How to Organize Under a Bathroom Sink With Pipes in the Way

Step-by-Step

1. 1

   Step 1: Empty the Cabinet and Wipe It Down

   Take everything out so you can see the plumbing, cabinet floor, side walls, and underside of the sink basin. Wipe the cabinet clean before putting anything back.

   Pro tip

   This is also the easiest time to notice damp areas, stains, or products that have leaked.

   Step 2: Remove What Does Not Need to Live Here

   Discard empty packaging and products you no longer use, then move items that make more sense in another storage space. Keep this cabinet focused on things you actually need in the bathroom.

   Pro tip

   Reducing backstock often creates more usable space than adding another organizer.

   Step 3: Map the Pipes Before You Organize

   Look at where the drain trap, vertical drain, supply lines, and valves occupy the cabinet. Identify the usable zones to the left, right, front, and sometimes below the plumbing.

   Pro tip

   Treat the plumbing as the permanent layout and fit storage into the remaining spaces.

   Step 4: Measure the Usable Spaces

   Measure the width, depth, and height of the open areas where storage could actually fit. Include the sink basin hanging down from above, the position of the drain trap, door hinges, and anything else that reduces clearance.

   Pro tip

   Write down separate measurements for the left and right sides if the plumbing is off-center.

   Step 5: Create a Few Simple Categories

   Group what remains into useful categories such as daily personal care, hair products, cleaning supplies, extra toiletries, or guest supplies.

   Pro tip

   Keep categories based on how you use the bathroom.

   Step 6: Use Removable Containers Around the Pipes

   Place smaller items into bins, baskets, caddies, or other containers you already own, then position those containers in the usable zones beside the plumbing.

   Pro tip

   Test ordinary household containers before shopping for a specialized system.

   Step 7: Put Daily Items in the Easiest Positions

   Place frequently used items toward the front or in the easiest container to remove. Put occasional supplies and limited backstock farther back.

   Pro tip

   Accessibility matters more than perfectly symmetrical storage.

   Step 8: Check Access Before You Finish

   Make sure important plumbing remains visible and reachable without dismantling the entire storage system.

   Pro tip

   A little empty space around plumbing is useful space, not wasted space.
9. 9

   Step 9: Buy an Organizer Only if a Specific Problem Remains

   Use the cabinet for several days. If wasted vertical space or an unreachable area remains, use your measurements to choose an organizer that solves that specific problem.

   Pro tip

   The goal is not to fill the cabinet with organizers.

Tips

• Measure the actual open spaces beside and below the plumbing rather than relying only on the cabinet width.
• Use removable containers so you can lift out an entire category instead of reaching around pipes for individual items.
• Put taller bottles where the sink basin and plumbing leave the most vertical clearance.
• Keep frequently used items at the front and backup supplies farther back.

Common Mistakes

• Buying an under-sink organizer before measuring around the pipes and sink basin.
• Trying to fill every inch of space and making the plumbing difficult to inspect or reach.
• Using one large basket for unrelated products, which recreates the same digging problem inside the basket.
• Storing so much backstock under the sink that daily-use items become hard to reach.
