Hello, I am Álvaro Ferrer, the project coordinator for TuExterior. Over the years, I have seen how the inland climate of the La Plana Baixa comarca can be both a blessing and a challenge for homeowners. With a population of approximately 26,190 residents, this area experiences intense summer heat, making the decision to install a swimming pool in Onda one of the most rewarding investments you can make for your property. Whether you are settled in the established residential areas like Sitjar Baix and Sonella, or perhaps in the newer developments of Nueva Onda and Monteblanco, my mission is to transform your garden into a private oasis. In Onda a swimming pool typically runs 8000-25000 € including local labour, depending on the complexity of the terrain and the materials chosen. We understand that residents in areas like El Salvador value both quality and durability, which is why we focus on delivering structures that withstand the specific thermal fluctuations of our region while providing a refreshing escape for your family throughout the long Mediterranean summer season.

Step 4: Installation Our specialized team carries out the excavation and build, adhering to strict safety standards and timelines, leaving you with a fully functional, beautiful pool.

Regulations and Permits in Onda

Navigating the legal landscape for construction in the province of Castellón requires local expertise. In Onda, all outdoor installations must comply with the Plan General de Ordenación Urbana (PGOU), which was established in 1998 and has been updated in accordance with the Texto Refundido de la Ley de Ordenación del Territorio, Urbanismo y Paisaje (TRLOTUP). When we install structures like pool enclosures or pergolas, we strictly follow the UNE-EN 13561 standard to ensure safety and quality.

For the swimming pool itself, the type of permit required depends on the scope of work. Most residential pools are classified as 'Obra Mayor' due to the structural excavation involved, requiring a technical project signed by an architect. However, smaller renovations or decorative surrounds might only require an 'Obra Menor' notification. It is crucial to note that specific restrictions apply if your property is located within the 'Pulmón Verde' area or the protected historic center (BIC - Bien de Interés Cultural), where aesthetic and environmental regulations are significantly more stringent to preserve the town's heritage and natural landscape.

Frequently Asked Questions

How much does swimming pool cost in Onda?
The cost generally ranges between 8,000 € and 25,000 €. This variation accounts for the difference between prefabricated polyester shells and traditional reinforced concrete (gunite) pools. In Onda, the price includes local labour, excavation in the typical clay-heavy soil of La Plana Baixa, and the filtration system. Custom features like salt chlorination or LED lighting will shift the budget toward the higher end of the scale.
Do I need a licence?
Yes, you absolutely need a municipal licence from the Onda Town Hall (Ayuntamiento). Because a swimming pool involves structural changes and excavation, it is usually processed as an 'Obra Mayor'. This requires a formal project and the payment of municipal taxes (ICIO). We can assist you in coordinating with a local architect to ensure your application meets the 1998 PGOU requirements.
How long does it take?
From the moment the first spade hits the ground, a standard concrete pool takes about 3 to 5 weeks to complete. However, the administrative process for the licence in Onda can take anywhere from 1 to 3 months depending on the workload of the municipal technicians. We recommend starting the planning process in autumn or winter to ensure your pool is ready for the first heatwave in June.
Do you cover Onda?
Yes, we provide full coverage across the entire municipality of Onda. This includes the town center and all surrounding urbanisations such as Sitjar Baix, Sonella, Monteblanco, Nueva Onda, and the rural areas near El Salvador. We are very familiar with the local geography and the specific logistics of transporting machinery to these different residential zones.
What warranty do you provide?
We provide a comprehensive warranty that covers the structural integrity of the pool shell for 10 years. Additionally, the filtration equipment, pumps, and accessories are covered by the manufacturer's warranties, typically lasting 2 to 3 years. Our installations also comply with Spanish building codes, ensuring that your investment is protected against leaks or structural shifts.
Can I install a pool in the historic center?
If your property is within the protected historic center (BIC), the process is more complex. The project must be reviewed not just by the local council, but often by regional heritage authorities. There may be restrictions on the materials used for the pool deck and the visibility of the installation from the street. We have experience navigating these specific aesthetic requirements to find a solution that respects Onda's history.
Is salt water better for the Onda climate?
Salt chlorination is highly recommended for the inland climate of Onda. The high summer temperatures can cause traditional chlorine to evaporate quickly, leading to chemical imbalances. Salt systems are more stable in the heat, gentler on the skin and eyes, and require less weekly maintenance, which is ideal for residents who want a hassle-free experience during the hot La Plana Baixa summers.
