Install floating shelves, over-the-toilet cabinets, or woven baskets. Repurpose old crates or mason jars for toiletries and add peel-and-stick hooks for robes/towels.

Install a wall-mounted copper pipe rack near a heating vent, or use a heated towel rail kit with simple electrical wiring.

Use moisture-resistant wood or PVC boards, sturdy brackets, and wall anchors. Measure and level the shelves before securing them to studs or tile with appropriate drill bits and screws. Seal wood shelves with waterproof paint or varnish.
