WC lavant: between comfort, hygiene, and design

When technology elegantly enters everyday life

Combining hygiene, comfort, and aesthetics: this is the promise of the washing WC, a device that transforms the daily routine into a gentler and more precise gesture.
Thanks to its integrated water jet, it offers an incomparable feeling of cleanliness while reducing the use of toilet paper.

Often seen as a simplified version of the Japanese WC, the washing WC is now established in contemporary interiors.

At Trone, it especially marks the gateway to a more advanced vision: that of high-end Japanese WC, designed as an object of design, comfort, and absolute hygiene.

 

What is a washing WC?

The washing WC is a direct evolution of the classic WC.
It retains the same shape, the same usage logic, but adds an adjustable water jet to ensure cleaning after use.

Unlike the Japanese WC, it does not offer warm air drying, nor advanced features. It therefore does not completely replace toilet paper: it simply reduces its use by about 80%.

The principle is simple:

• an integrated nozzle delivers a precise water jet;
• settings are generally limited (fixed or no temperature, basic pressure);
• a system activated by a side button or manual control.

This technology, once considered a luxury, has become widespread as the pursuit of comfort and well-being gained importance in the home.

 

What is the difference between a washing WC and a Japanese WC?

The washing WC focuses on the essential function: water cleaning.

The Japanese WC goes much further. It offers:

• differentiated jets (rear and feminine),
• precise temperature and intensity settings,
• adjustable nozzle,
• adjustable warm air drying,
• deodorization,
• user memory,
• descaling program,
• integrated night light,
• soft closing…

In other words:
the washing WC is a first step;
the Japanese WC, like the one Trone prepares, is a complete experience.

 

The daily advantages of the washing WC

Far from a gadget, the washing WC truly improves daily hygiene and comfort.

Perfect hygiene and intimate comfort

What are the advantages of a washing WC?

• A gentler and more effective water cleaning than dry paper
• Less irritation and less direct contact
• A significant reduction in toilet paper
• An immediate sensation of freshness and cleanliness
• A simple transition to more modern uses

Water becomes a care gesture: it soothes, softens, cleans without aggression.

And even if a washing WC does not offer drying, it significantly reduces the use of paper, only used for blotting.

Economy and ecology

The washing WC does not necessarily use less water than a classic WC, but it allows to significantly reduce the use of toilet paper, whose manufacturing requires a huge amount of water and energy. This is where the real progress for the environment lies.

Maintenance is simple: cleaning with a pH-neutral product is enough to preserve the ceramic and maintain perfect hygiene.

Modern design and wall integration

The washing WC fits perfectly into contemporary bathrooms.
The future Trone model — a high-end Japanese WC — extends this philosophy with suspended lines, shiny ceramic available in white, black, cream, pink or peach, and a fluid silhouette that stands out as a design object in its own right.

 

The limitations to consider

Even if the washing WC appeals by its simplicity and comfort, a few points deserve to be known before installation.

A specific installation

The washing WC requires a water connection and, depending on the model, a electrical outlet for drying.
Its installation therefore requires some anticipation, especially during a renovation.

Once in place, the system remains discreet and reliable, with reduced maintenance.

Regular maintenance of the nozzles

How to maintain a washing WC?
Automatic rinsing (depending on the models)

• Gentle manual cleaning of the nozzle if necessary

• Cleaning ceramic surfaces with a neutral pH product

• And, on more advanced models: a descaling program, essential to guarantee jet quality over time

At Trone, the shapes are deliberately smooth and continuous to avoid deposit areas and facilitate maintenance.

Comfort adaptation according to use

If the washing WC already offers a great experience, some users seek more features — differentiated jets, precise drying, deodorization, user memory…
In this case, the transition to the Japanese WC naturally imposes itself: more advanced features, without losing ease of use.

 

The washing WC according to Trone: when technology becomes discreet

At Trone, the washing WC is not an end in itself: it represents the first step towards a modern and design hygiene experience.

But it is in the Japanese WC — which Trone will unveil in 2026 — that this vision is fully expressed: a suspended design WC, advanced features, discreet yet intuitive technology, absolute comfort.

 

Towards the future of comfort: the suspended Japanese WC

The suspended Japanese WC is the natural continuation of the washing WC.
It retains the simplicity, but adds precision, jet control, personalization, and useful technology.

Still in glossy ceramic, it combines ease of maintenance, space-saving and absolute hygiene.
It is the logical evolution of well-being in the intimate space.

In 2026, Trone will unveil its vision of the suspended Japanese WC, the result of a collaboration between Italian ceramists and French engineers.

 

Conclusion

The washing WC is no longer a luxury: it is a contemporary response to our needs for well-being, and well-beinghygiene.
It combines ease of use and elegant design, while paving the way for a new generation of more respectful, more conscious, more beautiful sanitary ware.
