Kitchen base cabinets are installed before flooring. The flooring runs to the cabinet toe kick — not underneath the cabinet boxes. This is correct for several reasons: cabinets bear significant weight and should sit on the structural subfloor; if cabinets are ever replaced, flooring runs cleanly under the new toe kick without exposed cuts; and floating flooring that runs under cabinet boxes can compress or shift under load over time. Wall cabinets can be installed in either order. RainFire Builders sequences cabinetry and flooring correctly as standard practice on every project — it is never a debate on our job sites.
