Use wooden crates, ladders, or even gutters (for kids’ books). Sand and secure them to a wall or stack them creatively.

Seal edges with silicone caulk, use waterproof materials, install a backsplash, and check for leaks regularly.

Use tiered shelves, hanging racks, or a rolling cart to maximize space. Group items by category (glasses, bottles, tools) and add labeled bins for easy access.
