Geberit keeps its Luxembourg showroom in Belval, in the Luxmill building with the entrance on Boulevard des Lumières. It displays bathroom products, including the AquaClean shower-toilet range.
The company is Swiss and a good deal older than most of what surrounds it here: it started in 1874 as a plumbing business in Rapperswil, and it still has its headquarters in Rapperswil-Jona. Today it makes installation and flushing systems, piping and bathroom ceramics, the parts of a bathroom you mostly do not see.
It is a showroom rather than a shop, open Monday to Friday with a break between 12:00 and 13:00. Contact the Belval team before coming if you want to be sure a particular product is on display.
