Altea makes bathroom renovations more complex than they first appear. It’s not just about the size of the bathroom or the quality of the materials — though those matter too — it’s that several factors converge here that simply don’t exist in other locations: the Casco Antiguo with its stone walls and impossible staircases, the seasonal demand that spikes in summer, owners who aren’t present during the works, and a marine environment that destroys low-quality taps within three years.
I’ve seen bathroom renovation quotes in Altea spike 30% above the initial price simply because nobody had warned the owner what it meant to move rubble down a narrow street in the historic centre with nowhere to park a skip. This article exists so that doesn’t happen to you.
Bathroom renovation prices in Altea range from €2,500 to €9,000 depending on the type of work, the condition of the existing installations and the exact location of the property. Below you’ll find every factor broken down.
| Aspect | What you need to know |
|---|---|
| Partial renovation | From €2,500 (no layout changes) |
| Standard full renovation | €3,500–€6,500 (4-6 m² bathroom) |
| Design / luxury renovation | €7,000–€12,000 or more |
| Average timeframe | 5–10 working days |
| Most expensive line item | Floors and walls (25-35% of budget) |
| Casco Antiguo surcharge | +20-30% above standard price |
| Best time to renovate | October–February (lower demand, better availability) |
How Much Does It Cost to Renovate a Bathroom in Altea? Price Ranges by Type of Work
The first question to answer is what type of renovation you actually need. Updating the look of a bathroom without touching the installations is very different from a full gut renovation. The price difference between the two can be €3,000 or more, and this confusion is one of the most common reasons why quotes vary so dramatically between contractors.
Partial renovation or cosmetic refresh: from €2,500
A partial renovation covers replacing the sanitaryware (toilet, basin, bath or shower tray), updating the taps and renewing the furniture — without touching the plumbing installations or structure. It’s the fastest option — three to five working days — and the least disruptive.
Converting a bathtub to a shower, one of the most requested jobs in Altea, falls within this range: between €690 and €1,450 depending on the type of shower tray, the screen chosen and the condition of the walls once the bath is removed.
This option has a clear limit: if the installations haven’t been touched in over 20 years, the cost of not renewing them now could be far higher in two years when a leak reveals the pipes were already at their limit.
Standard full renovation: €3,500–€6,500
This is the most common type of renovation in Altea. It includes demolition of existing tiling, renewal of the plumbing, updating of the electrical installation, new floor and wall tiles, and all elements: sanitaryware, shower screen, vanity unit and taps.
For a 4 m² bathroom the average price in Altea sits between €3,200 and €4,500. For a 6 m² bathroom, between €4,500 and €6,500. These are indicative ranges using mid-to-high quality materials, which makes sense in a coastal location for reasons I explain later.
Design or luxury renovation: from €7,000
Large-format porcelain (DEKTON, natural stone), thermostatic taps, walk-in shower with microcement, bespoke furniture, integrated lighting. In Altea Hills and in some historic centre properties renovated as luxury homes, this is the expected standard.
These renovation prices have no defined ceiling: from €7,000 to over €15,000 depending on materials and project complexity.
Cost Breakdown: Where Your Budget Goes
One of the most frequent problems when getting a quote is receiving a lump sum with no breakdown. When you have a quote itemised by trade, you can compare contractors fairly and spot where quality adjustments are being hidden.
| Line item | Indicative range | % of total |
|---|---|---|
| Demolition and waste removal | 350–800 € | 8-12% |
| Plumbing and drainage | 600–1,100 € | 15-20% |
| Electrical and lighting | 200–450 € | 6-10% |
| Floors and walls (materials + fitting) | 900–2,200 € | 25-35% |
| Sanitaryware (toilet + basin) | 300–900 € | 10-15% |
| Shower screen or enclosure | 150–400 € | 5-8% |
| Vanity unit + taps | 250–700 € | 8-14% |
| Total labour | 1,200–2,400 € | 30-40% |
Demolition and waste removal
In a standard Altea flat — with a lift and normal access — demolition presents no surprises: between €350 and €650. The problem is that in the Casco Antiguo this line item can double or triple. Rubble has to be carried down narrow staircases by hand, you can’t always park a skip on the street, and sometimes specific municipal permits need to be arranged.
