📋 Summary

How does a swim spa work?
The swim spa is equipped with a counter-current swimming system (CCS) that generates a powerful and steady water flow. This current allows you to swim in place, like on an aquatic treadmill. The current’s intensity is adjustable to suit all levels, from beginner to advanced swimmer.
Did you know? The term "SPA" comes from the Latin "Sanitas Per Aquam" (health through water). The swim spa takes this concept even further by adding the benefits of physical exercise to those of hydrotherapy.
📦 Types of swim spas
There are two main categories of swim spas, each with its own advantages and specific uses.
Single-zone swim spa (single basin)
Starting at €14,990The single-zone swim spa features a single basin where the swimming area and relaxation area coexist. The water is kept at an intermediate temperature (around 28-32°C) allowing both comfortable swimming and enjoying the massage jets.
Advantages:
- More affordable price
- Reduced footprint (starting from 4m long)
- Simpler installation
- Only one filtration and heating system to maintain
Disadvantages:
- Temperature compromise (neither ideal for swimming nor for massage)
- Cannot use both functions simultaneously with different temperatures
Bi-zone swim spa (double pool)
Starting at €25,000The bi-zone swim spa consists of two independent pools: one pool dedicated to swimming (temperature 25-28°C) and one pool dedicated to relaxation with massage jets (temperature 35-38°C). Each pool has its own heating and filtration system.
Advantages:
- Optimal temperature for each use
- Simultaneous use possible (one swimmer + people relaxing)
- Optimal swimming and massage experience
- Ideal for families
Disadvantages:
- Higher price
- Larger footprint (6 to 8 m long)
- Two systems to maintain
- Higher electricity consumption
💡 Our recommendation
Mono-zone: Ideal if you prioritize swimming or have a limited budget/space. Perfect for individual or couple use.
Bi-zone: Ideal for families or if you really want to enjoy both functions (sport swimming + hot spa) without compromise.
