SWIMMING SPAS

A swim spa is a compact pool in which a constant current allows you to swim in place—where a traditional pool would require much more length. At Treesse, this current is generated by turbines or pumps that deliver a steady flow that can be adjusted to match your pace. The range offered by Atelier Nordic consists of three models. The Aquarun, designed by Marc Sadler, is geared toward competitive swimming. The Antibes combines the swimming current with 45 hydromassage jets. The Saint-Tropez features both a swimming area and a relaxation area with 76 jets. This allows you to swim, recover, and enjoy hydromassage all in the same pool, whether indoors or outdoors.

Energy consumption varies depending on the set temperature, how often the pool is used, the quality of the insulation, and the climate. The Antibes and Saint-Tropez models come standard with a 2 x 3 kW heating system and a thermal cover that retains heat between uses.

The bill goes up in winter and during periods of heavy use, then goes down when the pool is covered and not used much, as the antifreeze system protects the circuits without using excessive amounts of energy.

No permit is required for an uncovered swim spa with a water surface area of 10 m² or less.

For swim spas between 10 m² and 100 m², a prior notice of construction is required (Cerfa form No. 13703).

A building permit is required if you add a cover that is more than 1.80 m high.

Depending on the dimensions of the model you choose, a prior declaration may be required: check with your local planning department, as local zoning regulations (PLU) vary from one municipality to another.

It all depends on your municipality and the installation method you choose. An above-ground swim spa is usually considered a movable structure and does not require any special permits. However, an in-ground installation, the construction of a concrete slab, or the addition of a cover may require a building permit.

Before starting construction, the safest course of action is to contact your local planning department to find out what regulations apply to your property.

Routine maintenance takes just a few minutes. Check the water level and balance (pH between 7.2 and 7.6), skim the waterline weekly, and add the appropriate treatment. Depending on the model, an ozonator or UV lamp continuously sanitizes the water and reduces the need for chemicals. Rinse the filters every few weeks, perform a monthly water test, and plan to completely drain the pool two to three times a year. Between swims, the standard thermal cover keeps the water clean and at the right temperature.

The Treesse line offers two configurations. The single-area model, such as the Aquarun or the Antibes, combines a counter-current swimming lane in a single pool—with or without hydromassage—and fits into compact spaces. The Saint-Tropez, on the other hand, is a dual-zone model: it features a fitness swimming area and a relaxation area with 76 jets, complete with seating for up to nine people. The right choice depends on the available space and the primary use: athletic swimming on one hand, and swimming and relaxation for the whole family on the other.

No, installation must be performed by a professional. A Treesse swim spa weighs between 800 and 1,250 kg when empty, and between 6,100 and 8,650 kg when filled, which requires a level concrete slab designed to support this load. The electrical connection must be performed by a qualified electrician, while leveling and lifting require specialized equipment. Installation and commissioning are performed by Atelier Nordic technicians. Depending on the model, an above-ground installation takes one day to complete, while an in-ground installation takes two to three days.

Built to last, a Treesse swim spa is constructed from durable materials: a galvanized steel frame on the Saint-Tropez model, a reinforced shell, a freeze-protection system, and a thermal cover that protect the entire unit throughout the seasons. Its longevity depends above all on regular maintenance and properly balanced water. The Treesse manufacturer’s warranty covers the structure for 5 years, the shell and surface for 2 years, the plumbing’s watertightness for 2 years, and other components for 2 years.

The three Treesse models feature a pool depth ranging from 137 to 142 cm, providing enough depth to swim and do water aerobics without touching the bottom. In terms of size, the Antibes remains compact at 390 x 228 cm, the Aquarun spans 510 x 235 cm to provide a true swimming lane, and the Saint-Tropez measures 596 x 228 cm, combining swimming and relaxation. This depth is easy on the joints and is suitable for both gentle rehabilitation and regular training.

The principle varies depending on the model. The Aquarun features two specialized turbines that recreate the movement of whitewater, with a 235-cm-wide channel and an interior design engineered to guide the flow. A mirror at the bottom of the pool helps swimmers monitor their form and improve their technique. In the Antibes and Saint-Tropez models, pumps generate a current that mimics natural currents. In all cases, the intensity of the current can be adjusted, ranging from a gentle swim to a sustained workout.

Yes. Treesse models are suitable for both indoor and outdoor use, in all seasons. The antifreeze system protects the circuits from freezing, the 2 x 3 kW heater maintains the swimming temperature, and the standard thermal cover reduces heat loss when it’s cold. You can continue to swim and enjoy the hydromassage even in the middle of winter, provided you keep the water clean and properly balanced.
