- Preparation: Unpack all components carefully. Lay out the parts and identify them using the parts list in the separate installation manual.
- Determine Orientation: Decide whether the sliding door will open to the left or right. This will dictate the placement of the fixed and sliding panels.
- Mount Wall Profiles: Position the wall profiles vertically on the walls of your niche. Use a spirit level to ensure they are perfectly plumb. Mark drill holes, drill, insert wall plugs, and secure the profiles with screws.
- Install Fixed Glass Panel: Carefully insert the fixed glass panel into its designated wall profile. Ensure it is securely seated.
- Install Top Guide Bar: Attach the top guide bar to the wall profiles, ensuring it is level and provides a stable track for the sliding door. This bar connects the fixed and sliding panels at the top, providing structural integrity and smooth movement.

- Install Handles: Attach the handles to the sliding glass panel.
- Apply Sealing Strips and Silicone: Install all provided sealing strips along the edges of the glass panels and profiles to ensure a watertight enclosure. Apply a high-quality silicone sealant along the exterior joints where the profiles meet the wall and the shower tray/floor. Allow the silicone to cure completely before using the shower.
- Test Operation: Once the silicone is cured, gently test the sliding mechanism to ensure smooth movement and proper closure.
5. Operating Instructions
The Schulte Sliding Niche Shower Door is designed for ease of use. To open or close the door, simply grasp the handle and gently slide the door along its track. Ensure there are no obstructions in the path of the door. The bottom rollers are engineered for smooth and quiet operation. Avoid forcing the door if it encounters resistance.
6. Maintenance and Cleaning
Regular cleaning and proper maintenance will ensure your shower door remains beautiful and functional for years to come. The glass panels are treated with an anti-limescale coating (FIXIL) to reduce water spots and mineral buildup.

6.1. Routine Cleaning
- After each use, wipe down the glass panels with a soft cloth or squeegee to remove excess water and soap residue.
- For general cleaning, use a mild, non-abrasive cleaner specifically designed for glass or bathroom surfaces. Apply with a soft cloth or sponge.
- Avoid using abrasive cleaners, scouring pads, or harsh chemicals (e.g., bleach, ammonia-based cleaners) as these can damage the glass, profiles, and anti-limescale coating.
- Clean the black profiles with a soft cloth and mild soap and water. Do not use abrasive cleaners or solvents.
- Periodically clean the bottom rollers and guide rail to remove any soap scum or debris that may hinder smooth operation.
6.2. Anti-Limescale Coating Care
- The factory-applied anti-limescale coating helps repel water and prevent mineral buildup. To maintain its effectiveness, avoid using harsh chemicals or abrasive tools on the treated surface.
- Only use soft cloths or sponges for cleaning.
- If limescale spots appear over time, use a mild solution of white vinegar and water (1:1 ratio) applied with a soft cloth, then rinse thoroughly.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Door does not slide smoothly. | Debris in the bottom track or on rollers; rollers need lubrication; misaligned track. | Clean the track and rollers thoroughly. Apply a silicone-based lubricant to the rollers. Check for proper alignment of the top bar and bottom guide. |
| Water leakage from the shower enclosure. | Improperly installed sealing strips; insufficient or damaged silicone sealant; gaps in profiles. | Check all sealing strips for proper placement and condition. Reapply silicone sealant where necessary, ensuring a continuous, watertight bead. Inspect profiles for any gaps. |
| Glass appears cloudy or has persistent spots. | Limescale buildup; improper cleaning agents used. | Use a mild vinegar and water solution for limescale. Ensure only recommended cleaning products are used. Wipe glass dry after each use. |
| Door does not close completely. | Obstruction in the track; door misaligned; wall profiles not plumb. | Check for any physical obstructions. Verify the door is properly seated on its rollers and within the track. Re-check the plumb of the wall profiles. |
