The cabinet under the kitchen sink is where good intentions go to die: half-empty bottles, three sponges, a leaking dishwasher tablet bag and pipes in the way of everything. The good news is that it's a small space, so it takes about 20 minutes to fix properly.

Step 1: empty everything

Take everything out. All of it. Put it on a towel on the floor so you can see what you actually have.

Step 2: check for leaks and clean

With the cabinet empty, run the tap for a minute and look at the pipes and the cabinet floor. Water damage under sinks is common and slow - catching it early saves a lot of money. Then wipe the cabinet out and let it dry.

Step 3: declutter ruthlessly

Keep only what you use at the sink: dish soap refill, dishwasher tablets, sponges, cloths, a couple of cleaners and trash bags.

Step 4: protect the floor

A waterproof cabinet mat with a raised edge catches drips and small leaks before they reach the wood.

Step 5: add storage that works around the pipes

The pipes are the main problem. Two kinds of organizers solve it:

Two-tier sliding organizers sit on either side of the pipes and double the usable height. Pull-out drawers mean nothing gets lost at the back.

Adjustable shelves with removable sections fit around the pipe at any height.

Extends to fit the cabinet and has cut-outs for pipes.

Step 6: use the door

A small caddy or adhesive hooks inside the cabinet door hold sponges, brushes and rubber gloves so they dry properly instead of getting musty in a corner.

Step 7: hang spray bottles on a tension rod

A tension rod across the top of the cabinet is the classic trick: hang spray bottles by their triggers. They're visible, upright and take no floor space.

Step 8: group and label

Give every category a zone - dishwasher supplies in one drawer, cleaners in another, bags and sponges on the door. A small label on each drawer keeps the system working when other people put things away.

Safety note

If you have small children, use a cabinet lock and keep strong cleaners on the highest tier. And never store bleach next to ammonia-based or acidic cleaners - if they leak and mix, they release dangerous fumes.

Keep it tidy

Add "check under the sink" to your monthly routine and use a supplies inventory before shopping, so you never end up with four bottles of glass cleaner again. Both are part of the Home Reset Planner.
