Setup and Installation
The Kohler K-2210-N-0 Caxton sink is designed for undermount installation, providing a clean and integrated look with your countertop. It is compatible with standard 14" x 17" countertop cutouts.
Pre-Installation Checks:
- Verify that your countertop has the correct cutout dimensions for an undermount sink.
- Ensure all necessary plumbing components (faucet, drain assembly, P-trap, supply lines) are available and compatible.
- Inspect the sink for any damage prior to installation.
Installation Steps (General Guide):
- Prepare the Countertop: Ensure the underside of the countertop around the sink cutout is clean, dry, and free of debris.
- Apply Sealant: Apply a continuous bead of silicone sealant around the rim of the sink where it will meet the underside of the countertop.
- Position the Sink: Carefully lift and position the sink onto the underside of the countertop, aligning it with the cutout.
- Secure the Sink: Use the provided mounting clips and hardware to secure the sink firmly to the countertop. Tighten the clips evenly to ensure a tight seal.
- Connect Plumbing: Install the drain assembly, faucet, and connect the water supply lines and P-trap according to their respective manufacturer's instructions.
- Test for Leaks: Once all connections are made, turn on the water supply and check thoroughly for any leaks.

Maintenance and Care
To maintain the pristine appearance and longevity of your Kohler Caxton vitreous china sink, follow these care guidelines:
- Regular Cleaning: Clean the sink regularly with a soft cloth, warm water, and a mild, non-abrasive cleaner.
- Avoid Abrasives: Do not use abrasive cleaners, scouring pads, or harsh chemicals (e.g., strong acids, alkalis, or drain cleaners) as these can damage the vitreous china finish.
- Rinse Thoroughly: After cleaning, rinse the sink thoroughly with clean water and wipe dry to prevent water spots and mineral buildup.
- Prevent Stains: Promptly wipe away any spills, especially those from acidic or staining substances like coffee, tea, or certain cosmetics.
- Protect from Impact: Avoid dropping heavy or sharp objects into the sink, which could cause chips or cracks.
Troubleshooting
This section addresses common issues you might encounter with your sink.
Issue: Water does not drain properly.
- Check Drain Stopper: Ensure the drain stopper is fully open and not obstructed.
- Inspect P-Trap: The P-trap beneath the sink may be clogged. Carefully remove and clean it.
- Main Line Clog: If other drains in your home are also slow, there might be a clog in the main plumbing line. Consult a plumber.
Issue: Water leaks from under the sink.
- Check Connections: Tighten all plumbing connections (supply lines, drain assembly, P-trap). Do not overtighten.
- Inspect Sealant: Ensure the silicone sealant between the sink and countertop is intact and providing a watertight seal. Reapply if necessary.
- Damaged Components: Inspect pipes and fittings for cracks or damage. Replace any faulty parts.
Issue: Sink appears discolored or stained.
- Cleaning: Refer to the "Maintenance and Care" section for proper cleaning procedures. Persistent stains may require specialized vitreous china cleaners.
