Bathroom Renovation FAQ
Everything you need to know about planning, regulations, and executing a successful bathroom remodel in the UK.
A standard bathroom renovation typically takes between 3 to 5 weeks. A simple cosmetic update (like replacing a vanity and re-grouting) may take 1 to 2 weeks, while a full gut-and-remodel involving structural changes, new plumbing, and custom tiling can take 6 to 10 weeks or more.
Generally, no. Internal renovations like replacing fixtures, tiles, or plumbing within the existing footprint of your bathroom do not require planning permission. However, if you are extending the room, moving structural walls, or altering external windows, you may need permission or must comply with Building Regulations.
Labour and plumbing modifications are typically the most expensive parts of a bathroom renovation. Moving existing water supply lines, waste pipes, or ventilation systems requires skilled tradespeople and can significantly increase the overall cost compared to simply replacing fixtures in their current locations.
While DIY can save money on cosmetic tasks like painting or installing a vanity, tasks involving plumbing, electrical work, and waterproofing (tanking) should always be handled by certified professionals. Improper waterproofing or electrical work can lead to severe structural damage, mould, or safety hazards.
