The keys to choosing the outdoor spa that suits you

1. Capacity: how many people will use your spa?

The capacity of your spa is a key factor to ensure optimal comfort and satisfy all users. Here is an overview to help you determine the right size:

• Spa for 4 people: Compact and ideal for a couple or a small family. Typical dimensions: about 1.80 m to 2.00 m in diameter.
• Spa for 5 people: More spacious, perfect for hosting family and friends during parties or social moments. Dimensions: 2.0 to 2.20 m.
• Spa for 6 or more people: For large groups or big families. Requires a substantial space with dimensions often exceeding 2.20 m.

It is also essential to consider circulation around the spa to ensure easy access and comfortable use, especially if your outdoor space is limited.

2. The type of spa: rigid, inflatable, or hybrid?

The choice of spa type depends on your budget, intended use, and frequency of use. Here is a comparison to help you understand better:

• Rigid spas: Made from composite material or acrylic, they offer excellent durability, better thermal insulation, and an elegant appearance. Installation often requires a concrete slab or reinforced base, but they guarantee superior comfort and longer lifespan.
• Inflatable spas: Less expensive, easy to move, they are perfect for seasonal or occasional use. Setup is simple, usually within minutes, but they offer less comfort and a shorter lifespan.
• Hybrid or modular models: Some products combine the advantages of both, allowing you to enjoy a rigid spa for regular use or an inflatable spa for occasional use.

3. Jet power and system

An essential feature for effective hydrotherapy, massage jets help deeply relax muscles. Here’s what should be checked:

• The total number of jets, ranging from 10 to over 100 depending on the model.
• Adjusting the power and direction of the jets for optimal customization.
• Additional options such as chromotherapy or aromatic diffusers, which enhance the relaxation experience.

A good spa should combine comfort, customization, and jet efficiency.

4. Thermal insulation and electricity consumption

Thermal insulation is crucial to reduce energy consumption and maintain a stable water temperature, especially in winter. The main elements are:

• Good thermal coverage, durable and well-fitted, to limit heat loss.
• Enhanced insulation systems around the shell and filtration system.
• A heat pump or an efficient heating system for maximum energy savings.

Depending on the region where you live, your annual electricity consumption can vary between €150 and €450, based on a cost of €0.30 to €0.40 per kWh, which is also a factor to consider when choosing your model.

Know the cost: purchase, maintenance, and operation

5. What budget to plan for buying an outdoor spa?

The cost of an outdoor spa depends on several factors: capacity, type, features, and brand. Here is an estimate to help you plan your budget:

• Inflatable spas: from €300 up to €1,200, ideal for occasional use or as a temporary solution.
• Rigid 4 to 5-seat spas: between €3,000 and €8,000, for lasting comfort and good insulation.
• Swim spas or high-end models: between €10,000 and €15,000, for advanced features like counter-current swimming, chromotherapy, or Wi-Fi connectivity.

In addition to the purchase, plan an annual budget for maintenance: water treatment, filter, parts replacement, and electricity consumption, which can range from €200 to €800 per year.

6. Optimize installation: ground preparation and electrical requirements

For full enjoyment of your outdoor spa, careful installation is essential:

• Choose a flat, stable, and durable surface, often a concrete slab or paving stones.
• Allow enough space around the spa for circulation and maintenance access.
• Ensure electrical supply complies with current standards, using a suitable residual current device and protected power source.
• Consider a shelter or canopy structure to protect your spa from the weather, especially in winter or during hot summer periods.

Maintain your spa for maximum enjoyment and longevity

7. Regular maintenance: essential steps

To ensure water quality, prevent algae or scale buildup, and extend the life of your spa, here are the main actions to take:

• Filter the water daily using the built-in system, or an external filter if needed.
• Treat the water with suitable products: chlorine, bromine, or active oxygen, according to your preferences.
• Regularly check the pH (between 7.2 and 7.6) as well as alkalinity, and adjust if necessary.
• Clean the shell and jets to prevent deposits and bacterial growth.

8. Seasonal management: enjoy all year round

If you want to use your spa even in winter, it is essential to install effective thermal insulation and cover your spa every night or during long absences. The water temperature should be adjusted for your comfort, generally between 28°C and 38°C. With proper maintenance and covering, your spa can operate year-round, offering relaxation and well-being at your fingertips, regardless of weather conditions.

Tips to optimize your investment

9. Choose models that comply with current standards

A compliant spa guarantees safety and durability. Make sure the chosen model has the necessary certifications and meets the electrical and sanitary standards in force in Belgium, France, or Luxembourg.

10. Hire professionals for installation

Proper installation ensures not only safety but also the longevity of your spa. Hire a qualified electrician for the electrical connection and specialists for installation on a suitable slab.

11. Consider the outdoor layout

Once your spa is installed, it is recommended to integrate this space into a pleasant environment: garden furniture, ambient lighting, plants, or decorative elements. Creating a relaxing atmosphere will allow you to fully enjoy your hot tub.
