Gandía beach: thousands of apartments with 1980s-90s bathrooms urgently needing renovation
The Playa de Gandía and the Puerto are one of the most established second-home destinations in the Valencian Community. A long coastal strip of apartment blocks built between 1970 and 2000, mostly owned by Valencian families who use them in summer and keep them closed the rest of the year.
The marine damp factor: the coastal-specific issue
First and second-line beach apartments in Gandía have a silent enemy: saline marine damp. This manifests in several ways:
- Wall cladding: porous ceramic tile (common in 1980s flats) absorbs ambient moisture and salt, accelerating joint deterioration and encouraging black marks and efflorescence (white salt deposits).
- Plumbing: bare copper pipes in very humid zones develop external pitting corrosion.
- Fixtures: marine salt air attacks chrome and galvanised finishes.
Recommended materials for Gandía beach:
- Rectified porcelain with minimal joint (1-2 mm)
- PVD-finish taps (Grohe and Hansgrohe have PVD lines) — more corrosion-resistant than standard chrome
- Anodised aluminium shower screen profiles (not lacquered)
- Neutral high-quality silicone sealant (Dow Corning, Sika Sanisil)
When to do the work: autumn and winter are the only real options
In Gandía beach, the apartment is occupied from May to September and completely empty from October to April.
The ideal window: November to February. The apartment is completely free, tradespeople have availability, and there is enough time to have the bathroom ready before Easter.
The most common mistake: the owner decides in August and expects to start in September. By September the waiting list is already long. Planning should happen in spring for autumn-winter works.
Managing the project without the owner present
In Gandía beach, it is normal for the project to happen in winter while the owner is in Valencia. This requires:
- Key management with a trusted local contact
- Daily photographic progress report (start and end of each day, critical points: plumbing before closing, shower waterproofing)
- Material selection by video or digital showroom
- A final in-person inspection with the company present
