Bathroom Renovation Cost Calculator 2026

The cost of a bathroom renovation in Poland (2026) depends on floor area and finishing standard. The economy level is about PLN 1,500/m², standard about PLN 2,800/m², and premium about PLN 5,000/m². For a typical 6 m² bathroom at the standard level this gives about PLN 16,800, covering materials, labour and fixtures.

The total cost splits roughly into: materials (tiles, adhesive, grout, waterproofing, skim coats) about 45%, labour (demolition, plumbing, electrics, tiling) about 35%, and fixtures and fittings (bath/shower, basin, WC, taps, radiator) about 20%. The proportions shift with more expensive fixtures.

Labour is about 35% of the total cost. For a 6 m² standard bathroom that is about PLN 5,880. Rates per task: tiling PLN 80–150/m², plumbing PLN 1,500–3,000 per point, fitting sanitaryware PLN 800–1,500. In large cities rates are 20–30% higher.

The economy standard (PLN 1,500/m²) means cheaper domestic tiles, basic fixtures and a simple layout. Standard (PLN 2,800/m²) means mid-range tiles, a shower enclosure and good-quality taps. Premium (PLN 5,000/m²) includes large-format tiles, branded fixtures, underfloor heating and concealed cistern fittings.

Tiles are a significant part of the materials cost. Ceramic tile prices start at PLN 30–50/m² (economy), through PLN 60–120/m² (standard), up to PLN 150–400/m² (large-format porcelain, decorative tiles). On top of the tile price you must add adhesive, grout, trims and about 10% spare for cuts.

A full 6 m² bathroom renovation usually takes 2–4 weeks. Wet works and drying take the most time: screeds, waterproofing and tile adhesive require technological breaks. Tile and fixture deliveries can also cause delays — it is worth ordering them in advance.

Yes, the calculator estimates fixtures and fittings as about 20% of the total cost. This covers the bath or shower, basin with vanity, WC, taps and a towel radiator. If you choose top-shelf fixtures, the real share of this item can rise to 30–40%.

A full-service renovation firm simplifies coordination and takes responsibility for everything, but is 10–20% more expensive than hiring trades yourself. Hiring separately (tiler, plumber, electrician) can be cheaper but requires coordination and time. For a bathroom, a full-service offer usually pays off.

A standard bathroom renovation (replacing tiles, fixtures, painting) requires no formalities. Permits or notifications may be needed when interfering with shared building installations, moving sewage risers or changing load-bearing walls — these require the housing cooperative’s consent and a design.
