The cabinet under the sink is the hardest one in the house. A pipe runs right through the middle. It is dark. And whatever goes in first disappears forever.

I used to just shove things in and close the door fast.

The trick is to stop fighting the pipe and work around it.

These 12 under sink storage ideas do exactly that, for kitchen and bathroom cabinets alike.

12 Under Sink Storage Ideas

1Install a Pull Out Drawer System

A pull out drawer fixes the biggest under sink problem. No more kneeling and reaching blindly into the dark.

It slides forward on rails, so the stuff at the back comes right to you.

  • No more blind reaching
  • See everything
  • Smooth gliding rails

2Add a Bathroom Pull Out for Tight Spaces

Bathroom vanities are usually narrower than kitchen cabinets. A slim pull out fits where bigger units cannot.

Measure the space between the door frame and the pipe before you buy. Those few inches matter.

  • Made for narrow vanities
  • Easy access
  • Neat and slim

3Build with Drawer Slides for a Custom Fit

Under sink storage idea: build with drawer slides for a custom fit

Sometimes a ready made organizer just will not fit around an odd pipe. That is when a custom drawer shines.

Drawer slides let you build a simple box that fits your exact cabinet. In my experience it is easier than it sounds.

  • Fits any pipe layout
  • Totally custom
  • Smooth pull out

  1. Measure the cabinet width, depth and the space beside the pipe.
  2. Cut a plywood base and four low sides to fit that space.
  3. Glue and screw the box together.
  4. Mount one slide to each side of the box and the matching parts to the cabinet floor or side panels.

4Use a Two Tier Cabinet Organizer

A two tier organizer doubles your space. Instead of one layer of bottles on the floor, you get two.

The open frame fits around the pipe, not into it. Put tall bottles below and small items on top.

  • Fits around pipes
  • Easy to set up

  • Flexible layout
  • Fits odd spaces

8Hang Items on the Cabinet Door

The back of the cabinet door sits empty in most homes. An organizer there adds real storage.

  • No tools needed

9Keep Bathroom Items Sorted by Category

Under sink storage idea: keep bathroom items sorted by category

Bathroom cabinets collect everything. Hair products, skincare, cleaners and spare toiletries all fight for space.

Sort into labeled bins by category. Even two or three bins make a big difference.

  • Find things fast
  • Less clutter
  • Easy restocking

10Add a Lazy Susan for Hard to Reach Corners

A turntable solves the reach problem in deep cabinets. Spin, and the back bottle is now in front.

  • Spin and grab
  • Great for deep cabinets

12Use Clear Bins for Visibility in a Dark Cabinet

Under sink storage idea: use clear bins for visibility in a dark cabinet

Under sink cabinets are dark. Opaque bins mean pulling each one out to check what is inside.

Clear bins solve that. Lay a non slip shelf liner first to catch drips and keep everything from sliding.

  • See inside instantly
  • Protects the cabinet
  • Bins stay in place

Project Card · 30 minutes · Easy

Materials Needed

How to Make It

  1. Empty the cabinet and wipe it dry.
  2. Measure and cut the liner to fit the cabinet floor.
  3. Lay the liner flat, trimming around the pipe.
  4. Fill the bins by type and label the front of each.
  5. Place bins around the pipe, leaving the shutoff valves easy to reach.

PRO TIP Keep a small leak alarm or a dry paper towel at the back of the cabinet. If it is ever wet, you will catch a slow leak early. And if you have little kids, add a childproof latch for cleaning products.
