5. Setup and Installation
The COSTWAY medicine cabinet offers two installation methods: recess mount or surface mount. Choose the method that best suits your bathroom layout and wall structure. All necessary wall-mounting hardware is included.
5.1 Pre-Installation Checklist
- Ensure you have the correct tools: drill, level, measuring tape, screwdriver, stud finder (recommended).
- Identify the desired location for the cabinet, considering height, accessibility, and clearance for door opening.
- For recess mount, verify wall cavity dimensions match the cabinet's recessed portion.
- For surface mount, ensure the wall can support the cabinet's weight when fully loaded.
5.2 General Installation Steps
- Unpack and Inspect: Carefully remove all components from the packaging. Inspect for any damage or missing parts.
- Assemble Cabinet Body: Follow the detailed assembly instructions provided in the separate assembly guide (if applicable) to construct the main cabinet frame.
- Mark Mounting Points: Hold the cabinet against the wall at the desired height and use a level to ensure it is straight. Mark the locations for drilling mounting holes.
- Drill Holes and Install Anchors: Drill pilot holes at the marked locations. Insert appropriate wall anchors (provided) if drilling into drywall. If mounting into studs, drill pilot holes suitable for the mounting screws.
- Secure Cabinet: Carefully lift the cabinet and align the mounting holes with the drilled holes/anchors. Secure the cabinet to the wall using the provided screws. Ensure it is firmly attached and stable.
- Install Doors and Shelves: Attach the mirrored doors using the soft-close hinges. Adjust hinges as needed for proper door alignment. Insert the shelves into the desired positions within the cabinet.


6. Operating Instructions
Your COSTWAY medicine cabinet is designed for convenient storage and daily grooming.
6.1 Using the Mirrored Doors
- The three frameless mirrored doors provide a clear reflection for daily grooming tasks.
- Open and close the doors gently. The soft-close hinges are designed for quiet operation and extended product life.

6.2 Organizing Storage Space
- Utilize the six internal compartments to store toiletries, cosmetics, skincare products, and other bathroom essentials.
- Arrange items to distribute weight evenly across the shelves.

7. Maintenance
Proper care will ensure the longevity and appearance of your medicine cabinet.
- Cleaning the Surface: The cabinet features a waterproof surface. Wipe down the exterior and interior with a soft, damp cloth and a mild, non-abrasive cleaner. Dry immediately with a clean cloth.
- Cleaning Mirrors: Use a standard glass cleaner and a lint-free cloth to clean the mirrored surfaces. Avoid spraying cleaner directly onto the mirror edges to prevent moisture damage.
- Hinge Care: The soft-close hinges are designed for durability. If doors become misaligned over time, adjust the screws on the hinges as needed. Avoid applying excessive force when opening or closing doors.
- Avoid Harsh Chemicals: Do not use abrasive cleaners, ammonia-based products, or solvents, as these can damage the finish and mirror coating.
8. Troubleshooting
If you encounter any issues with your medicine cabinet, refer to the following common solutions:
- Doors not closing properly: Check for obstructions. Adjust the soft-close hinges using a screwdriver to ensure proper alignment.
- Cabinet feels unstable: Re-check all mounting screws to ensure they are tight and the cabinet is securely fastened to the wall. If using wall anchors, ensure they are correctly installed and suitable for your wall type.
- Mirror appears cloudy or streaky: Clean with a dedicated glass cleaner and a clean, lint-free microfiber cloth. Ensure no residue is left behind.
