A private pool is one of the reasons you bought on the Costa del Sol in the first place. But if you live in Manchester, Hamburg, Amsterdam, Lyon or Gothenburg and visit a few weeks a year, that blue rectangle is not a luxury you enjoy passively — it is a small piece of technical equipment that needs chemistry, electricity and regular hands to stay safe and clear. Leave it for a fortnight in a Mijas July and you can come back to a green swamp that costs hundreds to recover.
This guide sets out what pool maintenance genuinely costs in Málaga province in 2026, what a good contract includes, the salt-versus-chlorine question, winterising, and why holiday-let pools always need more attention than your own.
Answer capsule: A standard 8 x 4 m Costa del Sol villa pool costs roughly 70 to 140 EUR per month on a year-round weekly-summer contract with chemicals included, or about 900 to 1,700 EUR per year. Add electricity (180 to 290 EUR), water top-ups, and seasonal opening or winterising (100 to 175 EUR each) and the realistic all-in figure is 1,300 to 2,900 EUR per year. Holiday-let pools cost more because they need extra visits and documented water testing.
What a Maintenance Contract Costs in 2026
Almost every absentee owner ends up on a fixed monthly contract — it is by far the most sensible arrangement when you are 2,000 kilometres away. For a typical 8 x 4 m villa pool on the Costa del Sol:
- Weekly service, high season (May to October): 70 to 140 EUR per month, chemicals included. Most owners pay around 90 to 100 EUR.
- Fortnightly or reduced winter service (November to April): roughly 40 to 70 EUR per month.
- Year-round averaged contract: most firms quote a single flat monthly fee — typically more visits in July and August, fewer in winter — billed the same every month for budgeting ease.
Prices skew higher in Marbella, Sotogrande and the upper end of Estepona, where villas, larger pools and demanding standards are the norm. In Fuengirola, Benalmádena and Torremolinos, where apartment-block and townhouse pools dominate, you will find more competitive rates.
A standard contract should include: surface skimming, brushing the walls, vacuuming the floor, emptying skimmer and pump baskets, testing and correcting pH and chlorine on every visit, routine chemical top-up, and a filter backwash. Get this list in writing.
What Is Usually Extra
The monthly fee covers routine work. These items are almost always billed separately, so budget for them:
- Shock chlorination after a storm or an algae bloom: 30 to 50 EUR per treatment.
- Filter sand change (every 3 to 4 years): around 350 to 450 EUR including labour.
- Pump or motor replacement (every 8 to 12 years): 300 to 700 EUR installed.
- Salt cell replacement (every 5 to 7 years): 420 to 900 EUR.
- Spring opening and autumn winterising: 100 to 175 EUR each if not bundled into your plan.
Salt vs Chlorine: Which Makes Sense
This is the question almost every new owner asks. Both systems sanitise the water with chlorine — the difference is how that chlorine is produced.
Traditional chlorine uses tablets or liquid you (or your service) add manually. Lower upfront cost, but annual chemical spend runs 200 to 400 EUR, and the water can smell and sting eyes if dosing drifts.
Salt chlorination dissolves ordinary pool salt in the water and a small electrolysis cell converts it to chlorine automatically. The cell costs 600 to 900 EUR to fit, but annual chemicals then drop to 100 to 180 EUR — mostly a sack of salt and some pH adjuster. The water feels softer, with no chlorine smell.
For an absentee owner who uses or lets the pool more than four months a year, salt usually pays for itself within four to six years and gives more stable, lower-maintenance water between visits. The trade-off: the cell is a wear part that eventually needs replacing, and running it at the wrong salinity burns it out early.
Electricity: the Line Owners Forget
The filter pump is the quiet cost. A standard fixed-speed pump runs 8 to 12 hours a day in summer and 2 to 4 hours in winter, adding 180 to 290 EUR a year at 2026 Spanish electricity prices. A modern variable-speed pump cuts that to 60 to 100 EUR — one of the best efficiency upgrades you can make, paying back in a few years. Running the pump in cheaper off-peak hours saves a further slice.
The Intense-Summer-Use Factor
Andalusian summers are the real driver of cost. From June to September, sustained heat above 30 degrees, strong UV, dust and the Saharan calima all attack water balance. Chlorine burns off fast in the sun, evaporation drops the water level daily, and a pool that sat clear all spring can turn cloudy within days of a heatwave.
This is why Costa del Sol contracts step up to two visits a week in July and August. It is also why the cheap-looking fortnightly contract is a false economy in high season for any pool that is actually being used: the gap between visits is exactly when algae takes hold, and the recovery treatment can cost 300 EUR or more — far above what you saved.
Why Holiday-Let Pools Need More
If you let your property to tourists — registered as a VFT (Vivienda con Fines Turísticos) with the Registro de Turismo de Andalucía (RTA) under the Junta de Andalucía — your pool carries extra obligations and extra wear.
A holiday-let pool with back-to-back guests through summer sees far heavier use than a family’s own pool: more sun cream, more debris, more bathers loading the water. It needs more frequent visits, faster fault response, and you should keep a documented log of pH and chlorine readings — your insurer can ask for it after a claim, and an unsafe pool is a real liability with paying guests on site. Many managers therefore put holiday-let pools on a premium visit schedule, which costs more than a private contract but protects your licence, your reviews and your peace of mind. A green pool in a guest photo is a refund and a one-star review.
A Simple Owner’s Checklist
Even with a contract, a few habits protect you as an absentee owner:
- Get the included tasks and the extra-charge items listed in writing before signing.
- Confirm the summer visit frequency steps up to twice weekly in July and August.
- Ask for dated photos or a short report after each visit while you are abroad.
- Agree a spending ceiling above which they must call you before repairs.
- Fit a cover — it cuts evaporation by around 90 percent and chemical use by a third.
- Keep a water-test log if you let the property, and check local drought rules before any full refill, as Nerja and several inland municipalities have restricted pool filling in recent dry summers.
Annual All-In Figure to Budget
For a standard 8 x 4 m private villa pool in 2026, budget 1,300 to 2,900 EUR per year all-in: contract, chemicals, electricity, water and a share of equipment replacement. Larger or heated pools, and busy holiday-let pools, push towards 3,000 to 4,500 EUR. Use the lower end only if you genuinely do some work yourself — which, for an owner abroad, rarely holds.
