New bathroom cost by room size
These are supply and fit prices for 2026, from Screwfix's published new bathroom cost guide. They include the suite, labour and finishing, and assume the room keeps roughly the same layout.
| Room | Size | What is in it | Typical cost, supplied and fitted |
|---|---|---|---|
| Small or cloakroom | Under 4m² | Two piece: toilet and basin | £3,000 to £5,000 |
| Standard bathroom | 4m² to 8m² | Three piece: bath or shower, toilet, basin | £5,500 to £8,500 |
| Large family bathroom | 6m² to 9m² | Four piece: bath, separate shower, toilet, basin | £7,500 to £11,000 |
| High spec or luxury | Over 9m² | Freestanding bath, walk-in shower, premium finishes | £12,000 to £20,000+ |
Other UK sources land in the same place. Checkatrade puts a low to mid range bathroom, including materials, at £5,500 to £8,000, with an average of about £7,000, and a high end or complex job at £14,000 or more. MyBuilder's average is lower, at about £4,500. It does not say how that figure is worked out, so it may not compare directly with the Screwfix and Checkatrade ranges.

Method: room ranges from Screwfix's 2026 new bathroom cost guide. Moving fittings adds £500 to £1,000 (Screwfix). Underfloor heating adds about £100 per m² (Checkatrade, March 2026). This is an estimate for budgeting; get at least two written quotes before you commit.
Where the money goes
MyBuilder's August 2026 figures break a typical bathroom job down like this:
| Part of the job | Typical cost |
|---|---|
| Suite installation | £600 to £1,500 |
| Plumbing | £800 to £1,200 |
| Tiling | £800 to £1,500 |
| Electrics (lights, fan, shaver point) | £500 to £800 |
| Flooring | £400 to £600 |
| Painting and decorating | £300 to £600 |
| Ripping out the old bathroom (Checkatrade) | £600 to £1,000, plus skip hire |
Day rates from Screwfix's 2026 guide: a plumber charges about £325 to £450 a day and a tiler about £200 to £350 a day. Total labour for a full refit usually comes to £2,000 to £4,000 (MyBuilder).
What the parts cost: a real shower room example
This is a 1200 x 800mm walk-in shower area with a basin and towel rail, priced from the PlumbXtra range at the time of review, including VAT. It shows how the parts side of a budget adds up.
| Item | Product | Price |
|---|---|---|
| Shower tray | DUSC stone resin tray, 1200 x 800mm, 30mm low profile | £210.13 |
| Shower door | DUSC Momentum 1200mm sliding door, chrome, 8mm glass | £277.97 |
| Shower | DUSC Core concealed shower set with riser rail, chrome | £289.94 |
| Wall panels, two shower walls | 3 x Kartell PVC wall panels, 2400 x 1000mm, 10mm | £135.00 |
| Vanity unit and basin | Barcelona white 550mm vanity unit and basin | £99.00 |
| Basin tap | DUSC Core mono basin mixer, chrome | £61.85 |
| Towel rail | Kartell K-Rail 400 x 800mm, matt black | £57.61 |
| Total | Toilet, waste, valves and sundries not included | £1,131.50 |
Delivery is calculated at checkout and varies by item and supplier. Choosing brass or gunmetal brassware or a designer towel rail will raise the total, and you will also need a toilet and plumbing sundries, which Screwfix puts at £300 to £600 for a full bathroom.

- Keep the layout. Moving the toilet or waste can add £500 to £1,000 and up to 30% on labour (Screwfix). Swapping like for like is the single biggest saving.
- Use wall panels instead of tiles. A 2400 x 1000mm Kartell PVC wall panel is £45, which works out at under £19 per m², with no grout to clean. Wall tiling typically costs £800 to £1,500 as a job (MyBuilder).
- Replace the bath with a shower tray. A 1700 x 700mm or 1700 x 800mm tray fits the space a standard bath leaves, and our stone resin trays start at £131.65.
- Buy the parts yourself. If your fitter supplies the parts, the price usually includes a margin on them. Buying the brassware, enclosure and tray direct and paying for labour only keeps you in control of the spec and the price.
- Choose one finish and stick to it. Chrome is usually the cheapest finish across our taps and showers; other finishes usually cost the same or up to about a quarter more, with some items 30% to 40% more, and brushed nickel can be much more.
- Re-use the radiator pipework for a towel rail. A towel rail on the existing radiator tails avoids new pipe runs. Our towel radiators start at £57.61.
- Get at least two written quotes that list the same items, so you are comparing like with like.
Small bathroom ideas that save space and money
- Sliding or bi-fold shower doors need no swing space. Our bi-fold doors start at 700mm wide and our quadrant enclosures at 800 x 800mm.
- A wet room screen instead of a full enclosure makes a small room feel bigger. KVit wet room screens start at 700mm.
- A compact vanity unit hides pipes and adds storage in a 550mm footprint.
- A concealed shower valve keeps the wall clear and is easier to clean than an exposed bar valve.
- Light, large format wall panels in white gloss or marble effect reflect light and have fewer joins than tiles.
- A slim towel rail doubles as the room's heating and fits beside a door or basin.
How long does a new bathroom take?
A standard like for like refit takes 5 to 10 working days (Checkatrade and Screwfix agree). Checkatrade says a smaller renovation can take as little as 2 days, a small budget bathroom 6 to 12 days and a luxury bathroom 9 to 16 days. Expect the room to be out of use for most of that time, so plan for a second toilet or shower if you only have one.
Common questions
How much does a new bathroom cost on average in the UK?
Checkatrade's March 2026 average is about £7,000 for a low to mid range bathroom, including materials and fitting. Screwfix puts a standard three piece bathroom at £5,500 to £8,500. MyBuilder's average is about £4,500.
How much does it cost to fit a bathroom if I supply everything?
Labour for a full bathroom is usually £2,000 to £4,000 (MyBuilder), plus tiling or panelling, electrics and decorating if your fitter does not include them. Plumbers charge about £325 to £450 a day and tilers £200 to £350 a day (Screwfix, 2026).
Is a shower room cheaper than a bathroom?
Often, yes. A shower tray, enclosure and shower valve cost less than a bath with a shower screen, and a shower room is often smaller. The labour is similar, so the saving is mainly on parts and tiling area.
Are wall panels cheaper than tiles?
For most bathrooms, yes. A Kartell 2400 x 1000mm PVC wall panel costs £45, under £19 per m², and goes up in large sheets with no grout. Tiles cost £15 to £50 per m² to buy (Screwfix), before adhesive, grout and a tiler's time.
Do I need building regulations approval for a new bathroom?
In England, a like for like refit usually does not need Building Regulations approval. You may need it for new or altered waste pipes and drainage, a new electrical circuit, a new fuse box, or adding to or changing wiring near the bath or shower. A registered electrician can sign that electrical work off; otherwise, tell building control before you start. Keep or replace any existing extractor fan, and a new bathroom needs one. All gas work must be done by a Gas Safe registered engineer. Rules differ in Scotland and Wales, so if in doubt, ask your installer or local building control.
Do you fit bathrooms?
No. PlumbXtra supplies bathroom products for delivery; we do not install. Most of our customers buy the parts from us and use their own plumber or bathroom fitter.
