This adhesive bathroom shelf set includes 2 clear acrylic units designed for secure, no-drill mounting on smooth, flat surfaces like glass, tile, mirror, metal, fiberglass, and finished wood. Each unit measures 3.8 in. deep by 12.8 in. wide by 3.3 in. high and supports up to 12 lbs. when installed correctly. The shelves feature integrated drain holes in the base to prevent water pooling, making them suitable for humid environments such as showers and sinks. Installation requires cleaning the surface thoroughly, applying the included residue-free adhesive tape, pressing firmly for one minute, and allowing a full 24-hour cure before loading. They are not recommended for rough, porous, or uneven walls including drywall with texture, unfinished brick, or stucco. The transparent design maintains visual openness while supporting daily organization of toiletries, cosmetics, kitchen spices, medications, or craft supplies. Because they require no tools or hardware, these shelves offer flexible repositioning if needed-though repeated removal may reduce adhesive effectiveness. Their slim profile fits tight spaces like narrow shower corners, beside vanities, or above toilets without obstructing function or sightlines.
