance, requires rerouting the soil stack — a specialist job that can add £500–£2,000 to the project.

Quality of fixtures

A basic but solid bathroom suite from a mainstream retailer might cost £800–£1,500 to buy. A designer suite from a premium supplier can easily reach £5,000–£15,000 for fixtures alone. Labour costs don't scale proportionally with fixture cost — fitting a £4,000 bath takes roughly the same time as fitting a £600 one.

Hidden discoveries

Once tiles are removed and walls opened up, problems often emerge: damp, rotten subfloor, inadequate joists, or pipework that needs replacing. Budget a contingency of 10–15% for unexpected discoveries.

Timeline depends heavily on scope:

• Basic en-suite installation (shower, toilet, basin): 3–5 days
• Standard family bathroom (bath, shower, toilet, basin, full tiling): 5–8 days
• Large or luxury bathroom with custom features: 10–15 days or more

These timelines assume the installer works full days and that no major complications arise. Realistically, allow extra time for:

• Drying time between trades (e.g., tilers waiting for adhesive to cure before grouting)
• Delivery delays on bespoke or specialist items
• Additional work uncovered during strip-out

It's common for a bathroom to be out of use for a full week or more during installation. If it's your only bathroom, make sure you and the installer agree on daily working hours and what facilities you'll have access to at the end of each day.

Bathroom quotes are an area where hidden extras can significantly change what you actually pay. Watch out for:

• Labour-only quotes: A very low quote may only cover fitting — not supply of fixtures. Ask explicitly whether the quote includes supply of all components.
• No VAT stated: A VAT-registered installer must add 20% VAT to the total. If a quote doesn't mention VAT, ask whether the price is inclusive or exclusive. A £5,000 quote + VAT is actually £6,000.
• Tiling and flooring excluded: Many bathroom fitters treat these as separate contracts. If your quote doesn't explicitly include tiling, you may be facing additional costs of £600–£3,000 or more for the tiling work alone.
• Electrical excluded: Bathroom electrical work (lighting, shaver points, extractor fans) requires a Part P certified electrician. This is sometimes excluded from installer quotes and can add £300–£800.
• Waste disposal excluded: Removing your old bathroom suite and bagging building waste can add £200–£400 if not included.
• Day rates for unknowns: Some quotes include a clause that any additional work discovered during installation (rotten joists, hidden leaks, etc.) will be charged at a day rate. This is fair — just make sure you know what that day rate is before you start.

The best protection is a detailed written specification covering every element — supply and fit — before work begins.

For a bathroom installation, always get at least three quotes. The range between the cheapest and most expensive can be surprisingly large — £3,000 or more on a mid-range project — and not always for obvious reasons.

When reviewing quotes, ask each installer:

• Does this include all labour, materials, fixtures, tiling, flooring, and waste removal?
• Is VAT included?
• What's your day rate for additional work discovered during the project?
• Who handles the electrical work, and is that included?
• What's your guarantee on labour — and how long?
• Are you WaterSafe registered? (for the plumbing elements)

Look for bathroom fitters who have verifiable reviews, can provide references from recent jobs, and are willing to put the full scope of work in writing before you pay any deposit.
