A bathroom renovation is one of the most significant investments in a home — and one that returns the most in daily quality of life and resale value. Prices in Athens vary widely depending on size, existing condition, whether plumbing needs relocating and the quality of materials chosen.
What does a bathroom renovation cost in Athens? (2026 price guide)
Below are realistic price ranges including labour and materials for a complete renovation: demolition, waterproofing, tiling, plumbing connections and fixtures.
What is included in the price — and what costs extra?
A complete bathroom renovation normally covers: demolition and waste removal, floor levelling, waterproofing membrane, floor and wall tiling, plumbing for shower, toilet and basin, electrical for underfloor heating and lighting, and final fitting of shower enclosure, fixtures and accessories.
What typically costs extra: moving load-bearing walls, replacing old pipework, installing underfloor heating from scratch, large-format or natural stone tiles, designer fixtures. In older Athens apartments with original pipes, budget 10–15% extra for concealed surprises.
Labour vs materials: what drives the total cost?
In Athens bathroom renovations, labour accounts for 50–65% of the total. Three mandatory specialists drive that figure: a licensed plumber, a licensed electrician and a certified waterproofing installer. These certifications are not optional.
Material costs vary significantly. Basic ceramic tiles start from €15–€35/sqm; premium porcelain from €60–€200/sqm. Fixtures range from €400 for a basic set to €5,000+ for premium designer items. Focus budget on plumbing and waterproofing — those are not areas to cut costs.
Waterproofing: why it costs what it costs
Waterproofing is the single most critical component of any bathroom renovation. Greek building regulations require certified installation of a moisture barrier in all wet rooms. A proper installation costs €800–€2,000 for a standard bathroom — and is not a cost to reduce. Insurance companies routinely deny water damage claims where the waterproofing was not properly certified.
Common cost traps — and how to avoid them
The most expensive surprise in bathroom renovations is concealed moisture damage. Old pipework needing replacement can add €2,000–€6,000 to the budget. A moisture assessment before work begins (typically €150–€300) can identify these risks before walls are opened.
How to compare quotes correctly
Always get at least three quotes. Check that all include: fixed price or cost ceiling, waterproofing system specification, clarity on included materials vs client-supplied items, VAT stated separately and payment schedule. An incomplete quote is incomplete — request everything in writing before signing.
Frequently asked questions
How long does a bathroom renovation take?
A small bathroom takes 2–3 weeks. A medium bathroom with full plumbing work takes 3–5 weeks. A large bathroom or one with significant plumbing relocation can take 5–8 weeks. Always build buffer time into your planning.
Do I need a building permit for a bathroom renovation?
For a standard bathroom renovation — replacing tiles, fixtures and fittings — no permit is required in Greece. If you plan to move load-bearing walls or make significant structural changes, you will need approval from your municipality's urban planning office.
Can I live at home during the bathroom renovation?
If you have a second bathroom, most people stay at home. If the renovated bathroom is the only one, you will need alternative arrangements for 3–6 weeks. Some contractors can phase work to maintain toilet access throughout — discuss this when requesting quotes.
How do I choose the right contractor in Athens?
Check that the contractor is TCG-registered (Τεχνικό Επιμελητήριο Ελλάδας), has relevant liability insurance, provides a written quote with fixed costs, and can show verifiable references from comparable projects. Price alone is never the right criterion.
What is the most common mistake in bathroom renovations?
Choosing tiles and fixtures before finalising the layout. If the layout changes after materials are ordered, cutting losses on premium tiles is costly. Lock in the plan first, then select materials. Also: never skip the waterproofing survey before demolition.
