This 4-tier slim bathroom storage cabinet on casters brings flexible movable storage to bathrooms that benefit from rolling-cabinet versatility rather than fixed placement. The rolling casters let the cabinet move from toilet-side storage during the morning routine to a tucked-away corner spot during showers or guest visits, distinct from the fixed-position cabinets that commit to one wall position for the long term.Construction uses Mdf panels with a moisture-resistant finish that handles bathroom humidity without warping, finished in a warm brown tone that complements wood-accent bathroom themes. At 16 inches wide by just 7 inches deep, the cabinet fits the narrow channel beside a toilet, between vanity and wall, or against the slim corner of a half bath without crowding the walking path.The cabinet combines a pull-out top drawer (11 by 5 by 3 inches) with a middle compartment (14 by 4.5 by 4.5 inches) for medium-height items and a bottom compartment (14 by 4.5 by 13 inches) for taller bottles or stacked towels. Total weight capacity reaches 66 pounds across all tiers, plenty for a typical bathroom inventory of supplies. The 23-pound assembled body rolls smoothly on the casters without flexing under loaded contents. Whether the bathroom is a primary suite needing organized supplies, a guest bath that wants flexible storage, or a half bath where wall storage simply does not fit, this rolling cabinet earns its 16-inch footprint.
