This year, Mariwasa Siam Ceramics, Inc. proudly celebrates its 60th Diamond Anniversary—a historic milestone honoring six decades of beautiful, durable, and world-class Filipino home solutions.
Founded in 1966 by brothers Emerson and Edison Coseteng, Mariwasa began with a vision to deliver premium craftsmanship to local spaces. Today, in partnership with global conglomerate Siam Cement Group (SCG), we stand as the country’s most trusted partner in modern architecture and interior design.
A Heritage of Innovation and Trust
Over the last 60 years, Mariwasa has evolved from a pioneering tile manufacturer into a Total Home Solutions Provider. Our commitment to technical excellence and design depth extends across a versatile product ecosystem:
- Premium Surfaces: From timeless ceramic and large-format porcelain tile collections to our newly launched Stone Veneer Collection.
- Smart Sanitary Ware: Cutting-edge bathroom fixtures, featuring intelligent water closets and touchless wash basins designed for hygiene and water conservation.
- Professional Alignment: The preferred brand for licensed professionals, working closely with the United Architects of the Philippines (UAP) and PCAB contractors to ensure structural excellence.
Building the Future Together
“Reaching our Diamond Anniversary is a testament to the enduring trust of Filipino families, design professionals, and our dedicated partners. As we look forward, Mariwasa remains committed to sustainable innovation and elevating local spaces.”
To celebrate this milestone, Mariwasa is launching a series of anniversary campaigns and exclusive initiatives throughout 2026.
