Installation Guide
Faucet Installation
Pre-Installation
- Turn off the main water supply.
- Clear the area under the sink for easy access.
- Ensure your sink has a compatible hole configuration (1 or 3 holes).
Step-by-Step Faucet Installation
- Prepare the Sink Hole: For a single-hole installation, ensure the hole size is between 0.99-1.6 inches. For a 3-hole installation, use the included deck plate (6.3 inches wide) to cover the outer holes.
- Mount the Faucet: Place the faucet body through the sink hole. Secure it from underneath the sink using the provided mounting hardware (gasket, washer, and nut).
- Connect Water Lines: Attach the hot and cold water supply lines to the corresponding inlets on the faucet. The standard connector size is 1/2-inch. Ensure connections are tight to prevent leaks.
- Test for Leaks: Once all connections are secure, slowly turn on the main water supply and check for any leaks around the faucet and supply lines.

Shower System Operation
The shower system includes a 3-function control valve to switch between the rain shower head, handheld shower, or a combination.
- Function Selection: Use the control valve handle to select the desired water outlet. The valve typically allows for switching between the rain shower, handheld shower, or both simultaneously.
- Water Flow and Temperature: Adjust the main handle on the control valve to regulate water flow and temperature.
- Rain Shower Head: The 12-inch rain shower head injects air into the water for a natural rainfall experience. The angle can be adjusted for optimal coverage.
- Handheld Shower: The high-pressure handheld shower is designed to provide strong water flow, useful for targeted rinsing.
Maintenance
Proper maintenance will ensure the longevity and optimal performance of your BATHLAVISH products.
Cleaning the Faucet
- Clean the matte black finish with a soft, damp cloth.
- Use mild soap and water if necessary.
- Avoid abrasive cleaners, harsh chemicals, or scouring pads, as these can damage the finish.
- Wipe dry after cleaning to prevent water spots.
Cleaning the Shower Head
- The rain shower head features silica gel outlets designed for easy cleaning.
- If water flow becomes restricted due to mineral buildup, gently rub the silica gel nozzles with your finger or a soft brush to dislodge deposits.
- For more stubborn buildup, a solution of white vinegar and water can be used. Soak the shower head (if removable) or apply the solution with a cloth, then rinse thoroughly.
