About Us

Group Nivelles is a family business that was founded in 1994 in Sint-Truiden. Originally the company’s main activity was importing and selling bathroom furnishings. In the meantime, GNI has grown to become a manufacturer and distributor of bathroom furnishings, stone and synthetic showers, basins and drainage channels.

Today, GNI embraces three key brands: Assenti, I-DRAIN® and Dzignstone. Assenti represents the high end of the market in bathroom furnishings and wash basins, I-DRAIN® covers shower drainage. The brand Dzignstone includes products such as shower basins and wall panels in multiple high-quality materials: Solid Surface, composite and natural stone. GNI believes that the three foundations of a strong and successful business are entrepreneurship, innovation and internationalization. In order to keep up with the rising demand for Solid Surface, we have expanded our production hall in 2018. The entire Solid Surface production has moved to the new building. The additional space was provided for our fully modernized and optimized joinery.


Group Nivelles strives for professional product commercialization in all of its activities to ensure continued growth and to strengthen its market position. Group Nivelles hopes to achieve an annual growth percentage of 10 to 15 percent. Group Nivelles will achieve growth through innovation and internationalization. We act from social involvement. Family feeling, job satisfaction, enthusiasm, sincere appreciation, focus on results ... That's what we stand for. We want to give sufficient opportunities and space to all employees, including those who have a bit more difficulty on the labor market. This happens in an open culture but with clear agreements so that everyone knows what is expected of them. Quality results remain important.


In terms of innovation the organization won a prize with I-DRAIN® in 2010 in the VOKA innovation awards and was also the winner of the innovation prize in the French Archivision in 2011. Meanwhile I-DRAIN® is a strong contender on both the national and international market. In 2014, we received the ISO 9001quality label, and in 2016 the ‘LGA tested’ certificate for tested and monitored safety and quality. In 2017, Group Nivelles introduced her improved siphon: the I-DRAIN® PRO. This is a modernized and even better version of our classic product, the I-DRAIN® ONE. In addition the I-Drain Liquid and I-Drain Smart are internationally marketed since 2017. Group Nivelles will keep on working on and investing in innovations in the future.
