How Much to Remodel a Bathroom?
According to InstantCost.co.uk's 2026 UK pricing data, bathroom remodels range from £1,800 for a small cloakroom refresh to £18,000 for a luxury refit, with the national average for a mid-range remodel of a standard family bathroom sitting at £5,500 to £8,500. The single biggest factor separating one end of that range from the other isn't the fittings you choose, it's whether you keep the existing layout or move things around.
Cost by Project Type
Project | Typical UK Cost (2026) | What It Covers |
|---|---|---|
Small cloakroom refresh | £1,800 to £3,000 | Re-tile, new toilet and basin |
Standard bathroom, budget | £3,500 to £5,500 | Like-for-like, basic finishes |
Standard bathroom, mid-range | £5,500 to £8,500 | Most common UK project |
En-suite, small | £3,500 to £6,000 | Compact wet room or shower room |
Full wet room conversion | £6,000 to £12,000 | Tanking and drainage included |
Luxury refit | £9,000 to £18,000 | Premium fittings, underfloor heating |
The mid-range tier at £5,500 to £8,500 is where most UK households land, covering a full replacement of suite, tiling, and finishes in a standard family bathroom without significant structural change.
The Layout Decision That Drives Everything
This is the number worth knowing before anything else: keeping your existing layout avoids £600 to £1,500 in plumbing relocation costs, according to InstantCost's data. Moving a toilet, bath, or shower to a new position means altering waste pipes and supply runs, which is skilled, time-consuming work that adds meaningfully to both the labour bill and the project timeline.
If your current layout works reasonably well and you're primarily updating tired fittings and finishes, staying with it can be the difference between a budget-tier and mid-tier project for essentially the same visual result. If the layout genuinely doesn't work, a bath where you'd rather have a walk-in shower, or a cramped arrangement that wastes floor space, that's a legitimate reason to spend the extra, but it should be a deliberate choice rather than something that creeps in.
Where the Money Actually Goes
Labour typically accounts for 40 to 55% of a bathroom remodel's total cost, which is genuinely higher than most people expect and explains why quotes vary so much between contractors for what looks like the same job. A mid-range remodel typically takes 7 to 12 working days, and it's a job involving multiple trades, plumbing, tiling, electrical, plastering, sometimes coordinated by a single fitter and sometimes booked separately.
The remaining 45 to 60% covers the suite, tiling, flooring, and finishes, which is where your specification choices have the most direct effect on the total.
Optional Extras Worth Budgeting For
Extra | Typical Cost |
|---|---|
Underfloor heating | £500 to £1,200 |
Heated towel rail | £150 to £400 |
Bespoke vanity unit | £600 to £2,500 |
Underfloor heating is worth deciding on early rather than later, since it needs to go in before the floor is tiled. Retrofitting it means taking up a floor you've just paid to have laid.
Regional Variation
London costs 20 to 30% more than the national average across bathroom remodelling work, which on a mid-range project means roughly £6,600 to £11,000 rather than £5,500 to £8,500. This is driven by both higher labour rates and higher overheads for contractors operating in the capital.
Where You Can Genuinely Save
Beyond keeping the existing layout, sourcing your own suite and tiles rather than having the contractor supply everything can reduce costs, though it shifts responsibility for delivery timing and any faulty items onto you. Choosing standard-size tiles in a simple layout rather than large-format or intricate patterns reduces both material waste and labour hours. Keeping the existing bath and replacing only the visible surrounds and fittings is another option where the bath itself is sound.
When a Remodel Isn't Actually Necessary
Worth considering honestly before committing to a full project: sometimes what makes a bathroom feel dated is a small number of specific things rather than the whole room. Tired-looking tiles are a common example, and replacing them is one of the more disruptive and costly elements of any remodel. Painting existing tiles is a genuinely viable alternative in the right circumstances, at a fraction of the cost of retiling.

Common Mistakes and What to Do Instead
Mistake: moving fixtures without a clear reason. Layout changes add £600 to £1,500 in plumbing costs alone. If the current arrangement works, keeping it is the single largest saving available on any bathroom project.
Mistake: underestimating the labour share. At 40 to 55% of total cost, labour is often more than half the bill. Cheap fittings won't rescue a budget if the labour scope is substantial.
Mistake: deciding on underfloor heating after tiling has started. It has to go in before the floor is laid. Retrofitting means lifting a new floor, which is a genuinely avoidable cost.
Mistake: comparing quotes without checking what's included. Some contractors quote labour only, others supply and fit. A quote that looks lower may simply exclude materials.
Mistake: not building in a contingency. Bathroom projects frequently uncover issues once tiles come off and floors come up, hidden damp, rotten flooring, or dated pipework. A 10 to 15% buffer is realistic rather than pessimistic.
Mistake: assuming a full remodel is the only option. Where the layout works and fittings are sound, targeted updates like tile painting, new taps, or resealing can transform a bathroom's appearance for a fraction of a full project's cost.
Timeline
A mid-range bathroom remodel typically takes 7 to 12 working days. That's the on-site work rather than the full project duration, since ordering fittings, arranging trades, and any waiting for materials can extend the calendar timeline considerably beyond the days actually worked. Wet room conversions and projects involving layout changes sit at the longer end, since tanking and pipework alterations both add time.

Getting a Fair Quote
Ask any contractor for a written breakdown separating labour from materials, and confirm specifically whether the price includes removal and disposal of the existing suite, making good after any plumbing alterations, and all necessary electrical work. These are the areas where quotes most commonly differ despite looking comparable on the headline figure. Get three quotes for a project at this value, and be cautious of any figure substantially below the others, since it often reflects a narrower scope rather than better value.
Staying Safe and Compliant
Any electrical work in a bathroom falls under Part P of the Building Regulations and must be carried out by a qualified, registered electrician, this isn't optional and affects both safety and your ability to demonstrate compliance if you sell the property. Confirm your contractor's arrangements for this rather than assuming it's covered. Plumbing alterations connecting to the mains should comply with the Water Supply (Water Fittings) Regulations 1999.
Building Regulations requirements can change and vary in application, so confirm current guidance with your contractor or local authority before work starts, particularly for projects involving layout changes or new electrical circuits.