Plumbing and drainage
A full plumbing renovation for a bathroom runs between €600 and €1,100. This covers replacing the supply pipes, drains, valves and connections. If the building is old and the original installation is lead or galvanised iron — common in Altea properties from the 1970s and 80s — costs can rise significantly because the section running from the mains also needs attention.
Electrical and lighting
Between €200 and €450 for a complete electrical installation with light points, a socket for the hairdryer and a backlit mirror. Modern bathrooms increasingly include LED lighting integrated into the mirror and false ceiling, which can add €150 to €300 but greatly improves the visual result and energy consumption.
Floors and walls: the most expensive line item
The one with the greatest impact on the final budget. Tiling costs depend directly on the material chosen:
- Basic ceramic: €10–18/m²
- Standard porcelain: €18–35/m²
- Large-format porcelain: €35–60/m²
- Microcement: €60–100/m²
- Natural stone or DEKTON: €80–150/m²
Fitting adds between €16 and €35/m² on top. For a 5 m² bathroom with 2.5 m ceilings, the total surface to cover is approximately 20 m². The difference between choosing basic ceramic and large-format porcelain can be over €1,000 on this line item alone.
Sanitaryware, shower screen and vanity
A wall-hung toilet in mid-range runs between €350 and €650. A floor-standing standard toilet, between €120 and €250. The vanity unit with integrated basin goes from €200 to €600 in mid-range and easily exceeds €1,000 in design pieces. A quality sliding shower screen starts at €180.
What Makes Altea Different from Other Locations
This is the section that sets this article apart from any generic bathroom renovation guide. Altea is not just any town, and that has direct consequences for the price of your project.
The Casco Antiguo adds 20 to 30% to the cost
If your property is in Altea’s historic centre — the cobbled streets climbing up towards the church — you’re in a different category. The buildings date from the 18th or 19th century, with stone or irregular masonry walls, bathrooms that tend to be small with unusual shapes, and difficult access for materials and waste.
The surcharge compared to a standard flat is between 20 and 30%. It’s not that contractors charge more for the postcode: the logistics are genuinely more expensive. More labour hours, more difficult material transport, and demolition work that’s often slower because the structures are irregular.
If you have a property in the Casco Antiguo, get the quote after the contractor has visited the space in person. A blind quote is worthless here.
Seasonal demand: why renovating in winter costs less
Altea has a very particular dynamic: many owners are temporary residents or have a second home here. In summer, most renovation companies are fully booked because peak demand for new builds and owners wanting properties ready for their holidays coincide.
Between October and February, demand drops. Companies have more availability, lead times are shorter and — though this isn’t something contractors will put in their brochure — there’s more room to negotiate on price.
If you can choose the timing, renovating in the low season can save you between 10 and 15% compared to doing the same work in April or May.
Salt air and marine humidity: materials you can’t choose lightly
Altea’s marine environment is aggressive towards certain materials. Low-quality chrome taps, for instance, can rust and lose their finish within two or three years on the front line of the coast. The same applies to low-quality aluminium hardware and some interior wall paints that aren’t formulated for humid environments with salt in the air.
For a bathroom in Altea, it’s worth investing in:
- Brass taps with quality chrome finish or stainless steel — not zinc with a chrome wash
- Non-slip porcelain tiles for the floor (also required in bath and shower areas by regulations)
- Neutral fungicidal silicone for joints and junctions — not standard acid silicone
- Bathroom furniture with moisture-resistant board (PVC or lacquered MDF) — not standard chipboard
This isn’t a design indulgence: it’s durability. A bathroom in Altea using materials intended for inland interiors may need maintenance interventions in five years that would have been avoidable with a better initial choice.
Altea Hills: a completely different price bracket
Properties in Altea Hills have bathrooms of 15-20 m² or more, with direct access from the bedroom and views that turn the renovation into something closer to an interior design project. In these homes, bathroom renovation budgets rarely fall below €10,000 and frequently exceed €15,000–€20,000 when working with premium materials and design.
Do I Need a Permit to Renovate a Bathroom in Altea?
This is the question owners ask least often and that can cause the most problems. The short answer is: it depends on the type of work, and in Altea the heritage context adds a layer of complexity.
For full bathroom renovations — including those that modify plumbing or electrical installations — the Altea Town Hall requires a Minor Works Licence (Licencia de Obra Menor, also called a comunicación de obra menor in the Valencian Community). The cost is usually under €100 and the process is straightforward if the property isn’t in a protected zone.
