Installing a Kohler Anessia touchless faucet can transform the functionality and aesthetic of your kitchen or bathroom, offering a blend of sleek design and advanced hygiene technology. This comprehensive guide walks you through the entire process, ensuring a smooth and successful Kohler Anessia touchless faucet installation. From gathering the right tools to testing the final water flow, we cover every detail to empower you to complete this project with confidence.
Preparing for Your Kohler Anessia Touchless Faucet Installation
Before turning a single valve, proper preparation is the cornerstone of a successful Kohler Anessia touchless faucet installation. This specific model requires a stable power source, typically two AA batteries, to operate its sensor and smart control features. You will also need a basin wrench, a pair of adjustable wrenches, plumber’s tape, a bucket, and rags to manage any residual water. Carefully reviewing the installation instructions included in the Anessia box is crucial, as it provides model-specific guidance and safety warnings that generic advice cannot match.
Shutting Off Water and Clearing the Space
Locate the water supply valves under your sink and turn them clockwise to shut off the hot and cold water lines. Open the faucet at the sink to drain any remaining water from the lines into the bucket. Disconnect the water supply lines from the faucet using your adjustable wrenches, placing the bucket underneath to catch any drips. This step is non-negotiable for a dry and safe workspace, allowing you to focus entirely on the Kohler Anessia touchless faucet installation without the threat of unexpected water spray.

Removing the Old Faucet and Prepping the Area
With the water disconnected, use the basin wrench to remove the mounting nuts securing the old faucet to the sink or countertop. Gently lift the old fixture away, being mindful of the spray head and handle connections. Now is the perfect time to inspect the sink hole; the Kohler Anessia requires a single-hole installation. If your current setup has three holes, you will need to either use the existing center hole or purchase a mounting plate to cover the extra holes for a clean, professional look.
Connecting the Water Lines
Take the new Kohler Anessia faucet and attach the flexible water supply lines that were included in the package. Wrap plumber’s tape clockwise around the threads of the faucet's inlet connections to prevent future leaks. Securely connect the hot and cold lines to the corresponding valves, tightening them firmly with your wrenches. Double-check that these connections are tight, as leaks at this stage can cause significant damage once the water is turned back on.
The Final Steps of the Kohler Anessia Touchless Faucet Installation
Lift the faucet body straight up and place it into the single sink hole. Adjust the position so the faucet aligns perfectly with the front of the sink. From underneath the sink, thread the mounting nut onto the base of the faucet and hand-tighten it securely. Avoid overtightening, as this can crack a porcelain sink or damage the fixture’s finish. Once mounted, reconnect the water supply lines to the faucet and ensure the spray head hose is properly threaded through any necessary openings.

Powering On and Sensor Calibration
Insert the two AA batteries into the battery compartment located under the faucet spout, following the positive and negative indicators. With the power source active, slowly turn the water supply valves back counterclockwise. Observe the base of the faucet for any signs of leaks immediately as the pressure builds. The Kohler Anessia touchless faucet is now live; wave your hand in front of the sensor to activate the spray and verify that the water flows correctly. The smart controller allows for touch-free operation, marking the successful completion of your installation.
Troubleshooting and Performance Tips
Even after a seemingly flawless Kohler Anessia touchless faucet installation, you might encounter minor issues that are easily resolved. If the faucet fails to activate, check the battery polarity and ensure the batteries are fresh. If the water flow is inconsistent, air in the lines is often the culprit—turn the water back on with the faucet activated to purge any trapped air. For optimal performance, avoid placing metal objects directly under the sensor, and periodically wipe the sensor window clean to maintain its infrared sensitivity.
| Step | Action | Critical Tip |
|---|---|---|
| 1 | Shut off water supply valves | Verify water is fully drained before disconnecting old faucet |
| 2 | Disconnect old faucet and remove hardware | Use a basin wrench for tight access under the sink |
| 3 | Connect new water supply lines to faucet | Use fresh plumber’s tape to ensure a leak-proof seal |
| 4 | Mount faucet and secure with mounting nut | Hand-tighten first; only use tools for final quarter turn |
| 5 | Insert batteries and turn water back on | Check for leaks at the base and supply connections immediately |
Successfully completing a Kohler Anessia touchless faucet installation brings immediate rewards in terms of convenience and hygiene. The smooth, arc-free spray provides efficient rinsing, while the touchless operation drastically reduces the spread of germs in high-traffic areas. By following these detailed steps, you have not only saved on installation costs but also gained valuable plumbing knowledge that ensures your new fixture will function reliably for years to come.
