Step-by-Step: DIY Tension Rod Under-Sink Organizer
Step 1: Clear & Measure Your Space
Empty out the cabinet and take measurements. Make note of plumbing pipes, trash bins, and any awkward corners. This will help you decide how to position the tension rod and expandable shelf.
Step 2: Install the Tension Rod
Adjust one of the Spring Tension Curtain Rods to fit the width of your cabinet (between 16″–28″). Install it toward the front and higher up so your spray bottles can hang freely without hitting pipes or shelving.
Step 3: Hang Spray Bottles
Fill the spray bottles with your go-to cleaners—like vinegar mix, glass cleaner, or disinfectant—and hang them by their trigger handles over the rod. This frees up shelf and bin space for bulkier items.
Step 4: Add Storage Bins
Use the NUMIFUN clear-lid bins to store items like dishwasher pods, sponges, gloves, and extra trash bags. Stack them neatly or arrange side-by-side for easy access. Label each bin using the Avery removable labels for instant visibility.
Step 5: Add a Cabinet Shelf Riser
Install the Expandable Cabinet Shelf Organizer under your sink (choose a narrow size for tight spaces). Place shorter bottles underneath and smaller bins or towels above to double your vertical space.
Step 6: Use Command Hook for Extras
Attach the Command Caddy Hanger to the inside of the cabinet door or side panel. Use it to hang a small basket, caddy, or cleaning cloth bag for bonus storage—without drilling.
Pro Tips for Maximum Efficiency
- Use the second tension rod horizontally along the base of the cabinet to prevent bins from sliding forward.
- Label everything: even if bins are see-through, labels save time and reduce mess.
- Wipe down bottles before organizing to keep your new system clean and fresh.
- Dedicate one bin to backup items like refills or seasonal products to reduce clutter.
Best Items to Store Under the Sink
- Cleaning sprays and solutions
- Sponges, cloths, and scrubbers
- Garbage bags and liners
- Extra dish soap and gloves
- Small first-aid or repair kits
- Pet or BBQ cleaning tools
- Air fresheners or moisture absorbers
