Yes. It is essential to have a dedicated electrical line installed with an appropriate residual current circuit breaker. Most spas require a 230V or 380V power supply, depending on the model. Check the required power (in kW) and ask a qualified electrician to prepare the line before delivery.
Unless it’s a Plug&Play model!

A perfectly flat, stable, and weight-resistant surface is necessary. A concrete slab at least 10-15 cm thick is strongly recommended. A reinforced terrace may be suitable, but it must be approved by a building professional.

Not necessarily. Spas are usually filled using a garden hose. However, having a nearby water supply can make the filling process easier. It is also recommended to have a water drainage system (e.g., a siphon or grate) for emptying.

Allow at least 50 cm around the spa to provide easy access to all technical panels for maintenance. If the SPA is built-in, provide easily removable access hatches.

Yes, but with precautions: you need effective ventilation, a floor and wall covering resistant to moisture, and plan for water drainage in case of overflow. The electrical installation must also be suitable for a humid environment.

Not in most cases, especially for spas installed on the ground. However, if you plan a significant structure (shelter, terrace, technical room), check with your local town hall.

The installation itself (excluding preparation) usually takes between 1 and 3 hours. If you have properly prepared the electrical work, the slab, and the access points, it will be very quick.

Yes. Your presence or that of a representative is essential to indicate the exact location, check access, and confirm proper operation once the SPA is installed.
