How To Install Kitchen Cabinets

Pre-installation Preparations
‌Verify site conditions: Ensure kitchen wall tiles, floor tiles, and ceiling installations are complete, and that plumbing and electrical modifications have passed inspection.
‌Site protection: Lay protective sheeting (such as striped tarpaulin) on the floor to prevent dents or scratches to finished surfaces during installation.
‌Material inspection: Unpack and inspect all panels and hardware for damage; take photos of any issues as evidence and contact the supplier immediately for replacements.
‌Confirm key details: Mark the routing of concealed plumbing and electrical lines on the walls; verify the exact dimensions of the range hood, sink, and cooktop to ensure cutouts are positioned correctly later.

Base Cabinet Installation Steps
Clean the floor in the installation area and use a spirit level to check the overall floor levelness.
Arrange cabinets according to the layout: for L-shaped layouts, extend outward from the corner; for U-shaped layouts, align the center cabinet first before extending to both sides.
Level each cabinet individually using the adjustable legs at the base to ensure the entire unit is level and not tilted.
Fasten adjacent cabinets together using at least four specialized connectors to ensure a tight, secure fit without looseness.
Cut openings in the sink cabinet's bottom panel to accommodate plumbing; make the cutout diameter 3–4 mm larger than the pipe and seal the edges with sealing strips.
