Installation Guidelines
The Rohl Shaws Classic UM3018WH is an undermount sink. Professional installation is recommended to ensure correct fitting and sealing.
Important Note on Dimensions: Due to the handmade construction by skilled craftsmen, dimensions of fireclay sinks may vary by +/- 2%. It is strongly recommended that the cabinet maker waits until your sink is delivered and physically measured before fabricating the cabinet or countertop cutout. No template is provided or available due to these inherent variations.

Ensure adequate support for the sink's weight (approximately 155 pounds) plus the weight of water and contents. Consult a professional for appropriate cabinet reinforcement if necessary.
Usage and Operation
This single bowl kitchen sink is designed for general kitchen tasks such as washing dishes, preparing food, and other household chores. The central drain location facilitates efficient water drainage.
For optimal performance, ensure the drain is clear of large food particles before running water, especially when using a waste disposal unit.

Maintenance and Care
To maintain the pristine condition of your Rohl Shaws Classic fireclay sink, follow these care instructions:
- Daily Cleaning: Wipe the sink with a dry, soft cloth after each use to prevent water spots and mineral buildup.
- Regular Cleaning: For general cleaning, use a mild soap or non-abrasive cleaner with a soft sponge or cloth. Rinse thoroughly with water and dry.
- Stain Resistance: The glazed surface is resistant to acids and alkalis. However, avoid prolonged contact with harsh chemicals or abrasive cleaning agents, which can damage the finish over time.
- Avoid Impact: While fireclay is durable, avoid dropping heavy or sharp objects into the sink, as this can cause chipping or cracking.
- Heat Resistance: Fireclay can withstand temperatures up to 2700 degrees Fahrenheit, making it highly resistant to heat from hot pots and pans.

Troubleshooting
- Slow Drainage: If you experience slow drainage, ensure the drain opening is clear of debris. The sink features a standard 3 1/2-inch drain opening; ensure your waste disposal unit or basket strainer is compatible and properly installed.
- Water Pooling: Fireclay sinks are known for their flat bottoms, which can sometimes lead to minor water pooling or requiring manual assistance to move waste towards the drain. This is a characteristic of the design and not a defect. Regularly wipe down the sink to prevent mineral buildup in these areas.
- Surface Discoloration: While resistant to stains, certain highly pigmented foods or liquids left for extended periods may cause temporary discoloration. Clean immediately with a mild abrasive cleaner designed for ceramic surfaces.
