Reset the space first
Trace the pipe footprint
Place paper on the cabinet floor and mark every pipe, hinge and obstruction. Measure the clear rectangles left on both sides rather than the cabinet as one empty box.
Put daily items on a pull-out
Dish tabs, sponges and spray bottles belong on the easiest tray. Refills and rarely used cleaners can stay in a handled bin behind or beside it.
Protect the cabinet floor
Use a washable liner or shallow leak tray. It is cheaper than repairing swollen particleboard and makes the entire zone easier to reset.

QUICK ANSWERS
Questions readers ask
What is the most important under-sink measurement?
Map the pipe, disposal and shutoff-valve footprint first. The remaining clear rectangles determine whether a pull-out or two narrow caddies will fit.
Can renters install an under-sink organizer?
Yes. The layouts here use freestanding, no-drill modules and a removable liner rather than permanent hardware.
