On the French Riviera, the mild climate makes it possible to use the outdoor spa virtually year-round. The view, the stars, and the scents of pine trees or fig trees transform every soak into a moment of escape. Installation is relatively simple: a concrete slab, electrical and water connections, and the spa can be set up in just a few hours.

In terms of cost, an outdoor spa is generally more affordable: noarchitectural integration work is required, there are no ventilation issues, and there are no additional costs associated withwaterproofing the enclosure. This is the option chosen by most homeowners when installing a spa for the first time.

An indoor spa —located in a dedicated room, a sunroom, or a wellness area —offers unparalleled comfort in the winter: no wind, no chill when stepping out of the bath, and the ability to schedule use at any time. It is also the preferred solution for properties that are highly exposed (to wind or view from the outside) or for regular therapeutic use.

On the other hand, installation is more demanding: a waterproof floor, controlled mechanical ventilation to remove moisture, enhanced wall insulation, and condensation management. Without these precautions, there is a real risk ofchronic moisture and material deterioration.

A spa heated to 38 °C evaporates several liters of water per day. Indoors, this moisture must be removed using a dual-flow mechanical ventilation system designed for damp rooms, ideally paired with a dehumidifier. Otherwise, condensation on windows, mold in corners, and damage to wood and plaster will appear within a few months.

POOLRITUAL works with fluid dynamics engineering firms to properly size the ventilation system for each indoor spa project—this is a technical matter that leaves no room for amateurism.

Regardless of the location, several factors shape the experience: number of seats (from 2 to 8), number and type of jets (quality over quantity), heating power and type, water treatment system (bromine, chlorine, or, more recently, ozone and UV), quality ofthe tub’s insulation, and the pump’s noise level.

Leading brands —Jacuzzi, Caldera, Sundance, HotSpring, and Aquavia—offer widely varying levels of quality. The initial cost and ongoing costs (annual electricity consumption, lifespan) must be weighed together.

Outdoors, the challenge is to blend the spa into its surroundings: a wooden deck, integration into a stone surround, a pergola, or a screen of plants. A spa simply placed on a deck never achieves the desired effect.

In interior design, integration is achieved through materials (premium wood, mosaic, marble), lighting, and the creation of a true wellness experience: shower, changing room, and sometimes a sauna or steam room as complementary features. It is in projects like these that POOLRITUAL truly showcases its expertise in wellness design.

A spa requires specific maintenance: weekly water testing (pH, disinfectant, hardness), filter cleaning every 15 days, and a complete drain 3 to 4 times a year. Although the volume is small, the high temperature and the concentration of bathers make the water chemistry sensitive.

POOLRITUAL includes spa maintenance in its customers’ service contracts, with dedicated service visits, supplies, and regular inspections. This continuity of service is invaluable—a poorly maintained spa is immediately noticeable and compromises its usability.
