6.2 Installation Steps
- Prepare Countertop: Place the sink upside down on the reverse side of your countertop. Carefully outline the sink's perimeter to mark the opening for cutting.
- Cut Countertop Opening: Using a jigsaw or appropriate cutting tool, carefully cut along the marked outline. Ensure the edges are smooth.
- Apply Sealant: Apply a continuous bead of silicone sealant around the rim of the sink opening on the underside of the countertop.
- Position Sink: Carefully lift the sink and align it with the opening from underneath the countertop. Press firmly to ensure good contact with the sealant.
- Secure Sink: Attach mounting clips (if applicable) to secure the sink to the countertop. Tighten the clips evenly until the sink is firmly in place. Do not overtighten.
- Final Placement: Allow the silicone sealant to cure completely according to the manufacturer's instructions before connecting plumbing or using the sink. Wipe away any excess sealant.

7. Operating
Once installed and plumbing connections are complete, the sink operates like any standard bathroom lavatory. Ensure the drain stopper (if installed) is functioning correctly to hold or release water as needed. The integrated overflow helps prevent water from spilling over the rim if the sink is overfilled.
8. Maintenance
Regular cleaning will maintain the sink's appearance and hygiene. The smooth, glazed ceramic surface is designed for easy upkeep.
- Daily Cleaning: Wipe the sink with a damp cloth and mild soap after each use to prevent water spots and soap scum buildup.
- Deep Cleaning: For more thorough cleaning, use a non-abrasive bathroom cleaner. Avoid harsh chemicals, abrasive pads, or scouring powders, as these can damage the glaze.
- Overflow Maintenance: Periodically clean the overflow channel to ensure it remains clear of debris.
- Stain Prevention: Promptly rinse away any substances that could stain the ceramic, such as hair dyes or strong cleaning agents.
