With over 250 colors and patterns to choose from, we provide the flexibility to mimic natural stone while offering superior durability. Because we cast every piece to order, we can accommodate the exact sizes and unique dimensions of your project. The result is a stunning, non porous material perfect for showers, vanity tops, backsplashes, and accent walls.

Every project is unique, and our process reflects that. We hand craft our Tyvarian and cultured marble materials from scratch to meet your specific dimensions. With over 250 colors and patterns available, we can imitate high-end natural stone to perfectly match your design aesthetic.
100% Grout Free
Experience the beauty of a truly groutless bathroom. Unlike traditional tile, our large-format slabs eliminate porous seams where mold and residue hide. By avoiding grout joints, we provide a sleek, modern look that is incredibly easy to clean and stays looking new for years.
Built for Longevity
Invest in a surface that lasts a lifetime. Our specialized blend of crushed stone and resin is engineered to be rigid, dense, and highly resistant to scratches, stains, and chips. Non porous by design, our cast stone ensures your bathroom remains beautiful and water-resistant for decades.
Low Maintenance
Forget about tedious scrubbing or the need for annual resealing. Our custom cast marble is non porous and incredibly resilient, requiring only a quick wipe down with standard household cleaners to maintain its showroom shine. It’s designed to look pristine with minimal effort, saving you time for what matters most.
Incredible Value
We believe a home renovation should be a lifelong investment. While cast stone is a premium material, its durability and timeless appeal provide a "million dollar look" that significantly boosts your home's equity. You aren't just buying a countertop or shower you’re investing in a product that eliminates future repair and replacement costs.
Water-resistant
Water damage and mold growth are the enemies of any bathroom. Because our marble is non-porous, it creates an impenetrable barrier against moisture. Whether it’s for shower floors, tub surrounds, or accent walls, our materials provide a hygienic, mold-free environment that protects your home’s structure.
