What's Included
Your Mocoloo Undermount Bathroom Sink package includes the following:
- Mocoloo MUF1814 Undermount Bathroom Sink
- Installation hardware
- Cutout template
Setup and Installation
Follow these general steps for installing your undermount sink. It is recommended to receive the sink first and then make a precise cutout based on the provided template.
- Step 1: Prepare the Countertop. Use the provided cutout template to mark and cut the opening in your countertop. Ensure the edges are smooth and clean.
- Step 2: Apply Sealant. Apply a continuous bead of silicone sealant around the rim of the sink opening on the underside of the countertop.
- Step 3: Position the Sink. Carefully lift the sink and align it with the countertop opening from below. Press firmly to ensure good contact with the sealant.
- Step 4: Secure the Sink. Attach the provided mounting clips and tighten them evenly to secure the sink to the underside of the countertop. Wipe away any excess sealant.

Installation Tip: Leveling
Before final installation, ensure the sink is level. Use a spirit level across the top edges of the sink to check for proper alignment. Adjust as necessary before the sealant cures.

Operation
The Mocoloo Undermount Bathroom Sink features a standard 1 3/4 inch drain opening and an overflow drain. The overflow drain is designed to prevent the sink from overfilling, directing excess water into the drainpipe. The pop-up drain mechanism (if included with your faucet, not the sink) allows for easy opening and closing of the drain.

Maintenance and Care
To maintain the pristine condition of your Mocoloo porcelain sink, follow these care guidelines:
- Regular Cleaning: Wipe the sink with a dry, soft cloth after each use to prevent water spots and mineral buildup.
- Deep Cleaning: For more thorough cleaning, use a mild, non-abrasive cleaner and a soft sponge or cloth. Avoid harsh chemicals, abrasive pads, or scouring powders, as these can damage the glazed surface.
- Stain Removal: For stubborn stains, a solution of warm water and mild dish soap can be effective. Rinse thoroughly after cleaning.
- Avoid Impact: While durable, porcelain can chip or crack under heavy impact. Avoid dropping heavy objects into the sink.

Troubleshooting
If you encounter any issues with your Mocoloo Undermount Bathroom Sink, consider the following common solutions:
- Leaking around the rim: Ensure the silicone sealant was applied correctly and evenly during installation. Reapply sealant if necessary. Check that mounting clips are tightened securely.
- Slow drainage: Check the drain for any blockages. Ensure the pop-up drain mechanism is functioning correctly and not obstructing water flow.
- Water spots/mineral buildup: Regular wiping with a dry cloth can prevent this. For existing buildup, use a vinegar solution or a specialized mineral remover, followed by thorough rinsing.
For persistent problems, contact Mocoloo customer support or a professional plumber.
