Bathroom renovation. Fixed price, fixed deadline, one person in charge.
We coordinate the entire project under one contract: demolition, plumbing, waterproofing, tiling and sanitary ware. Price and deadline fixed in writing before work starts.
Fixed price and payment by stages. We never ask for most of the amount upfront. You confirm each stage in writing before the next payment.
Demolition + plumbing + waterproofing + tiling + sanitary ware under one contract. One person coordinates the mason, the plumber, the electrician and the tiler. You do not deal with a different team each week.
Greater Lisbon, Setúbal and the Oeste region (Silver Coast). Service area confirmed before the quote. If you are outside it, we say so straight away and waste no one’s time.

The 3 commitments we put in writing
They are not generic. They answer directly what most often goes wrong in bathroom renovations in Portugal.
A clear plan for the days without a bathroom
We agree in writing how many days you will be without access, and what we do if something unexpected appears (for example, a corroded pipe behind the tiles).
Explicit warranty on hidden work
Plumbing and waterproofing under the tiles carry their own warranty. In the cases we come across, this is one of the most common causes of problems that only show up weeks later.
Liability for leaks into the neighbour’s apartment
If our work affects the apartment below, we take on that liability in writing in the contract, rather than leaving you or your neighbour to sort it out.

Budget, mid-range or premium: what changes in practice
The final price is not the only thing that changes: the equipment itself is physically different. Compare the 3 levels side by side.
| Category | Economical | Mid-range | Premium |
|---|---|---|---|
| Best for | An apartment to rent out or sell quickly, on a limited budget | Most requests: a balance of durability, current look and budget | A long-term home, or a high-end property for the upper segment of the market |
| Typical price (5 m² reference) | €2,500 – 4,000 | €4,500 – 7,500 | €8,000 – 14,000+ |
| Toilet | Floor-standing toilet, standard model | Wall-hung toilet: easier to clean underneath, a more "floating" look | Wall-hung toilet with water-saving technology and a high-end finish |
| Washbasin | Pedestal washbasin, no vanity unit | Wall-hung washbasin | Wall-hung vanity unit with countertop and built-in storage |
| Mirror | Not included | Standard mirror above the washbasin | Large mirror with built-in lighting |
| Shower / bathtub | Standard shower tray with curtain | Shower tray with fixed glass screen or sliding door | Walk-in shower (flush with the floor) with frameless fixed glass, freestanding bathtub as an option |
| Wall and floor covering | Entry-level ceramic tile, standard format | Mid-quality porcelain stoneware, less porous and better suited to a wet room | Large formats or microcement: a continuous, joint-free finish with its own curing time |
| Tile height | Up to 1.5 m (the legal minimum), paint above | Floor to ceiling | Floor to the room’s actual ceiling (matching the ceiling height you set in the calculator) |
| Taps and fittings | Basic chrome taps, no specific brand | Mid-range brands (e.g. entry-level Grohe/Hansgrohe) | Top-of-the-range lines with special finishes (brushed steel, matte black) and an illuminated shower head |

