This shower caddy uses a suction cup system designed for smooth, non-porous surfaces such as ceramic tile (uncracked), glass, mirrors, polished metal, stainless steel, and acrylic. It should not be placed over painted drywall, wood, wallpaper, or other rough or cracked walls. For initial placement issues, clean the suction cup, dry it with a hair dryer, and test on a smooth surface; if the suction holds, the wall might be suitable elsewhere, so relocate as needed. Installation requires no drilling, screws, holes, glue, or tools. On a dry, smooth surface without grout, remove the protective cover and press the board firmly until you hear a set, typically in a second. The unit uses a TPE suction cup with a flexible octopus-tentacle grip and an ABS plastic hook to handle temperature changes and moisture over time. It can hold up to about 22 lbs. and has a compact basket measuring around 10.8 by 3.7 by 2.9 in. Drainage is built-in with multiple holes and a slight downward angle to promote airflow and faster drying. The basket is removable for versatile use beyond the shower, and additional hooks accommodate towels or brushes while keeping products organized. This setup minimizes clutter and makes everyday bathroom routines a touch easier. Color: White.
