Bathroom costs are quoted more inconsistently than almost any other home improvement. Search around and you’ll find “average” figures ranging from £4,000 to £16,000 for what sounds like the same job. Neither number is wrong — they’re describing very different work. Here’s what actually drives the difference, and what to budget in 2026.
The Short Answer
It depends far more on scope than on size. A like-for-like replacement in the same layout is a fundamentally different job to stripping back to brick and starting again, and the price reflects that. Broadly, bathrooms fall into three tiers.
| Tier | Typical cost | What you get |
|---|---|---|
| Basic refit | £4,000 – £6,000 | Like-for-like swap. Same layout, no plumbing moved, standard suite, partial retiling. |
| Mid-range | £7,000 – £12,000 | New layout, quality suite, full floor-to-ceiling tiling, new lighting and extraction, some plumbing moved. |
| Premium | £12,000 – £20,000+ | Wet room or walk-in shower, underfloor heating, premium sanitaryware and brassware, bespoke storage, full replumb. |
Typical 2026 market ranges, not a quote. Essex and the South East sit at the higher end — labour in the region runs up to 20% above the national average.
Where Size Fits In
Size matters less than people assume, because much of the cost is in the fittings and the labour to install them rather than the floor area. A small bathroom with a wet room and underfloor heating will comfortably outprice a large one refitted like for like.
| Bathroom size | Typical range |
|---|---|
| Small — around 2m × 2m | £4,250 – £12,000 |
| Medium — around 3m × 3m | £7,000 – £13,000 |
| Large — around 4m × 4m | £9,000 – £16,000 |
The width of those ranges isn’t vagueness — it’s the honest gap between a straightforward refit and a full redesign in the same room.
Labour vs Materials
As a rough split, expect labour to account for around 40–50% of a bathroom project, with materials making up the rest.
- Bathroom fitters typically charge £320–£480 per day
- Labour for a full installation commonly runs £1,500–£3,000
- Plumbing a bathroom averages around £3,250, excluding the sanitaryware itself
Most bathrooms take between five days and three weeks depending on scope. Tiling is usually the longest single stage, and it’s the one where rushing shows.
The Biggest Cost Driver: Moving the Plumbing
If you take one thing from this guide, make it this. Keeping the toilet, basin and bath or shower roughly where they already are is the single most effective way to control a bathroom budget.
Moving a basin a short distance is straightforward. Moving a toilet is not — soil pipes need particular falls to drain properly, which can mean lifting floors, boxing in new runs, or in some cases a pump. A layout change that looks minor on paper can add well over a thousand pounds before anything is tiled.
That doesn’t mean never move anything. It means knowing that moving the toilet is a design decision with a price attached, and deciding deliberately rather than discovering it mid-project.
Costs People Forget
- Removing and disposing of the old suite — including skip hire
- Making good plaster, floors and ceilings once the old bathroom is out
- Electrical work — new lighting, shaver points and extraction all need certifying
- Extraction — a properly specified fan is a building regulations matter, not an optional extra
- Underfloor heating — usually a few hundred pounds in materials, but it affects floor build-up and door clearances
- Water pressure — some showers need a pump or a system upgrade to perform as advertised
- Tile choice — large-format and natural stone take longer to lay, so the labour rises with the material cost
Where the Money Is Best Spent
If the budget is finite, spend it on the things that are expensive or disruptive to change later: the layout, the plumbing, the waterproofing behind the tiles, and the shower valve. Those are buried once the room is finished.
Taps, mirrors, storage and accessories are visible, satisfying and comparatively easy to upgrade in a few years. Being generous with the hidden work and sensible with the visible finishes is almost always the better-wearing decision.
Frequently Asked Questions
How long does a new bathroom take?
A straightforward refit is often five to eight days. A full renovation involving layout changes, replumbing and full tiling more commonly runs two to three weeks.
Can I use the bathroom during the work?
Generally not, once the strip-out begins. If it’s the only bathroom in the house, that’s worth planning around before work starts.
Do I need building regulations approval?
A like-for-like replacement usually doesn’t, but electrical work, new drainage runs and ventilation are all covered by building regulations, and any new electrical circuit needs certifying.
Is it worth converting to a wet room?
Wet rooms suit smaller spaces well and are far more accessible long term, but they demand proper tanking and careful floor falls. Done correctly they last for decades; done cheaply they leak. This is not the place to take the lowest quote.
Should I supply my own suite?
You can, and it sometimes saves money. Be aware that most fitters won’t warrant items they didn’t supply, and that a missing or damaged part becomes your delay rather than theirs.
Getting a Figure for Your Bathroom
Every range here is a market average. What your bathroom costs depends on its condition behind the tiles, whether the layout is changing, and the spec you actually want — which is what a site visit and a written, itemised quote are for.
