Throughout the history of science, engineering, and great discoveries, a single brilliant insight, a simple sketch drawn in the quiet of a studio, or a bold question posed by a researcher can set off an incredible chain reaction. One such groundbreaking discovery is the Venturi effect, which allows for a powerful water suction without the use of pumps.
Roca—a global leader in the design, manufacture, and sale of bathroom solutions—has harnessed this physical phenomenon to create an innovative product.
We’ve integrated into a single unit many components and functions that for decades were separate devices. The result of this work is the groundbreaking Roca Avant toilet with a water tank built into the toilet bowl. This is made possible by technology based on the natural Venturi effect, which can be seen and experienced firsthand at the Copernicus Science Center in Warsaw. “That’s why we chose the inspiring space at the Copernicus Science Center to present our innovative solution and seamlessly demonstrate how science can be used to enhance everyday comfort,” says Joanna Dec-Galuk, Marketing Director at Roca Polska.

A Scientific Journey at the Copernicus Science Center
The event at the Copernicus Science Center attracted approximately 200 people—Roca’s customers and business partners from across Poland, as well as a large group of journalists. The film “The Road to Invention” perfectly introduced participants to the event’s theme; in it, Paweł Orleański took viewers on a fascinating cinematic journey through time, showcasing the history of groundbreaking innovations —from Leonardo da Vinci’s sketches to steam engines and NASA space rockets—leading to the discovery and practical application of the Venturi effect, utilized in Roca Avant.

The same effect was then demonstrated in a spectacular live show by the team from the Copernicus Science Center, allowing participants to see for themselves how the energy of fluid flow was harnessed.
Following this thorough scientific introduction, a video and a presentation by Roca experts—Marcin Chłodek, Product Manager, and Adam Skonieczny, Mazovia Region Manager—highlighted all the benefits of Avant technology, all encapsulated in a single unit. The experts explained in a unique way why Roca Avant is a true revolution in the market, significantly simplifying the installer’s work and bringing a new dimension of comfort to bathroom users. The grand finale of the event was the unveiling on stage of a model of the “star of the day”—the Roca Avant toilet—which captured the attention of all attendees.

Roca Avant—the only toilet of its kind
The Avant toilet, developed by Roca, is the only solution on the market in which the flush tank is built into the toilet bowl. The use of the Venturi effect allows for a powerful water suction without the need for pumps. A strong and precise stream thoroughly cleans the inside of the bowl every time. All components of the flushing system are housed in a single unit, eliminating the need for traditional installation using a frame. This significantly simplifies and speeds up installation, reduces installation costs, and provides greater design flexibility.

Roca Avant fits into any bathroom and saves space. The toilet is not only easy to install but also easy to use—the Supraglaze® coating reduces dirt buildup and speeds up cleaning, while the intuitive side-button control system ensures comfortable operation. Roca Avant is also equipped with a soft-close seat featuring a quick-release system. The patented flushing system and Roca Rimless® Vortex technology ensure quiet and efficient operation. Another advantage is water savings, thanks to the optimal and economical 4.5/3 Lflush .
All of this makes the Roca Avant, showcased at the Copernicus Science Center in Warsaw, a revolutionary solution that sets a new standard in toilet design and offers a whole new level of everyday comfort.
