4. Setup and Installation
This bathtub spout is designed for wall-mounted, single-hole installation. Follow these steps carefully:
- Preparation: Turn off the main water supply to the bathroom. Clear the installation area and ensure the wall surface is clean and ready for mounting.
- Mounting Location: Determine the precise wall-mounting position for the spout. Mark the drilling points for the mounting plate.
- Secure Mounting Plate: Drill holes at the marked points and insert appropriate wall anchors. Attach the mounting plate securely to the wall using the provided screws. Ensure the plate is level.
- Connect Water Lines: Connect the hot and cold water supply lines to the corresponding inlets on the spout assembly. Use plumber's tape or thread sealant on all threaded connections to ensure a watertight seal.
- Install Spout: Carefully slide the bathtub spout onto the secured mounting plate, ensuring all connections are properly aligned and seated. Secure the spout to the mounting plate according to the specific hardware design.

6. Maintenance and Care
To maintain the pristine Supersteel finish and ensure the longevity of your GROHE Lineare Bathtub Spout, follow these care instructions:
- Regular Cleaning: Clean the spout regularly with a soft cloth and a mild, non-abrasive soap or a cleaner specifically designed for bathroom fixtures.
