Our Story
Polystone (S) Pte Ltd is built on nearly 50 years of heritage in natural stone craftsmanship. Founded by Mrs. May Koh, and now led by her daughter Patrina Koh, we have dedicated ourselves to restoring, sourcing, and applying the world’s finest stone with artistry and care.
What began as a family passion for marble, granite, quartzite, onyx, lava stone, sandstone, limestone, and semi-precious decorative stone has grown into a trusted name in both Singapore and overseas projects. From traditionally aged mosaic restoration to modern architectural installations, our work reflects a deep respect for stone’s natural beauty and enduring strength.

Our Legacy
Over the decades, Polystone has contributed to prestigious projects in Singapore and abroad, earning the trust of architects, designers, and institutions. Today, we continue to combine tradition with innovation — passing down knowledge while staying current with modern design needs.
Our Commitment
At Polystone, we believe stone is more than a material — it is heritage, art, and legacy. That’s why we are committed not just to delivering projects, but also to guiding our clients with the right knowledge, proper application, and lasting care, ensuring every piece of stone continues to inspire for generations.
Working with Polystone was an exceptional experience. Their collection of marble and natural stone is remarkable, but what truly stands out is their understanding of how stone transforms a space. The team guided us through every detail, ensuring the final installation felt both timeless and sophisticated.
