The cabinet under a bathroom sink is awkward: pipes in the middle, a low ceiling and bottles that fall over. Most people give up and use it as a dumping ground. The right organizers work around the plumbing and turn dead space into storage, but only if they fit, so measure before you buy.

Measure first
Measure the width, depth and height of the cabinet, and note where the pipes run and how tall the highest point is. Also measure the gap between the sink bowl and the cabinet floor. A shelf that is a little too wide will not go in at all, and one that is too tall blocks the door.
Shelves and bins
A two-tier shelf
A shelf that works around the pipes gives you two levels in a space that was one. It suits cleaning supplies and spare toiletries. Plumbing varies a lot, so compare the dimensions against the cabinet.

A slide-out organizer
A two-tier unit with sliding baskets lets you pull out a whole category at once instead of reaching to the back. It suits hair products, first aid or spare toiletries. Measure the cabinet width and the pipe position first.

A basket for towels
Rolled towels in a basket look neat and are quick to grab. It suits a bathroom with no linen closet. Check that it fits the space under the sink and not only on a shelf.

Jars for small items
Cotton pads and swabs are better in jars than in loose bags. Jars with lids keep them clean. They look pretty on the counter or stored in a bin under the sink.

Around the sink
An over-the-toilet shelf
If the cabinet is full, the space above the toilet can take towels and spare products. It frees the cabinet for cleaning supplies. Measure the toilet tank height and the ceiling.

A shower caddy
Moving shampoo and soap into the shower frees cabinet room. Rustproof stainless steel lasts longer than plastic. Check that it fits your showerhead or corner.

A cleaning supply container
Decanting bulky bottles into a tidy container saves space and looks calmer. It suits households that buy in bulk. Label it clearly, especially if children are around.

A vanity tray
A tray on the counter collects the daily items and keeps them off the cabinet shelves. It makes the vanity easy to wipe. A narrow one suits a small sink.

Keep it safe
Store cleaning products out of reach of children and pets, and keep anything you use daily at the front. A quick tidy every few months stops the cabinet from filling up again.
