4. Installation Guide
The APPASO Shower Niche is designed for simple installation. Follow these steps carefully to ensure proper fitting and functionality.
4.1. Pre-Installation Considerations
- Ensure the wall area is clear of electrical wiring, plumbing, and structural elements before cutting.
- Verify the wall thickness can accommodate the niche's depth (3.9 inches / 10 cm).
- The ideal installation height for the niche is typically between 1000-1500mm (approximately 39-59 inches) from the floor, but adjust according to user preference.
4.2. Required Wall Opening Size
Before cutting, accurately measure and mark the wall opening. The recommended wall opening size is crucial for a proper fit.
- Width: 11.8 inches (30.1 cm)
- Height: 23.6 inches (60.3 cm)

4.3. Step-by-Step Installation
- Prepare the Wall: Based on the required dimensions, carefully cut an opening in the wall using appropriate tools. Ensure the edges are clean and precise.
- Insert the Niche: Gently slide the APPASO Shower Niche into the prepared wall opening. Ensure it fits snugly and is flush with the wall surface.
- Secure the Niche: Apply a suitable waterproof sealant or adhesive around the perimeter of the niche where it meets the wall to create a watertight seal. Use the provided tapes to temporarily hold it in place if necessary.
- Tile Integration (Optional): If tiling around the niche, ensure the tiles are cut to fit precisely around the niche's frame for a seamless finish. The niche is designed to integrate without requiring additional tiling on its internal surfaces.
- Curing Time: Allow the sealant to cure completely according to the manufacturer's instructions before exposing the niche to water.

Proper care will ensure the longevity and appearance of your APPASO Shower Niche.

7. Troubleshooting
This section addresses common issues you might encounter with your shower niche.
| Problem | Possible Cause | Solution |
|---|---|---|
| Water pooling in the niche. | Improper installation angle or debris obstructing the drip slope. | Ensure the niche is installed with the correct 92-degree incline. Clean any debris from the bottom surface. If the issue persists, re-evaluate installation. |
| Niche appears loose in the wall. | Insufficient sealant or improper wall opening size. | Reapply sealant around the edges. If the opening is too large, additional shims or structural support may be required before resealing. |
