Plumber in Marbella for villas, apartments and renovations
Plumbing specialists in Marbella. New installations, replacements and renovation plumbing for villas and apartments. We coordinate with other trades and manage the work for non-resident owners.
Plumbing in Marbella: what villas and apartments typically need
Marbella's residential mix includes villas with complex plumbing setups — multiple bathrooms, large kitchens, pools, irrigation systems — and older apartments with dated pipework that hasn't been updated in decades. In higher-end properties, the most common requests are replacing pipework, upgrading hot water systems, fitting new sanitaryware and taps, and adapting plumbing connections when a bathroom or kitchen is being renovated. We assess the existing installation before proposing the right approach.
What the service covers
New plumbing installations, pipework replacement, water heater and boiler installation, sanitaryware and tap fitting, and any plumbing work that forms part of a bathroom, kitchen or full property renovation. We also install or replace isolation valves, check system pressure, and locate leaks in existing installations. If you're buying a property in Marbella and want to know the state of the plumbing before committing to a renovation, we can assess it as part of the site visit.
Coordination with bathroom and kitchen renovations
When plumbing forms part of a wider renovation, we coordinate the work with all other trades — tiling, electrical, carpentry — so the pipework is correctly integrated before the finishes go in. This avoids later interventions in completed walls or floors. We work in Marbella's main private urbanisations: Golden Mile, Nueva Andalucía, Puerto Banús, Guadalmina and San Pedro. We know their access rules and work within their permitted hours. For non-resident owners, we manage access and carry out the work autonomously.
Underfloor heating and aerothermal plumbing in Marbella villas
Aerothermal heat pumps — which produce domestic hot water and feed underfloor heating and cooling circuits — are increasingly specified in full villa renovations in Marbella. These systems require the hydronic installation (underfloor pipes, manifolds, circulation pumps) to be coordinated with the electrical installation and structural works. We coordinate with aerothermal installers to ensure the plumbing infrastructure is correctly executed during the renovation phase — avoiding later interventions into finished floors or walls. If you already have underfloor heating but want to switch to an aerothermal generator, we assess the compatibility of the existing installation.
Pool and irrigation plumbing for Marbella villas
Many Marbella villas have plumbing beyond the interior: connection to the pool filtration system, automated irrigation networks, outdoor water points for garden or terrace, and sometimes outdoor showers or WCs. A full renovation is the right moment to update or extend these installations. We assess the condition of external supply pipes and distribution lines, replace deteriorated pipework and coordinate with irrigation or outdoor smart system installers when they form part of the project scope.
Plumbing on the Costa del Sol comes with a challenge you won't find in most regions: exceptionally hard water. With hardness above 30 French degrees (over 300 mg/L of calcium carbonate), limescale steadily narrows pipes, wrecks water heaters and shortens the life of taps and appliances. At Costa del Sol Reformas we treat plumbing as a full technical discipline: repiping in multilayer or PEX, non-invasive leak detection, water softeners, heaters and pressure sets, and drainage that meets Spain's CTE building code. We use our own in-house team —we never subcontract the plumber— and back every installation with a 5-year guarantee. Over 500 completed projects across Málaga and Marbella stand behind clean, measured, surprise-free work.
Repiping: from old copper to multilayer
Replacing the water system in an older home follows a disciplined sequence. We first map the existing network and measure pressure and flow; then we set the layout, pipe diameters and outlets to comply with the CTE DB-HS4 code. The material we install most is multilayer pipe (PEX-AL-PEX) from brands such as Uponor, Rehau or Standard Hidráulica: it combines the flexibility of plastic with the stability of aluminium, resists the scaling that plagues old copper, and joins with press fittings that eliminate threaded-joint leaks. For exposed runs or high temperatures we consider copper or PPR. We finish with a hydraulic pressure test before any chase is sealed —without that test, we don't sign off the job.
Finding leaks without tearing up the house
A damp patch or a spiking water bill doesn't mean tearing up half the house. We locate leaks with non-destructive methods: an acoustic ground microphone to hear the escape beneath the floor, tracer gas (a nitrogen-hydrogen mix) that surfaces at the exact break, a thermal camera to read temperature differences in underfloor heating and hot-water lines, and moisture meters to bound the wet area. This diagnosis avoids blind demolition and narrows the repair to a single opening. In limescale-heavy Costa del Sol zones many leaks start at elbows and valves clogged by scale, so when we repair we assess whether to replace the section or treat the water at source.