If the property is in the Casco Antiguo or a heritage-listed area, the process may require authorisation from the Conselleria de Cultura and timelines extend. Some works — particularly those affecting facades or structural elements — may require a project signed by an architect.
Renovating without a permit when one is required can result in fines and an obligation to restore the work to its original state. When requesting quotes, ask explicitly whether the contractor handles permit applications or whether this remains your responsibility.
How Long Does a Bathroom Renovation in Altea Take?
Timelines vary depending on the type of work and access to the property:
- Partial / cosmetic renovation: 3–5 working days
- Standard full renovation: 5–10 working days
- Full renovation with layout changes: 10–15 working days
- Design bathroom with special materials: 15–25 days (includes material delivery times)
Add to these timelines the curing time for mortar and silicone, which may require 24-48 additional hours before the bathroom can be used. In months of high humidity — autumn and winter on the Costa Blanca — these drying times extend slightly.
One factor specific to Altea: if you order imported materials or large-format catalogue porcelain, delivery times can add 2–4 additional weeks. This doesn’t increase the cost of the work, but it does extend the overall process.
How to Get a Quote and Avoid Nasty Surprises
Getting a quote in Altea has its own particular considerations. If you’re a non-resident owner and can’t be present for the visit, here are the points you can’t afford to miss.
What a bathroom renovation quote must include
A serious quote must itemise each trade separately: demolition, plumbing, electrical, floors and walls (specifying the material and price per m²), sanitaryware (with brand and model), shower screen (with dimensions and glass quality), vanity unit and taps. A lump sum without a breakdown gives you no way to compare or spot which quality decisions are being made on your behalf.
Also ask whether the quote includes:
- Waste removal and transport
- Minor works permit application
- Contingency management (what happens if a leak is found behind the wall or the electrical installation needs additional work)
- Final site clean-up
The key questions before you sign
Before committing to any contractor:
Do they have valid public liability insurance? Non-negotiable. A leak during the work that damages the neighbour below can generate claims of several thousand euros.
What guarantee do they offer on the work? Most reputable companies offer a two-year guarantee on labour. Materials carry their own manufacturer’s guarantee.
Can they manage the project if I’m not in Altea? For owners living abroad, this is fundamental. Ask whether they provide video updates, photo progress reports and who your single point of contact is throughout the project.
The VAT nobody mentions
There’s a detail that bathroom renovation articles consistently overlook, and it can significantly affect the real cost of your project: the applicable VAT rate.
Renovations on a primary residence are taxed at 10% VAT. But if the property is a second home — which is exactly the situation of many owners in Altea — the applicable rate rises to 21%.
On a €5,000 renovation, the difference between 10% and 21% VAT is €550 extra. This isn’t a cost that can be avoided, but it’s worth knowing before drawing up your total budget rather than discovering it on the final invoice.
For owners from the UK, the Netherlands or Germany: even with the higher VAT rate, a full bathroom renovation in Altea will typically cost half to a third of what the equivalent project would cost at home.
Frequently Asked Questions
How much does it cost to renovate a small bathroom in Altea?
A 3-4 m² bathroom with a full renovation — plumbing, tiling, sanitaryware and shower screen — runs between €3,000 and €4,500 with mid-to-high quality materials. If access is difficult (Casco Antiguo, no lift), add 20-30%.
Is it cheaper to renovate in Altea than in the UK or Netherlands?
Significantly cheaper. A comparable full bathroom renovation in the UK typically costs double or triple the price in Altea. Spain is the EU’s largest tile producer, labour costs on the Costa Blanca are competitive, and quality materials are widely available locally through suppliers like Leroy Merlin, Obramat and specialist tile importers in the Marina Baixa area.
Can I renovate the bathroom of my second home in Altea without being there?
Yes, but it requires choosing a contractor who offers clear remote communication: photo reports, video progress updates and a single named contact throughout the project. It’s advisable to have someone you trust in Altea who can do a walkthrough at the start and at handover.
What materials best withstand Altea’s marine environment?
Non-slip porcelain for floors, brass taps with quality finish (not chrome-washed zinc), fungicidal silicone for joints, and vanity units with moisture-resistant board. Avoid low-quality aluminium hardware on the shower screen if the property is close to the sea.
When is the best time to renovate?
Between October and February. It’s low season for the sector in Altea, companies have more availability, lead times are shorter and there’s more room to negotiate terms.
