As a rule of thumb, here’s what to expect for a full refurbishment (all prices include labour and materials):
| Budget Range & Low-complexity | Medium Range & Complex | High End & Very Complex | |
|---|---|---|---|
| Small bathroom (4-5 m2) | £7k + | £8k+ | £9k+ |
| Medium Bathroom (7-10 m2) | £8k+ | £9k+ | £10k+ |
| Large bathroom (10-14 m2) | £9k+ | £10k+ | £11k+ |
| Very large bathroom (15 m2+) | £10+ | £11k+ | £12k+ |
Note: If you’re turning a room into a bathroom for the first time, allow an extra £2k–£3k depending on complexity.
Why We Only Do Full Refurbishments
We don’t take on patch-up jobs. That’s because the real work lies behind the tiles and fittings — in the plumbing, flooring, walls and structure. The visible suite and finishes usually make up less than 30% of the job.
Many contractors cut corners by leaving old floors, walls or pipework in place. But without a solid foundation, even the most stylish bathroom won’t last.
We’ve seen the risks first-hand. In one recent project, the bathroom looked fine on the surface — but underneath, the floor joists were completely rotted from a long-term leak. They were so unsafe that someone could easily have fallen through a two-metre drop. Problems like this are common in bathrooms over 10 years old.
That’s why we start fresh:
- Remove everything back to the structure
- Insulate walls for warmth and efficiency
- Update all plumbing
- Reinforce floors and ceilings
- Waterproof critical areas
- Seal between baths/showers and walls
- Fit new ceilings and lighting
The result is a bathroom that meets today’s standards — built properly, and built to last.
What Affects the Price Most
Several factors influence the overall cost:
- Age of the existing bathroom
- Type of construction (timber frame, concrete, etc.)
- Layout changes
- Shape and size of the room
- Flooring and wall finishes chosen
- Bathroom suite style and quality
- Extras such as recesses, shaver sockets, extractor fans, downlights and feature lighting
Value Added
While bathrooms can be expensive, they’re one of the most valuable upgrades you can make to a property. Many homeowners choose to refurbish before selling, as a modern bathroom is a strong selling point and adds measurable value.
