Professional Hot Tubs and Premium Spas
The perfect choice: a hot tub designed for rental, with professional filtration to handle intensive use while meeting regulations.
Professional Filtration at the Core of Our Equipment
In intensive-use settings, performance does not depend on the shell alone: filtration quality plays a central role.
As a manufacturer of wood and stainless steel hot tubs and spas, we design equipment built for high guest turnover. Our solutions integrate high-performance filtration and water treatment systems adapted to demanding operating conditions.
For hotels, guesthouses, campsites, unique stays and wellness spaces
Installing a hot tub or a stainless steel spa is a real asset for enhancing a property and enriching the guest experience.
Our equipment is designed for intensive use, with high-performance filtration that keeps water clean and stable despite heavy guest turnover, as well as remote supervision designed for operators.

The heavy use of hot tubs in hotels, guesthouses, unique stays and campsites creates constraints that have nothing in common with private use.
Standard filtration may seem sufficient on paper, but it quickly reaches its limits under intensive use.

Combination of Canadian red cedar and stainless steel gives the hot tub a premium aesthetic, a warm atmosphere and a natural fit in hospitality and wellness projects.
It also offers a quieter experience than a traditional jetted spa, an advantage appreciated by both users and the establishment. It is an additional asset for preserving the comfort of the place and the peace of other guests.
Thanks to the performance of our treatment process, the water remains healthy, clear and perfectly controlled, even under intensive use.


Hot Tubs and Spas Create Value When They Are Designed for Real-World Use
For a hotel, guesthouse or unique accommodation, a hot tub or spa can become a real lever for moving upmarket. But that only works if water treatment is designed for intensive operation.
That is precisely where we make the difference, with more than ten years of experience on installations intended for professionals.
Too many market solutions rely on private-use logic or standard filtration systems.
Our approach was developed for far more demanding operating conditions.
Years of Experience
An Eco-Responsible Approach
Benefits for Operators and Guests Alike
Adapted to modern environmental expectations, our filtration technology offers an effective and sustainable response.
It combines the efficiency of UV-C, advanced oxygenation and precise filtration to deliver high-level disinfection. Ideally designed for professionals, it keeps water quality under control while minimizing chlorine use, and even allowing total elimination depending on requirements.
*Where regulations in certain countries require it, the injection of a minimum level of chlorine is automatically adjusted to the lowest level allowed by the applicable standard.

This eco-responsible approach allows our hot tubs to be both pleasant and perfectly hygienic while respecting the environment, even beyond current regulatory requirements.
Unique, their filtration and water treatment system places them above competing solutions currently available for establishments open to the public.
Their benefits are both economic and practical.
Equipping an establishment with one or more of our hot tubs allows guests to relax completely. They enjoy a sensation of weightless floating thanks to an average water depth of around one metre, unlike much shallower spas.

Daily maintenance of our hot tubs requires little effort, with more stable water and far less frequent draining than with a standard installation.
These advantages deliver excellent profitability when the hot tub is offered as a service.
Seen as a premium amenity, capable of supporting an upscale positioning and increasing the property’s attractiveness, it helps raise occupancy rates and nightly prices.
