An under-sink cabinet can already be awkward, but adding a garbage disposal makes the layout even more challenging. The disposal body, drain pipes, water lines and shutoff valves all reduce the open space you can use for storage.
The good news is that you do not need a perfectly symmetrical cabinet to create an organized setup. The most effective approach is to work around the disposal, protect access to plumbing and use the remaining vertical space intentionally.
1. Empty the cabinet completely
Start by removing every bottle, sponge, bag and cleaning tool from the cabinet. This gives you a clear view of the disposal, drain pipe, water lines and usable floor space.
It is much easier to plan storage when you are looking at an empty cabinet instead of trying to organize around existing clutter.
2. Identify the disposal footprint
A garbage disposal usually takes up a large section directly beneath the sink drain. That means the center of the cabinet may have less usable height and depth than the sides.
Instead of trying to fit one large organizer across the entire cabinet, think of the space as separate zones:
- Left side of the disposal
- Right side of the disposal
- Front area near the cabinet doors
- Any shallow space behind or beside plumbing
3. Measure the usable space, not just the cabinet size
Cabinet width alone does not tell you whether an organizer will fit. You need to measure around the disposal and plumbing.
Check:
- Usable width on each side
- Depth from the cabinet front to the pipes
- Height below the sink bowl
- Clearance around the garbage disposal
- Door and hinge clearance
For a complete measuring checklist, see our Under Sink Organizer Cabinet Size Guide.
4. Keep the garbage disposal accessible
Do not pack storage tightly against the disposal unit. Leave enough room to see the unit and access the area around it if maintenance is ever needed.
You should also keep shutoff valves and plumbing connections visible and reachable.
5. Use the open side zones
The most useful storage area is often beside the disposal rather than directly underneath it.
A narrow organizer can make better use of one side of the cabinet while leaving the disposal area open. This is especially useful if the cabinet has good vertical clearance beside the plumbing.
6. Add vertical storage where height is available
If the side of your cabinet has unused height, a two-level organizer can turn that space into practical storage.
The KOOVEXO 2-Tier Pull-Out Under Sink Organizer is designed to create two storage levels while keeping everyday products easier to reach.
Before choosing any organizer, always confirm the product dimensions against your own cabinet and disposal layout.
7. Use pull-out storage for deep side spaces
Cabinets with garbage disposals can leave narrow but deep spaces along the sides. These spaces are useful, but products at the back can be difficult to reach.
A pull-out design helps solve this problem by bringing the contents forward instead of forcing you to reach around bottles and plumbing.

8. Keep large bottles on the lower level
Large cleaning sprays, dish soap and refill bottles are usually easier to manage on the bottom tier. Smaller accessories can go above them.
This reduces the amount of stacking and helps you see what you already have.
9. Use the upper level for smaller essentials
Good candidates for an upper tier include:
- Sponges
- Cleaning cloths
- Dishwasher tablets
- Gloves
- Small brushes
- Garbage bag rolls
Keeping these smaller products separate prevents them from disappearing behind taller bottles.
10. Avoid storing too many backup products
A cabinet with a garbage disposal has limited capacity, so avoid turning it into a bulk-storage area.
Keep the products you actually use in the under-sink cabinet and move extra backup stock somewhere else if space becomes crowded.
11. Leave room to inspect for leaks
Under-sink cabinets should not be packed so tightly that you cannot see the cabinet floor or plumbing.
Leaving some open space makes it easier to notice moisture, drips or damaged packaging early.
12. Group items by function
Instead of mixing everything together, create simple categories such as:
- Dishwashing
- Surface cleaning
- Sponges and cloths
- Garbage bags
- Backup supplies
Clear zones make the cabinet faster to use and easier to reset.
13. Keep the most-used products toward the front
The items you use every day should be easiest to reach. Dish soap, dishwasher tablets and your most-used cleaner should stay near the front.
Backup products can go farther back or on the less accessible side.
14. Organize around plumbing, not against it
The most successful under-sink layouts accept that pipes and disposal units are fixed obstacles. Trying to force one large shelf into the cabinet often wastes space.
Instead, use smaller zones and flexible storage solutions that fit around the plumbing.
You can find more layout ideas in How to Organize Under the Sink Around Plumbing and Pipes.
15. Recheck the layout after a few days
Once your cabinet is organized, use it normally for a few days and pay attention to what feels inconvenient.
If one product is difficult to reach, move it forward. If one tier is overcrowded, reduce the number of items stored there.
A good organization system should fit your daily routine rather than look perfect only on the first day.
Frequently Asked Questions
Can I use a 2-tier organizer if I have a garbage disposal?
Possibly. It depends on the organizer dimensions and the amount of open space beside or around your disposal. Measure the usable cabinet zones before ordering.
Where should I put an organizer in a cabinet with a disposal?
The open space beside the disposal is often more practical than the center of the cabinet. The exact placement depends on your plumbing layout.
Should an organizer touch the garbage disposal?
It is better to leave some clearance so the unit and surrounding plumbing remain visible and accessible.
What should I store under the sink when space is limited?
Prioritize frequently used dishwashing and cleaning supplies. Move excess backup products to another storage area when possible.
How can I reach products at the back of a narrow cabinet?
Pull-out storage or removable bins can make deep side spaces easier to access.
How often should I check the under-sink cabinet?
A quick check every few weeks can help you remove empty products and notice moisture or leaks before clutter builds up.
Make the remaining cabinet space work harder
A garbage disposal reduces usable under-sink space, but it does not make good organization impossible. Measure the open zones, keep plumbing accessible and use vertical or pull-out storage where it fits.
If your cabinet has enough clearance beside the disposal, explore the KOOVEXO 2-Tier Pull-Out Under Sink Organizer as one option for creating two accessible storage levels without remodeling the cabinet.
