as title, what is the depth of your vanity top. from wall to the edge of vanity.

Yeah... no standard, only typical. If u want to build it 1m also can

mine is 450mm because i have small bathroom

thx bros. bcos my contractor told me standard is 450mm which i think is too small. what i usually see is 500~550mm like tanslee mentioned above

My master toilet top is 500mm. My common toilet top is 420mm. Cannot go beyond 420mm or else the full extension drawers will hit the WC coz they are facing each other. This is one aspect you need to consider.

thanks for reminding.

For Vanity top or kitchen, standard is alway not more then 600mm.
