Measure the unusable space first
- Measure the cabinet’s interior width, depth, and height—not the outside.
- Mark the drain pipe, disposal, shutoff valves, and door hinges on a quick sketch.
- Measure the largest item that must live here, usually a spray bottle or refill jug.
Subtract the pipe zone from the cabinet rather than pretending the whole rectangle is available. That one change prevents most failed purchases.
Choose a layout by constraint
For centered plumbing: two narrow pull-out units
A matched pair can flank the drain and keep frequently used items accessible. Confirm that each drawer clears the door frame when extended.
For off-center plumbing: one L-shaped shelf
An L-shaped frame uses vertical space without forcing bins behind a pipe. Favor removable trays over fixed baskets because leaks eventually happen.
For crowded valves: handled bins only
Skip rigid shelving. Two or three washable bins are easier to lift out when a plumber needs access.
Our pass/fail checklist
- No drilling and no pressure against pipes.
- Can be removed in under 30 seconds.
- Bottom surface catches or reveals leaks.
- Daily products are reachable without moving another product.
- Dimensions are published clearly enough to compare with your sketch.
Do not store paper goods, pet food, or anything moisture-sensitive directly beneath a sink unless it is in a sealed container.
