Craftsmanship since 1865

Dutch craftsmanship

WISA was founded in 1865 by Wolf Joseph Stokvis, owner of W.J. Stokvis Fabriek van Metaalwerken (Factory for metal processing) in Arnhem, The Netherlands. The company used the name WISA, after the initials of his son Willem Isaac Stokvis and the domicile Arnhem. Since the beginning the company engaged in the production of products for the water regime, like supply and discharge products and tabs.

In 1903 the first cast iron cistern was produced. In 1912 the company was granted the predicate 'Royal'. With exception of a recess during WO II, the cast iron cistern is produced for over fifty years. 

After the war, a start was made with the processing of plastics. Finally, this lead to the convertion of the total production to plastics. In 1983, the trademark WISA became the company name. 

Nowadays WISA is a growing Dutch producer. We translate our rich history to todays demands. Design en water saving are main themes and above all, quality and installation ease are our motive.
