What Affects Bathroom Renovation Costs?

Bathroom Size
Larger bathrooms require more materials, more labour time, and often more complex plumbing work.
Scope of Work
A simple refresh (new suite, tiles) costs less than moving plumbing or structural changes.
Quality of Materials
Budget tiles vs. premium porcelain, standard suite vs. designer brands significantly impact cost.
Special Features
Underfloor heating, wet room conversion, or walk-in showers add to the overall cost.

- Experience level: Established tradespeople with good reputations charge more—but deliver reliability
- Insurance & guarantees: Properly insured work with guarantees costs more than cash-in-hand jobs
- Quality of finish: Laser-leveled tiling and professional tanking take longer but last longer
- Hidden issues: Older properties in Dartford often have hidden problems that budget quotes don't account for
