By Pascal Niggli · Co-founder of remodel.pt · Last updated July 2026
A bathroom rebuild in Portugal costs €12,000–€22,000 for a standard 6–8m² wet room and takes 4–8 weeks from quote acceptance to handover. Waterproofing, plumbing relocation, tiling, and ventilation are the biggest cost drivers, and quotes for the same scope routinely vary by 30–50% between contractors, which is why Remodel.pt checks every quote against regional project data before you see it.

What Drives the Cost of a Bathroom Rebuild?
Waterproofing quality and whether the drain or waste line moves are the two biggest cost and risk factors in a Portuguese bathroom rebuild.
Older Portuguese buildings often have inadequate or failed waterproofing beneath old tile, which isn't visible until demolition starts. Budgeting a contingency of 10–15% for this discovery is standard practice. Moving a shower or WC to a different wall position adds plumbing cost and, in condominiums, may require notifying the building administration.
How Long Does a Bathroom Rebuild Take?
4–8 weeks from quote acceptance to handover, with waterproofing cure time and tile adhesive drying accounting for several of those days even though they involve no active labour.
Waterproofing membranes typically need 48–72 hours cure time before tiling can begin, and grout needs 24–48 hours before the shower can be used. These are fixed constraints regardless of contractor speed.
What to Check Before You Start
Confirm the building's plumbing riser layout and, in a condominium, whether moving fixtures requires notifying the administration before signing a scope.
Most cosmetic bathroom rebuilds, same fixture positions, new tile and fittings, need no permit. Relocating the WC or shower to a different position within the room is usually fine to notify rather than formally permit, but confirm this with your contractor before demolition, since building-specific rules vary.
