Best Undersink Storage: Clearance and Capacity Guide

As an Amazon Associate we earn from qualifying purchases. Details

Space under a sink is shaped by the pipes, the trap and the cabinet back, so measure before you compare products. Note the usable width and depth and the height above the pipe run.

This set of six listings is mixed. Three are organizers made for under a sink, two are general stackable bins or drawers you could test in a cabinet, and one is a food container set built for another job. This guide says which is which.

Quick answer

Three of the six are made for under a sink. The FlagShip 2-tier rack expands from 17 to 25 inches wide and lists 25 x 11.5 x 15 inches with a 22 pound capacity. The Simple Houseware 2-tier tray is 5.5 in D x 16 in W x 11.25 in H and comes with 4 hooks. The Delamu 2 pack of pull-out organizers is 13.19 in D x 8.27 in W x 10.63 in H in its larger size. If you want stackable bins or drawers to try in a cabinet, the caktraie 5 Pack (16.6 in D x 13.1 in W x 7.32 in H) and the Vtopmart 4 Pack small drawers (7.5 in D x 6 in W x 4.4 in H) are the closest. The Rubbermaid pantry set was made for food.

Bins and drawers you could test in a cabinet

These two are general stackable storage with stated sizes. Neither listing mentions use under a sink, so treat them as bins to try, not as made-for-the-job organizers.

What it is: A 5-pack of stackable storage bins sold as a closet storage basket. The listing highlights a foldable, waterproof, multifunctional closet organizer. Color is White and the stated product size is 16.6 in D x 13.1 in W x 7.32 in H.

Who it suits: Someone who wants low stackable bins to try in a cabinet and has measured the space.

Pros

• Gives a full set of dimensions, so you can check it against your cabinet.
• Low height of 7.32 in leaves room to stack.
• Listed as foldable and waterproof.

Cons

• The listing does not mention use under a sink, so fit around pipes is unconfirmed.

• The size is an outside measurement, not usable interior space.

Skip it if: You need an organizer built to work around plumbing, or you want the material confirmed.

Buying checklist

• Measure the clear width and depth at the front and back of the cabinet, and note where the plumbing sits.
• Measure the height above the pipe run.
• Compare outside size with your space; the listings give outside size, not usable interior space.
• Treat any listing with no stated size as unconfirmed until you check the product page.
• Check that the exact variant you order matches the color, material and size you saw.
• Decide what you need to store and how heavy it will be before choosing.

FAQ

Are any of these made for under the sink?

Yes, three: the Simple Houseware tray, the FlagShip rack and the Delamu pull-out set list under-sink use. The caktraie and Vtopmart listings do not mention sinks or plumbing, and the Rubbermaid is a food container set, so you would be adapting those.

Which ones could work as small bins in a cabinet?

The caktraie 5 Pack and the Vtopmart 4 Pack are the closest, because they are stackable bins and drawers with stated sizes. Neither listing mentions sinks or plumbing, so measure your cabinet and the pipe area first.

Why do some listings give no size?

The Rubbermaid listing does not state product dimensions in the details we have. Check the product page for the size before you buy.

Should I use food containers for cleaning supplies?

The Rubbermaid set is designed for food, and the listing does not say it suits cleaning products. Look for a container that names the use you have in mind.

How do I check fit under a sink?

Measure the clear width and depth at the front and back of the cabinet and the height above the pipes. A unit that fits the cabinet on paper can still press against the plumbing once it is loaded.

Closing note

If you want undersink storage, start with the measurements of your own cabinet and keep only the listings that give a size you can check. The FlagShip, Simple Houseware and Delamu sets are the three made for it, the caktraie and Vtopmart sets are worth testing as general bins, and the Rubbermaid set is best bought for food.
