I have a vanity top ordered like 336-765 (Home Depot Number). It is a 61 inch double sink made from cultured marble. Color White. I Know that the number is for the white onyx version but that is the only difference. I want to know the measurement in inches from the left edge of the top to the Center of the drain for the left hand sink. I want the same dimension in inches from the Center of the drain of the right hand sink to the right edge of the vanity top. Thank you, Doug

I want to know the measurement in inches from the left edge of the top to the Center of the drain for the left hand sink you got to be kidding! Give me a blueprint of the vanity and I'll be glad to answer your questions.
You don't need all that information. What are you trying to find out?
If this were my job I would install the cabinet and put a continuous waste on each drain and connect the waste to a trap and then out the wall. Good luck, Tom

You can find that in your house but we have no idea.

Obviously the right and left are symmetrical.
The bowls are 13" wide each. That leaves 35". The middle section appears to be 13", which would be normal because many bases have a 12" wide drawer section, and the edge sections appear to be 11" each. That adds up to 61.


So 11" + half of 13" = 17 1/2" to the center of the drain from the edge of the top on each side.
Approximately. Why on earth does it matter so precisely?

Nice catch! You went the extra mile and pulled the tech specs up from Home Depot. We figured all the OP needed was a ruler and he can take the measures himself. Nice work, Tom

No HD never puts vanity top specs like that on their site. I guessed.
OP doesn't have the top yet. He is freaking out anyway.
Maybe his drains are chrome.
