Peter Klaus Hoffmann

CRESTIAL has a German Heritage, tradition of passion and love for performance.  It all began with Peter Klaus Hoffmann, the man who founded CRESTIAL and made Style, Performance and Value synonymous with it.

Hoffmann’s foray into the faucet industry began in 1979 as the Area Manager of a key German faucet brand, with sales, marketing and technical support responsibilities for the Far East/Australasia Region. Within 15 years, he and his team propelled this German brand to a market leader position in Asia.

In 1995, he decided to become independent and pursued his passion for this industry by creating his own company S U M International Pte Ltd, together with his co-founders, registered in Singapore.  By year 2000 CRESTIAL was born and is now a contender to leading brands, and a leader among generic brands.

CRESTIAL products are now well accepted in many prestigious projects in the world.
