Allstone Group is one of the few sink manufacturers that handcrafts each piece from solid blocks of natural stone. Using premium materials such as granite, Carrara marble, travertine, limestone, onyx, and soapstone-style stones, every sink is individually carved, finished, and sealed. No two Allstone sinks are ever the same. Subtle variations in veining, color and texture are part of the artistic value and natural beauty.
Many Allstone sinks arrive pre-sealed at the factory, giving homeowners a strong protective base layer from day one. Their production lineup includes farmhouse apron front sinks, undermount bowls, vessel sinks, bathroom vanities, and specialty stone pieces. Sizes range from compact 17–24 inch basins to large 36–48 inch farmhouse sinks, giving flexibility for small powder rooms, standard kitchens, and large custom spaces.
Allstone products are ideal for homeowners who want a sculptural, organic focal point rather than a mass-produced sink. The combination of artisan craftsmanship, solid stone construction, and natural variation makes each sink a statement piece that matures beautifully over time.
