George Kefalas
The man behind the expertise
With 24 years of experience in plumbing, Georgios Kefalas is today the cornerstone of GROHE expertise in Greece. A licensed master plumber and an authorized GROHE partner since 2021, he has repaired and installed thousands of products.
“Our journey began in 2001 and continues to this day, marked by educational seminars, a teaching presence at Sivitanidios School since 2023, and ongoing support of the Greek market.”
The graduation of the first group of students from the GROHE GIVE educational program at Sivitanidios marked an emotional and historic event. With 27 graduates, the ceremony highlighted the importance of technical training and its connection to the job market. Mr. Kefalas, an active member of the program, honored the event with his presence and personally congratulated the students.
The success of the program reaffirms GROHE’s and its partners’ commitment to strengthening vocational education in Greece. The ceremony was a celebration of the future of the plumbing industry.
Students of the Sivitanidios School visited the authorized GROHE store in Athens for an out-of-classroom experience filled with hands-on learning. Mr. Kefalas, with many years of experience in the field, guided the students through the showroom, explaining the functions and technical features of GROHE’s top products.
The visit strengthened the connection between theory and practice, giving students the opportunity to see the most advanced plumbing systems and bathroom solutions up close.
During Milan Design Week, GROHE showcased its vision for the future of wellness in the bathroom through the GROHE SPA experience. Mr. Kefalas attended the presentation of new technologies that combine luxury with innovation, in a space that highlighted the connection between design and functionality.
Participation in the event offered direct exposure to global trends and technological advancements, further enriching the expertise we deliver to our clients and partners.
In Lisbon, top industry professionals gathered for the GROHE X Professional Event — a unique experience of knowledge sharing and collaboration. Mr. Kefalas took part in product presentations, discussions on sustainable practices, and workshops specifically designed for technicians and partners.
His presence at this event reinforces our team’s role as a vital link between GROHE and the Greek market, maintaining constant communication with the company’s headquarters.
The ISH international exhibition in Frankfurt is the ultimate meeting point for the world of bathrooms, water supply, and heating systems. Mr. Kefalas visited the GROHE booths as well as those of other leading brands, focusing on solutions in sustainability, technology, and design.
ISH 2025 was a source of inspiration and valuable knowledge, once again confirming GROHE’s leading presence and the ongoing need for professionals in the field to stay continuously informed.
