Installation
The Mepplzian Arched Medicine Cabinet offers both recessed (in-wall) and wall-mounted installation options. The cabinet is 95% pre-assembled, requiring minimal setup.
1. Pre-Installation Measurements
Before installation, carefully measure your space to ensure proper fit and clearance. Consider the location of existing light fixtures and faucets.
- For Height (H): If you have a bathroom pendant light, measure the distance from the bottom of the light to the faucet. The suitable height range for the mirror cabinet is H minus 2 to 6 inches.
- For Width (W): If you have bathroom wall lights, measure the distance between the two wall lights. The suitable width range for the mirror cabinet is W minus 2 to 6 inches.
- Ensure a distance of 1 to 3 inches between the cabinet and any light fixture, or between the cabinet and the faucet.

Maintenance
- Cleaning the Mirror: Use a soft, lint-free cloth and a non-abrasive glass cleaner. Spray the cleaner onto the cloth, not directly onto the mirror, to avoid liquid seeping into the edges.
- Cleaning the Cabinet: Wipe the metal frame and interior surfaces with a soft, damp cloth. For stubborn marks, a mild soap solution can be used, followed by drying thoroughly. Avoid harsh chemicals or abrasive cleaners.
- Inspecting Hinges: Periodically check the door hinges for any signs of loosening. Tighten screws if necessary to ensure smooth operation and prevent misalignment.
- Avoid Excessive Moisture: While the cabinet is waterproof, prolonged exposure to excessive moisture should be avoided to maintain its finish and structural integrity.
Troubleshooting
This section addresses common issues you might encounter with your medicine cabinet.
Door Does Not Close Securely:
- Check if the magnetic buckle is aligned properly with the metal plate on the cabinet frame.
- Ensure there are no obstructions preventing the door from closing fully.
- Inspect hinges for damage or looseness. Tighten any loose screws.
Mirror Appears Wobbly After Installation:
- Verify that all mounting hardware is securely fastened to both the wall and the cabinet.
- Ensure the wall surface is flat and stable. If the wall is uneven, this could affect stability.
Scratches or Damage During Installation:
