Buying Guide: Key Considerations for Small RV Medicine Cabinets
What mounting style works best in your RV? Recessed units maximize wall space but require precise cavity preparation. Wall-mounted cabinets are easier to install and swap if you move, but they may protrude more into the living area. Over-the-toilet designs can save floor space in compact bathrooms but require adequate clearance above the toilet.
How much storage do you need? Consider the number of daily meds, first-aid items, and skincare products you carry. Look for adjustable shelves to fit varying item heights and widths. If you travel with larger bottles, prioritize deeper shelves or taller interior space.
What materials and moisture resistance matter? RV bathrooms experience humidity waves, so choose cabinets with moisture-resistant finishes or materials like MDF with sealed edges or durable plastics. Plastic composites are easy to wipe clean but may lack the premium look of wood alternatives.
Are there safety features you want? Doors with soft-close hinges or mirrored doors can add convenience. A towel bar or hooks can convert unused space into practical storage. If children travel with you, consider locking mechanisms or doors that stay securely closed while moving.
Installation considerations: confirm wall thickness, mounting hardware compatibility, and weight capacity. For over-toilet models, ensure the area above the toilet is unobstructed and the weight is evenly distributed across the mounting surface.
