Spiff up your kitchen with an easy under-sink organization plan and a simple DIY under-sink mat.
Kitchen organization can feel overwhelming, especially when it comes to the space under the sink. That awkward, deep cabinet collects cleaning supplies, garbage bags, and odds and ends, and it’s easy to ignore.
Alongside figuring out how to organize kitchen cabinets, I’d long been avoiding the under-sink area. I put off cleaning it for months—maybe years. But when I finally tackled it, the process was straightforward, quick, and surprisingly satisfying.
Simple Under Kitchen Sink Organization Ideas + a DIY Cabinet Mat
Note: This post mentions product ideas for convenience.
1. Start by emptying everything out
To truly organize the space, take everything out. Empty the cabinet completely so you can see what you have, identify what’s expired or unused, and clean every surface.
2. Soak containers and clean garbage bins
While you scrub the cabinet interior, set smaller plastic containers and lids to soak in hot, soapy water. If your garbage or recycling bins need freshening, fill them with warm soapy water and let them sit for a bit before rinsing and drying.
3. Thoroughly wash and dry the cabinet
You don’t need harsh chemicals to get a clean under-sink cabinet. A spray bottle of warm water with a few drops of dish soap and a soft cloth works well. Wipe down walls, corners, and the cabinet floor, then dry everything thoroughly to prevent mildew and lingering odors.
Even with a good cleaning, cabinet floors often show stains or worn finishes. A protective mat helps hide cosmetic damage, makes the cabinet look fresh, and makes future cleanups easier.
4. Make a simple DIY under-sink cabinet mat
Supplies you’ll need:
- A large cardboard box, unfolded flat
- Tape measure
- X-acto knife or utility knife
- Scissors
- Long straight edge (level or ruler)
- Marble-look contact paper or other waterproof adhesive covering
- Flatten the cardboard and measure the interior base of your cabinet.
- Trim the cardboard to fit that footprint, leaving a little extra for trimming if needed.
- Cut two pieces of contact paper slightly wider than the cardboard so you can wrap the edges underneath.
- Peel the backing and adhere the contact paper to the cardboard, smoothing out bubbles and wrapping the edges underneath. Overlap pieces as necessary for full coverage.
A DIY mat like this immediately freshens the cabinet and creates a moisture-resistant surface that’s easy to replace when needed.
Benefits of an under-sink mat
A well-made mat protects the cabinet floor from spills, stains, and small leaks. Contact paper wipes clean quickly and can hide worn finishes. In one case I discovered a slow leak only because the mat showed it first—my cardboard mat got soaked and sacrificed itself, saving the cabinet finish. When that happens, it’s a simple matter to replace the inexpensive mat.
5. Remove items you no longer use
Sort goods into keep, donate, and toss piles. Many under-sink items are rarely used: mismatched bottle tops, old dishcloths, or duplicate cleaning products. Clearing out what you don’t need immediately improves accessibility and reduces clutter.
6. Return items in a logical order and use containers strategically
Group like with like: trash bags together, cleaning sprays together, and dish-related items in one container. Place frequently used items near the front and less-used items toward the back. For deep cabinets, keep garbage bags behind the bins so you can reach them easily when changing the bag.
Reusable cloths and scrubbers can live in clear containers or small bins so you can grab what you need quickly. Refill containers with the items you actually use to avoid overcrowding other storage areas like towel drawers.
