Start with what is under there besides your stuff
This cabinet is shared with plumbing. Before you plan anything, look at where the drain trap, the disposal, the dishwasher line, the shutoff valves and any reverse-osmosis filter or tank sit. Your storage fits around those, not the other way around.
Many Las Vegas homes have a water softener or reverse-osmosis system because the water is so hard. Those tanks take a large share of the cabinet, so measure the open space on each side carefully.
Waterproof the floor before anything goes back in
A silicone or ribbed under-sink mat with a raised edge catches drips and makes a slow leak obvious. It also protects builder-grade cabinet floors, which can swell from even small amounts of water.
Hard water leaves white mineral rings wherever drips dry. A mat you can rinse in the sink is much easier than scrubbing the cabinet floor.
Step by step
- Empty and inspect
Clear everything out and check for leaks, odors or water damage.
- Measure around the plumbing
Measure the usable width, depth and height on each side of the pipes and any tanks.
- Lay a waterproof mat
Trim it if needed to fit around the drain and supply lines.
- Install organizers
Add pull-out bins, a U-shaped shelf and a tension rod or door rack.
- Restock lightly
Return only daily cleanup supplies and move the rest to their own closet.
Choose organizers that work around the plumbing
Generic shelves rarely fit here. These options are designed for the awkward shapes under a sink.
- U-shaped or adjustable two-tier shelves that straddle the drain
- Narrow pull-out bins on each side, so you slide the whole bin out
- A tension rod near the top to hang spray bottles by their triggers
- A door-mounted rack for sponges, brushes and gloves
- A small caddy for the supplies you carry to other rooms

Keep only what belongs at the sink
This is the cleanup zone, so stock it with dish soap, dishwasher detergent, sponges, a few cleaning sprays, trash bags and a brush. Bulk refills belong in a cleaning supply closet or laundry room.
If young children live in the house, use a cabinet lock or move harsh chemicals to a higher cabinet. Keep everything in its original, labeled container.
| Keep under the sink | Store elsewhere |
|---|---|
| Dish soap and dishwasher tabs in use | Bulk detergent boxes |
| Two or three all-purpose sprays | Specialty cleaners used monthly |
| Sponges, brush, gloves | Extra sponges and paper towel rolls |
| One roll of trash bags | Backup trash bags |
Leave access for repairs and check monthly
Never block the shutoff valves. In a leak, you want to reach them in seconds without pulling out three bins first. Choose organizers that slide out easily for that reason.
Once a month, pull the bins forward and look for drips, mineral crust on fittings or a damp mat. Catching a slow leak early is far better than discovering a ruined cabinet floor. For the broader kitchen layout, see how to organize kitchen cabinets.
