18+ Under-Sink Storage Hacks for Every Room
The space under the sink is often messy, forgotten, or packed with random items — but with a few smart hacks, it can become one of the most organized spots in your home.
Whether it’s the kitchen, bathroom, laundry room, or even a utility sink, these under-sink storage ideas help you maximize every inch while keeping things tidy and easy to reach.
1. Add a Two-Tier Sliding Organizer
A double-layer slide-out system makes it easy to access cleaning products, toiletries, or tools without digging through clutter.
Pro Tip: Choose a model with removable baskets for quick cleaning.
2. Use Stackable Bins With Handles
Stackable bins help separate categories like cleaning supplies, sponges, or grooming items while keeping everything portable.
Pro Tip: Pick bins with built-in handles so you can pull them out like drawers.
3. Install a Tension Rod for Hanging Sprays
Spray bottles take up a lot of vertical space — a tension rod lets you hang them neatly while freeing up room below.
Pro Tip: Pair this hack with small bins underneath for cloths and brushes.
4. Use a Lazy Susan for Easy Access
A small turntable lets you spin around bottles, oils, soaps, or wipes without reaching into the back.
Pro Tip: Choose a non-slip turntable to prevent sliding.
5. Add Adhesive Hooks to the Cabinet Walls
Hooks inside the doors or along the cabinet walls offer extra spots for gloves, brushes, or towels.
Pro Tip: Use waterproof adhesive hooks for bathroom or laundry rooms.
6. Install a Narrow Under-Sink Shelf
A slim shelf fits around the plumbing and gives you two usable layers for storage.
Pro Tip: Adjustable shelves work best because pipes vary from home to home.
7. Use Clear Acrylic Drawers
Clear drawers let you store beauty products, dish items, or detergents while still seeing everything at a glance.
Pro Tip: Stack two or three drawers for maximum efficiency.
8. Add a Door-Mounted Organizer
The inner side of the cabinet door is ideal for holding small bottles, soap refills, brushes, or trash bags.
Pro Tip: Choose low-profile racks so the door closes smoothly.
9. Corral Items With Mini Baskets
Small baskets keep loose items from spreading out and getting lost in the back of the cabinet.
Pro Tip: Use one basket per category so the space stays organized long-term.
10. Create a Cleaning Caddy
A portable caddy under the sink keeps your everyday cleaning supplies organized and ready to grab.
Pro Tip: Restock the caddy weekly to keep it useful.
11. Store Trash Bags on a Rod or Dispenser
Mount a small rod or roll-out dispenser to keep trash bags tidy and easy to pull.
Pro Tip: Install it high enough so it doesn’t block other storage.
12. Use a File Organizer for Cutting Boards
In the kitchen, file organizers are perfect for keeping cutting boards, trays, and baking sheets upright.
Pro Tip: Choose a coated metal version to resist moisture.
13. Add a Small Drawer Unit for Bathroom Items
A compact drawer system keeps razors, skincare, hair tools, and extras neatly separated.
Pro Tip: Use drawer labels if multiple people share the bathroom.
14. Use Vertical Risers for Extra Levels
Risers create more shelving for taller bottles or baskets while keeping everything easy to access.
Pro Tip: Metal risers offer the most stability under heavy items.
15. Install LED Motion Lights
Small motion lights help you see everything clearly without opening the doors wide or turning on overhead lights.
Pro Tip: Choose rechargeable LED strips to avoid wiring.
16. Use a Baking Rack for Towel Storage
A simple wire baking rack can store rolled-up washcloths or hand towels in small bathrooms.
Pro Tip: Roll towels tightly so they don’t topple over.
17. Add a Slide-Out Trash + Recycling Combo
A dual slide-out bin fits neatly under the kitchen sink and keeps waste organized and hidden.
Pro Tip: Choose soft-close rails for a smoother experience.
18. Keep a Small Toolbox or Repair Kit Under Utility Sinks
For laundry rooms or garage sinks, a compact toolkit keeps essentials like pliers, nails, and screwdrivers within easy reach.
Pro Tip: Store tools in a lidded box to protect them from moisture.
19. Use Waterproof Mats to Protect the Cabinet Base
A mat protects the cabinet floor from leaks, spills, or cleaning bottle drips.
Pro Tip: Choose one with raised edges for extra protection.
