You do not have space for the counter faucet behing the sink .You need to be able to have the counter have a hole cut and you need to ba able to clean behingd it . Simple math . How wide is the cabinet ? Maybe look at a trough sink with the faucet on the side .

perhaps looking at the specification sheet will help…

American Standard Studio Sink

Sounds like a smaller sink or wall-mount faucet are options.

Why have you selected an undersized vanity for this room? That is where the problem lies.

"F" in the above drawing is 16 5/8". If the front of the sink flange starts at the rear of the cabinet rail, that leaves 3 3/8" from the rear of the sink flange to the rear of the cabinet, which is plenty of room for a faucet, even with a splash.

I think it sounds like you have the smaller studio sink (0614) and I can't see why that would be a problem..

My daughter used a Toto ( LT542G ) that fit in a 20 inch deep cabinet box with room to spare
