About Group Nivelles

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: AssentiI-DRAIN® and DzignstoneAssenti 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, they have expanded their production hall in 2018. The entire Solid Surface production has moved to the new building. The additional space was provided for their fully modernised and optimised joinery.


In terms of innovation, the organisation 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, they received the ISO 9001 quality 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 modernised and even better version of their 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.
