Bathroom renovation step by step — from idea to keys
8 mandatory stages, realistic timing (2-3 weeks), typical budget and costly mistakes.
A full bathroom takes 12-18 working days — if things go well. Stages: demolition (1 day), rough plumbing (2 days), electrical (1 day), self-levelling screed (1 day + 7 days curing), waterproofing (1 day), tiling (3-5 days), sanitary objects (1 day), cleaning + finishing (1 day).
Realistic 2026 budget in Germany for a 6 m² turnkey bathroom: 8,500–14,000 EUR. Includes demolition, all installations, mid-to-upper tile quality, wall-hung toilet, walk-in shower, hung furniture.
Mistake #1: skimping on waterproofing. Bad waterproofing means infiltration in 6-12 months and full rework. The cost difference between OK and premium waterproofing is under €200 on a standard bathroom.
