Bathroom Renovation FAQs
How long does a bathroom renovation take?
A standard bathroom refurbishment typically takes 5–10 working days. Larger bathrooms or wet room conversions may take 2–3 weeks.
Do I need planning permission for a bathroom?
Most bathroom renovations don't require planning permission. However, if you're converting a bedroom into a bathroom or making structural changes, you may need Building Regulations approval.
Should I use a main contractor or individual trades?
A principal contractor coordinates all trades (plumber, tiler, electrician) and takes full responsibility for the project. This typically costs 10–15% more but saves significant time and reduces risk.
What's the biggest cost factor in bathroom renovation?
Labour accounts for 50–60% of the total cost. Tile choice and sanitary ware specification are the biggest material cost variables. Premium tiles can cost 3–5x more than budget options.
