The frequent use of hot tubs available at hotels, cottages, campsites, and other accommodations generates

significantly more upkeep compared to those linked to private use.

This means ordinary filtration will not do the job.

Pro System


Canadian red cedar wood is visually pleasing and smooth to the touch. This noble material invites you to commune with the surrounding environment, whether indoors with background music and subdued lights, or outdoors with fresh air and the whispers of nature offering a breathtaking view of a blue or starry sky. In these moments of relaxation, silence is gold.

This is an added advantage of our hot tub over other hot tubs and spas whose jet machines are just as noisy for the user as for other clients of the establishment. Thanks to its quiet power and patented injection system, our treatment process ensures that the water is perfectly healthy and clear at all times, even with heavy use.

Hot tubs, spas, and jacuzzis are a major asset for any places of accommodation
who wish to offer first-class comfort to their customers.

While a hot tub is ideal for high-end accommodations, it also requires precise and rigorous maintenance.

However, many companies offer a poorly adapted water treatment system like that of a swimming pool. Some even go so far as to exempt themselves from any type of water treatment!

For 8 years, we have been implementing a water treatment unit with an eco-responsible approach.
This approach is carried out in close collaboration with our partners who offer a variety of unusual accommodations.
Innovative in several ways, this filtration system meets the needs of professionals who are subject to very strict hygiene standards.


 An eco-responsible approach

Product benefits for both operators and customers.

Our water filtration system is the perfect answer to the ecological aspirations of today.
No expensive and harmful chemicals are needed to keep the water pure.

Thanks to a customized UV-C filtration with a patented ozone injection system, the water is subjected to a complete sterilization of the highest quality, without the addition of chlorine* or any other product.

*where required by the regulations of certain countries, the minimum chlorine injection is automatically adjusted to the minimum rate of the standard in force

The eco-responsible approach allows our hot tubs, spas, and jacuzzis to be both pleasant and perfectly hygienic while respecting the environment, even beyond what current regulations require.

Our unique filtration and water treatment system sets us apart from our competitors currently on the market for businesses and establishments open to the public. The advantages are both economical and practical.

Equipping your establishment with one or more of our hot tubs allows customers to completely relax. They will experience a feeling of floating in weightlessness, thanks to a water level reaching one meter on average – unlike Jacuzzis which are much shallower.


The maintenance of our hot tubs, spas, and jacuzzis requires very little: little time, no chemical products, and no daily cleaning or water change.

Significant savings are made in terms of consumables and maintenance.

These advantages lead to excellent profitability for your hot tub, which is considered a service.

As a high-quality, environmentally-friendly service, your hot tub will lead to an increase in the rate of occupancy and the price per night.

Our offer is simple: order our hot tub and filtration system today to offer your customers the gift of relaxation as soon as possible.
