2. Setup and Installation
This tub filler requires a separate rough-in set (GROHE model 29 038 001) for installation. This rough-in set is sold separately and is essential for the proper mounting and plumbing connections of the floor standing tub filler.
Professional installation is highly recommended to ensure proper function, adherence to local plumbing codes, and to maintain the product warranty. Ensure the floor is adequately reinforced to support the weight of the tub filler and water when filled.
Installation Steps (General Guidance):
- Prepare the Installation Area: Ensure the floor is level and structurally sound. Mark the precise location for the rough-in set according to the rough-in set's instructions.
- Install the Rough-In Set: Follow the detailed instructions provided with the GROHE 29 038 001 rough-in set to secure it to the floor and connect the hot and cold water supply lines.
- Mount the Tub Filler: Once the rough-in set is installed and tested, carefully attach the GROHE Plus Floor Standing Tub Filler to the rough-in set, ensuring all connections are secure and watertight.
- Connect Hand Shower: Attach the hand shower hose to the designated outlet on the tub filler and secure the hand shower in its holder.
- Test for Leaks: Slowly turn on the water supply and check all connections for any signs of leakage. Operate the faucet and hand shower to ensure proper function.

3. Operating Instructions
3.1 Water Flow and Temperature Control
The single lever handle on the tub filler controls both the water flow and temperature. The GROHE SilkMove ceramic cartridge ensures smooth and effortless operation.
- To turn on/off water: Lift the handle upwards to start water flow. Push the handle downwards to stop water flow.
- To adjust water flow: The further you lift the handle, the greater the water flow.
- To adjust temperature: Move the handle to the left for hotter water and to the right for colder water.
3.2 Diverter Function (Bath Spout / Hand Shower)
The tub filler features an automatic diverter, allowing you to switch between the main bath spout and the hand shower with ease.
- To fill the tub: Ensure the hand shower is securely docked in its holder. Water will automatically flow from the main bath spout.
- To use the hand shower: Simply lift the hand shower from its holder. The water flow will automatically divert from the main spout to the hand shower.
- To return to bath spout: Place the hand shower back into its holder. The water flow will automatically revert to the main bath spout.

4. Maintenance and Care
Proper care and maintenance will ensure the longevity and pristine appearance of your GROHE Plus Floor Standing Tub Filler.
4.1 Cleaning the Finish
The GROHE StarLight chrome finish is highly durable and designed for easy cleaning. To maintain its luster:
- Clean regularly with a soft cloth and mild soap or a non-abrasive cleaner specifically designed for chrome finishes.
- Always rinse thoroughly with clean water after cleaning to remove any cleaner residue.
- Dry the surface with a soft, clean cloth to prevent water spots and maintain shine.
- Avoid: Abrasive sponges, scouring agents, or cleaners containing alcohol, acids, or ammonia, as these can damage the finish and void the warranty.
4.2 SpeedClean Nozzles
The hand shower is equipped with GROHE SpeedClean nozzles, which are designed for easy removal of limescale deposits.
- To clear any mineral buildup, simply wipe the rubber nozzles on the hand shower with your finger. This flexible material allows for quick and effective cleaning.
5. Troubleshooting
If you encounter any issues with your GROHE Plus Floor Standing Tub Filler, refer to the following common troubleshooting steps. For complex problems, contact a qualified plumber or GROHE customer service.
| Problem | Possible Cause | Solution |
|---|---|---|
| Low Water Flow | Partially closed supply valves, clogged aerator, rough-in set restriction. | Ensure hot and cold water supply valves are fully open. Unscrew and clean the aerator at the end of the spout. Verify rough-in set installation. |
| Inconsistent Water Temperature | Incorrect hot/cold supply connections, temperature limiter setting. | Check plumbing connections for correct hot and cold lines. If applicable, adjust the temperature limiter on the ceramic cartridge (consult rough-in set manual or professional). |
| Leaks from Faucet Base or Connections | Loose connections, damaged seals. | Gently tighten accessible connections. Do not overtighten. If leaks persist, turn off water supply and contact a qualified plumber. |
| Diverter Not Switching Properly | Hand shower not fully docked, internal diverter issue. | Ensure the hand shower is fully seated in its holder. If the issue continues, internal inspection by a professional may be required. |
