Pro Tips

✓ Measure your cabinet opening including pipe locations before buying — most organizers are not returnable once cut
✓ A tension rod across the middle of the cabinet turns unused vertical space into spray bottle storage
✓ Stackable pull-out drawers on one side and a tension rod on the other maximizes awkward under-sink space
✓ Line the cabinet floor with waterproof shelf liner to protect against drip damage
✓ Clear bins let you see what's inside without moving everything — worth the small extra cost
