A high-performance Glass Fiber Reinforced Concrete (GFRC) vanity countertop with an integrated ramp-style sink basin. This project uses 3/4" melamine-faced particleboard to create a highly polished, leak-proof casting mold. GFRC formulation provides extreme flexural strength, allowing a thin, elegant 1.5" profile without the weight of traditional concrete.
