SFA's Saniwash washlet-dryer: perfect hygiene, optimal comfort, savings, respect for the environment and an attractive price

Washlet-drying toilet: how does it work for sanitary hygiene?

A washlet-dryer is based on a construction system incorporating a washing nozzleIt features a hot air drying system and electronic controls. The user initiates a complete cycle including washing and drying, thus reducing the need for paper.

This principle is in line with the hygiene requirements defined by modern sanitary facilities, particularly in public access buildings (ERP) or adapted housing. The standard EN 997relating to toilet bowls and their flushing performance, specifically addresses hydraulic performance.

In the case of Saniwash, the system offers:

• un anal and intimate washing with jet oscillation,
• several levels of pressure and temperature (32 to 42 °C),
• Adjustable drying up to 52°C.

"The concept of a washlet-dryer generates savings in both water and toilet paper."

A fluid engineering firm or a plumbing installer usually intervenes to check compatibility with the water network and the electrical supply.

Water consumption and environmental impact of toilets

One of the technical arguments rests on the reduction in overall consumptionA complete Saniwash cycle uses between 3,5 and 4,6 liters of water, including washing and flushing.

For comparison:

• a roll of toilet paper requires between 168 and 178 liters of water are needed for its production.,
• a standard toilet flush uses between 6 and 9 liters per use.

In France, the average annual consumption is estimated at 103 rolls per person. This figure highlights the benefits of washing with water in a broader context. responsible resource management.

"The WWF estimates that 27,000 trees are cut down every day for the production of toilet paper."

However, a nuance must be made: the environmental gain depends on the actual uses and frequency of use of electrical functions (heating, drying), which influence energy consumption.

Comfort and accessibility in housing

Beyond hygiene, the washlet-dryer addresses issues of ease of use and accessibilityIn a home, it can contribute to maintaining people in their own homes, particularly for the elderly or those with reduced mobility.

The Saniwash incorporates several features:

• heated seat (up to 38°C),
• remote control with user profiles,
• massage function
• Deodorization via activated carbon filter.

Automatic opening via presence sensor and soft-close mechanism contribute to safe operation. These features are part of a design approach that...housing adaptation, in line with the recommendations of the National Housing Agency (Anah) for autonomy.

A plumber or a general contractor can integrate this type of equipment into a bathroom renovation project.

Installation and compatibility with existing systems

The Saniwash can be installed in new construction as well as renovations. It is compatible with wall-hung toilet solutions equipped with macerators, particularly in configurations where gravity drainage is limited.

In this context, it can be associated with:

• a wall-mounted frame,
• an integrated grinding system,
• a secure power supply (standard) NF C 15-100 (for damp rooms).

This compatibility facilitates its integration into existing housing without major modifications to the drainage network.

A concrete example: in an old apartment without a suitable gravity drain, an installer can combine a wall-hung toilet with a macerator and a washlet toilet to optimize space and sanitary performance.

Maintenance, upkeep and technical limitations

The equipment incorporates several functions that facilitate maintenance:

• self-cleaning nozzles,
• UV sterilization of the toilet bowl,
• Descaling cycles with LED indicator.

These devices meet the durability requirements for sanitary equipment, but require regular monitoring. Water quality (limescale) can particularly influence the frequency of maintenance.

One operational limitation must be highlighted: the presence of electronic components and heating elements requires a reliable power supply and can generate higher maintenance costs than a conventional toilet.

"Automatic nozzle cleaning and UV sterilization contribute to equipment maintenance."

Finally, the price positioning below 1,000 euros makes this type of solution more accessible, although the overall cost depends on installation and technical adaptations.

The shift in sanitary equipment towards hybrid solutions like the washlet-dryer reflects a transformation in usage patterns. However, their suitability depends on the installation context and user habits, balancing hygienic performance, comfort, and resource efficiency.
