Setup and Installation
The Duravit D-Code sink is designed for undermount installation. It is recommended that installation be performed by a qualified professional to ensure proper sealing and secure mounting.
Required Tools and Materials (Not Included):
- Sealant (silicone recommended)
- Drill (if cutting countertop or for faucet holes)
- Jigsaw or appropriate cutting tool for countertop (if not pre-cut)
- Measuring tape
- Pencil
- Safety glasses and gloves
- Faucet and drain assembly (sold separately)
Installation Steps:
- Prepare Countertop: Ensure the countertop opening is correctly sized for the undermount sink. Refer to the sink's template (if provided) or specifications for precise dimensions.
- Position Sink: Carefully position the sink upside down on a clean, padded surface. Apply a continuous bead of silicone sealant around the rim of the sink where it will meet the countertop.
- Attach Mounting Hardware: Place the sink onto the underside of the countertop opening. Secure it using the included mounting clips and screws. Tighten the screws evenly until the sink is firmly pressed against the countertop, ensuring a watertight seal. Do not overtighten.
- Install Faucet and Drain: Install your chosen faucet and drain assembly according to their respective manufacturer's instructions. Connect water supply lines and the drain trap.
- Test for Leaks: Once all connections are made, turn on the water supply and check for any leaks around the faucet, drain, and sink rim. Tighten connections as necessary.

Operating Instructions
Using your Duravit D-Code bathroom sink is straightforward. Simply operate your faucet to control water flow and temperature. The integrated overflow feature helps prevent the basin from overflowing if the drain is closed and the water is left running. Ensure the drain stopper is functioning correctly for proper water retention when needed.
Maintenance
Proper care and maintenance will preserve the appearance and functionality of your ceramic sink.
- Daily Cleaning: Wipe the sink with a dry, soft cloth after each use to prevent water spots and mineral buildup.
- Regular Cleaning: For more thorough cleaning, use a mild, non-abrasive cleaner and a soft sponge or cloth. Rinse thoroughly with water and dry.
- Avoid Harsh Chemicals: Do not use abrasive cleaners, scouring pads, or harsh chemical products (e.g., strong acids, alkalis, or bleach-based cleaners) as these can damage the ceramic finish.
- Prevent Stains: Promptly clean up any spills, especially those from staining agents like hair dyes, nail polish, or strong pigments.
- Drain Care: Periodically remove and clean the drain stopper to prevent buildup and ensure proper drainage.
Troubleshooting
Here are some common issues and their potential solutions:
- Slow Drainage:
- Check if the drain stopper is obstructed by hair or debris.
- Clean the P-trap if necessary.
- Use a non-corrosive drain cleaner if the clog persists (follow product instructions carefully).
- Leaking Around Drain or Faucet:
- Ensure all connections are tight.
- Check for worn washers or O-rings in the faucet or drain assembly and replace if needed.
- Reapply plumber's putty or sealant if the seal is compromised.
- Water Spots/Mineral Buildup:
- Regularly wipe the sink dry after use.
- Use a solution of white vinegar and water (1:1 ratio) to gently remove mineral deposits. Rinse thoroughly.
