Quick Answer: How Much Does a Bathroom Renovation Cost?
A bathroom renovation in the UK typically costs £4,500 to £10,000 for a standard family bathroom at mid-range specification, with budget refreshes possible from £2,500 and premium en-suite or wet room projects running £12,000 to £20,000 or more. Suite quality, tiling extent, and whether plumbing positions are changing all significantly affect the final figure.
Bathroom Renovation Cost by Specification
| Specification | Typical Cost | What’s Included |
|---|---|---|
| Budget refresh | £2,500 to £4,500 | Basic suite, partial tiling, existing layout |
| Mid-range | £4,500 to £10,000 | Quality suite, full tiling, new flooring |
| Premium/wet room | £12,000 to £20,000+ | Walk-in shower or wet room, natural stone tiling, underfloor heating |
What Affects Bathroom Renovation Cost?
Suite Quality
Basic ceramic suites cost considerably less than premium ranges with soft-close fittings, thicker ceramic, and designer styling. Mid-range suites offer a sensible balance for most family bathrooms.
Tiling Extent and Material
Full height tiling on all walls costs significantly more than half-height tiling with painted upper walls. Material also matters: ceramic tiles are the most affordable, porcelain sits in the mid-range, and natural stone commands a premium. See our patterned floor tiles guide for style ideas.
Plumbing Changes
Keeping the bath, toilet, and basin in their existing positions keeps plumbing costs down. Moving any of these requires new pipework, which adds both cost and time, particularly if floor boards need lifting on an upper floor bathroom.
Wet Rooms and Walk-In Showers
A wet room requires specialist tanking to fully waterproof the room and a properly graded floor for drainage, both of which add cost compared to a standard shower enclosure over a tray.
Bathroom Renovation Cost Breakdown
| Item | Typical Share of Budget |
|---|---|
| Suite (bath, toilet, basin) | 20 to 30% |
| Tiling (materials and labour) | 20 to 25% |
| Plumbing | 15 to 20% |
| Flooring | 10% |
| Electrics and lighting | 5 to 10% |
| Installation labour (remaining) | Balance |
Small Bathroom Renovation Considerations
Smaller bathrooms cost less in absolute terms but can carry a higher cost per square metre, since fixed costs like plumbing labour and tiling preparation are spread across less area. Choosing space-efficient fittings and a wall-hung toilet can help maximise a compact layout. See our small space design guide for layout ideas that apply well to compact bathrooms.
Bathroom Flooring Options
Bathroom flooring needs to be fully waterproof. Tile and waterproof click vinyl are the standard choices, covered in detail in our types of flooring guide, with carpet and standard laminate best avoided entirely in wet areas.
DIY vs Professional Bathroom Renovation
Tiling and cosmetic updates such as repainting are realistic DIY tasks for a confident homeowner, but plumbing and electrical work in a bathroom must be carried out by a qualified professional to meet Building Regulations Part P for electrics in wet zones, and to avoid costly leaks from poorly sealed plumbing joints.
How to Reduce Bathroom Renovation Cost
- Keep the existing plumbing layout wherever possible
- Choose a mid-range suite rather than a premium designer range
- Tile a feature wall rather than full height tiling throughout
- Get multiple itemised quotes and compare labour and materials separately
- Handle painting and simple finishing touches yourself
Frequently Asked Questions
How long does a bathroom renovation take?
A standard bathroom renovation typically takes one to two weeks, while a wet room conversion with full tanking can take two to three weeks given the additional waterproofing and drying time required.
Is a wet room worth the extra cost?
Wet rooms suit properties prioritising accessibility or a sleek, minimalist look, and can add value in the right property, though the additional tanking and grading cost should be weighed against a standard shower enclosure.
Do I need a building regulations certificate for a bathroom renovation?
Electrical work in bathroom zones and significant plumbing changes typically need to meet Building Regulations, with qualified tradespeople able to self-certify compliant work.
What is the cheapest way to refresh a bathroom?
Regrouting tiles, repainting, updating taps and fittings, and replacing a toilet seat can transform a tired bathroom’s appearance for a fraction of a full renovation cost.
Does a bathroom renovation add value to a house?
A well-executed bathroom renovation is widely considered one of the higher value-adding home improvements, particularly for a property with only one existing bathroom.
Expert Insight
Bathroom fitters commonly report that undiscovered issues behind existing tiling, such as damp subfloor or ageing pipework, are the most frequent source of budget overruns, making a thorough survey before finalising a budget a worthwhile investment.
Final Thoughts
Bathroom renovation costs in the UK vary widely based on suite quality, tiling extent, and whether plumbing positions change. Keeping the existing layout and choosing mid-range fittings offers the best value for most homeowners, while wet rooms and premium finishes suit those prioritising a specific look or accessibility need.
Planning a bathroom renovation? Get your plumber to assess pipework condition before finalising your budget, since hidden issues behind old tiling are the most common cause of unexpected cost.
