4.2 General Installation Steps
- Preparation: Ensure the shower area is prepared, including any necessary plumbing and tiling. If using a shower tray, ensure it is correctly installed and leveled.
- Marking: Position the wall profiles against the wall in the desired location and mark the drilling points. Use a spirit level to ensure vertical alignment.
- Drilling: Drill holes at the marked points and insert appropriate wall plugs.
- Mounting Profiles: Secure the aluminum wall profiles to the wall using the provided screws. Adjust as necessary to compensate for wall irregularities.
- Glass Panel Installation: Carefully insert the fixed glass panels into the wall profiles. Ensure they are properly seated and secured according to the detailed assembly instructions.
- Door Installation: Attach the double-swing doors to the fixed panels or wall profiles as per the instructions. Install the magnetic closure mechanism.
- Sealing: Apply silicone sealant to all external joints between the profiles and the wall, and along the bottom edge of the enclosure to prevent water leakage. Allow sufficient drying time.

6. Maintenance and Cleaning
Regular cleaning and maintenance will ensure the longevity and appearance of your shower enclosure.
6.1 Nano-Coating Benefits
The 8 mm tempered safety glass is treated with a nano-coating, creating a 'lotus effect'. This surface sealing protects the glass from new dirt and limescale buildup, allowing water to simply roll off. The coating is transparent, non-corrosive, and easy to clean.

6.2 Cleaning Instructions
- Glass Panels: For daily cleaning, simply wipe the glass with a soft cloth or squeegee after each use to remove water droplets. For deeper cleaning, use a mild, non-abrasive glass cleaner. Avoid harsh chemicals or abrasive sponges, as these can damage the nano-coating.
- Profiles and Hardware: Clean aluminum profiles and chromed hardware with a soft cloth and mild soap and water. Rinse thoroughly and dry to prevent water spots.
- Seals: Regularly check and clean the rubber seals to prevent mold and mildew buildup.
7. Troubleshooting
If you encounter any issues with your shower enclosure, refer to the following common problems and solutions:
- Water Leakage:
- Check all silicone seals for cracks or gaps. Reapply sealant if necessary.
- Ensure the bottom seals on the doors are intact and making proper contact with the shower tray or floor.
- Verify that the wall profiles are securely fastened and sealed against the wall.
- Doors Not Closing Properly:
- Inspect the magnetic strips for damage or misalignment.
- Check if the doors are properly aligned and swinging freely. Adjust hinges if possible according to the assembly instructions.
- Squeaking Hinges:
- Apply a small amount of silicone-based lubricant to the hinges. Avoid oil-based lubricants.
