How long a renovation really takes in Barcelona
Almost every overrun we see was decided before the first wall came down. The programme is not broken on site — it is broken at the ordering stage.

Short answer
How long does each type of job take?
A bathroom takes 10–18 working days, a kitchen 12–25, and a full flat renovation 10–14 weeks on site. Add four to eight weeks of preparation in front of that for decisions, permits and joinery lead times. If you are abroad, budget calendar time, not site time: August in Spain is genuinely quiet and suppliers close.
A bathroom takes 10 to 18 working days, typically around 12. A kitchen takes 12 to 25 working days, typically around 18. A full flat renovation takes 10 to 14 weeks on site. All three figures are working days, not calendar days.
Why that distinction matters
12 working days is roughly two and a half calendar weeks once weekends are counted, and longer if a public holiday falls inside. Spain has a generous holiday calendar and August is genuinely quiet: suppliers close, and a fortnight can disappear without anybody being at fault.
What the on-site figure excludes
The design and decision stage before it, and any permit application. Neither is site time, but both are calendar time. A realistic total for a full renovation is the site programme plus four to eight weeks of preparation in front of it.
| Type of job | Time on site | Preparation in front of it | Where the delay actually comes from |
|---|---|---|---|
| Full bathroom | 10–18 working days | 2 to 4 weeks | Waterproofing has to cure, and sanitaryware ordered late |
| Full kitchen | 12–25 working days | 4 to 8 weeks | Made-to-measure units and the worktop, templated only once the units are in |
| Full flat, 70 m² | 10 weeks | 4 to 6 weeks | Tile and flooring choices left open after the start date |
| Full flat with structural work | up to 14 weeks | 6 to 10 weeks | Architect project and major licence, neither of which the builder controls |
| Anything scheduled across August | Add 2 to 4 weeks | — | Suppliers and workshops close, and the calendar absorbs it |
Week by week
What actually happens in each phase?
Knowing the sequence lets you tell the difference between a site that is quiet because it is waiting on curing time and a site that is quiet because nobody is coming.
A full renovation, in order
- Weeks 1–2: strip-out, licensed waste removal, exploratory openings to confirm structure and services
- Weeks 2–4: plumbing and electrical first fix, reinforcements for wall-hung items, everything photographed before closing up
- Weeks 4–6: partitions closed, waterproofing to wet areas and its curing time, screeds
- Weeks 6–9: wall and floor tiling, flooring throughout
- Weeks 8–11: internal joinery, decoration, kitchen and bathroom furniture installed
- Final week: second fix, appliance commissioning, snagging, clean and handover with certificates
The days that look idle but are not
Waterproofing membranes, screeds and adhesives all need curing time, and tiling onto an uncured substrate is how you get lifting tiles two years later. If someone offers to compress those days, that is not efficiency.
Where a bathroom differs
In a single bathroom the same sequence is squeezed into a fortnight, and curing time becomes the dominant constraint rather than the trades. That is why the shortest honest bathroom programme is around a fortnight and not five days.
Delays
What causes almost every overrun?
In practice there are four, and three of them are decided before work begins rather than during it.
Late ordering of long-lead items
Bespoke kitchen units take four to eight weeks to manufacture. External joinery is similar. If either is ordered after the strip-out has started, the entire site eventually stops and waits. These are ordered before demolition, not after.
Decisions still open at the start
A layout agreed "in principle" is not agreed. Every socket position, tile choice and appliance model left open becomes a pause later, and the pause is always longer than the decision would have taken.
What appears when walls open
Corroded steel beams, a soil stack in worse condition than expected, aluminium wiring. Genuinely unforeseeable, but far less likely to derail things if exploratory openings were made in week one rather than discovered in week five.
Permits and the comunidad
Anything touching a communal element — the stack, the façade, a riser — needs the owners association to agree, and associations meet on their own schedule. Structural work needs a municipal licence with its own processing time. Both are calendar time you cannot compress once you are in it.
If you are abroad
How do you keep a programme honest from another country?
You cannot inspect the site, so the programme itself has to be the instrument. That means it must be specific enough to be checked against photographs.
What to ask for in writing
- A start date and a duration in working weeks, not "about three months"
- Named milestones with dates: strip-out complete, first fix complete, waterproofing done, tiling complete, handover
- A weekly photo report tied to those milestones rather than general progress shots
- A named site manager you can contact directly, in your language
- What happens if a milestone is missed, agreed before it is
The one milestone worth watching closely
First fix complete, with photographs of every wall showing pipework and cabling before it is covered. If that milestone slips, everything after it slips too, and it is the last point at which changes are still cheap.
The realistic expectation
A well-run job of this kind finishes within a week or so of its programme. Anything promising a full flat in half the normal time is either leaving work out or has not counted the curing days.
Frequently asked
Common questions
Between 10 and 18 working days, typically around 12. That is roughly two to three calendar weeks. Waterproofing and its curing time are the days that cannot be compressed.
Between 12 and 25 working days on site, typically about 18. The bespoke units take four to eight weeks to manufacture and must be ordered before the strip-out, not during it.
10 to 14 weeks on site, plus four to eight weeks beforehand for design, decisions, ordering long-lead items and any permit application. The preparation is calendar time even though it is not site time.
Four reasons: long-lead items ordered late, decisions still open when work starts, genuine surprises found when walls open, and waiting on the owners association or a municipal licence. Only the third is truly unavoidable.
Be aware of it rather than avoid it. Many suppliers and workshops close for a fortnight, so a job spanning August needs its material deliveries scheduled around that gap or it simply pauses.

Phased renovation
Renovating in phases is not renovating in pieces. The difference between the two is a plan — and it is the difference between spreading the cost and paying twice.
Renovation contract
The contract is not a formality to get the work started: it is the document that decides who pays for every surprise. From 1,500 km away, it is also your main lever.
Small kitchens
Period flats in Barcelona put the kitchen at the back, next to the gallery, with whatever metres were left over. They cannot be stretched — but they can be worked.
Duplex staircases
The staircase is the most expensive piece of furniture in a duplex and the only one you cannot return. It gets decided once — with the regulations and the floor structure in front of you.
