A countertop is part of a system. It relates to the cabinets supporting it, the appliances, the sink and the surrounding walls. Choosing a colour is only one part of the conversation.
Identify the stone and the scope
Review the proposed material, finish, thickness and included surfaces. A breakfast bar, backsplash and island may involve different decisions.
Confirm samples and the selection with the supplier. If the appearance of a particular slab matters to the design, agree on how it will be reviewed before work proceeds.
Coordinate cutouts, appliances and joints
The sink, taps and appliances affect openings and adjoining details. Supply the required documents and confirm those decisions before cutting.
Ask where joints are proposed and how the edge will be finished. Supports and any overhang require review for the actual design; an inspiration image does not replace that technical detail.
Final measurements need a prepared space
Initial dimensions help with planning. Final coordination requires checking the cabinetry and site conditions according to the installer's process.
Before confirming a schedule, establish which preparation work must be complete, how the property will be accessed and who can approve any outstanding decisions.
Make responsibilities clear
Separate the supply, transport, cutting, installation, connections and site preparation. Each item should have a responsible party and be clearly included or excluded.
Request care guidance for the installed material and finish. Comparing the same scope and specifications makes proposals more useful than comparing prices alone.
