How much does a bathroom renovation cost in the Algarve?

Nobody can price your bathroom from the room’s dimensions, and a builder who quotes over the phone without asking where the soil pipe runs is quoting for a different bathroom. The cost is set by how much of the room’s hidden half you disturb. Surfaces are the cheap part. Everything behind them is where the money goes.

What actually decides the figure

A renovation quote is really four jobs stacked on each other, and each one can be small or large independently.

1. Strip out. Removing tiles, screed, old sanitary ware and sometimes a partition. Skip hire and disposal belong here, and in a fifth floor apartment with no lift this line is bigger than people expect.
2. First fix. Water, waste and electrics, plus any wall chasing. If the shower moves to the opposite wall, this item multiplies. If everything stays put, it can be nearly nothing.
3. Waterproofing and tiling. The membrane under a walk in shower, the levels and falls, then the tiling itself. Large format tiles, mosaic borders and anything that needs cutting around a niche are slower to lay than plain thirty by sixty centimetre wall tiles.
4. Second fix and making good. Sanitary ware, taps, screens, mirrors, and the plastering and painting where old meets new.

The Algarve specifics that change the number

Local conditions are not decoration here, they genuinely move the price.

• Hollow clay block and rendered walls. Chasing services into them is routine, but a wall that turns out to be structural or hiding an old cast waste stack stops the plan.
• Apartment soil pipes. In a block, the position of the vertical stack is fixed. A design that ignores it becomes a step in the floor, a boxed in run, or a pumped waste, all of which cost more than moving the design.
• Your water, which is not the region’s water. Hardness here is a supply zone fact, not an Algarve fact: the published figures run from 30 mg/L of calcium carbonate in Portimão to 300 or 400 in zones fed only by boreholes. Where the water is hard it decides what happens to glass screens, chrome and shower cartridges over the following years, and a cheap thermostatic valve becomes a false economy you meet again in three summers. Where it is soft that argument does not apply, so check your own zone before paying for it. (Figures: EMARP, water quality control data, first quarter 2026, for Portimão; Taviraverde, water quality FAQ and first quarter 2026 edital, for the borehole-only zones.)
• Season and availability. Trades in the Algarve are busiest before the summer, and a bathroom booked for April is competing with every villa preparing for the season.
• Holiday home logistics. Access, key handover, someone to take deliveries and the fact that decisions are being made from another country all lengthen a job that would run smoothly for an owner living in it.

Why no euro range appears here

Because the per square metre numbers published for Portugal are national averages that flatten exactly the differences described above. A range invented for this page would be quoted back at us by readers who then find their real quote nowhere near it. Scope, hidden pipework and finish level set the figure, and they are yours, not a page’s.

What we can do now is price your actual bathroom for free, from photos and a few answers, which is a more useful number than any average. The service page for bathroom and kitchen renovation in the Algarve covers what the work includes and how a request is handled.

How to make quotes comparable

Ask every quote to state the same six lines: strip out and disposal, first fix, waterproofing, tiling with the tile format assumed, sanitary ware with brands named, and making good. Decide who buys the tiles and the sanitary ware, because a quote that excludes them looks cheaper than one that includes them and neither is lying. Then ask what happens if the wall behind the old tiles turns out to be damp, because in a bathroom that is not a rare surprise, and the answer tells you how the rest of the job will be run.
