A 6 m² bathroom can cost 9,000 PLN or 55,000 PLN. The difference lies not in the size, but in the decisions you make at the planning stage — before you hire a contractor.
Problem
Bathroom renovation is one of the most misleading projects when it comes to estimating costs. The small area (4–10 m²) creates a false sense of low cost — because every square metre here is more expensive than in other rooms.
Why? A bathroom combines several trades at once: — Plumbing: new drains, connections for shower, sink and toilet — 2,500–7,000 PLN — Electrics: circuits for underfloor heating, fan, IP44 sockets — 1,200–3,500 PLN — Tiling: labour 70–130 PLN/m² for small format, up to 200 PLN/m² for large-format slabs — Anhydrite or self-levelling screed for underfloor heating — 38–65 PLN/m²
In 2026, labour costs have risen by 12–18% year-on-year. Tiling crews are the most in demand — waiting time is 4–10 weeks.
Solution
Approximate costs for a 6 m² bathroom renovation in Poland 2026 (excluding fittings and sanitary ware):
Budget standard — 9,000–17,000 PLN Refreshing existing installations, new tiles in the wet zone, painting remaining walls, vinyl panel flooring or basic porcelain. Ideal for a bathroom in good technical condition.
Optimal standard — 18,000–32,000 PLN Full ceramic cladding on walls and floor, electric underfloor heating, replacement of plumbing connections, new electrical solutions. A typical renovation for an apartment before sale or modernisation.
Premium standard — 34,000–60,000+ PLN Large-format slabs 60×120 or 120×240 cm, walk-in shower, water underfloor heating, concealed toilet cistern, built-in LED lighting. A bathroom as a relaxation space.
Prices include labour and finishing materials. Fittings (taps, drain, toilet bowl, shower enclosure/bath) are an additional 3,000–25,000 PLN depending on choice.
Checklist
- Measure the bathroom: length, width, height, window and door positions
- Assess the condition of installations — replacing pipes adds 2,500–7,000 PLN to the budget
- Decide on underfloor heating before the screed is poured
- Choose tile format BEFORE pricing labour — format affects the cost
- Book a tiling crew 6–8 weeks in advance (2026: high demand)
- Plan fittings and sanitary ware separately — they account for 20–40% of the total budget
- Add a 20% buffer for surprises under old tiles (mould, rot, old screeds)
- Calculate your renovation estimate online before starting talks with contractors
