Installation Instructions
Surface Preparation
Ensure the mounting surface is smooth, clean, and dry. The adhesive works on various surfaces such as tiles, drywall, concrete, glass, marble, and metal. Do not use on porous surfaces or wallpaper.
Warning: Surface damage may occur if adhesive mounting is removed from drywall, concrete, wallpaper, and porous surfaces.
Mounting the Shelf
- Clean the desired corner surface thoroughly with a non-abrasive cleaner and dry completely.
- Peel the protective backing from the adhesive strips located on the back of the shelf.
- Align the shelf with the corner, ensuring it is level.
- Press firmly against the wall for at least 30 seconds to ensure strong adhesion.
- Allow the adhesive to cure for 24 hours before placing items on the shelf to ensure maximum bond strength.

Maintenance and Care
To maintain the appearance and functionality of your shower shelf:
- Regularly clean the shelf with mild soap and water.
- Wipe dry with a soft cloth to prevent water spots and soap scum buildup.
- The integrated drainage system helps keep the shelf clean and dry, but occasional cleaning is recommended.
Troubleshooting
Shelf Detachment
If the shelf detaches from the wall, it may be due to improper installation, exceeding the weight limit, or surface incompatibility. The maximum recommended load is 5 pounds (2.7 kg).
- Ensure the surface was thoroughly cleaned and dry before application.
- Verify the surface is smooth and non-porous.
- Do not overload the shelf.
- If re-installation is necessary, new adhesive strips may be required. Contact Umbra customer support for replacement adhesive strips.
Adhesive Residue Removal
If adhesive residue remains on the wall after removal, it can be challenging to remove, especially from certain surfaces. Use appropriate adhesive removers (e.g., Goo Gone) and follow product instructions carefully. Test on an inconspicuous area first.
