Cast stone
Cast stone is a composite material consisting of polyester resins and natural marble chips. The process of making bathtubs from cast marble consists in combining all the components (natural component - 85%, chemical binding substances - 15%) into a liquid mass, which is poured into a mold for a bath using a special technology, and when the mass becomes hard, it is removed from the mold for further processing - the tub is ground, polished and covered with a protective coating.
