1. Pull-out caddy (8-inch)

W 7.7″ × D 16.4″ × H 5.3″ · from the product page

A slim caddy that rolls out so you can reach the back of the cabinet without kneeling in it. It is 7.7 inches wide and 16.4 inches deep, and 21.3 inches long with the basket pulled out.

Good for

  • Spray bottles, sponges and cloths
  • Gaps beside a pipe or a garbage disposal

Skip if

  • Your cabinet is shallower than 16.4 inches
  • You store tall jugs, since the caddy is only 5.3 inches high

2. Under-sink turntable

W 12″ × D 12″ × H 3.3″ · from the product page

One spin brings the back of the cabinet to the front. At 12 inches across, it needs a clear patch of floor with no pipe running through it.

Good for

  • Cleaner bottles you reach for often
  • Cabinets with a flat, open floor

Skip if

  • A pipe crosses the middle of the space
  • The door opening is narrower than 12 inches

3. Two-tier sliding baskets

W 8″ × D 14″ × H 12.8″ · from the product page

Two wire baskets stacked on rails slide out like drawers, so items at the back of the cabinet come to the front. It is 8 inches wide, 14 inches deep and 12.75 inches tall, so check the height to the lowest pipe before you buy.

Good for

  • Cans, spice jars and cleaning supplies
  • Narrow, tall gaps beside a pipe

Skip if

  • The cabinet is shallower than 14 inches inside
  • Less than 12.75 inches of height is clear above the floor

4. Door-mounted bag dispenser

W 10.6″ × D 6.7″ × H 10.3″ · from the product page

A steel bracket hangs the dispenser over the cabinet door, up to 0.75 inches thick. It holds a roll of 13-gallon kitchen bags and uses the door instead of floor space.

Good for

  • Kitchen bags within reach
  • Cabinets already full of bottles

Skip if

  • Your cabinet door is thicker than 0.75 inches
  • You use bulk rolls of bags, which do not fit

How to measure under a sink

Take everything out and write down three numbers for the space where an organizer would sit.

  • Width: the door opening, not the inside of the cabinet. Anything you buy has to pass through the door first. Measure the inside too, and use the smaller number.
  • Depth: from the door frame to the back wall. If a pipe or the disposal sits in the way, measure to it instead.
  • Height: from the cabinet floor to the lowest pipe, the disposal or the underside of the sink, wherever the space is tightest.

Round down to the nearest quarter inch. An organizer that is exactly the size of the gap is hard to slide in and out.

Before you buy

Look at where the drain pipe and the water supply lines run. A turntable needs a clear circle, and a pull-out shelf needs a clear path to slide along. Leave room to open the door fully with the organizer in place.

FAQ

Should I measure the cabinet or the door opening?

Both. Take the smaller number, because the organizer has to fit through the door before it can fit inside.

Can I use a turntable with pipes in the way?

Only if a clear circle of floor is left. A turntable cannot turn past a pipe, so choose a pull-out caddy for the gaps beside the pipes instead.
