What does a bathroom remodel cost in London?
There's no single answer, but most projects fall into one of three brackets. Knowing which one fits your plans is the fastest way to set a sensible bathroom remodel budget before you start getting quotes. London prices tend to sit at the higher end of the national average, mainly because labour and parking or access costs are higher in the capital than elsewhere in the UK.
Like-for-like replacement of the suite, tiling and basic fixtures. No layout changes and no structural work.
New suite, full retiling, new flooring, updated lighting and some layout changes. The most popular budget range.
Full redesign, high-end fixtures, underfloor heating, a walk-in shower and full waterproofing throughout.

What affects your bathroom remodel budget?
Two bathrooms of the same size can cost very different amounts. These are the main factors that push a bathroom renovation cost up or down:
- Size of the bathroom
- Whether the layout is changing — moving plumbing is expensive
- Quality of fixtures and tiles chosen
- Whether there is damp or structural damage to fix first
- Whether it includes an en-suite or wet room
- Labour costs
💡 Tip: Moving the toilet, basin or bath even a short distance means new pipework — often the single biggest hidden cost in a bathroom refurb. Keeping the existing layout is the easiest way to protect your budget.
What's typically included in a bathroom remodel?
A proper bathroom refurb is more than swapping a few fittings. A typical project covers:
- Strip out and removal of the old suite
- Waterproofing and tanking
- New bath or shower tray installation
- Tiling — walls and floor
- New toilet, basin and taps
- Lighting installation
- Flooring
- Finishing and sealing
If your home needs more than one room updated, it's often more cost-effective to bundle the work into a full house refurbishment or pair it with a kitchen refurbishment while the trades are already on site.
Hidden costs to watch out for
The quoted price isn't always the final price. Ask about these before you sign, because they're the surprises that blow a budget:
- Materials, unless they're clearly agreed in the quote
- Skip hire and waste removal
- Replastering if walls are in poor condition
- Boiler or hot water system upgrades
- Structural repairs discovered during strip out
How to set a realistic bathroom remodel budget
Once you know roughly which bracket you're in, these five steps keep your bathroom remodel budget honest and under control:
- Get at least 2–3 quotes before committing.
- Add 10–15% contingency for unexpected issues.
- Agree all material costs upfront in the quote.
- Ask whether the quote is a fixed price or an estimate.
- For projects over £5,000, ask for a staged payment schedule.
🎯 Honest advice: The cheapest quote rarely ends up being the cheapest job. A clear, itemised quote from an experienced team is worth far more than a vague low number. The same goes for smaller jobs — our handyman services follow the same fixed-price, no-surprises approach.
It's the same principle that applies to any house renovation: plan properly, price honestly, and leave a little room for the unexpected.
