Our Products
At Bellport Premium Stoneworks (formerly Bellport International), we specialize in custom stone products for kitchens, baths, and more-all crafted and installed from our base in Bellport, NY. With over 700 slabs on-site in our showroom, you can select from one of the largest local inventories of natural and engineered stone, then have it fabricated and installed to your exact specifications.
Custom Stone Countertops
Our core product is custom stone countertops for kitchens, bathrooms, bars, laundry rooms, and more. We offer a wide range of materials, including:
Granite
Marble
Quartz
Quartzite
Porcelain
Dekton, Neolith, and other premium surfaces
Every countertop is templated, cut, edged, and polished in-house, then installed by our experienced team. From simple straight runs to complex islands and waterfall edges, we build countertops that are as durable as they are beautiful.
Custom &
Patented Shower Bases
We are known for our custom and patented shower bases, designed to bring both function and luxury to your bathroom. These bases are:

This integrated approach ensures your cabinets, stone, and hardware all come together as a cohesive design.
