Frequently asked questions
How much does a bathroom renovation cost?
A basic bathroom renovation typically costs €8,000–15,000 for a standard bathroom (5–8 m²). Premium finishes, custom tiling and complete replumbing can push costs to €20,000–40,000. Labour accounts for 50–60% of total cost. Costs vary significantly by region.
What is the most expensive part of a bathroom renovation?
Labour is typically the biggest cost at 50–60% of total. For DIY renovations, materials alone (tiles, waterproofing, fixtures) typically run €3,000–8,000 for a standard bathroom depending on quality and finish level.
How long does a bathroom renovation take?
A professional bathroom renovation typically takes 2–4 weeks for a standard 5–8 m² bathroom: 1–2 days demolition, 1 day waterproofing and drying, 2–3 days tiling, 1 day fixtures, 1–2 days plumbing and electrical.
Do I need a permit for a bathroom renovation?
Moving plumbing or electrical installations typically requires a licensed contractor and may require notification to the local authority. Cosmetic renovations (retiling, repainting) within the existing layout generally do not require a permit. Always check your local building regulations.
How can I reduce bathroom renovation costs?
The biggest savings come from: keeping plumbing in the same location (moving drains and supply lines is expensive), choosing standard tile sizes (large-format and custom shapes cost more), and supplying materials yourself while hiring out labour.
