How Much Does It Cost to Renovate a Pool on the Costa Blanca?

Empty swimming pool during renovation with the old tiles removed and the concrete shell exposed

Many villas on the Costa Blanca were built with a pool in the 1980s, 1990s or early 2000s, and a large share of those pools are now due for attention. The cost of renovating a swimming pool in Spain can range from a few thousand euros to a figure close to a new build, depending on what is wrong and how far you want to go. This article explains where the money goes and how to read the numbers.

Start with a diagnosis, not a finish

The single most useful step is to understand the condition of the pool before choosing tiles. Two pools that look equally tired can have very different problems underneath. A proper inspection typically looks at:

  • Water loss. Losing more than a few millimetres a day beyond evaporation suggests a leak in the shell, the pipework or around fittings. A leak detection test is often worth paying for before anything else.
  • The shell. Cracks, hollow-sounding render and rust stains can indicate structural movement or corroding reinforcement.
  • Pipework. Older pools often have undersized or brittle buried pipes and few return inlets, which limits circulation.
  • The plant room. Pumps, filters and electrics may be at the end of their life or not meet current safety standards.
  • Coping and terrace. Loose or cracked coping stones and settling paving are common, especially where tree roots or poor drainage are involved.

Hard, calcareous water across Alicante province accelerates scale on tiles, grout and equipment. Salt air near the coast is hard on metal fittings and ladders. Both are part of the picture when deciding what to replace.

Indicative costs by type of work

The ranges below come from publicly available market information for Spain in 2025–2026. They help frame a budget but are not prices.

WorkIndicative range (excl. IVA)
Pool paint (prepared surface)€12–20/m² of interior surface
Reinforced PVC membrane (liner armado)~€50–70/m²
New gresite mosaic incl. removal and waterproofingroughly €70–150/m²
Re-lining an 8×4 m pool with gresiteroughly €5,500–9,000
Shell rebuild (gunite), before finish€60–120/m²
Basic renovation: re-tile, pump, filter, LED lightingfrom ~€5,000–10,000
Full renovation: new coping, steps, terrace and equipmentcommonly €20,000–60,000+
Inverter heat pump for ~40 m³ poolabout €3,500–4,500 installed

Three levels of renovation

Refresh

A refresh addresses appearance and basic function: cleaning or replacing grout, repairing isolated tiles, a new pump or filter, and LED lights in place of halogen. It suits a pool that is structurally sound and watertight. Budgets typically sit at the lower end of the ranges above.

Re-lining and equipment

Here the old finish is removed, the shell is checked and waterproofed, and a new lining is applied. It is the moment to upgrade filtration, add salt chlorination or heating, and improve the hydraulics. For a standard villa pool this often lands in the region of a basic to mid-range renovation.

Full renovation

A full renovation may include new steps or a beach entry, new coping, a rebuilt terrace, relocated equipment, new pipework and sometimes changes to depth or shape. At this level the project begins to resemble a new build in complexity, and may need a licence. Our article on what can actually be changed in a pool renovation covers the options in detail.

What moves the price on the Costa Blanca

  • Surface area, not water volume. Lining costs scale with the interior surface, including walls and steps. A deep pool with long steps has much more surface than its footprint suggests.
  • Condition of the substrate. If removing old tiles reveals weak render, it must be rebuilt before the new finish goes on.
  • Access. Many villas in Jávea, Moraira and Altea sit on terraced plots reached by steep drives. Moving rubble out and materials in by hand adds time.
  • Specification. Premium glass mosaics, large-format porcelain and natural stone coping cost considerably more than standard ranges, in material and in skilled labour.
  • Timing. Spring is peak season. Planning renovation for autumn or winter gives more scheduling flexibility, and the pool is ready for the following summer.

Running costs after the renovation

A renovation is also a chance to reduce what the pool costs to run. An older single-speed pump running eight hours a day is often one of the larger items on a villa's electricity bill in summer. A variable-speed pump, correctly programmed, can typically cut that consumption substantially. A cover reduces evaporation and heat loss, which matters both for heating costs and in towns where summer water restrictions apply. Salt chlorination and automated pH control reduce chemical purchases and the time spent on maintenance, although the chlorinator cell needs regular descaling in hard Costa Blanca water.

These upgrades add to the initial budget, but over several seasons they can offset part of it. Ask for the budget to state the expected consumption of the proposed equipment, not only its purchase price. Our guide to reducing pool energy consumption explains where the savings usually come from.

Licences and community pools

Like-for-like re-lining is often treated as minor works, but requirements vary by municipality. Changes to shape, depth, structure or the surrounding terrace may need a more formal licence. The procedure should be confirmed with the local town hall before work starts; we handle that step as part of the project.

On Costa Blanca South, many pools in Orihuela Costa and Torrevieja belong to communities of owners. Renovation there involves the community's agreement, budget approval at a general meeting and, for shared pools, specific regulations on safety and water treatment. Timelines are driven by the meeting calendar as much as by the works.

Renovate or rebuild?

When the shell is sound, renovation is almost always the more economical and less disruptive path. When there is significant structural damage, persistent leaks from multiple points or a desire to change the pool fundamentally, a rebuild can make more sense. A proper assessment, ideally with a leak test and an inspection after part of the finish is removed, is the right basis for that decision.

Questions

How much does it cost to renovate a swimming pool in Spain?

Indicatively, a basic renovation with re-tiling, new pump, filter and LED lighting starts from around €5,000–10,000 excluding IVA. Full renovations with new coping, steps, terrace and equipment commonly range from €20,000 to over €60,000.

How much does it cost to re-tile a pool with gresite?

Re-lining an 8×4 m pool with gresite, including removal of the old finish and waterproofing, is indicatively around €5,500–9,000 excluding IVA. The final figure depends on the condition of the shell and the mosaic chosen.

Do I need a licence to renovate my pool?

Like-for-like re-lining is often treated as minor works, but this varies by town. Structural changes, new shapes or terrace works may require a more formal licence.

When is the best time to renovate a pool on the Costa Blanca?

Autumn and winter usually offer more scheduling flexibility, and the pool is ready for the following season. Spring is the busiest period for builders and installers.
