What does it take to install a swim spa in your home?

A swim spa can transform your garden into a wellness area, but its installation takes some getting used to. Building permits, 400 V connections, reinforced concrete earthworks: every detail counts, especially in French-speaking Switzerland where the rules are strict. Thinking of installing a high-end model in your home? At Atelier Nordic, we explain what you need to know to avoid costly mistakes.

Before installing a swim spa in your home, it’s essential to check the requirements of your local authority. In Switzerland, planning permission is generally required, even for installation on an existing terrace or in a private garden. This permit governs the impact of the project on the environment, neighbors and local infrastructure, particularly for the installation of outdoor swim spas.

Local authorities often require a complete technical file: site plan, earthwork details, planned foundations, electricity, water and drainage connections. If your spa includes a heating or water treatment system, prior notice from the Environmental Department may be required. It’s best to plan ahead to avoid any delays.

In the canton of Vaud, for example, town planning regulations are strict. Any fixed swimming pool, including a swim spa, must respect a minimum distance of 3 meters from the property line. This requirement guarantees safety, accessibility and limits noise or visual nuisance for neighbors.

Cantonal standards may also impose constraints on waterproofing, thermal insulation, ventilation and wastewater management. We can help you put together a permit application, taking into account local specificities and technical requirements relating to filtration, maintenance and the possible integration of a fixed shelter.

Before installation, you need to choose a stable, level and accessible location. This guarantees smooth delivery and uncomplicated installation. The site must be carefully prepared: precise earthwork ensures stability, and a strong, flat, reinforced concrete foundation supports the weight of the spa, even when fully loaded.

We recommend that you leave a clear space around the pool to facilitate maintenance. A local permit may be required if the spa is to be installed outdoors or under a fixed shelter.

A swim spa requires reliable technical connections. The power supply must be 400 V/16 A, protected by a differential circuit breaker. This ensures the safety of the heating system, filtration pump and integrated ventilation.

A water connection is essential for regular topping-up and refilling. A nearby drain is also recommended for emptying and technical operations. We ensure that all connections comply with current Swiss standards.

We install high-performance filtration systems adapted to the volume of water. They guarantee clear, healthy water while reducing the use of chemicals. For heating, we prefer energy-efficient heat pumps.

Waterproofing is ensured by a one-piece shell or a special coating. Reinforced insulation integrated into the walls and cover reduces heat loss. Efficient ventilation of technical equipment prolongs service life and facilitates maintenance.

A swim spa represents a major investment. In Switzerland, the overall budget for purchase and installation is between CHF 25,000 and 55,000. This includes the tank, massage systems and heating, as well as the necessary earthworks and foundations.

Water, electricity and drainage connections are also included. The addition of a fixed or telescopic shelter extends the season of use, but increases the cost. We’ll help you anticipate each item for a controlled project.

Regular maintenance is essential to guarantee water quality and preserve equipment. Treatment relies on disinfectants, pH control and an efficient filtration system. These operations are simple, but must be followed rigorously.

Annual maintenance costs vary between CHF 500 and CHF 2,000. They cover treatment products, filter replacement and preventive maintenance. Good thermal insulation and ventilation help limit energy losses.

We advise you to check that your civil liability insurance covers damage related to spa use. Some companies require a declaration or authorization, particularly for outdoor installations.

We select equipment with warranties: 5 years on the structure, 1 year on electrical components. Our after-sales service remains available for any intervention, even several years after installation. Reliable follow-up ensures your peace of mind.