Hard water and softeners: protecting the whole system
Costa del Sol water is among the hardest in Spain. Above 20 French degrees softening is advisable; here it routinely exceeds 30. The most effective system is an ion-exchange water softener: resin beads capture calcium and magnesium and regenerate with brine, delivering soft water throughout the home. For simpler setups or single points we fit polyphosphate dosers, which don't remove scale but stop it adhering. We size the unit to the household's consumption and number of bathrooms, and place it after the meter with its own bypass. The payoff: heaters that don't clog, taps that last and far fewer breakdowns —a decisive upgrade in hard-water towns along the coast.
Heaters, hot water and water pressure
Domestic hot water (DHW) and pressure are the other major chapter. We choose between an electric tank, a sealed gas boiler or an aerothermal unit depending on the home; for new builds and major refurbishments the CTE code requires a renewable contribution (solar thermal or aerothermal). On pressure, the code sets a minimum of 100 kPa at taps (150 kPa at heaters) and a maximum of 500 kPa. When the supply arrives weak —common on upper floors or some urbanisations— we fit a pressure-boosting set; when it arrives too high, a pressure reducer that protects pipes and appliances. We adjust and verify with a gauge. Everything is carried out by our in-house team and covered by a 5-year guarantee.
Renovating in Marbella: local context
Renovating in Marbella is unlike anywhere else on the Costa del Sol. High-standing apartments inside gated Golden Mile communities sit alongside 600 m² villas in Sierra Blanca or Cascada de Camoján, and owners frequently live abroad, running the works in English, German or Spanish. That means premium finishes, timelines that respect the rental season, and flawless coordination with each urbanisation's community rules. At Costa del Sol Reformas we bring 500+ completed projects, our own in-house team and a 5-year guarantee, and we approach renovations in Marbella with a clear grasp of its international, premium character — from the full refurbishment of a hillside villa to fitting out a penthouse overlooking Puerto Banús.
Where we work: Milla de Oro (Golden Mile), Sierra Blanca y Cascada de Camoján, Nagüeles, Nueva Andalucía (Valle del Golf), Puerto Banús, Casco Antiguo.

Frequently asked questions
Do you carry out plumbing work in Marbella villas and apartments?
Yes. We carry out full plumbing installations in villas — hot and cold water distribution, drainage, sanitaryware, taps and water heaters — as well as targeted work in apartments, including pipework replacement and connection adaptations.
Can you coordinate plumbing as part of a bathroom renovation?
Yes. When plumbing is part of a bathroom renovation, we coordinate with the tiling, electrical and carpentry teams so everything is integrated before the finishes go in. No return visits to break open completed walls.
Do you work in private urbanisations in Marbella?
Yes. We work regularly in Marbella's gated communities. We're familiar with their access procedures and working hour restrictions, and manage all coordination with building management.
Can you manage the work if I am not in Spain?
Yes. We coordinate access, carry out the work and keep you updated. For non-resident owners, we manage the project autonomously from start to finish and confirm completion before you return.
Do you handle kitchen and bathroom plumbing in the same renovation?
Yes. If a renovation covers both the kitchen and bathrooms, we plan the plumbing across the whole project, which is more efficient and avoids duplicate access or disruption.
Can you install hydronic underfloor heating in a Marbella villa?
Yes, as part of a full renovation. Hydronic underfloor heating requires coordinated plumbing (pipes, manifolds, buffer tank) and electrical work (heat pump or boiler). We plan this from the design stage so everything is correctly integrated — not retrofitted after finishes are in place.
What plumbing problems are most common in Marbella coastal properties?
The most frequent issues are accelerated corrosion of metal pipework from coastal humidity and salt air, limescale build-up in hard-water installations, and pressure problems in multi-storey properties. In properties over 20–25 years old, we recommend checking pipework condition before closing walls during a renovation.
Do you work on pool plumbing and irrigation systems?
Yes. We work on pool supply connections and filtration plumbing, and coordinate irrigation system installations with specialist contractors. For a full villa renovation, it makes sense to review all outdoor plumbing at the same time as interior works.
