4. Setup and Installation
This section outlines the general steps for installing your wall-hung hand rinse basin. Professional installation is recommended.
4.1. Tools and Materials Required (Not Included)
- Drill and appropriate drill bits
- Level
- Measuring tape
- Pencil
- Adjustable wrench
- Sealant (silicone)
- Faucet, drain assembly, and P-trap
4.2. Installation Steps
- Prepare the Wall: Ensure the wall where the basin will be mounted is structurally sound and capable of supporting the weight. Mark the desired height for the basin. Refer to the dimension diagram for recommended mounting points.
- Mark Drilling Points: Using the provided template or by carefully measuring the basin's mounting holes, mark the drilling points on the wall. Use a level to ensure accuracy.
- Drill Holes: Drill holes at the marked points using an appropriate drill bit for your wall type. Insert the wall plugs (if provided or required).
- Install Mounting Bolts: Secure the mounting bolts into the wall plugs, ensuring they are firmly seated and protrude sufficiently to attach the basin.
- Install Faucet and Drain: Before mounting the basin to the wall, install the faucet and drain assembly into the basin's pre-drilled holes. Follow the manufacturer's instructions for these components.
- Mount the Basin: Carefully lift the basin and align its mounting holes with the bolts on the wall. Slide the basin onto the bolts. Secure it in place with washers and nuts, tightening them evenly until the basin is snug against the wall. Do not overtighten.
- Connect Plumbing: Connect the hot and cold water supply lines to the faucet. Connect the drain assembly to the P-trap and then to the wall drain pipe. Ensure all connections are hand-tightened, then use a wrench for a final quarter-turn, being careful not to overtighten.
- Seal Edges: Apply a bead of silicone sealant around the edges where the basin meets the wall to prevent water ingress. Smooth the sealant for a clean finish.
- Test for Leaks: Turn on the main water supply and check all connections for leaks. Run water through the faucet and observe the drain for any drips.

5. Operating Instructions
The GROHE BAU Ceramic Hand Rinse Basin is designed for standard bathroom use. To operate:
- Turn the faucet handle to control water flow and temperature.

- Ensure the drain stopper (if installed) is open when not filling the basin to allow water to flow freely.

6. Care and Maintenance
Proper care will ensure the longevity and appearance of your GROHE BAU Ceramic Hand Rinse Basin.
- Daily Cleaning: Wipe the basin with a dry, soft cloth after each use to prevent water spots and soap scum buildup.
- Regular Cleaning: For more thorough cleaning, use a mild, non-abrasive cleaner specifically designed for ceramic surfaces. Apply with a soft sponge or cloth, rinse thoroughly with water, and dry with a soft cloth.
- Avoid Harsh Chemicals: Do not use abrasive powders, scouring pads, strong acids, alkalis, or chemical cleaners containing ammonia or bleach, as these can damage the ceramic finish.
- Drain Maintenance: Periodically clean the drain stopper and overflow channel to remove hair and debris, which can cause blockages.
7. Troubleshooting
This section addresses common issues you might encounter with your basin.
| Problem | Possible Cause | Solution |
|---|---|---|
| Water Leakage | Loose plumbing connections, damaged seals, or improper sealant application. | Check all water supply and drain connections. Tighten any loose fittings. Inspect seals and replace if damaged. Reapply silicone sealant if necessary. |
| Slow Drainage | Clog in the drain or P-trap. | Remove and clean the drain stopper. Disassemble and clean the P-trap. Use a plumbing snake if the clog is further down the pipe. Avoid pouring grease or harsh chemicals down the drain. |
| Basin Not Level | Improper installation or wall mounting. | Loosen mounting bolts slightly, adjust the basin using a level, and retighten evenly. Ensure the wall surface is flat. |
