2. Setup and Installation
This hand shower is designed for easy installation. Ensure your water supply is turned off before beginning installation.
2.1. Connecting to Your Shower Hose
The GROHE SmartActive hand shower is compatible with most standard shower hoses. If connecting to a non-GROHE hose, an adapter may be required to ensure a secure, leak-free connection. Please refer to the following guidelines:
- For LIXIL (INAX), TOTO, KAKUDAI, or SANEI hoses (excluding balance type): Use adapter JPK03200. An adapter is necessary if water leaks from the joint between the shower head and hose. If no leakage occurs, an adapter is not required.
- For MYM hoses: Use adapter JPK03300.
- For KVK hoses: Use adapter JPK03400.
Screw the hand shower onto your existing shower hose. Hand-tighten first, then use a wrench if necessary, being careful not to overtighten. Check for leaks after turning on the water supply.

4. Maintenance
To ensure the longevity and optimal performance of your GROHE SmartActive hand shower, regular cleaning is recommended. Wipe the chrome surface with a soft cloth and a mild cleaning agent. Avoid abrasive cleaners or scouring pads, as these can damage the finish. For limescale buildup on the spray nozzles, gently rub them with your finger or a soft brush to dislodge deposits.
5. Troubleshooting
If you encounter any issues with your hand shower, please refer to the following common troubleshooting tips:
- Reduced Water Flow: Check for limescale buildup in the nozzles. Clean as described in the Maintenance section. Ensure the water supply valve is fully open.
- Water Leakage at Connection: Ensure the shower head is securely tightened to the hose. If using an adapter, verify it is the correct type and properly installed. Check the rubber washer (gasket) inside the connection for damage or improper seating.
- Difficulty Switching Spray Patterns: Ensure the selector button is clean and free of debris. If the issue persists, contact customer support.
