Stonebaths Polymarble Composition
What is Polymarble?
Stonebaths polymarble is a high-performance composite material made from 50% premium limestone (calcium carbonate) and 50% high-grade acrylic resin, finished with a robust 2 mm coloured gel coat. This unique blend offers the natural look and feel of stone while delivering enhanced durability and functionality. Our products are all manufactured 100% silica free.
Why Choose Polymarble?
1. Exceptional Non-Porosity & Hygiene
Polymarble is significantly less porous than porcelain or ceramic, making it resistant to water absorption and bacterial growth. Its seamless structure means there are no joints or grout lines, which further prevents mold and bacteria buildup.
2. Superior Heat Retention
Thanks to its natural stone composition, polymarble retains heat longer than many other materials.
3. Durable & Easy Care
Polymarble is the ideal option for bathrooms offering durable and easy to maintain finishes. Read more on our Cleaning & Maintenance page
4. Lightweight with a Luxurious Stone Feel
Compared to solid stone, polymarble offers a lighter yet similarly solid feel. Being lightweight (generally between 90-180kg) reduces installation issues and structural demands without compromising on quality or aesthetics.
Industry-Backed Quality & Assurance
Stonebaths' polymarble products undergo rigorous testing for scratch resistance, stain resistance, and overall toughness to meet stringent quality standards. The result is a material that balances form and function beautifully.
In Summary
Stonebaths' polymarble offers;
- Superior heat retention for longer-lasting warmth
- Non-porous, hygienic surfaces with no grout line
- Low-maintenance durability
- A luxurious stone aesthetic with less weight and easier installation
