What affects bathroom renovation costs?
The size of the bathroom, fittings selected, amount of plumbing work and standard of finish can all significantly affect the overall renovation budget.
Bathroom suite and fittings
Baths, showers, toilets, basins, taps and furniture are available across a wide range of prices. Your specification can therefore make a large difference to the overall cost.
Plumbing work
Keeping fittings in similar positions can sometimes simplify a project, while moving pipework and drainage may require additional plumbing work.
Tiling
The amount of wall and floor tiling required, tile size and installation complexity can all affect labour and material costs.
Electrical work
Lighting, extractor fans and other electrical work may need to be included in the project depending on the planned design.
Removing the existing bathroom
Removing old fittings, tiles and flooring can add labour and waste-disposal costs before the new bathroom can be installed.
Compare bathroom quotations
Make sure quotations cover a similar specification when comparing bathroom businesses so that you can understand what each price includes.
An illustrative quote comparison
One renovation keeps the layout; another moves fixtures and renews more of the room.
Use the same fixture and layout plan. Compare removal, preparation, services and finishing rather than a fixture-only estimate.
