Kelli Kaufer Designs For the taller vanity I had the top of the sink at 38" which brought the vanity height to 34". The top of the other sink is at 36" and vanity top at 32". The width really depended upon how large the sinks were - I wanted them to have space to lay objects around the sink and if I remember right they are each 36" wide. Hope this helps! Good luck with your project, let me know how it turns out!!!!
