About the brand
Neolith is a sintered stone made by TheSize Surfaces. Clays, feldspar, silica and mineral oxides are compressed and fired, so the slab has no resin and almost no porosity.
The collections include marble looks, concrete, metal and natural stone designs. Large-format slabs mean fewer seams on long runs. Neolith suits kitchens, bathrooms, outdoor spaces and facades.
Origin: Made by TheSize Surfaces in Spain
Material: Sintered Stone

Fabrication
Our team captures your cabinets, walls and layout digitally with the StoneEx System, so cuts and seams are planned before anyone touches a slab.
You choose the exact slab at a supplier showroom. We arrange the viewing, and you approve the slab and the layout before fabrication begins.
We prepare the fabrication specs for the slab and oversee the installation, so the finished surface matches the layout you approved.
Stoneex Surfaces is listed as a Neolith by Thesize Certified Fabricator. We plan seams, edges and cutouts to follow the manufacturer's guidance.

About Neolith
Neolith is not engineered quartz, not natural stone and not a conventional tile: it is sintered stone, made by TheSize Surfaces in Castellon, Spain. Clays, feldspar, silica and natural mineral oxides are compressed under very high pressure and fired at very high temperature, fusing them into a dense, non-porous surface with no resins or synthetic binders.
Collections cover marble-inspired designs (Classtone), industrial looks (Fusion and Iron), solid colors (Colorfeel) and wood looks (Timber), from luminous Calacatta whites and dramatic Estatuario veining to iron textures and minimalist solids. Large-format slabs and several thicknesses make Neolith suitable for kitchens, bathrooms, outdoor areas, facades and furniture.
