I'm just going to have to go from memory and what the normal was, but a normal vanity cabinet is 21" deep, so we would normally make the shorter makeup area 3" shallower at 18" deep. The standard height for the makeup area was at table height of maximum 30" at top of counter, with the countertop being anywhere from 3/4" to 1 1/2", so the actual height of the cabinet is usually 28 1/2". The standard width for foot and leg room is 24". It appears to me that the drawer cabinet is about 15". Your countertop usually extends beyond the front of the cabinet 1" to 1 1/2". I hope this helps!

what is the total length of this vanity and makeup area? Looks perfect for our plans!!

What is the height of the stool?
