Shop for a sturdy plastic shower caddy. Stores stock plenty of dorm-organization products, so you'll have a variety of options.
Buy a pair of flip flops to keep in the caddy. It's better to put on a pair of shower safe shoes than to go barefoot in a communal space.
Choose a high quality bath brush or loofah. Washcloths are fine, but they'll just add to the laundry pile--and few college students want to deal with more laundry.
Stock up on your favorite shampoo, body wash and facial cleanser. Keep extra bottles in your dorm room to cut down on trips to the drug store.
Tote your shower caddy to the bathroom when you need it and bring it back to your dorm room when you're done. This simple step clears clutter from the communal area--and keeps your shower stuff safe.
