About QuantumStone
QuantumStone is an engineered quartz surface line from Houston-based Granite Granite Inc., which opened a Tucson distribution center in 2016. Its distribution centers supply quartz countertops, cabinets, floor tiles and sinks to developers and general contractors, including multifamily, senior living and student housing projects. Colors include Calacutta, Carrara and concrete-look designs.
A supplier, not an installer
QuantumStone sells slabs. It does not cut or install countertops itself, so it will not quote you for a finished kitchen. Choose your stone here, then hire a countertop fabricator to template, cut and install it. Ask the fabricator first whether it will work with a slab you bought elsewhere; some will only cut stone from their own yard.