The stages of the work, one by one
What physically happens at each stage, and what most often goes wrong at each one, on the market in general.
Demolition
Removal of the old tiles, sanitary ware and flooring, with protection of adjacent areas and rubble removed by a licensed construction-waste operator (RCD).
What commonly goes wrong: This is where corroded plumbing hidden behind old tiles gets discovered. We agree in writing what we do if that happens, before starting.
Plumbing and electrics
Chasing walls for the new water and drainage pipes, and bringing the electrical installation up to wet-room rules: sockets only in zone 3, minimum IPX1 protection rating, and a high-sensitivity residual-current device (≤30mA) mandatory for the whole room.
What commonly goes wrong: Moving the toilet or the shower means more wall chasing than a simple like-for-like swap. That is why a layout change takes longer than replacing fixtures in the same position.
Waterproofing
Waterproofing of the entire floor, reinforced on the shower/bathtub wall, and waterproof covering on the remaining walls up to 1.50 m (the legal minimum), before tiling. The substrate (render) must be completely dry, not just at the surface.
What commonly goes wrong: Tiling before the waterproofing has fully cured (24 hours to several days, depending on the product and humidity) is the most common cause of leaks that only appear weeks later. It is exactly what we cover with an explicit warranty.
Tiling
Wall covering (usually first) and then the floor, with grout suited to a wet room.
What commonly goes wrong: Large formats in a small bathroom mean more cuts and waste. We help you choose a format that works in the real space, not just in the catalogue.
Installation of sanitary ware and fittings
Fitting the toilet, washbasin, shower/bathtub, taps, mirror and final accessories, done near the end of the project, on top of the finished tiling.
What commonly goes wrong: Equipment outside the standard catalogue (special sizes, made-to-order colours) can delay delivery. We check availability before closing the quote.
Final cleaning and handover
Full cleaning of the site, checking of all water and electrical connections, and a final written report with the 5-year legal warranty.
You only pay for each bathroom stage after seeing it work
Plumbing, waterproofing, tiling, sanitary ware: each stage confirmed by you before we release the next payment.
Stage completed
The team finishes the stage (e.g. demolition, infrastructure, tiling).
Checklist signed by you
You see the work and confirm it with a simple checklist. The contractor does not sign off on its own work.
Payment released
Only after your confirmation is the next stage paid.
What we guarantee in the bathroom
Fixed price, in writing
The quote includes every stage before we start. The amount we agree is the amount you pay.
Payment by verified stages
You confirm each stage before the next payment is due. The contractor does not sign off on its own work.
One project manager
A single person coordinates the plumber, the electrician and the mason. You never deal with a different person each week.
5-year legal warranty
Código Civil, Art. 1225º (Portuguese Civil Code: 5-year warranty on building works). It is your legal right, and we state it in the contract with no small print.
Typical bathroom situations
Old bathroom, not renovated in decades
Worn tiling, dated sanitary ware, damp: the most common case.
Preparing the apartment for sale
The bathroom is one of the rooms that adds most value to a property before selling.
Accessibility and reduced mobility
Replacing a bathtub with a shower, grab bars, a more accessible layout.
Waterproofing and leaks
Damp problems affecting the floor below or the neighbouring apartment.

Who contacts us
Representative examples of the kind of project we take on.
The tiling was decades old and the plumbing was already giving trouble. I had heard stories of projects that "stretch to double the time" and I wanted a deadline that would actually be kept.
Fixed quote in writing, with every stage included and the deadline confirmed. Work completed in three weeks, without a single change to the agreed price or schedule.
Talk on WhatsAppIt was our only bathroom. The biggest fear was not the price, it was being without it for weeks with no idea when it would end.
We agreed a written plan for the days without access, with a guaranteed reopening date. It was met exactly as agreed.
Talk on WhatsAppI wanted to sell faster and knew the old bathroom would put buyers off.
Mid-range renovation focused on modern, neutral finishes. The apartment sold within weeks.

Worth reading before you decide
We wrote these guides for people still deciding. No sales pitch: numbers, timelines and what the law requires.
- How much a bathroom renovation costs in Lisbon, Setúbal and the OesteBetween 2,500 and 14,000 € for a reference bathroom of 5 m². What each level includes, how long it takes, and why the figure climbs.
- Bathroom renovation step by step: the order the work has to followThe order of works is not a matter of preference: it is set by the physics of the job. Change it and you pay in rework, almost always weeks later.
- Bathroom waterproofing in Portugal: what the law requires and what quotes leave outIt is not just behind the shower tiles. Portuguese law requires waterproofing across the entire floor and up every wall to 1.50 m, and that is exactly where most quotes cut corners.
Frequently asked questions
Between €2,500 and €14,000 (demolition, plumbing, waterproofing, tiling and sanitary ware), depending on the finish level and whether there are structural changes. A typical 5 m² bathroom falls within this range; see the table above for an estimate tuned to your case. The exact amount is fixed in the quote, before we start.
No, unless you ask for something outside the agreed scope, and always with prior written agreement. The fixed quote includes every planned stage.
Typically between 10 and 30 days, depending on the finish level and whether the layout changes. The calculator above gives a duration estimate specific to your room. We confirm the exact deadline in the quote.
If the work does not touch shared pipework or structural elements, you normally don’t need approval from the owners’ assembly, just notify the building administrator. If shared infrastructure is affected, we help prepare the request.
We agree this in writing before starting, with a specific number of days and a plan for the case where we find something unexpected (for example, a corroded pipe behind the tiles). We do not leave it open.
The plumbing and the waterproofing under the tiles carry their own warranty, explicit in the contract. In the cases we see on the market, they are one of the most common causes of problems that only appear weeks later, so we cover them explicitly, not generically.
We take on that liability in writing in the contract. We do not pass it to you or to the neighbour.
Yes. A small project gets the same commitment on deadlines and response as a large one, never pushed to the back of the queue.
The Portuguese legal warranty for building works on property is 5 years (Código Civil, Art. 1225º, the Portuguese Civil Code). We apply it with no small print.
