Setup and Installation
This section outlines the general steps for installing your wall-mount lavatory. Specific details may vary based on your plumbing configuration and local building codes. Always consult local plumbing codes before installation.
1. Pre-Installation Checks

- Verify that water supply lines and drain rough-ins are correctly positioned according to the lavatory's dimensions.
- Gather all necessary tools, including a level, tape measure, drill, wrenches, and sealant.
2. Mounting the Lavatory
- Mark the desired height and mounting points on the wall using the lavatory's template or measurements. Ensure the marks are level.
- Drill pilot holes at the marked locations.
- Secure the mounting brackets or bolts into the wall studs or appropriate anchors.

3. Connecting Plumbing
- Install the faucet and drain assembly onto the lavatory according to their respective manufacturer's instructions.
- Connect the hot and cold water supply lines to the faucet inlets. Hand-tighten, then use a wrench for a final quarter-turn.
- Connect the drain tailpiece to the P-trap and then to the wall drain. Ensure all slip nuts are tightened securely.
- Apply a bead of silicone sealant around the perimeter of the lavatory where it meets the wall, if desired, for a finished look and moisture seal.
- Turn on the main water supply slowly and check for leaks at all connections. Tighten any leaking connections as needed.
Operating
The KOHLER Brenham Wall Mount Lavatory operates like any standard sink. Turn the faucet handles to control water flow and temperature. Ensure the drain stopper is properly seated to retain water in the basin when desired. After use, ensure the water is turned off completely to prevent waste and potential overflow.
Maintenance
Proper care and maintenance will help preserve the finish and functionality of your lavatory.
Cleaning Instructions
- Clean the vitreous china surface regularly with a soft, dry cloth.
- For deeper cleaning, use a mild, non-abrasive cleaner specifically designed for bathroom fixtures.
- Avoid harsh chemicals, abrasive scrubbers, or acidic cleaners, as these can damage the finish and void the warranty.
- Rinse the lavatory thoroughly with clean water after cleaning and wipe dry to prevent water spots.
