Best Way to Organize Under Bathroom Sink

As an Amazon Associate we earn from qualifying purchases. Details

The space under a bathroom sink is awkward because the plumbing takes the middle, the door opening is narrow, and the items stored there range from tall bottles to small tubes. The best way to organize it is a short sequence rather than one product: empty and sort the cabinet, check the pipes for leaks, measure the usable space around the plumbing, then add organizers that fit those measurements. This guide walks through that sequence and uses three Amazon listings, an L-shaped pull-out, a stackable set of drawers and a clear tiered set, to show the numbers to compare. It includes a worked measuring example, the storage-safety points from Poison Help, and the places where the listings contradict themselves.

Quick answer

Empty the cabinet, throw out what you do not use, and group what is left. Measure the width, depth and height of the opening and the position of the pipes. Then pick organizers whose stated minimum cabinet size is smaller than your measurements: the REALINN L-shaped pull-out lists a minimum of 11 in wide, 15 in deep and 16 in high. Keep cleaners and medicines in a locked cabinet or out of reach of children, and never mix household products.

Step 1: empty, clean and sort

Home-advice site Real Homes quotes organizer Mary Cornetta, founder of Sort and Sweet, in its tips on this job. The first tip is a clear-out: empty the cabinet, clean the space, remove anything that does not belong, and keep only bathroom-related items. The second is to sort items into categories and use labels, especially if several people share the cabinet, and to review the space every few months. The article is at realhomes.com. The page we opened was truncated after the first two tips, so we cite only those.

Step 2: check the pipes before you load anything

The cabinet holds your shutoff valves, supply lines and trap, so a slow leak can go unseen behind bottles. The US Environmental Protection Agency’s WaterSense program advises examining faucet gaskets and pipe fittings for water on the outside of the pipe to check for surface leaks. It also says a faucet dripping once per second can waste more than 3,000 gallons a year. Read it at epa.gov. Look and feel along the pipes with the cabinet empty. If anything is wet, fix it before you add organizers.

Step 3: store chemicals and medicines safely

The Poison Help site from the US Health Resources and Services Administration says more than 90 percent of poisonings happen in homes, mostly in the kitchen, bathroom and bedroom. Its advice is to keep household cleaners and potentially poisonous substances in locked cabinets or out of the reach of children, keep products in their original containers, never store chemicals in food containers, never mix household products because that can create a dangerous gas, and keep laundry products locked up. The Poison Help line is 1-800-222-1222. See poisonhelp.hrsa.gov. An under-sink cabinet sits low, so out of reach does not apply to it unless the door locks. That is our reading of the page, which does not mention latches.

Step 4: measure the usable space

Measure the width and height of the door opening, then the depth, then the position of the drain, the trap and any supply lines. Write down the clear space on the left and right of the plumbing separately. Most organizers list a minimum cabinet size, and that is the figure to compare. The three listings below show three ways of working around pipes.

Option A: L-shaped pull-out for pipes

Option B: small stackable drawers

Option C: clear tiers with dividers

Worked example

For example, suppose the opening is 24 in wide, 18 in deep and 20 in high, with the drain pipe in the centre. The REALINN needs 11 in wide, 15 in deep and 16 in high for one unit, and 22 in wide for two, so two units fit with 2 in to spare, provided the pipe does not block the narrow top baskets. Three Vtopmart units at 7.5 in wide total 22.5 in, which leaves 1.5 in. At 10 in high each, they leave 10 in of clear height in a 20 in opening. These are planning numbers from the listings, not a tested fit. Put a tape measure on the real cabinet before you buy.

Step 5: put the heavy and the often-used where they belong

Keep the most-used items at the front and the ones you rarely touch at the back. Heavy items belong low, so a loaded top drawer does not tip a pull-out; the Vtopmart listing’s 15 lb top-drawer figure is a reminder that the top tier has a limit. Use labels if more than one person reaches in, as the Real Homes expert suggests.

Mistakes to avoid

• Buying before measuring around the pipes.
• Trusting one number when the listing has two, as with the REALINN width.
• Storing chemicals in a cabinet that does not lock when children are in the home.
• Mixing household products or moving them into food containers.
• Loading organizers over a slow leak.

Frequently asked questions

What is the best way to organize under a bathroom sink?

Empty and sort the cabinet, check the pipes, measure the usable space around the plumbing, then add organizers whose stated minimum cabinet size fits.

How do I work around the pipes?

Use an L-shaped pull-out such as the REALINN, whose narrow top basket mounts left or right, or place small units on either side of the pipe.

How much weight can an under-sink organizer hold?

The REALINN lists 50 lb in total, the Vtopmart lists 15 lb for the top drawer, and the Delamu listing states no rating.

How should I store cleaners and medicines?

Poison Help advises locked cabinets or out of the reach of children, original containers, and never mixing products.

Should I check for leaks first?

Yes. The EPA advises examining pipe fittings for water on the outside of the pipe.
