Vanity Combo Cabinets – Drop-In Sink Clearance

There are two important measurements to consider, depending on what you are trying to fit above the drawer:

• True drawer clearance:
  • Approximately 8.25"
  • This is the maximum clearance for items that might be taller than the drawer box itself.
• Total vertical clearance (drawer top to cabinet top):
  • Approximately 11.5"
  • This is the full space available above the top drawer box, which is often relevant for sink bowls and plumbing components.

📌 What this means:
 If a drop-in sink or plumbing component extends below the countertop:

• Anything extending below 8.25" may interfere with the items in the drawer box
• Items up to 11.5" may fit above the drawer, depending on sink shape and plumbing layout
